GTX 570 Voltages (1.1 and above)

post #1 of 12
Thread Starter 
I'm wondering if anyone is running their GTX 570 at 1.1v or above 24/7? I've been running at 1.16v to achieve some pretty nice clocks but I was curious as what can be damaged? I have an EK full water block and the gpu is on its own separate loop alone hooked up to an RX240 radiator. Temps have never broken 50*C under full load. There is also a good amount of airflow over the card in addition to the full block.

Basically, are there any worries as long as my temps stay low (below 50*C)? Or am I reaching/surpassing danger zone regardless of temps?

EDIT: Should have checked GPUZ first--apparently (even though afterburner is 1.16v) my card is actually only running at 1.128v under full load in GPUZ

Pretty sure that you'll be just fine, especially on water. GPUs aren't as sensitive to high voltages as CPUs are. I currently run 1.15 though my 470 (24/7 folding) with the stock cooler at 100% and I haven't seen any problems. Only time it doesn't like it is if it gets too hot in my room.

Well, I run my Gigabyte GTX 570 (Reference) at 1.1V for 900 Core, 24/7 FOLDING, not the best clocker, but 900 is good enough for me

It reaches up to 78C under load (Folding/Gaming). Graphics card can take much more heat than CPU. If you don't disable OCP, I'm sure you are fine.

BTW what clocks are you getting at 1.16V?

Yeah. Well there is a lot of fear of the 570's dying and this and that, but I wasn't sure if there was some issue with the cards or literally because people are doing this on stock hsf's and temps are getting a bit too high..although I've run my 570 upto 1.12v for a bit now, folding, etc and I assume if it was a lemon it would have died by now.

+1 for you--hopefully can get some more advice.

570's are only dying due to voltages being set over 1.1v and VRM's blowing as they enough once OCP is disable in combo with the 1.1v+ core voltage

480's don't have this problem cause they have more VRM's

1.12v stable 24/7 at 960 mhz core setting.

Not quite sure what you're saying? VRM's are blowing when? I didn't disable OCP as far as I know--but I do have an unlocked bios that said the only changes made were unlocked voltage and 100% fan speed. How do I check for the OCP protection setting?

I"m not making sense redface.gif
I shouldn't post on OCN when i'm sick tongue.gif

what I meant was
if OCP is disabled in conjunction with a high voltage set (1.1v+)
there are less VRM's on the 570 compared to the 480
so, disabling the power draw limiter and adding more voltage would lead to the VRM's ultimately failing and killing the GPU

.....tell me if that doesn't make sense.....

Haha no that is perfect. Makes sense. I have no plans to disable OCP limiter--and I thought I read somewhere that nvidia spec on the gtx 570's says 1.13v is max while staying within nvidia specs? I was just curious if simply going up to 1.15 or 1.2v would be a bad idea even if the temperatures are well under control with a full waterblock. Not disabling OCP limiter, no matter what.

idk
just don't disable OCP over 1.1v+

nvidia kinda cheaped out cause they're relying on the OCP to keep the card from dying even though they know voltage can be tweaked.....I don't think they planned on us finding out how to disable OCP

Great info, I appreciate it Mr.Pie. If it dies, I'll forward you the bill. tongue.gif

Nah.. it isn't the end of the world--There is just a lot of misinformation about the GTX 570 and I had a hunch disabling the OCP (which I have no clue why you would) seemed likely the culprit. I'm just assuming with good, proper cooling I can safely go slightly above nvidia voltage specs seeing as my temps will still be well below what the card is intended to run at, stock.

If I find out otherwise, you'll see me with a crappy GPU and I'll post here smile.gif
