Except that guide only goes up too 1.55 which ain't near enough juice for benching. I'm working on a vcore mod for the Epox. I have the PWM pin out already and it looks to be fairly easy.
I'll be interested in seeing your mod. The Abit NV8 allows voltages up to 1.7v. Next after that is 1.85v and while I am crazy, I'm not stupid...
You are absolutely correct, 1.55v is useless for benching - especially for Palermo Semprons and Venice A64's. I have to use 1.7v to get max oc's but it's all good since I have good air cooling.
You get a combination of motherboard voltages and pinmod voltage. If your board allows for 1.55v then with pinmod you'd be able to give upto 1.95v. I don't think you read it properly.
If you have a board which only allows stock voltage then your max pinmod would be 1.55v which would still allow for more of an OC over boards standard voltage.
