I am using Xigmatek HDT-1283 with MX-2 thermal compound. I backed my clock speed to 3.6Ghz(9x400) and my vCore to 1.275V. Prime95 is running stable for more than 8hours now, thank you.
By the way, I've been trying to get my motherboard temp readings(NB/SB etc.) and voltages without success. Can you suggest any software for doing this? I've tried Everest Ultimate so far. I think I could get my speed a little higher if I start manually setting the motherboard voltages. Also, I'm sorry I'm being a noob here but where can I find the max VTT/vNB/vSB voltages? I took a look at intel's datasheet but I'm having a hard time interpreting it.
