Overclocking my 570s.

I have 2 evga SLI 570's OC'd at 797 MHz. if I clock it any higher than that and run the Heaven Benchmark my monitors go blank and I lose video. usually I have to reset my computer. I have the Gold 80 plus 1000Watt Coolermaster PSU. And I just put it in last night. I had a crappy 900watt that when Id OC it would just power my computer down mid game of benchmark. All I can assume is my video cards are at their highest clock without errors. But when I run OCCT for 15 minutes it as 0 errors at 835 MHz. I guess im just confused if theres a problem at all? I see no Artifacting. And when im at 797 I see nothing wrong ever. What do you guys think? My Specs are in my Sig.
 
Do you have the 570 SC model or just the 570 you OC'd? I ask because I think evga parts bins for the SC models.
 
What's the question?
You haven't increased voltage I take it?
I run my 570's at 850core / 2025mem with 1.038v. They'll do 900/2100 with 1.1v but I don't like to run them 24/7 like that. They pretty much rock at that OC at 2560x1600.

EVGA no longer bins their cards:

And I agree with Brahmzy. You need to increase the voltage for both cards in order to push them further. It's possible that one card may overclock further than the other with a given amount of voltage, so it's unlikely you will reach extreme clocks on both if one is holding you back. You just gotta test them out individually and together to see how far you can go and then decide where to meet in the middle.

I don't know man, do you have any other direct EVGA statements? The only reply in that entire thread that was made BY an EVGA tech said this:

Re:Does EVGA 'bin' there vanilla GTX580 - possible answer in post Monday, January 03, 2011 8:08 PM (permalink)
Just because a card can reach SC speeds does not mean we will make it an SC card. It is possible to get a vanilla card that can reach or exceed SC speeds. SC cards just mean we guarantee their stability at the SC clock.

No where in that statement do I see "we do not speed bin". Sounds to me like they don't care if a vanilla card will OC, they will only chose the ones they want to make them SC cards. That, by definition, is what I consider speed binning.

All the rest of the posts below that are from customers who can not verify anything.
 
Besides, I don't place too much value in what an EVGA tech says, considering the ordeal I went through getting my card working. They had absolutely nothing of relevance to help get it working, it took me a week of experimenting to find the PCI-E bus issues the card didn't like, just to find a workaround that was acceptable.
 
I haven't come across anything else, but I haven't really been looking all that hard either. Based on the statement from that same thread, it sounds to me like they make a decision on how many SC card orders they need/want to fill and just test each card to see if it will go to SC speeds at a given voltage. But again who knows? Maybe we're reading too far into it.

All I have come to understand is that if you buy an SC card, they will send you back an SC card should your's happen to break under the warranty terms. It doesn't state anywhere that they owe you a better overclocking card. Not to mention, a lot of user feedback has shown that the "vanilla" cards and SC cards seem to share the same overclocking ceiling anyway. Very few have made substantial gains without drastic modding, and even then those are outlying statistics.

I doubt we'll ever get a straight answer from EVGA anyway as they probably need this sort of "mysticism" to sell cards to those who are willing to pay the extra $10-$20 to *think* they are getting a better version. :p
 
I volted to 1100. Was able to clock it up to 835MHz and Still no frame increase in the Metro 2033 benchmark. but it doesnt lock up anymore. So I guess thats good right?

Why do no one use Rivatuner anymore? You can change the voltage all you want the driver scans the voltage tables on the bios and selects one of it. that's why the cards will always boot.
Btw did you enable vsync?

No. No Vsync

no wonder it flickers. A LCD 120fps receiving images from a gpu that doesn't know the limitations of the monitor. Now it manage to create like 300fps and is awfully out of sync with the LCD.
Enable vsync so they can sync with the LCDs limitation

Im not even hitting 120HTZ. I'm running a benchmark.

That's is a BOATLOAD of voltage for this card. You're a brave man. Pretty sure you can have 835 stable with WAY less voltage.
