"just" need 20 more FSB ;)

try it with REX bro, i had serious fsb difference compared to p5e3 prem even on ambient with quad cpu... nevertheless very nice result!

My Rex are weak than this board,  p5e3 premium has an incredible imc compared with mine Rex 

I only have one s.775 board (P5E3 Premium) and never had REX myself, but my board worked 1000 6-7-5-20 first boot 2x2GB Hypers.

Excuse my lame question, but I've only tested it with E6400 on water for 4GHz 32M low clock. I see you have modded it, so which voltmods are "mandatory" for this board if I want to bench e.g. E8500 on LN2? I see vPLL and vCPU on the picture.

Vpll mod is "mandatory" if you want to push Wolfdales and Yorkfields (also low-cache ones) on FSB, Vcore mod is "mandatory" if you need more than 2.05 real Vcore. Other than that, a P5E3-Premium is pretty much a Swiss army knife.
