- It is time to relive some of the experiences I had with PCs as a teenager.
The Intel Pentium MMX was the first CPU I ever overclocked!
So here I am 20 years later with an overclock of the Tillamook to 420MHz.

Great video! Thanks for your interesting work and sharing this with us. ☺️
Came to the comments looking for you. Was not let down.
I was actually expecting the Pentium MMX WIPE THE FLOOR in Quake. Guess Not then. Savesme alot of headche. :D
@@AmstradExin It would with a period correct 3D card. A Geforce offloads the CPU way too much in 3D apps to make relevant benchs. I'll soon compare with the opposite of a GF :D : the PowerVR PCX1.
Super awesome video! Cpu Galaxy brought me here!
Thnx! :)
Funny thing...
The first video I watched from Cpu Galaxy was also about Tillamook.
had a K6II 400 running at 550Mhz back in the day.. and a K6 III+ running at 600Mhz Fun times
I bought a K6-2 500, but couldn’t get it to overclock. It was still incredibly fast for what I paid.
I somehow missed this video in the past. I was currently searching some infos about the Tillamook (for my VRM project) and stumbled upon this video :D Very interesting results, thank you very much as always!
only 1 mega byte level 2 cache that is an outrage it should atleast be 2 or 4 megabyte of level 2 cache at least💪✊💀
Done watching - very nice! The PMMX was a nice cpu and closely tied to really enjoying Quake and QuakeII for me.
great oc, thanks! Had the same chip back in the day. it was soo good to remember. =) thx
Love your work :)
Thank you for your tests. I had a MM 166 overclocked to 233 on my SS7 board. Good times :)
wow that's some hardcore retro-overclock, really interesting!
More is coming soon :)
Thank you, random yet interesting!
Pentium mmx233 overclocked to 300. Same youth here :)
Holy hell, man, I have that EXACT SAME BOARD!
The 512KB cache model assume :p
I had one back then, but lost it in a move. I wish I still had it!
My first MMX chip was a Cyrix 686 chip. Not the best but it served me well. Enjoyed the video!
I have everything from Cyrix too. This is the next thing I will test and make a video about with this M/B.
@@atheatos Great! I'll look forward to the video!
I had a PMMX 200@225 with 75mhz bus that can't run Unreal Tournament well. I replaced with a K6-2 475@450, it was overvolted because the MB didn't support lower voltage, and then it can run UT well with a voodoo2. With the PMMX the CPU was the bottleneck. Great video!
Yea, P MMX is not good enough for UT. UT is very demanding.
My set-up is an overkill, so UT is probably playable at low resolutions.
Then again, for SS7 the best inexpensive option is probably the k6-2+ (if supported by the M/B).
I had a K6-2 500 with an overclocked Voodoo2. It was fantastic in UT and Q3A.
Unreal was very CPU heavy. You needed somewhere around 400 MHz pentium II /K6-2+ 550 MHz to max it out at 800x600 resolution with a voodoo 2. At 640x480 you had to have an athlon or PIII in the 700 MHz-ish range before you no longer saw any framerate gains.
That's really, really CPU heavy. GLQuake needed only a P166 MMX before you were close to maxing out a voodoo 2 at 800x600 on a voodoo 2.
Great video crazy the mobile Pentium 266mmx can be clocked so much(Granted with the right MB)but that low of a voltage lets you push that cpu to its max. I as well saw this video because of CPU Galaxy. Thanks for the video.
Thanx! I have more CPUs to check and videos to make with This SS7 M/Bs.
Awesome stuff! When it comes to the K6 CPUs I remember seeing a K6-2+ cpu(granted its the 100FSB version) laptop version but still SS7 version and running at 1.6 volts instead of running at 2.0 volts running at 400Mhz and could be over clocked to 600Mhz at 2.1 or 2.2 volts due to it being such low voltage it gave headroom to overclock so much. Again great video yes to more cpu tests with this board or other combos as well.
Thank you :)
I have a lot of SS7 M/Bs too. I come to them at some point.
I have already done the K6-2, K6-2+ and K6-III+ with the Video review of this Asus P5A MB.

Sounds like your PC upbringing was very similar to my own, I used to watch my dad building up 386 and 486 machines which fascinated me and set me up nicely to really understand them in the Pentium era, always built my own machines just based on what I learned watching him.
