So my method is going to be prime95 blend ~8 hours at night, and then change the settings in the morning for the next day to be the next overclock I want to test. Since I want to see where the limits lie with this cpu right now, I'm testing 3.8 ghz, which I think is where most people get their c2 955's on stock voltage or higher voltages, not sure exactly, but i think its a good high-end spot to start.
I'll use 3.8 ghz for the day, and p95 blend 8 hours tonight. I know I bag on multiplier overclocks, but my system is stock now and im just doing multiplier to get a rough idea where I am at, since I disable powernow! when fine tuning anyways. Core FID x 19 = 3.8ghz @ stock 200 fsb.
Interest to note - when I raised core VID to 1.45 (with the +.1v motherboard overvoltage), it wouldn't post (as in black screen upon start, didnt get to boot up screen or anything). 1.45vid+.1v over voltage should put me around 1.53vcore. Thinking it might be a similar issue that i had earlier, I changed my vcore the other way around - 1.35vid(stock)+.2v over voltage. And it worked just fine. This is 1.503vcore (i believe VID is a little higher than the actual supplied voltage).
I could probably test 4ghz, 1.55vcore, but I want to make sure my temps dont get too high, so that's why I'm testing 3.8ghz@1.503vcore. Idle seems to be around 32*C cpu, 31*C vrm though. Ill run a 5 min p95 to test temps on load in a minute.

mine came in at 1.325 and does 3.4GHz at 1.35 (1.342 because of vdroop)
