I RMA'd my card after I was having problems with instability. The result of fault testing by Overclockers was:
"No fault found, the card ran all manufacturers tests for 8 hours stable, no crashing. Ran Furmark, Crysis, 3D mark vantage, Streetfighter 4, Heaven and Aliens Vs Predators."
It has been sent back to me today, after I asked for a credit note the day before they tested it (see Webnote 2) to purchase a better card.
I asked for a refund under the DSRegs and they've very kindly said I can have a refund, but I don't know where I stand with the postage. So this card could set me back an extra £24.68(£10 for testing, 2x Postage £7.34).
I still think there's problem with this card. It should run fine out of the box with the spec I've got.
In addition to my previous webnotes to OC's, I tested the 12V rails on my HX1000W with my old GTX260 (I'd RMA'd the GTX480SOC) and processor running the power supply test in OCCT. It was reading 12.14 in the BIOS, and 12.15 at a Molex with a Fluka meter.
Webnote 1
I received my Gigabyte GTX480SOC yesterday but it crashes when running Nvidia demos, sled, alien & endless city, particularly during intensive scenes. This happens at the SOC's shipped clocks of 820/1640/950. The only way I can get them all to run OK is when I underclock it to reference speeds 700/1400/924.
I thought it could be my PSU to GPU connections, but they are on separate 12V rails and I've swapped them around with no change.
I have plenty of airflow through the case and the CPU is WC'd with two rads right now. (setup is ready for a WC'd GPU eventually).
Nothing is OC'd atm. Typical temps for CPU cores is 21-36 deg. System 33deg
GPU V 1.06 MEM 1.54. I did see 78 degs for the GPU once.
GTA crashes badly at max settings, but it is a fresh install and I've not looked in that yet. Crisis Warhead seems to run OK!
Any ideas. It should really be stable at it's SOC stock speeds, or should I RMA it and start saving for a GTX570-580
Webnote 2
Further to my previous web note, I tried Farcry2, which again like the other games and demos I’ve tried, crashed after a while. I tried two Nvidia drivers. Orginal v258.96 as supplied on the Gigabyte driver CD, and the latest Nvidia driver v266.58.
I ran Prime95-64bit with my old GTX260 plugged in, just to check the cpu cores and RAM, and they seem to be OK after an hour.
I’m not used to my computer being this flakey and I was already a bit weary of the GTX480, but this card looked such a good deal at the time.
Could you issue a credit note so I can purchase a more stable GTX580, a Gainward GeForce GTX 580 reassuringly “GOOD Edition” for example?
