Brian Theoret Yes the settings will be identical aside from Offset and Additional Turbo Voltage since all CPU's will require a different amout of Vcore to remain stable.
Found a desktop computer recently at my local supermarket recycling center that had this (Z77) motherboard in it. Fully working. 🤔😎😇😆👌👍 Upgraded its stock CPU (i5-3450) by putting in an Intel Core i7-3770 CPU & 4x 8 GB DDR3 1600 MHz Kingston RAMs.
Thanks for the guide was able to get stable 4.6 Ghz although under prime loads the temps reached 90 but I have been using my old H60. The vcore reached 1.45 during prime which is insane but under real world scenario the max temps saw was 70 which seems fine.
I have pretty much the same setup, although im staying at 4.0 GHz. Don't see any need to increase even more and shorten lifetime. Even though is not so new :P
Thank you. Additional turbo voltage only increases your full load vcore. Offset will increase both your idle and full load vcore. By using both together you can have your CPU idle at a Vcore that is similar or lower then stock and still be able to stabilize your full load vcore. If you use offset by itself (Additional Turbo Voltage on Auto) you will not have any control over you idle vcore. I will try and get another video up soon :)
Raian Senpai Offset controls both the Idle and full load vcore. Turbo will add additional voltage to the full load vcore that you get from the offset. What multiplier are you shooting for? What is your offset set to and what is your current idle vcore in CPU-z?
I have a i5-3570k base speed @3.4 I followed the video and everything went to bios changed everything like u did in the video and save the file and loaded it well I started my computer up and it’s still at 3.4ghz @maximum Vcore
Thanks for the video. It was really helpful! I have one question, if you have time. Most people on here are talking about their vcore being a bit high, but mine is a bit lower and I'm wondering if there's any downside to that? My vcore seems to be hovering around 1.28 to 1.30 with a 45 multiplier, -0.005 offset and +.078 turbo volt. Everything seems stable after about an hour of prime95. Should I try to get my vcore closer to 1.35? Or is it fine where it is? Thanks again!
Thank you for the tutorial. I see that you install linux on an asrock motherboard. I am using a z77 and I can't install a linux operating system on my motherboard. any suggestions ? 🙃
I had separate drives for windows and Linux, then had to go into Linux terminal and sudo update grub otherwise you won't be able to select which is you want to boot in to
hello, thank you for the tutorial, it was helpful. I have a question, my core voltahe at full load is around 1.3v but my VID is 1.42v, I am not sure what VID is but 1.42v seems too high for me and im afraid it will damage the processor.
Hello, VID is what voltage the processor "thinks" it will need to be stable at X overclock. VID is not the voltage being applied. Only focus on the Vcore displayed in CPU-z as that is the voltage that your processor is receiving.
I know it has been a long time, but I still have an i7 3770 (non K). Built it with an old AsRock z77 Pro3. Trying to OC it. My settings are: 42 multiplyer; BCLK 100.0; Additional Volt. +0.055V; Limits: 300-300-250-250; No Offset. When on CPU-Z, it doesn't reach 4.2 Ghz, but 4.1(ish). Stressed, did some tests... rock solid (so far). My cooler is a very good air cooling system (65 degrees C when stressed). I'm trying to reach 4.2 Ghz, but no further. What did I do wrong?
@@Lucky223 Before that I OCd it to 4.2, but messing with the BCLK. I just saw a video someone OCing the 3770 (non K) to 4.3 Ghz, without messing with de MoBo BUS. Gonna make more tests. If it's possible, I'm gonna try to reach 4.5 Ghz.
SKazclaw Hello SKazclaw , Offset will produce an idle and full load Vcore. It will also Increase/Decrease your Idle and Full load Vcore depending on what it is set to. Example 1: A +0.005 offset will have a higher idle and full load Vcore then a -0.005 Offset. Additional Turbo Voltage will only increase your full load Vcore and does NOT affect Idle Vcore. Its basically an "In Addition To" the full load Vcore provided by Offset. How Offset works: Example 2 Lets say you have Offset set to +0.005 (Turbo on Auto and say Auto = 0.000v). CPU-z displays idle Vcore at 0.96v and Full load at 1.350v during Prime 95. How Additional Turbo Voltage Works: Now lets say you change Additional Turbo Voltage from Auto (0.000v) to +0.004v and leave your Offset at +0.005. Now your Full Load Vcore during Prime 95 will be 1.354v. This is how Offset and Additional Turbo Voltage works but I am also simplifying it and not accounting for Vdroop to make it easier to understand. Does this make sense? :)
Maximum Vcore Thank you for the detailed response Vcore. I have my system OCed to your settings currently. With your help now, and with some research I did last night, I am going to give it a shot OCing it myself.
Any idea why my z68 pro 3-m doesn't want to go over a ratio for all core about 37? I have a 2500k inside and as far as I can tell both the CPU and the Mobo should be able to overclock. Whatever i fill in over the value of basically 3700mhz, will just default back to a max of 3700mhz.
Running an ASRock Z77 EXT. 4 w/2600k this board will not let me enter a multiplier of x38. Seen lots of folks with this issue but no solution. Old MB ASUS P8P67 LE and i could get over 5 Ghz out this beast on an H70 in push-pull. As is I sacraficed a PCI-E lane for my 1060 6Gb. If someone knows then hit me up please.
The offset voltage controls your idle and full load Vcore. Additional turbo voltage is additional mv added to the full load vcore produced by the offset. You most likely had to increase offset because your OC was unstable. Possible the idle vcore was also too low.
Thank you for your video. I did exactly what you did. However, the CPU-Z is showing *16 (16-46) and *46 (16-46) alternatively. Did I successfully overlock my i5-3570k to 4.6 ghz?
i've upgraded to 2600k from i5 3450.. and i have the board z68 extreme4 gen 3. i can change the core ratio. if i typed 44 it would always go back to 38. what seems to be the problem? thanks

