It didn't like 250/200 MHz. Artifacts on the screen and I couldn't shutdown without pressing the power button. I suspect the memory timings were too much for it.

240/190 MHz worked, but the results for Half-Life actually dropped after overclocking, that is, from 15.33 fps to 15.07 fps. Not sure why this happened, but I assume it didn't overclock properly.

Here's a photo of the two PCI GF2's.

At any rate, I've put Savage 4 Pro+ back in the case. Powerstrip says it is running at 125/125 MHz. I added a 30 mm fan to it and will see if it can handle 130/143 MHz. The Savage Pro+ contains Winbond W986416CH-7 memory chips, which according to the datasheet, can run up to 143 MHz.

Well this was really interesting! Just put together VS440FX+Pentium Pro 233MHz machine with 128MB EDO. Now using Matrox Millenium II 4MB and Voodoo 1. Sound cards are GUS MAX and SB32 with 28MB memory.

I have somewhere GF2MX PCI -card, didnt expect that Pentium Pro will benefit from that.

I'm in the mist of a Pentium Pro build. I plan to run a 512K or 1M chip at 233 MHz. The board is PCI/ISA only, no AGP. I'm fresh out of working Voodoo cards and was hoping to use some unused 3D card from my drawer. Here is a list of what I have. Emphasis is pre-millennium 3D games, Could you let me know which card you'd pick any why? Thanks!

I’d be really interested to see radeon 7500 pci added to this list because it ends up being like twice as fast as a 7000 in some things. Which may beat out that geforce 2 🤔
