Wait a minute, the octagone shaped chip is the cache? Anyway i need to buy now fine sandpaper, because the copper pads have sides and i have to make them perfectly even. Thanks for the paste warning, i will be careful with!

Hello guys, I'm trying to upgrade my badass Pentium Pro machine with an Pentium II 333MHz Overdrive CPU. However the factory cooler is loud an not good for overclocking, so I have to find a solution. Currently I'm experimenting with copper pads and may on the top one I could fit my Zalman CNPS90F …

Anybody knows FPS meter for Windows 95? I want to do some benching with this computer with different CPUs. Also Unreal timedemo benchmark does not work for me and I do not find the solution in Google.

You go for high FPS in low resolution or why the heck 1 GHz CPU for Voodoo 2? That is even for a Voodoo 5 5500AGP a good strong processor. I use a Pentium Pro 200MHz for Voodoo 2 SLI and I can enjoy both’s best at 1024x768 resolution.

I see yours has got a fan. My PP180 machine came without a fan, just a passive HS glued to the CPU. It runs very hot and I've worried about overheating. Of course, i would not use them without proper coolong. The factory cooler is loud, so I installed a modern Zalman on it; https://i.imgur.com/ …

Because my Pentium Pro desktop machine did not have Pentium Pro sticker at the front, I had to buy an unopened, factory sealed CPU to have the sticker. I've got one from Ebay around 90USD with shipping included. It is the weaker 180MHz version with 256K cache, but whatever I just need the sticker. …

It is really imteresting an 1995 cpu can run at 266MHz with that modification. I woonder a 96' 512k version might could hit 300MHz? Anybody can adwise hot to turn off vsync on Voodoo 2 SLI for Quake benchmark? I don't find Vsync as option to turn on/off.

For those who are considering this mod for themselves, a great source of such 1.0uF capacitors is Socket 370 Coppermine chips whether Pentium 3 or Celeron. These are very inexpensive especially if broken because gold refiners don't want them usually. It's much more expensive to buy new capacitors …

Those 600nm PPro's were limited to 133MHz ES and 150MHz retail. I have half a dozen of those black 1Mb PPro chips and they run just fine at 233MHz. They can even be undervolted which is good because each draws about 15A at full load. Most VRMs for Pentium Pro are 10A or 12A rated, so they can do …

It can do 70MHz FSB. With 3x multiplier I would get 210MHz. Because no significant bump in FSB, hope will handle that speed with 50ns RAM without any trouble. Update, Today I did some overclocking tests, and it is actually booting at 210MHz, 233MHz and also at 245MHz. I updated my first post with …
