The attachment is my reference EVGA 570's, in SLI, at 920/1840/2250 @ 1.1v. You can see the max temps, they level off at 75C and 81C. I should add that this is at 20C/68F ambient temp. I keep the AC on when gaming, for this reason. Anyways, although I've only had the second 570 for a few weeks, I've had the first for over 4 months, and both are doing great at every voltage, including 1.1v, which I've began using more and more often. I had to minimize Metro so that's why you see the second card throttle back for one second before I took the pic. I used Metro, played it for 15-20 mins and then snapped it, just to show some specs and how everything's working.
So, I think that the reason this whole thread got a bunch of people nervous is because if someone's card blows, many are either #1. Contrary to what they say, they could have been ignoring/neglecting temps and they could have gotten too high, #2. It could have had something wrong with it, such as having been mis-handled or something, causing the card to malfunction, and although the card may not be working, the damage might not have anything to do with overclocking and the card isn't technically "blown", just simply not working, or #3. It was simply a bad chip and easily fried with even a small OC. I think 3 is the most popular reason, and its the reason why although not many companies besides EVGA come right out and say "Overclocking doesn't void the warranty", all companies RMA their cards because they know this happens sometimes, and if the BIOS wasn't flashed, they know you only went up to the max 1.1v, which they obviously consider safe because they will RMA the card if its under warranty.
A card dies and people want to complain or make it known, so they go on a thread like this. Which is fine. But what I mean is when someone that isn't signed up to this forum gets a 570 and it works perfectly, they wouldn't be motivated by frustration or anything to go out of their way to sign up to this site just to say "Yes I got one, I got what I paid for, it works fine, I'm content, nothing's wrong, etc..". So even if we hear about 100 "blown" cards on this thread, first of all they're probably not all due to ONLY overclocking (ignored temps, something else wrong, or just a faulty card), and even if all 100 or so we hear about really are blown, that's still only a fraction of a fraction of a fraction of the tens of thousands of cards out there. We don't hear about all the ones that have been working fine. So, I think that if anyone has actually dealt with a company that flat-out refused to RMA a card (after you cooked it and did not do anything else that might void the warranty) and the company claimed they wouldn't RMA because the card was overclocked at less-than/equal-to 1.1v, post the company and the specifics as a sort of warning for us. But unless a lot of people have that similar RMA-refusal experience with a specific company, then I think you should get the most out of what you paid for. Go up to 1.1v in games that need it, or as high of a voltage as temps will allow, and enjoy getting the most performance for what you spent, without
Basically, a 0.01% chance of frying the card shouldn't deter you.
(P.S.-In E-Leet, voltages are always off, and TmpIN1, the CPU Temp, is always 10C hotter than what CPU really is. E-Leet does this for some reason and just with the CPU temp, I've tested this with BIOS and other programs, always exactly 10C hotter, but I just still use E-Leet because its a nice small window and I've gotten used to it.)Edited by dph314 - 8/27/11 at 8:06pm