Hello, I need your help, take apart the whole pc and clean it, then to fix now don't directly start Windows without having to touch F1. I always get this selector, my pc is asrock G41M-VS3. please help me, thanks.
I have Asrock z87 extreme4 Intel i7 4770k 3.5ghz (stock) Cooler Master Hyper T4 I did stress test on its stock clocks using IntelBurn test and Core Temp to monitor its temperature. It passed the test on full load but showed significant increase in temp. here are the results of the max heat: Core#0 82c Core#1 86c Core#2 85c Core#3 79c Do you think I can tweak it up to 4.0 and keep it running at that speed using the same method? (its max boost technology pushes it up to 3.9 and I think at this speed I gave the results above).
Hi! Thanks for the great tutorial! I'm having a little high vCore with this, something around 1.35 - 1.45v on full and 1.1v on idle. the temp is around 60C How can I decrease this vCore, since there is no fixed vcore setting available? I have the asrock z77 Pro4 with i7 3770k Cooler Corsair H105
Acupuntura Fabio Athayde Curitiba Ok, well the Offset and Turbo will be different for all CPU's and multipliers. I am not sure what multiplier you have but if you want to reduce your your full load vcore then you will need to reduce the additional turbo voltage. An idle Vcore of 1.1v is still a little high so you can also try for a higher negative offset such as -0.015, -0.020 ect. Changing the offset will will affect both your idle and full load vcore even if no changes are made to Additional turbo voltage.
I'm sorry, Ive been meaning to make another but have been busy. I'll do my best to get another video made for Offset & Additional Turbo Voltage. If you have any questions, you can post them here :)
Hi there. I'm using Z77 Pro 3 too. But at "CPU loadline calibration" setting there's no option as "Level1" ,"Level2", ...... There ara only %0 , %50 and %100 options. What could the resaın be for this difference ?
sisi se puede. el overclock de la placa de video se configura desde la bios pero es aparte. todo tambien depende de la refrigeracion que le pongas al procesador.
I have the exact same hardware as you aside from the ram I'm using which is 1333 PNY but I don't seem to have a XMP option above the ram frequency. Should I just leave it on auto and not worry or am I missing something.
XMP is only for the stock speed of the RAM. If you select the XMP profile, it will set you speed (1333), timings and voltage, so you really don't need to touch any of these settings. If overclocking your RAM then you will need to set it up manually without XMP. You should see other frequencies listed under DRAM frequency.
Why does my corespeed not stable at 4689? it goes back to 1599 and sometimes goes to 3k+ .. and btw, my windows in system properties wont show that i overclocked it to 4.6, i am using cpuid and i am on i7 2600k.. and i dont have any problems on 4.6 OC , no blue screen or crash but just on Corespeed i saw it goes up & down. Thanks
Nightingale Nightingale Look at my reply to kathness24. If you are not stable at 4.7ghz during Prime 95 then you will need to increase the Additional Turbo Voltage.
What is SAFE Overlock Settings For ASROCK H61DE/S3 Sandy bridge i7 2600k 3.40ghz? 8gb DDR3 I want to Overlock CPU RATIO SAFELY to x38 Please Tell me the suggested settings: CPU Voltage Offset: DRAM voltage: PCH Voltage: VTT voltage: CPU PLL Voltage: VSSCA Voltage: IGPU offset voltage:
I can't tell you. The Max OC is different for every CPU and Motherboard. You'll need to slowly bump up the multiplier to find out what kind of OC you can achieve.
Hi! Thanks for video! I did exactly what you asked for , but temperatures reached 85 degrees (24 hours in Prime95 - Blend ) . Is there anything I can do to reduce them ? I have a Z68 Fatalyt1 Pro + Seidon 120M + i7 3770k@46
Celso Junior Hello Celso, 85c during Prime95 blend is not bad at all especially since the 3770K throttles at 98c. Also the temperatures you reach during Prime 95 are no where near the every day load temperatures of the CPU. Your gaming temperatures will probably be around 65c +/-. Honestly if Prime 95 passed a 24 hours blend test w/out a worker failing or any whea errors then your OC is stable. If you would still like to reduce your full load temperatures then you will either have to upgrade you CPU cooling or reduce you OC to 4.4-4.5ghz and decrease your Vcore.
FunkyBallcat Hello FunkyBallcat, It is an Asrock Extreme 3 Gen 3 (2.30 Bios) w/ a 2500k CPU. Yes a EVO will be good for overclocking your CPU, probably up to 1.30v to 1.35 Vcore.
The starting point for is always +0.005 offset / +0.004 turbo. If the system boots into windows, open CPU-z and see what the vcore is when the CPU is at a 16 multiplier. This will be your idle vcore. Then start up a stress test for a minute to get a estimate of your full load vcore. Idle vcore should usually be ~.90v to 1.00v. If your idle is higher then this, then go negative offset until its in this range. Last, increase your full load vcore with additional turbo voltage until your OC is stable during stress test.
why is asrocks so complex my old msi board was so good you set the voltage to what you want and the multiplier and your done never had a problem with it.
Well, you can still do that on this board. That is called a fixed OC but that is not what I'm showing in the video. The video is showing how to setup Offset / Turbo so that your OC (multiplier and voltage) will scale depending on the load. I guess compared to fixed, yes its a little bit more complicated.
Maximum Vcore I tried a fixed overclock but the voltages were never what I put in I know the voltage my cpu takes for a 4.5 ghz overclock but when I do that with the asrock board the voltages were all over the place and the system was very unstable the msi board I used a fixes voltage and I put in 1.345v and that is what I got asrock board you need to play with that load line calibration but no matter what I set it at it still did not give me the right voltage and even spiked to voltages I do not deem safe for the cpu. my msi board was an expansive board designed for overclocking and it did a fucking amazing job it make me cry every time lel. I have got my overclock working tho now just to let you know but fuck it was a job and a half to get it. and your video was very helpful
Nice thanks. What is your vcore with these settings? I have z68 pro 3 + i5-2500k and with these settings vcore goes up to 1.380. Temps max at 75 with prime95 so this doesnt' seem bad. I'll see if this is stable for me and maybe start dropping additional turbo voltage 0.005 at a time, or should I drop offset voltage?
Maximum Vcore Turbo is at +0.078V like in video and offset is -0.015V. This is a very stable setting, I ran prime95 19 hours without problems and intel burn test 20 times on maximum, but voltage goes up to 1.388 in ibt and temps up to 90C. Lowest idle voltage is around 0.980 according to AXTU.
