Can i drop my voltage further?

post #1 of 10
Thread Starter 
Was just thinking i might be creating more heat than i need to be. DDr3 ram,
P6T6 x58 mobo and an i7920 that i put the blck to 180 for 3.6ghz, and then didnt touch anything else other than the cpu and qpi/dram voltages.

With an HAF 932 case and H50 cooler with the radiator fan set to intake air my idle temps are 35-ish and load temps are in the mid 70's most of the time or in the mid 60's when i am playing games like black ops or bc2. Assuming a typical 65F ambient temperature.

Mainly wondering:

1. How low could you typically drop voltages at this blck and still have a stable system. Most demading things i do would be probably be rendering video.

2. Would an average drop of 10c be possible simply by reducing said voltages.

Only way to find out is to drop the voltage and test for stability.

go ahead and try to lower the voltage.... I was able to drop my load temps from 68C at 1.25V (stock, seemed way too high!) so I dropped it to 1.1v and did stability test and seems OK. load is now 58C. I haven't gotten to a BSOD yet so I'll see if I can lower my voltage even more.

hmm sound like voltages need to have a fairly appreciable drop to see a good drop in temps

Yeah 1.225v for the cpu and 1.2375v qpi/dram and its not complaining yet, still 3.6ghz.

Unable to see your dram bus voltage.
setting that to spec helps stability.

Also, I see your dram freq and cpu ratio on auto.
auto hinders stability & in most instances.
auto volts , usually overvolts.

Dont let qpi/dram core voltage be more than .5(1/2) volt from dram bus.
ex: dram bus 1.65 qpi/dram core 1.15 is borderline to damage hardware.

Sometimes low voltage can be damaging if you arent aware of some limits.

Yea of course low voltage is better for cooling....auto volts or xmp etc are overvolted

How can i find out what to set it to?

I havent touched this because i dont know where it should be at.

Right now i have the qpi/dram and cpu both at 1.2v and i ran that occt test for about 4 hours and i didnt have any problems, then my load temps are dropping little bits. Max temps didnt reach 60c.

Alot of those other voltages in there i dont really know if or what i should be doing with them so i havent touched them and rig seems like its working fine....

Is there any rule of thumb about how far apart you can have vcore, qpi/dram and PLL voltages?

My vcore and qpi are both a 1.2v but PLL i havent ever touched and its sitting around 1.8v or so. Is that unwise?

Tried raising my blck a bit more without touching anything. At these voltages it looks like i can run stably at 3.7ghz
