So I've got a cool IBM intellistation Z pro with a dual socket 8 board but originally came with only one Pentium pro 200 w/ 256K L2. It ran perfectly stable at 233. I bought 2 1MB L2 200s and a VRM which run great on the board. Quake 3 went from slideshow to playable with r_smp 1! But with 1 or 2 cpus would crash at post running at 233 🙁 Intel really was pushing that wild cache back then.
Not content with giving up I wanted to try to overvolt these chips. These are the first ones to use VID pins just like socket 370 but only have 4 and are either open or grounded to set up to 3.5V. My chips run at 3.3 so I figured I'd try 3.5. I wrapped a small bit of wire around VID0 and VID1 and measured 3.42 on the bottom of the board. (3.28 without)
It was enough to boot into Windows 2000 and run just one timedemo of Quake 3. Would reboot after every time. A little disappointed and that extra 33mhz took me from 32fps to 36 with a TNT2 M64. I don't think I want to give it any more voltage but I'm certainly open to ideas and thought others may benefit.