Maziz56 My Vcore with these is 0.976 idle and 1.336-1.344 full load. I am not a fan of IBT since it produces ridiculously high temperatures compared to Prime 95. If you want to bring your Vcore down, you can try decreasing your offset first since your idle is low but could possibly go lower and still remain stable. You may be able to decrease offset by maybe another 20mv +/- (0.020). If you are happy with where your idle vcore is at, then only decrease Additional Turbo voltage. Additional Turbo Voltage will only Increase/Decrease your full load Vcore so your idle will remain the same at 0.980.
Maximum Vcore I lowered turbo voltage by 0.010 and it's perfectly stable. Lowering by 0.020 made it a bit unstable so I guess my chip just isn't that good. :p But thanks again you helped a lot!
it still says 98-99.something when i have disabled spectrum. is 0.010 really enough voltage? i dont have levels on my calibration i have 0-100% whats the difference?
Do you have a Z68/Z77 Pro? If so then it may be the board since they are more limited compared to an Extreme/Fatality series. 0.010? It depends on what CPU you have, what multiplier, and what vcore is displayed in CPU-z during idle and full load. It will be different for every cpu.
hi, i followed your instructions exactly as displayed on screen - but my CPU never goes above 3,7GHz for some reason (even under stress test). I have i5 2500k on a z68 extreme4 gen3 with bios rev 2.30
Hi! I have Asrock z77 Extreme4 and I noticed that you're using 4 rams. Mine is not working, I'm using 4x Kingston 4gb, 1600mhz, kvr16n11s8/4. But only A2,B2 are being detected. Help please 😭😭😭
I had blue screen on idle, increase only offset from what I understand right? additional voltage turbo only happen if I change blue screen at full load Sorry, my english not good
+Edson Correct, If you BSOD or have any type of crashes at idle then increase your offset. This happens because your Idle Vcore is too low. Only increase Additional Turbo Voltage to stabilize at full load. :)
Edson Go to where Cpu-z is installed. Open the configuration file and change bus speed from 1 to 0. Save the file. (I had to save it to desktop and the copy paste /replace for it to work. Then you will see 100 =)
Please help me understand: you undervolted the CPU at idle using offset voltage -0.010V and overvolted it at 4.6Ghz with additional turbo voltage? What`s your exact voltage @4.6 Ghz? Thx!
Hellos Cosmin, Offset will provide both an idle and full load vcore. Additional Turbo Voltage is "in addition to" the full load vcore that is provided by your current offset. Additional turbo voltage allows you to increase the full load vcore without increasing the idle vcore. I decreased my idle vcore to where i wanted it using negative offset (which also decreased my full load vcore). Then stabilized my full load vcore by increasing additional turbo voltage. My idle vcore was 0.976v and full load vcore was 1.336v -1.344v.
i have 2500k and p67 pro3 i put 4,0 ghz, offset -0.125 load calibration level 3 and i cant start the system!! ive got black screen, the coolers on GPU are on 100%, hell.. pls help me! ;-(
Hm, looks like I get it to work now... i've changed the vcore to Fixed Mode with 1,37V, cpu ratio to 45 (100x45) and i've got 4,5GHZ with 1,37V max 60C, not bad, but voltage could be better... bad chip :/
+Marek W Well the CPU vcore is not going to decrease at idle when using fixed. Keep playing with Offset and Turbo for a more efficient OC. I would guess the board more than the chip since its a Pro 3
Well, how does this work with asrock z68gen3pro bios 2.3?. I have i5 2500K and thermalright hr-2 macho, and want to boost up my bottleneck 3,3GHz. I gotta admit, that I dont have any clue what options to change in newer bios version. I've tried some sets, but with bad results (throttling, unstable etc.). Would appreciate If you could help me to get 4,4-4,5 stable without pumping volts to heat cpu up too much.
The 2.3 BIOS version on the pro should be similar if not identical to my BIOS in the video. Majority of the settings will be the same except Multiplier, Offset, and Additional Turbo voltage. These three settings will vary based on multiple variables so you will need to do a little trial and error to when attempting to stabilize. The main limitation with the Z68 Pro 3 is that it has 4 + 2 phase VRM's so it may not achieve as high of Overclocks as other boards. What offset / turbo are you using for a 44 or 45 multi? What is the idle and full load vcore with those settings ? What temps?
on the CPU Ratio, I can only overclock on the All Core to number 39. Any number higher than that will automatically go to 39. But any number less will stay at that number. Any tips on how to fix that?
Not sure what board you have but maybe reset BIOS/UEFI or Maybe your board has a bug needs to be flashed to newer BIOS. I would check message boards for similar topics
It depends but if your temps are too high then you probably want to decrease the multiplier by 1 along with decreasing turbo voltage. What is your idle and full load vcore? What is your offset and turbo settings?
+filp69 These setting are for my CPU so they may vary for others. This is why you have to stress test the CPU to find the correct Offset and Turbo. The -0.010v offset places my CPU's idle Vcore at 0.976v where at stock, my CPU idles around 0.960v. Don't think that negative offset is bad or is under powering the CPU just because its set to negative. Negative and Positive offset is just a way to adjust your voltage. Depending on the Vcore your CPU requires and the multiplier, the offset and turbo will be different. This is why you will need to check your idle and full load vcore in CPU-z and adjust your offset and turbo accordingly so that you not undervolting at idle or overvolting at full load for that specific multiplier.
this is kind of a late question, but my vcore is about 1.375 with prime95 using this exact same config. what would you recomend to change? reducing the turbo voltage? im using 2600k in a extreme3 z77 board
My offset is 0.05, my idle vcore is 0.995 and my turbo right now is 0.060, i changed it recently and now i got a vcore of 1.360~1.365, but my clock is at 4.4 instead of 4.5
+Kanavi Hakurei You can try reducing offset to -0.010 or -0.015 to decrease both Idle and full load. After that you can start bringing down turbo to reduce full load only. You should be able to stabilize 44 around 1.30v +/-
Richard Sheriff Yes, the BIOS (If updated) is pretty much identical for all Asrock Z68 and Z77 motherboards so all settings will be the same. You will only need to adjust Multi, Offset, & Turbo.
Maximum Vcore no, I have the latest bios version. I have like you the number of cpu multiplier in light blue but it is impossible to change. Can you make another video guide but step by step from default bios setting to overclocked?
Z77 doesnt work to get it stable on 4,5 with this.. CPU 2500K.. for me i cant seem to get higher than 4.2 without blue screening while intel burntesting

