Well I had the day off work today and decided to take it out of the dell and do some testing before I assemble my pc.(my athlon xp is still in my case.)
I built a test rig out of spare parts I have around and the abit IC7.
IC7 (bios 26 {8-30-04})
Powersupply -fortron 400w (only 15a on the 12volt rail)
Vid card creative gforce 1 32 meg ddr
realtec nic
coolermaster DI4-8KD3B-01
assembly sitting on a bench.

( I know it won't run at those speeds but I was curious)

May not need to turn on the heat this winter with this puppy .
I lapped the heatsing(took forever and 7 sheets of sandpaper this thing was really dished)
Added a more powerfull cpu fan (30 cfm antec ball bearing 80mm)

Definitely going to add some additional cooling to the power transistors and hopefully with my antec true control I can get a better OC (this setup brought the fotron 400's 12v rail down to 11.5v)
Maybe add an xp 90 thermalright if I can get it higher.
Something stange..this processor will not run memtest x86.(tried in the dell...thought it was the dell,but when i put it in the IC7 it causes instant reboots on this board too)Memtest runs fine on my 2.4c northwood.I'm not sure why it will not run on this prescott.