That Soyo SS7 motherboard is a great transitional piece, it seems to bridge the era-dividing line in 90s hardware nicely with it's mix of ISA, PCI, SIMM and DIMM slots as well as supporting AT and ATX power connectors! very cool. Also interesting to me are your Quake benchmark results, the much more demanding and later Quake 3 Arena performing significantly better than either machine running the relatively simple Quake 1, would not have expected that and to be honest the Quake numbers seem impossibly low for either configuration - was something wrong there? Almost looks like vsync was on or something.
The 90s and early 00s Soyo boards were rock solid - great choice
I loved my Soyo boards back then! My first 2 builds / overclocks had one.
Great Video. Thanks for the information how to modify the cpu. My tillamook is now working with 450mhz and 3dfx voodoo 3 3000
wow 450MHz very nice! I have a few of these, most do not go above easily. My best is this on the video.
@atheatos I got the freqency with FSB 110 (interpreted as 112) * 4 on my Asus P5A with 512kb Cache. V-Core is 2,4V. Test with 2.2V currently not tested but comming soon. More Power is not possible. My pci latency timer is working with 128. That is the only the different to your P5A.
128MB PC133 CL2, Voodoo3 3000 @180,
A short sumery of my CPU performens.
3DMark 99 CPU: 2927
PCMark2002: 773
Very nice!
Awesome. I have one of these cpu's so will have to do the mods and see if I can get it working. No post on my Epox EP-MVP3G5
I have two variations of this board. I just did a quick test and it works fine with the mods. (With 3 out of 4 of the mods).
@@atheatos Thanks for that. I'll give it a go.
Also, 420MHz. Time to blaze those Win95 and DOS benchmarks.
Pentium MMX and GF4 Ti 4600, probably the most overkill combination I've ever seen. :D
Sure it is an overkill.
Usually my focus is in comparing M/Bs or CPUs so for the VGAs I go overkill.
I am not building Retro PCs to actually use them. I have a huge collection.
Very interesting. What version of SuperPi do you use?
I think I used the last available for windows 98.
Then, I just checked... it is Ver. 1.1
No optimizations or anything special for SuperPi.
It is possible to increase your score by doing some stuff before running it.
thank you for the video, I've asked on retro groups for this video as I'm not confident with my soldering. I'd thought the stronger FPU would make intel a bit better than amd in Q3 at 400mhz+
Even if you are not that good with soldering... this mod is relatively easy. Just get the right tools as described in the video and make this carefully. Maybe I should sell these already modded in the store. Well in general K6-2 is always better as it can also clock higher.
@@atheatosTillamook is no longer for sale on ebay anyway, they should come at a premium. I saved the seller on my account, but he's not selling the CPUs anymore. Haven't tried aliexpress or anything like that.
wow, I just checked. Things have changed a lot! Thank you for the info.
I have 4 of these all modded. I should have stocked more of these :/
I will put some in the store soon.
i am going to attempt this on a pentium 1 MMX 166 mhz from a Tullip laptop. any tips/documentation on any other pin short combinations for other clocks? i did this to a pentium 4 desktop cpu to raise voltage's so fsb can be increased on a gericom laptop
I do not have something more. Check also the vogons link in the description. Maybe not all the information here is applicable to your CPU, but you can try. ^^
very nice OC on that CPU, The Pentiums was good overclockers
Yeah even the original MMX can all overclock to 266+.
I had 166 to 3 x 100 = 300 back in the day :)
@@atheatos impressive stuff. My first personal own computer was a pentium. I overclocked it to 166mhz and used it like that for ages. As of later I found out it would do 200 no problem but back in the days when this was my first own computer I was afraid it would damage the cpu. But also mad at myself it could have done so much more if I just dared lol
Yeah a bit sad.
For me this was the 3rd PC. The first was a 386.
But this was first one I was old enough to tweak / built.
I did not go directly to 300. This was a fun step by step prosses :)
@@atheatos our first computer was a 33mhz 486. I began upgrading this computer with a better cpu and ram. And I think I began with an extra hard drive. I did not know they needed to be slave/master then and I got this hard drive from a flea market. I put that in and there was Linux on the drive. Somehow the computer could boot with two master drives on the same cable. Linux won the battle and annihilated the windows data. I was yelled at and at this point I swear I would never be yelled at for bad computer knowledge again. I started to learn everything hardware based in computers to outshine everyone I knew with this and succeeded. I been building my own and others computers ever since and even troubleshooting and repairing. Even at the company I work with today I am responsive to maintain the whole computer network lol.