Great video guide. thanks s lot.
Can you please explain why you set the additional turbo voltage to 0.078?
Thank you. Additional turbo voltage only increases your full load vcore. Offset will increase both your idle and full load vcore. By using both together you can have your CPU idle at a Vcore that is similar or lower then stock and still be able to stabilize your full load vcore. If you use offset by itself (Additional Turbo Voltage on Auto) you will not have any control over you idle vcore. I will try and get another video up soon :)
Raian Senpai
Offset controls both the Idle and full load vcore. Turbo will add additional voltage to the full load vcore that you get from the offset. What multiplier are you shooting for? What is your offset set to and what is your current idle vcore in CPU-z?
I have a i5-3570k base speed @3.4 I followed the video and everything went to bios changed everything like u did in the video and save the file and loaded it well I started my computer up and it’s still at 3.4ghz @maximum Vcore
Not sure. Maybe the OC didn't stick. Check BIOS settings again and maybe try applying a lower multiplier.
C1E enabled makes my AsRock Z68m freeze randomly. When OCig, Id double check its off.
The sticker on my ram says XMP ready but it doesn't show up in bios like yours did.
Thanks for the video. It was really helpful! I have one question, if you have time. Most people on here are talking about their vcore being a bit high, but mine is a bit lower and I'm wondering if there's any downside to that?

