Just ran one more quick one @ 945. Seems like I still have some room with these on stock cooling. Screenie in link.

Have you tried with another PSU? Are you sure the cards are sitting properly in your slot? I had a 300 case that was slightly warped and cards didn't sit quite right as a result.
My DCUII, which is the predecessor of the matrix, does 1000Mhz at 1.15
yeah that was the first thing i checked, it's perfectly in the slot i had my Noctua NH-D14 off today so i triple checked it while i was able to see it clearly, iv'e tried 2 different PSUs, right now i have it on my Corsair Enthusiast 850watt, it was working on this PSU just fine when i first got it. Yesterday evening i hooked up the Corsair professional 1200w and it didn't make any difference, i can't believe at one point i wanted 2 of these, if i can get just one of them to OC to 900-920mhz i wouldn't need/want a second one.
I didn't think you would have issues with TX/HX PSUs but it was worth a shot.
How high are the temperatures getting? Do you have the fans locked on medium/high? Or on a profile to start on low-med and ramp up? I have to keep mine cooler than the 'stock fan profile' would allow for it to be happy in the 900s Mhz. It gets to like 80 something on normal fans but if I set the fans to start on like medium and go to high if it hits like 60, that works well. It rarely exceeds 55 even at high vcore. The matrix has bigger fans so you won't have to set them as high. That should solve any temperature issues. Once you get one that you know you want to keep, you might want to reseat the cooler. I thought their TIM was crapp. I replaced with MX4 and it took a good five degrees or so off my load and idle. That's pretty good. You're on the latest drivers from Nvidia?
I think it's odd that you are having issues with these cards and I'm sort of tempted (once you get the temps sorted) to wonder if there is an issue elsewhere in your system that is causing this somehow. You've tried the card in another slot right? It'll only pull 8X in the second slot but it's good to troubleshoot.
Maybe you got multiple cards from a bad batch. That temperature is fine and artifacting in PS is definitely screwy.
Happy to help. Downloading the file now. I will run it and let you know in a few minutes.
This is my system btw
2600K
4.5Ghz
Asus Maximus IV 1809 bios
1600Mhz 8 8 8 24 2N 2x4GB DDR3
120GB SSD boot
GTX 580 DCUII
I got 6700 points at 840Mhz... Hang on though had 'adaptive power' bs on...
K, 7158 @ 940Mhz. HTH.
Just FYI, the cores are not cherry picked.
You are paying for what they have done/added to the PCB.
Which imo may help if the core is up to it.
Aslo, that you can find other cards doing more with less v means very little.
The very few that have crazy clocking cards are going to post all about it, where everyone else doesn't.
I've had/used over 20 580's, not that I really do much air testing as it's pointless, but I've never got close to 900mhz
Though thats just a number, what should really matter to you is, how many more fps does this card give you over the last, not some silly % number for the overclock.

That's what i got at 940 back on my old thread with my card that started artifacting on me.

but see, i had 940 at 1.125v and eventually i kept having to raise the voltage because it would crash or artifact while i was playing, all while keeping temps in check, finally i decided to make up a ridiculous benching method, like running 3 GPU heavy simulations at once and i found out 890mhz required 1.15v, long story short, i RMA'd, got this one, and the same thing happened, only it happened quicker because i went ahead and used my little benchmark method on each clock and voltage, artifacts appeared and didn't go away, even at stock.
The good news is my artifacts are gone now and before i pack this one up in 3 or 4 hours to sip it back off i'm going to mess with it again, my new one should be here around 8am or 9am.
is your 940mhz at 1.15v?
I ran that test a week ago. But with dual 6970s not 580s.
8566 on high!

Sorry for the threadjack but no one else ran this test.
I don't mind at all, in fact, here is how to run dual GPU's on the benchmark.
open up the FFXIV Benchmark folder, the open the data folder and rename "FFXivWinBenchmark" to 3DMark06
Next Download this:

Extract it and place it inside the data folder where you renamed the file. Then run the benchmark using what you just renamed and it should screen wrap and use both GPU's.
If you've done this and still got 8566 then that doesn't seem right, a couple of 6870's not overclocked can hit 8500 with no problem, the 6970's should be atleast 20% better.