But I been overclocking my computers ever since I began. And I won’t stop doing it ha ha
Nice story :)
I also overclocked every thing since then :)
Had a few celerons and PIII after that
Had a K6-2-350 as my first ever 'real' gaming PC. Got it working over summer vacation. Got that thing to 495MHz but It just didn't want to give up that last 5MHz.
XD
Actually... back then this P MXX was finally upgraded to a very inexpensive K6-2 300.
These early K6-2s can not pass 350 - 400Mhz :(
Still it was a good upgrade.
I had the K6-2 350 as my first real gaming machine, too! It hit 400 easily.
I have a dual P233MMX workstation board running the CPUs at stock speeds, and thinking if its possible to take it up to 300-400MHz,
but first I need to do a recap as it is from 1996-97 and don't want to push it with the old capacitors.
That is also a nice find :)
I do not have something like that.
Normal Pmmx do not go higher than 300Mhz.
Also these M/Bs at best will have a setting for 83Mhz bus, so 3.5 x 83 = 291MHz.
For best results use Electrolytic Polymer capacitors.
I was more modest with my overclocks than some of you back then - I had a 100MHZ Pentium overclocked to 120MHZ because I didn't want to risk my daily driver. Made up for it later when I got a Celeron 300A up to 450MHz.
I used to have a Celeron 667Mhz that would easily do 1050Mhz without breaking a sweat. Was quite common back in the day
I have a PMMX 200@225 with 75mhz bus, was faster than a 233 OC with 66mhz bus.
Nice, try going higher :)
Nearly all Pentium MMX can do 270-280 some go to 300.
@@atheatos I mean had, not have, sorry. It can't run at 250 with stock voltage, it was all ceramic package.
I see, you are right.
The best pentium mmx.i like it
😲😲😲 I have a nice p133mmx 😁
I had cyrix 2 200mhz overlocked to 233mhz. Great times
I have nearly everything from Cyrix too. I might do a video.
Isn't K6-2 faster in SuperPI with lower time for calculation and not the other way around?
On the table, the SuperPI value is not time, it is a score calculated as 100K/time(sec).
So everything in the table is higher better. I explained this on my ASUS P5A video.
What cooling solution did you use for the pentium?
These do not heat that much.
Up to 400Mhz you can go with just a good air cooler like the stock PIII S370.
Now for 420Mhz, things are hard. I used some pettier+ tower cooler combo.
I have seen people doing 450Mhz at higher voltages, but I think he only had DOS tests.
@@atheatos would a more modern cooler fit? Sat something like an AMD cooler? Those mostly fit am1 to AM4 is it's the clip type and not screwed to the motherboard type.
In general NO.
You need a cooler with a clip.
Socket 7 and Socket 370 coolers are ok.
Socket A coolers... the clip is ok but these are usually wider... so sometimes they collide with components on the M/B.
Later AMD coolers are not compatible, the clip is longer.
I general cooling is not that critical, but Yes you need an old one.
@@atheatos I figured the clip would be different on the and ones but maybe there is a way to use a different clip
Maybe, with some of them you can replace the clip.
Either-way SS7 does not need that much cooling in general.
Getting 454MHz out of my Celeron 300A was a great time. I felt sorry for the people who bought "real" Pentium II 450MHz CPUs.
Yea that was a very nice period!
Wow. I thought I was the man for clocking a 233mhz Tillamook to 300mhz stable.
Impressive.
Thnx, most (no all) normal Pentium MMX can do 300MHz. and most Tillamook 400MHz. Always with a good M/B and increased vcore.
@@atheatos I definitely increased vcore a little, the mobo I was using was trash though. Would like to revisit this one day with watercooling and a temp sensor under the core.
Thanks for the reply! Tale care brother.
Also try recap your motherboard.
Why you just not take a celeron 400 or 433 at 66 fsb
I have all-ready maybe 10 of these celerons ^^.
Nice chips and good for a Retro PC on a budget.
However I am not building retro systems for personal use. I am a collector and overclocker.
The point of the video was to review and overclock this rare version of the Pentium MMX.
The P MMX also has the benefit of under-clocking down to 120 MHz (useful for older games).
@@atheatos celerons can reach 800mhz with no cache
In the end... celerons are a total different platform.
Here is a more relevant comparison under exactly the same conditions.
I might do a K6-2 vs Celeron in the future, however yeah so many different parameters there. It will not be accurate.