Everything seems stable after about an hour of prime95.
Should I try to get my vcore closer to 1.35? Or is it fine where it is?
Thanks again!
+OriginalMooMix
That's fine, offset and turbo settings will produce a different Vcore for each CPU since the VID is different between each CPU.

I know it has been a long time, but I still have an i7 3770 (non K). Built it with an old AsRock z77 Pro3. Trying to OC it. My settings are: 42 multiplyer; BCLK 100.0; Additional Volt. +0.055V; Limits: 300-300-250-250; No Offset. When on CPU-Z, it doesn't reach 4.2 Ghz, but 4.1(ish). Stressed, did some tests... rock solid (so far). My cooler is a very good air cooling system (65 degrees C when stressed). I'm trying to reach 4.2 Ghz, but no further. What did I do wrong?
Looks like 4.1ghz is max oc for Non K. You can probably enter a higher multiplier in bios but the CPU wont go above 4.1.
@@Lucky223 Before that I OCd it to 4.2, but messing with the BCLK. I just saw a video someone OCing the 3770 (non K) to 4.3 Ghz, without messing with de MoBo BUS. Gonna make more tests. If it's possible, I'm gonna try to reach 4.5 Ghz.
I don't quite understand additional turbo voltage. Will you be expanding on it?
Thanks for the video.
SKazclaw
Hello SKazclaw ,
Offset will produce an idle and full load Vcore. It will also Increase/Decrease your Idle and Full load Vcore depending on what it is set to.
Example 1: A +0.005 offset will have a higher idle and full load Vcore then a -0.005 Offset.
Additional Turbo Voltage will only increase your full load Vcore and does NOT affect Idle Vcore. Its basically an "In Addition To" the full load Vcore provided by Offset.
How Offset works: Example 2
Lets say you have Offset set to +0.005 (Turbo on Auto and say Auto = 0.000v). CPU-z displays idle Vcore at 0.96v and Full load at 1.350v during Prime 95.
How Additional Turbo Voltage Works:
Now lets say you change Additional Turbo Voltage from Auto (0.000v) to +0.004v and leave your Offset at +0.005. Now your Full Load Vcore during Prime 95 will be 1.354v.
This is how Offset and Additional Turbo Voltage works but I am also simplifying it and not accounting for Vdroop to make it easier to understand.
Does this make sense? :)
Maximum Vcore
Thank you for the detailed response Vcore. I have my system OCed to your settings currently.
With your help now, and with some research I did last night, I am going to give it a shot OCing it myself.
Any idea why my z68 pro 3-m doesn't want to go over a ratio for all core about 37? I have a 2500k inside and as far as I can tell both the CPU and the Mobo should be able to overclock. Whatever i fill in over the value of basically 3700mhz, will just default back to a max of 3700mhz.
Running an ASRock Z77 EXT. 4 w/2600k this board will not let me enter a multiplier of x38. Seen lots of folks with this issue but no solution. Old MB ASUS P8P67 LE and i could get over 5 Ghz out this beast on an H70 in push-pull. As is I sacraficed a PCI-E lane for my 1060 6Gb. If someone knows then hit me up please.
update your bios
Hi yes I know this is old but is there a reason why I had to increase my offset voltage mine would not Overclock until I changed to +.010
He got luckier with his silicon
The offset voltage controls your idle and full load Vcore. Additional turbo voltage is additional mv added to the full load vcore produced by the offset. You most likely had to increase offset because your OC was unstable. Possible the idle vcore was also too low.
Thank you for your video. I did exactly what you did. However, the CPU-Z is showing *16 (16-46) and *46 (16-46) alternatively. Did I successfully overlock my i5-3570k to 4.6 ghz?
My pc won't boot with this config, what did I do wrong?
I applied these settings on my 3570K and my system will no longer boot. Just goes to bios page and restarts
You need to increase the offset voltage

