Any help with troubleshooting (HD7970 Matrix)

Hey all. I've just installed my new GPU, the ASUS HD7970 Matrix Platinum, and I'm having some issues with it. We'll call them... extreme teething problems. Straight out of the box, I've been having issue after issue with this card. I'd love to get it to work, because it really is a monster - glitches and problems aside, it looks stunning, runs nearly silently and FPS-wise is an absolute demon for performance. It's factory overclocked to 1100Mhz (clock) and 6600Mhz (memory) which could be causing the problems. Which brings us on to the issues...

To open, my system specs are:
CPU: FX8350 @ 4.4Ghz (CoolerMaster Hyper 212 Evo cooler)
RAM: 8Gb Corsair Vengeance
Mobo: ASUS M5A97 LE R2.0
PSU: 600W CoolerMaster Silent Pro
OS: Windows 7 Home Premium 64-bit

Initially, I was experiencing issues with texture flickering and some weird, black "artifacts" in BF3 and Skyrim. After updating every driver I could, these seem to have been reduced or removed, to give way to another issue. Textures would stretch across the skyline in BF3 after about 20 minutes of gaming - not consistently, but frequently. Artifacts and weird graphical glitches would appear on my second monitor, in Windows (somewhat reducing my assumption that it was a game-problem) 7 itself. For BF3, the card is operating between 60 and 80% load on my monitoring tools.

I'm faced with one of three problems, as far as I can tell from extensive googling:

1) The card is overheating. I'm reading about 57-61 degrees of heat in GPU Tweak at peak BF3, which doesn't seem high, but only one of the two fans is actually doing anything (at about 40% speed, set to hike up if the card gets over 60 degrees.) However, this is only a single area, so it's possible another part of the card - possibly the VRAM? - is overheating elsewhere on the card. As I mentioned, it's a physical monster - 3-PCI slots wide?

2) The card isn't receiving enough power. I won't lie - my PSU is a little below the recommended supply, but it's from a good brand and receives high ratings for efficiency. Research and reviews pre-purchase suggested that it would be fine, but I realise the card is stock-clocked to ludicrous proportions and is likely power-hungry as a result. However, I didn't want to put down money on a new PSU (my budget is constrained, and the card itself took a big whack out of it) if that isn't, in fact, the issue.

3) The card itself is simply unstable at stock overclock. In which case, I'll return it - I could lower the clock but, at the end of the day, I paid for that extra performance and I'd expect to be able to benefit from it.

I'd appreciate any suggestions. I haven't spent a massive amount of time with the card to run all the experiments I should've done or tested it with a lot of games, but this is seriously concerning me. Thanks in advance, sorry for the wall-of-text.

Alright, that's handy to know, thanks! Makes sense about the PSU simply shutting down - I figured that, since overclocks tend to be unstable if they're not receiving enough voltage, a PSU that isn't outputting enough might be the problem. Makes sense it'd simply shut down, though.

Drivers are pretty much completely updated (twice now, after I had some trouble with the initial install). Running the latest non-Beta Catalyst drivers (I intend to try the beta ones soon) and the latest GPU-Tweak.
 
I had a crappy PSU and it would turn off my PC if I play videogmaes. I got 1 KillaWatt Antec and I'm having no problems.
I have the 7950 and I can't play Metro 2033 because I have streaks running down the screen, I think it's the PhysX problem because you need it to play the game and Nvidia handles that. So I think some games may not be fully optimized to play on some GPUs. Batman arkham city runs without a problem. So try other GPU power hungry games and see if it's the problem.

I personally think the card is faulty, but make sure because the shipping wait sux.

I had a 3880 before this and the heatsink was loose and it would overheat and the screen would go black and the amd drivers would restart and my screen would flicker. I tighned the screws on the card and it worked fine. If your game works fine for 20 min and then craps out then some crucial part of your card might be overheating and not OC properly. I'd get an RMA. It might be a defective chip because the way they chose the chips is they have batches of chips and they test them and it seems like it works at that MHz so it passed to 1100MHz but they never caught it while testing because it never shut down fully probably, just my guess.

Hi I have the 7970 Asus Matrix and seem to be getting similar issues
the card running normally will show green light then blue up to red if under extreme processing. But it goes dead no light comes back hangs and on some sessions graphic shear and localised bit mapping. Not sure if its the card but my PSU is 1500w silverstone so power should not be issue. I have 12 gb of Corsair RAM, MBo is Rampage 3 extreme etc to sys should be OK. Running Windows 8 / 64 and when I contacted Asus they suggested I uninstall Catalyst as it can apparently cause these issues. I did that still having issues so I may be waiting some shipping time.
