Hi,
I've recently bought an NVidia 6800 Ultra which intermitently freezes during 3DMark05. The freezing causes everything, including mouse activity, to halt for a few seconds at a time.
I have monitored my system temperatures and note that they idle as follows:
NVidia 6800U GPU: 53degC
System temperature: 34degC
Athlon 64 6300+ temperature 45degC
And at peak (throught freezing spells):
NVidia 6800U GPU: 72degC
System temperature: 35degC
Athlon 64 6300+ temperature 57degC
If I run Prime95, then I can get the CPU up to 62degC, but no higher.
I believe the danger temperatures for the CPU to be 70degC+. However, I could not find anywhere what the max temp is for the GPU. though I note that the NVidia Tool offers a default threshold of 115degC.
I have swapped out the videocard for a Radeon 9800 Pro, and whilst the performance is obviously slower, it doesn't freeze.
I have aso experienced intermittent freezing whilst playing World Of Warcraft on full settings.
I have swapped out both Crucial memory sticks with no difference.
The motherboard is an ASUS K8N-E Deluxe.
My next courses of action is to lend the video card to a friend for him to test on his machine.
Anyway, you'd think this is a cut-and-dry case of videocard problems. Well, so did I. I sent the card back to Scan Computers International, whom I bought the card from, and who claimed to run the card through a half hour test on doom, far-cry, ,and 3dMark05 with no problems (and they charged me for the pleasure....).
I also note that NVidia monitor shows the GPU Memory Bus speed permanently over the redline at 1100, whether idling or at load. I don't know what this reading is, but suspect it is misleading to the cause of this problem.
Anyone have any ideas where else I could look???
