I recently bought a used 6800GT - I'm beginning to think I bought a dud.
It was originally bought to upgrade my son's PC but I noticed that just at the windows desktop I would get the odd flickering line and if I turned the refresh up it would get a lot worse.
I contacted the seller and got into the usual "well it was okay when I sent it" conversation so I agreed to try it in another machine.
So it went into my daughters PC and all seemed well. Windows showed no sign of flickering at 1280x1024 at 60Hz or 75Hz. So I just put it down to something odd about my son's PC and let the seller know all was okay.
A week has passed since and when looking at my daughter's PC I notice it had 3DMark03 that I must have installed a long time ago so out of interest I ran it.
This shows that the card cr@ps out on most of the tests to varying degrees - textures mixing and big triangular tears\artifacts (whatever you call them).
Buy now I pretty much resolved to having bought a lemon and don't really have any recourse with the seller - a leeson learnt.
However, I notice that it has an after-market cooler (an Arctic Accelero X1). The seller claims it has never been overclocked - the cynic in me wonders why he splashed out on a better cooler.
However, before, I give up I thought it might be worthwhile reseating the heatsink. I have artic silver for the GPU but I notice that the RAM is interfaced with sticky thermal pads. I assume that I will need to replace these but am not sure where to get them from.
I can find plenty of pads but these seem to be the thin tape used for CPUs and GPUs. What I need is the spongy pads.
As a last resort I could buy another cooler.
Any ideas or advice.
Cheers,
Nigel
Also is there any reliable way I can tell what speed it's running at. Could it be that it is running overclocked - given that I've just installed it and used the stock nvidia drivers?
