it may be any of them, but they tell that usually you are not able to run EB at more than around 110FSB without the nod and then after usually at 124FSB, so you underclock it anyway.
Use E type, cause this way you'll overclock it a bit
Dual C366@550MHz 1.90V (History)
yet single PIII-S 512Kb L2 cache at 1400MHz@700MHz
BP6 (not modded yet)
256MB PC133 C2
GF4Ti4200-8x
Maxtor 2x60Gb - all on promise ATA133
Lite-On LTR 40125S@48125W!!!
Plus P4 system
My (3) BP6 systems all have P-III/1100E single CPUs.
They all run with 110Mhz FSB very stable.
They all deserve a 2ND CPU, but I'm nervous about doing the mods.
I'm waiting to see if someone else makes it to at least dual 1.21Ghz P-IIIs first. Keep us posted if you get there.
