hi all, after a bit of advice please, my pc had been running really well, was playing race drive grid and it was running really well and very smooth, now however when playing it the fps keep dropping right down and its gone really lumpy, also there seems to be a lot of jaggedness i spose to the edge of shadows and stuff, so is my 8800gts dying, things ive tried
a few different drivers currently 175.16
prime95 ran fine for ages
run all tests in sea tools
run 3dmark06, did notice my score has drooped by just under 1000 points from 12639 3DMarks to 11641 3DMarks
and as a final test i have reinstalled window, all to no avail
I looked at the pictures and I take it it's not something normal. Perhaps the video card really is dying out.
You might want to use Rivatuner and check the temperatures under load. You do not want this value to exceed 85C, although it can withstand up to 120C. Try underclocking the card as well. If the problem disappears, then the graphics card is probably dying.
Try downloading Rivatuner or GPUZ to check your card temperatures. This kind of artifacting is often down to high temperatures which may mean either your cards fan is clogged with fluff, or not working too well.
right just underclocked my card to core 500 (default 576) mem 800 (default 850) and this really didnt make any difference, if anything made it worse, was running at around 40fps and on the laggy bit dropping down to just under 20.
temps got to about 70 ish, so i think thats ok (have blown out card recently)
dont see it can be updates, i have tried reinstalling windows and it even does it on a fresh install
Gee, perhaps a defective part then? Here's some more ideas:
You also said FPS drops right down, which is usually the symptom of an underpowered video card. Try using a different rail for your 6pin connector.
Grab ATI tools: http://www.techpowerup.com/atitool/
Then hit "Scan for Artifacts". Run it for about 5mins. Any yellow dots or mark means the card is producing artifacts. If it passes, hit "View 3d window" and run it for around 10mins. Watch your temps, ATI tools heats the vidcard like crazy. If at any point it freezes, it means there's something wrong.
If the above doesn't help, I'm fresh out of ideas. RMA it I suppose.
right had ago at all that, same on both connectors, didnt put out any errors in ati tool, but on the 3D view the fps were peeking around 850-900 fps with an average of around 812, however they did also keep dropping right down to high 500 to low 600, should it be doing that?
i think it is going to be a case of a rma, i just really want to be sure first as im in the uk and have to send it to Germany which will cost over £20, the last thing i need is to send it in just to have them return it saying there is nothing wrong with the damn thing
Sheesh...my 8800GTS 320MB peaks at 1200~ consistently, so something is off for sure.
It's very likely the vidcard has something wrong with it, but make sure it's not the cpu that's causing the sudden drops. Some simple cpu tasks such as playing an audio file or perhaps watching a video should prove it's innocence.