Do you think I can tweak it up to 4.0 and keep it running at that speed using the same method?
(its max boost technology pushes it up to 3.9 and I think at this speed I gave the results above).

Hello,
What is your offset and turbo set to?
Hello, thanks for answering. Exactly the same you set at the video.
Acupuntura Fabio Athayde Curitiba
Ok, well the Offset and Turbo will be different for all CPU's and multipliers. I am not sure what multiplier you have but if you want to reduce your your full load vcore then you will need to reduce the additional turbo voltage. An idle Vcore of 1.1v is still a little high so you can also try for a higher negative offset such as -0.015, -0.020 ect. Changing the offset will will affect both your idle and full load vcore even if no changes are made to Additional turbo voltage.
Very great guide man thank you, but could you make a new video about Additional Turbo Voltage @ 3:15 in the video :)
best regards
I'm sorry, Ive been meaning to make another but have been busy. I'll do my best to get another video made for Offset & Additional Turbo Voltage. If you have any questions, you can post them here :)

That is because you have a Pro board so the BIOS is slightly different than an Extreme series.

Se puede hacer OC al i5 3570K aún usandolo con la integrada? osea oc al procesador solo sin necesidad de tener placa de video aparte, gracias
sisi se puede. el overclock de la placa de video se configura desde la bios pero es aparte. todo tambien depende de la refrigeracion que le pongas al procesador.
I have the exact same hardware as you aside from the ram I'm using which is 1333 PNY but I don't seem to have a XMP option above the ram frequency. Should I just leave it on auto and not worry or am I missing something.
XMP is only for the stock speed of the RAM. If you select the XMP profile, it will set you speed (1333), timings and voltage, so you really don't need to touch any of these settings. If overclocking your RAM then you will need to set it up manually without XMP. You should see other frequencies listed under DRAM frequency.
It zeems I can not go for 4.6. Only at 4.2 in time it crashes
Why does my corespeed not stable at 4689? it goes back to 1599 and sometimes goes to 3k+ .. and btw, my windows in system properties wont show that i overclocked it to 4.6, i am using cpuid and i am on i7 2600k.. and i dont have any problems on 4.6 OC , no blue screen or crash but just on Corespeed i saw it goes up & down. Thanks

Look at my reply to kathness24. If you are not stable at 4.7ghz during Prime 95 then you will need to increase the Additional Turbo Voltage.

