i7-950 Voltage?

post #1 of 9
Thread Starter 
my i7-950 is at stock clocks and the temps were gettting to 79-80c max with the ECO advance liquid cooler after about 25mins of Prime 95 LARGE test..

i redone my Heatsink and my temps droped to 75c max on stock clocks after a hour of prime95 LARGE test..

CPU-Z says my core-Voltage is 1.208v

whats a low / SAFE voltage i can lower my cpu to to get the temps down

Lowering volts will only ever shave a couple of degrees. You'd be better off making sure your cable management is tip-top, get better case fans, change your HSF radiator into an intake instead of an exhaust. All of these will have the same or greater affect on your temps.

That's real high temps for stock clocks. Try lowering your Vcore to 1.100v and see if it's stable. I run my 950 here at work at 1.250v for 4ghz overclock. Try 1.100v and let me know how it goes. That cooler isn't very good at all. You should be able to put the stock intel one on and get temps better than that at stock.

Also, make sure your fans are both pushing air the same direction. Your temps really shouldn't be that high, there is something else going on with your rig.

bumped the vcore to 1.1v bios (1.088v in CPU-Z) and prime95 LARGE test for 1 hour and the temps are maxing at around 65c so about 10c Decrease.

Well looks like that can help. Find your right voltage for stock settings. Or find the Max clock for the 1.200v setting. You may be able to run 3.6ghz on 1.200v and have the same temps as you did at stock clocks on that voltage. Testing will tell.

which header do u have ur pump hooked to? I have had a few issues w my h50 in the past. at first i used a 2 pin to molex converter instead of using one of my mobo headers and it increased my temps alot. once i had it on a mobo header i could actually hear my pump and temps were better. thing is at that point my bios automatically set it to a low rpm because i have a fan profile on all my headers for silent so it was pumping low still so i set its header which was pwr_fan, to ignore and that helped alot too lol.

on another note you should try for a lower vcore at stock or go higher like Hambone07si said
