i7 3930k max voltage under custom watercooling?

post #1 of 5
Thread Starter 
I just finished installing a new custom watercooling system on my cpu. I used alphacool nexxos monsta 480 rad, 4x Delta 240CFM fans, koolance pmp 450 pump, xspc reservoir, and koolance 380i waterblock cooling the CPU alone. Even under heavy OC under prime95 I never go above 65C on any of the cores, most stay around 60C under heavy OC, with cores never going above 50C at stock 3.8ghz. I am currently at 4.5ghz 1.42v prime95 stable, and temps are very low. Since I have a poor clocking cpu, I would like to OC further and increase voltage more, what is the max safe voltage for 24/7 OC that I can increase to as long as temps are very low? Thx for help in advance smile.gif

I'm going to say 1.35V since that's the advertised Intel max.

Most write-ups will say up to 1.45V. It's up to you.

I use 1.356V (multimeter) for 4.5GHZ stable and have had no problems

Thx for the help, I will keep it at 1.45v or under unless I buy the intel tuning protection plan then I may risk it and go a little bit higher, but for sure UNDER 1.49v. smile.gif

BTW I have tried using lower voltages, 1.41v for 4.5ghz gives me BSOD 0x00000101 which means increase vcore, at 1.42v it is prime95 stable. THx for help biggrin.gif