Hi! Thanks for video! I did exactly what you asked for , but temperatures reached 85 degrees (24 hours in Prime95 - Blend ) . Is there anything I can do to reduce them ? I have a Z68 Fatalyt1 Pro + Seidon 120M + i7 3770k@46
Celso Junior
Hello Celso,
85c during Prime95 blend is not bad at all especially since the 3770K throttles at 98c. Also the temperatures you reach during Prime 95 are no where near the every day load temperatures of the CPU. Your gaming temperatures will probably be around 65c +/-. Honestly if Prime 95 passed a 24 hours blend test w/out a worker failing or any whea errors then your OC is stable.
If you would still like to reduce your full load temperatures then you will either have to upgrade you CPU cooling or reduce you OC to 4.4-4.5ghz and decrease your Vcore.

Hi what is the model of the motherboard you used on this vídeo? My cooler 212 will be god to oc my i5 2500k? Thank you
FunkyBallcat
Hello FunkyBallcat,
It is an Asrock Extreme 3 Gen 3 (2.30 Bios) w/ a 2500k CPU. Yes a EVO will be good for overclocking your CPU, probably up to 1.30v to 1.35 Vcore.
Hey I'm new to this. How do I know if my offset is positive or negative? I only knew fixed voltages before.
The starting point for is always +0.005 offset / +0.004 turbo. If the system boots into windows, open CPU-z and see what the vcore is when the CPU is at a 16 multiplier. This will be your idle vcore. Then start up a stress test for a minute to get a estimate of your full load vcore. Idle vcore should usually be ~.90v to 1.00v. If your idle is higher then this, then go negative offset until its in this range. Last, increase your full load vcore with additional turbo voltage until your OC is stable during stress test.
why is asrocks so complex my old msi board was so good you set the voltage to what you want and the multiplier and your done never had a problem with it.
Well, you can still do that on this board. That is called a fixed OC but that is not what I'm showing in the video. The video is showing how to setup Offset / Turbo so that your OC (multiplier and voltage) will scale depending on the load. I guess compared to fixed, yes its a little bit more complicated.
Maximum Vcore I tried a fixed overclock but the voltages were never what I put in I know the voltage my cpu takes for a 4.5 ghz overclock but when I do that with the asrock board the voltages were all over the place and the system was very unstable the msi board I used a fixes voltage and I put in 1.345v and that is what I got asrock board you need to play with that load line calibration but no matter what I set it at it still did not give me the right voltage and even spiked to voltages I do not deem safe for the cpu. my msi board was an expansive board designed for overclocking and it did a fucking amazing job it make me cry every time lel. I have got my overclock working tho now just to let you know but fuck it was a job and a half to get it. and your video was very helpful
Nice thanks. What is your vcore with these settings? I have z68 pro 3 + i5-2500k and with these settings vcore goes up to 1.380. Temps max at 75 with prime95 so this doesnt' seem bad. I'll see if this is stable for me and maybe start dropping additional turbo voltage 0.005 at a time, or should I drop offset voltage?
Maziz56
Depends, What is the offset and Turbo set to ? What is your Idle Vcore?
Maximum Vcore
Turbo is at +0.078V like in video and offset is -0.015V. This is a very stable setting, I ran prime95 19 hours without problems and intel burn test 20 times on maximum, but voltage goes up to 1.388 in ibt and temps up to 90C. Lowest idle voltage is around 0.980 according to AXTU.
Maziz56
My Vcore with these is 0.976 idle and 1.336-1.344 full load. I am not a fan of IBT since it produces ridiculously high temperatures compared to Prime 95.
If you want to bring your Vcore down, you can try decreasing your offset first since your idle is low but could possibly go lower and still remain stable. You may be able to decrease offset by maybe another 20mv +/- (0.020).
If you are happy with where your idle vcore is at, then only decrease Additional Turbo voltage. Additional Turbo Voltage will only Increase/Decrease your full load Vcore so your idle will remain the same at 0.980.
Maximum Vcore
I lowered turbo voltage by 0.010 and it's perfectly stable. Lowering by 0.020 made it a bit unstable so I guess my chip just isn't that good. :p But thanks again you helped a lot!
Works really good but i can only get to multiplayer 42 and it crashes above it what should i do?
I have asrock z77 pro3 and i5 3570k
same
it still says 98-99.something when i have disabled spectrum. is 0.010 really enough voltage? i dont have levels on my calibration i have 0-100% whats the difference?
Do you have a Z68/Z77 Pro? If so then it may be the board since they are more limited compared to an Extreme/Fatality series.
0.010? It depends on what CPU you have, what multiplier, and what vcore is displayed in CPU-z during idle and full load. It will be different for every cpu.
Hello thanks before its worked for me i got 4.5 for i5-3570k ofset voltage -0.010 V but temp full load 74.c , what i going do for lower temp ?
Better CPU cooling or less Vcore (lower overclock)

