Problem with gtx560 ti soc

[Chessum]

Hi, I'm having problems with my new gtx560 ti soc.

What happens:
Not so demanding games work fine but when I start something more demanding like The Witcher 2 the computer shuts down as soon as the card starts rendering. First I thought it was a overheat issue but the gpu-z log showed that the temperature only was 53 C when it shut down. Then I thought it might be that my Corsair 550W psu wasn't enough (altough they recommend 500w so it should work...) so I brought the card to a friend with a similiar setup but with a 620w psu. Now the computer didn't shut down but instead showed a black screen for about 1-2 seconds every 10 seconds or so. We tried with the 266,270 and 275 drivers but neither showed any improvement in gameplay.

What can I do about this? I read that increasing the voltage might help but I don't want to void the warranty in case it doesn't work.
Also, Is my psu too weak to handle this card? Would be good to know If I decide to look for a replacement card.

My setup:
q6600 2,4 ghz
4gb ddr2 ram
Asus P5N-D motherboard
2x7200 rpm hard drives(320 and 160 gb)
Corsair CMPSU-550VX 550W

 Just to confirm it is in fact the card   (Which I suspect it is, and if your friends rig is still available ).......Download and run Intel Burn on his rig with  his Video card installed to establish a clean running base line.........then(R&R) swap your card in and do the same.........If it fails, moving voltage up or down is  not really relevant, as...........

 The card does not perform as the distributors/designers intended .....Sounds like some on-board memory is failing.......RMA..........If, on the off chance the card passes this test, come back to us and we will work together to resolve the issue.

Thank you for your fast reply Aussie Allan.

Yes, my friends rig is still available.
I will download intel burn and get back with the results tomorrow (probably).

Update

I talked with several people who have had the same problem. None of them managed to solve it. I  spoke to the dealer and they told me to send it in, so thats what I did.
If it they don't find anything wrong I will post again.
Thank you for your help Aussie Allan.

 Don't get me wrong, I love gigabyte product, But the SOC series has seen a lot of activity on this forum and then some!

 I do believe most people would be better off buying a stock card and clocking them, them selves ...... Effectively this is all gigabyte has done (and every other manufacturer)... At the very least this would save some money and disappointment when the card doesn't reach the dizzy speeds you expect because ......."it's advertised" Just like CPUs..... Some clock like demons, some get not quite there!.......if you got under the bonnet of the SOC card and reduced the clock to a stable speed, ..... it could be as little as 20Mhz and not even noticeable in real applications or gaming!

 I purchased a stock  XXXXXXXX GTX-480 and admittedly on water, clocked it to 950Mhz.......and saved myself enough to buy 2 new hard drives.

 I've not seen Gigabyte spelt that way before Allan!

Exactly so. Overclocking is not something that readilly lends itself to mass production. I would agree that often the people who have managed to cure this issue have been the ones who have downclocked all the settings to those of the standard card and then applied their own overclock.

 That's because it spells Zotac with With 3 silent Xs.....AA
