View Full Version : Whats the highest voltage you should perma-run your cpu @ on water?

Well, for whatever reason (concave cpu, bad hsf installation, combo of both) I get horrid temps on my E6300. Knowing the potential of the chip and adding in the longtime desire to try out watercooling, I custom made my first setup.
I'm curious if anyone can tell me how much voltage is a safe amount to run the cpu on 24/7? Im not talking about never turning my pc off, im talking about not just upping the voltage and OC for a benchmark then turning it back down.
Just need to know what numbers to stay away from and what are safe for the long run/perma stable OC i end up with!

If you want to be relatively conservative I think you're pretty safe at within .1v of stock as long as you're keeping within sustainable temps under load.

maybe im misreading but .1? So.. stock being 1.315 i believe, you mean 1.415? Cause TBQH on air ive been running 1.450 =p

I'm pretty sure that you can get up to 1.45v on C2D and still be fine.

so 1.5 on water is a bad idea? If so then I hope heat is the only thing limiting my OC, cause if it isnt, then I might have just bought a WC kit for looks >.<

I ran 1.525V 24/7 on air. I am sure it will be fine on water.

I ran @1.4875 24/7 on air.
I have yet to further OC since I am on water now, but try to keep it in reasonable temps of course.

I have run up to 1.65v through my E6600 B0 ES for months on end 24/7 full load, with temps sometimes hitting 71c. It still clocks exactly like it did when I first got it ~8-9 months ago.
The chip and loop in sig.

Same here no problems with a e6600 at 1.65 sometimes even @ 1.7 with a mini aquagate, hits around 40c on full load .. what type of temps r you getting?

I would say it does depend a lot on your temps but I believe electromigration happens due to both heat and voltage. I would therefore say keep the cpu below 70°c and the volts below 1.6 (actual).
I dont tend to go any higher than ~1.55v (actualy idle), but thats mainly because my single rad doesn't cope well with more.

well with vcore not even at 1.45 I hit 70's under full load so .. I guess i'll wait for watercooling then Ill start moving towards 1.6 so long as my load temps are in the 40's? That seem safe/sound?

TBH I can't see any damage running a C2D into the 70's (in TAT or coretemp) actually if its only for short periods. But ye, 1.45 is considered safe for air

If your just going for a benchmark then I guess that much voltage and heat is ok. I'd never run 1.6v and 70c+ for any length of time. Frying a $300 cpu isn't in my budget. Some cpu's/mobo might withstand that sort of torture then again... I've read more than a few posts on XS from people who ran less voltage and had less heat only to see there hardware cook. I'm not happy unless my temps are 50c or less for a 24/7 OC.