Correct, If you BSOD or have any type of crashes at idle then increase your offset. This happens because your Idle Vcore is too low.
Only increase Additional Turbo Voltage to stabilize at full load. :)

Please help me understand: you undervolted the CPU at idle using offset voltage -0.010V and overvolted it at 4.6Ghz with additional turbo voltage? What`s your exact voltage @4.6 Ghz? Thx!
Hellos Cosmin, Offset will provide both an idle and full load vcore. Additional Turbo Voltage is "in addition to" the full load vcore that is provided by your current offset. Additional turbo voltage allows you to increase the full load vcore without increasing the idle vcore.
I decreased my idle vcore to where i wanted it using negative offset (which also decreased my full load vcore). Then stabilized my full load vcore by increasing additional turbo voltage.
My idle vcore was 0.976v and full load vcore was 1.336v -1.344v.

+Marek W
Well the CPU vcore is not going to decrease at idle when using fixed. Keep playing with Offset and Turbo for a more efficient OC. I would guess the board more than the chip since its a Pro 3
Well, how does this work with asrock z68gen3pro bios 2.3?. I have i5 2500K and thermalright hr-2 macho, and want to boost up my bottleneck 3,3GHz. I gotta admit, that I dont have any clue what options to change in newer bios version. I've tried some sets, but with bad results (throttling, unstable etc.). Would appreciate If you could help me to get 4,4-4,5 stable without pumping volts to heat cpu up too much.
The 2.3 BIOS version on the pro should be similar if not identical to my BIOS in the video. Majority of the settings will be the same except Multiplier, Offset, and Additional Turbo voltage. These three settings will vary based on multiple variables so you will need to do a little trial and error to when attempting to stabilize. The main limitation with the Z68 Pro 3 is that it has 4 + 2 phase VRM's so it may not achieve as high of Overclocks as other boards.
What offset / turbo are you using for a 44 or 45 multi? What is the idle and full load vcore with those settings ? What temps?
can you go to 4.5 directly from 3.3 ? or you need to do step by step like 3.3, 3,4 3,5....ect ? thanks !
okay thanks !
on the CPU Ratio, I can only overclock on the All Core to number 39. Any number higher than that will automatically go to 39. But any number less will stay at that number. Any tips on how to fix that?
Not sure what board you have but maybe reset BIOS/UEFI or Maybe your board has a bug needs to be flashed to newer BIOS. I would check message boards for similar topics

Is this Only For Z77? Or ASRock B75M can oc too
on ur offset voltage u set it to -0.010v? will a underpowered cpu perform well?
+filp69
These setting are for my CPU so they may vary for others. This is why you have to stress test the CPU to find the correct Offset and Turbo.
The -0.010v offset places my CPU's idle Vcore at 0.976v where at stock, my CPU idles around 0.960v. Don't think that negative offset is bad or is under powering the CPU just because its set to negative. Negative and Positive offset is just a way to adjust your voltage. Depending on the Vcore your CPU requires and the multiplier, the offset and turbo will be different.
This is why you will need to check your idle and full load vcore in CPU-z and adjust your offset and turbo accordingly so that you not undervolting at idle or overvolting at full load for that specific multiplier.
Which bios do you use. I have p2.30. Every time I set the multiplier from 33 to 46, it reverts back to 37...weird. Sandybridge 2500k too btw
Yes, I had P2.30 on this board. Not sure why the multiplier is reverting back to stock. Maybe Load defaults and start again.
I tried that already. Problem remains. I changed my memory recently, so maybe it's that.
this is kind of a late question, but my vcore is about 1.375 with prime95 using this exact same config.
what would you recomend to change? reducing the turbo voltage?

+Kanavi Hakurei
You can try reducing offset to -0.010 or -0.015 to decrease both Idle and full load. After that you can start bringing down turbo to reduce full load only. You should be able to stabilize 44 around 1.30v +/-
Hey dude ,
I have a asrock z77 gaming performance board with a i5 3570k will this be ok other than the offset features :) 👍

Yes, the BIOS (If updated) is pretty much identical for all Asrock Z68 and Z77 motherboards so all settings will be the same. You will only need to adjust Multi, Offset, & Turbo.