I envy your agp graphics card -the 4600 it is way better than 4200 -I sed mine to play Unreal Tournament and the successor ut2004 -4200 64 mb model coud pull of 45 fps In onslaught and a amd 1700xp cpu -but it will run on lower cpu even a Duron 600 which your cpu might come close to in performance
I actually have a big AGP VGA collection. And many of the GF4 ti series. This Ti4600 was one of the latest additions and it was quite costly.
BTW Back in the day I got Ti4200 for my PC I paired it with a PIII/celeron. A very good and inexpensive combo.
@@atheatos In some sense it might beat even a nvidia 5700 xt ,maybe not the direct9 games but earlier
True as you can use older drivers that are faster.
I overclocked my IBM MII from 200 to 295Mhz. It wouldn't do 300 but it was still nice.
I have a lot of them that can do 300Mhz...
However it looks like this is the limit too.
It is very hard to go higher.
I will retest all of them when I do a Video.
@@atheatos Well, some MIIv at 2.2V can do 300...I had to cool mine with a peltier element... Otherwise, at 295mhz, it would crash after a few mins...
Exactly, all hit the wall somewhere around there :(
I had the same findings.
AMD K6-2 is basically a cheaper Pentium II processor, so even a faster Pentium MMX CPU overclocked to the same frequency you set to, in this case 420 MHz (which is extremely impressive, and could have been mind-blowing back then too), it would have trouble catching up with the K6 series in general as Pentium family in general is an in-order processor, while like Pentium Pro and II, K6 series are capable of out-of-order integer execution, so it was AMD's focus on integer. K6 series have had such crappy FPU, so Pentium processor at 420 MHz has an obvious advantage. At least until the Athlon K7 which was the first to take Intel off guard by designing something Intel thought was impossible due to the nature of FPU pipelines, a superscalar out-of-order FPU within the K7 which has turned the gaming table and was a worthy challenger to the Pentium 4.
Thanks for the detailed info. It is amazing that even K5 was an out of order CPU.
Yeah K6-2 is faster at integer and only lacks in FPU performance compared to the P MMX.
This explains all my results, like p MMX winning at Quake and UT.
This is clearly visible with Sis Sandra, but I did not use this in videos (maybe I should).
If the application supports 3DNOW it is a totally different story.
But unfortunately very few apps and games do so :( like 3dmark99.
@@atheatos Yep, some software are weird. It's usually due to the skill of the programmer and / or hacker coding it for specific application like CPU bound OpenGL rendering and certain geometry math like Mandelbrot, for instance. As for K5, they knew they need something more powerful to bulldoze Pentium processor, unfortunately due to the fact that Intel sued AMD, K5 was severely postponed until around '95, so they had to also try and develop K6 series as fast as they can to finally compete with the upcoming Pentium II at that time alas with the buyout of NextGen Semiconductors. Lastly, 3DNow! was just an additional instruction atop the existing MMX vector floating point infrastructure, so it wasn't as exposed as much that AMD stopped including 3DNow! ISA into Ryzen processors.
@@atheatos Finally, for a fun fact, the AMD K5 was actually based on a military RISC processor AMD also made, namely the 29000 series, and K5 was based on AMD 29050, with x86 to 29k hardware translator in the decode stage, and since the final 29k was capable of out-of-order execution, K5 basically inherited this performance enhancing feature.
Something is seriously wrong with your Quake results. Even the linked CPU Galaxy 300MHz Tillamook easily reaches >50fps. Either you made a mistake, or you benched at 640x480 in DOS which was bottlenecked by the graphic card and doesnt reflect CPU speed at all.
Also UT and Q3A results might not reflect the past accurately with T&L enabled GF4 - this skips FPU/3Dnow optimized geometry step from the rendering pipeline.
Yes Quake for SS7, I always bench it at 640x480. It still scales with CPU speed.
With same settings and better CPUs on this M/B I have seen a-lot higher results actually.
Also the performance depends a lot on the vga used in DOS, some older cards are actually faster.
Comparisons with other people are had.
In windows I have in total 6 3D benches. I think it is good I mixed also more modern stuff too.
I am not trying to be period correct.
I think for comparing K6-2 and PMMX this extensive set of benches was good enough.
in this time amd is cant playback mp3 in stereo in winamp , intel is killer in this time much much faster
Interesting, I have to check this.
@@atheatos and are you check ?
No, too busy >
