Hey folks, thought maybe somebody here could give me a clue... I bought a Diamond HD5870 to replace a burned out 9800GT on Sunday. I installed it on Sunday, put the latest drivers on (11.3) and everything seemed to work well. The following morning, however, I noticed that after booting to the desktop I got little green dot artifacts on the desktop. After being on for about a half hour these artifacts went away and the card performed as normal. This has repeated on Tuesday morning and this morning. I've tried re-seating the card and moving it to a different slot without any change in results. I've also run FurMark and GPU Tool stability tests and found no artifacting. Could this be anything other than a bad card? System specs below:
Intel Corei7 920
9GB RAM (3GB pre-installed, 6GB Corsair XMS)
WD Caviar Black 2TB primary HDD
Corsair HX1000W PSU
Diamond HD5870 (appx temps: 45C at idle, 75C at load)
might be your monitor, check it for dead/stuck pixels.
I had the same thing happen on my gtx 470 the video cable coming out of the back of my pc was (ever so slightly) loose, check connections, I had green pixels and a few green stripes.
Switched out the DVI cable and no change, still getting little green dots on cold start. After a half hour they go away and everything runs normal, which leads me to believe it is not dead pixels on the monitor. Should I return this card (in which case I would probably have to get a HD6870 to replace it) or is this something I should learn to live with?
I'd say your best bet is hook up the monitor to another pc or even a laptop, if there's no green dots, then I'd check with tech support for your video card, try for a rma on the card.... Does your card just have vga out, try that as well. Best bet though is trying the monitor on another laptop or pc
I've switched out monitors, same result.. I really don't think this is a monitor problem. Seeing as how these artifacts only manifest themselves at cold bootup, and how the HD5870 requires more power than the 9800GT (2x6pin power vs 1x6pin) could this be a PSU problem?
I've seen weird problems due to a bad PSU, but the first suspect here is the video card. Don't try to live with it, it's a fault. RMA the thing and hopefully it was the culprit.
OK, thanks. I bought it from Fry's so I'll see if I can do a simple exchange.
Sounds like there is an issue with a heat pipe that is not correctly removing heat until it gets good and hot. Rare, but I've seen something similar on a CPU cooler where one core couldn't go past 50% until the heatsink had gotten good and warmed up.
