post #2431 of 3357
So I got bored and started playing around with my graphic card, I just wanted to know is this voltage to high for 24/7 use?

1.21v seems to be relatively safe as long as you can keep the GPU from hitting 80c.

The temps seem to be fine, they hardly go over 70 tongue.gif. also is that voltage to high for my clock or just about right?

All of a sudden my OC is now unstable under heaven 4.0, It was running pretty fine for countless of runs at 1228Mhz core (1.20v) with +300 Mem offset. I had this running on Heaven 4.0 for multiple 2hrs run before and now it seems to randomly crash to desktop frown.gif

Did anything change recently, gpu bios or drivers? How long have you had the PSU?

Only driver update chages, This PSU is just 3 years old if I recall correctly.

I really don't know what it would be crashing on you, but some thoughts...

You could rule out (or in) the driver update as the cause by reverting to the older driver and seeing if still crashes or not.

Was curious about the PSU because i think they can degrade in performance over time and I'm really not sure of the rate of decay. I wonder how close you are to exceeding what the 850W unit can deal with give the SLI setup? Ways i can think of to test for that kind of possibility involve spare power supplies that are known to be good.

edit: Thought of a way to maybe help figure out if its the PSU w/o needing another PSU. Dial your cpu overclock way down (so its using lots less power). If gpu still crashes, probably not the PSU.

hes nowhere close to hitting max power draw on that psu. it also shouldnt be degraded anywhere near enough to cause much if any loss of power.

earlz, are you sure you have the voltage sliders still maxed? its the only reason i can think of unless your cards dudded out.

No way this system is pulling close to 850watts, Im estimating about 600-650Wattstops! I used to have a GTX580 up until March of since I got this PSU, I understand that PSU's would decay but probably not this fast.

I will however keep in mind what you said, I'll try to dial down the CPU overclock and see what happens, I'll do this when I have the spare time over the week end perhaps.

hes nowhere close to hitting max power draw on that psu. it also shouldnt be degraded anywhere near enough to cause much if any loss of power.

earlz, are you sure you have the voltage sliders still maxed? its the only reason i can think of unless your cards dudded out.

Voltage sliders on MSI-AB? I never touched them since they dont do anything for my card.. I just used a bios unlock to get to 1.20v. Do those sliders actually do anything ?

watch the voltage graph in ab. if it drops from 1.2v, then yes it matters.
i dont think the voltage graph/monitoring does anything after you mod the bios though. bah. you can always check.
