Your explanation of curve optimizer in your video from 3 weeks ago was a lifesaver. Thank you so much. I was able to push my 9950x to -24/-26 (CCX0/1) netting 5.4% cinebench performance without raising the power limits or temps. I'm currently 24 hours into a stability test with aida64 and working on a prime95 stability test to validate it's stable. If you have any advice on stability testing it would be appreciated! side note: idk why but applying overclock/co settings in ryzen master on my asus x670 creator mobo would cause my pc to not boot until I cleared the CMOS. I assume it's a bug but I had to use the bios for all the tweeking.
Thanks for the kind words. I'm happy my video helped! As for CO testing: don't forget to mix workloads when testing. A common error is to test CO only with stress test tools. Those tools tend to run high temperature and moderate frequency. But sometimes CO is unstable at medium temperature and high frequency, or high frequency and high temperature. I found that looping the Y-Cruncher component stress tester can sometimes also uncover CO instabilities.
I run AIDA FPU/Memory/Cache stress test to detect unstable CO. On settings that Cinebench runs for infinite amount of time without any problems, this test crashes my PC in 5-10 seconds. I needed to lower CO by 15 points to make this test run for some extended amount of time.
Thanks for the info. How does that compare to the VFT curve of 7000 series? Is it the same or better? Although I'm not sure we can draw conclusions from just one sample.
You are right: it's difficult to draw conclusions from just one sample. Also, I am using a new methodology for putting together the Ryzen 9000 V/F curves. So it might not be comparable to my Ryzen 7000 results.
Subscribed, I know I don't fully understand everything you are showing me, but I have a 9950X being delivered tomorrow and I will be using your vids to have a play
I haven't tried it myself but before launch I was told it's a Zen 5 exclusive. However, seems the option is available for Zen 4 on some motherboards and it works too. So, I think it does work with Ryzen 7000.
Lol... It does show though that if you did use the most optimal water cooling setup such as direct die that it should definitely improve performance with the amount of voltage that is used which will lower temperatures which will allow higher frequency.
@@JMNovak1011i have 5800x 3d that with kombo buster on my msi board the cpu doesn't seem to care about voltage or temps too much. I top out ar 90c, but scored closed to 2,450 in cinebench. Lowering voltage drop 8c to 82c but scroes only 2,325. Think my chip might be golden for LN2 overclocking.
@@kevinerbs2778 yeah it's a very unique give and take between voltage temperature and frequency. There's also quality of the cores which comes into play. We've seen that in a lot of different Zen cores now where one person can hit a certain frequency at a certain voltage and someone else will be 100-200 megahertz under that at the same voltage. I mean you also see it with how CCD 0 usually has the highest binned cores and CCD 1 has lower performing cores because AMD loves to get rid of their trash CCDs by just sticking them on the dual CCD chips
Peltiers are low capacity and grossly inefficient. Probably better to start with an AIO, then duct a window unit air conditioner around the PC, and modify its compressor for variable speed (or start with a model that has that feature). Dry air, no temperature differentials, and you get the extra-low-temperature benefits for RAM and GPU too.
recently upgraded my Asus x670e Gene bios with my 7800x3D on it and noticed there is now a "Curve Shaper" option. Thought this was Zen 5 exclusive? Any thoughts? Would this help with e-clk overclocking?
I thought so too but apparently it also works on Zen 4. It should help with ECLK. I explored that at length in my 9700X guide. You can check that one for reference how Curve Shaper helps with ECLK strategies.
I can't believe that amd wouldn't have just done this work for us. Why would they leave this much performance on the table for just a few willing to tinker with it? I'm still on zen 3 and stable using a flat .2v under volt. Are they just outsourcing their r and d to enthusiasts?
This channel is too underrated
because he have stupid themes about floop cpus which nobody wants
True lessons here... GG
Commenting because you're awesome
Upvoting you because you are awesome !
Amazing content! Keep it up!
Does lower temps = higher boost with lover voltages also apply to 7000-8000 ryzen?
Yes, this has been on Ryzen CPUs for many generations.

I too experienced the same problem with ryzen master on my msi board, had to clear bios.
Awesome video!
i love this video. just love it.
Great video, thank you!

Absolute legend!

Did you mean to have "Granite Ridge" on those slides?
Yes. Did I get some slides wrong?
@@SkatterBencher For some reason I thought that was Intel.
That would be Granite Rapids ... It's been confusing me too haha!
You don't think 1.3volt it's too much ??
When I did -30 negative windows froze, I had to reboot my computer, I guess trying with -20 first and then increment little by little
Do you think Curve Shaper can work with Ryzen 7000 CPUs? It seems like it's more of a software feature than a hardware one.

I’m on a black screen whenever I try to boot up my computer how do I get back to bios
👍
So you basically need direct die cooler, with peltierelement and liquid metal at ~20°C all the time... noted
Lol... It does show though that if you did use the most optimal water cooling setup such as direct die that it should definitely improve performance with the amount of voltage that is used which will lower temperatures which will allow higher frequency.

This is nightmare to test stability, but can be useful in gaming.

C'mon YT algorithm, do your thing, i promise it's worth it.
