7900GT artifacting

post #1 of 24
Thread Starter 
Well, when i first upgraded my GPU i got a 7900GTX, which turned out to be defective, so i RMA'ed it, and rather than take a direct replacement, i got a 7900GT and my G.Skill RAM.

Well now the 7900GT is being retarded and giving me some serious artifacting. I think its the cards memory. This is why it needs heatsinks on the ram

Examples:

BF2142

I don't think the artifacting needs pointing out on this one.

EVE-Online

Those lines aren't meant to be there

I've done MULTIPLE driver reinstalls etc, a reformat a while ago, and multiple reinstalls of DX to make sure that wasn't messed up.

I'm gonna go test out BF2142 with my 6200 and see if i still get the artifacting.

Also, the 7900GT is now apparently End Of Line, so i might not be able to get a replacement

I'm hoping i might get a 7950GT as a replacement instead

My 7900GT cost me £250, and the 7950GT is now about £240. But thats just wishful thinking i guess.

So long as i get back a 7900GT or something better. They better not try and fob me off with a 7900GS.

Hi,

Have you tried your card on another computer. Perhaps you have an accomodating neighbor or friend perhaps who has a rig with a PCIX slot. I know that the card is probably defective, but a little confirmation wouldn't hurt.

Swapped in my 6200.

Plays BF2142 without any artifacts. Infact, the game doesn't even crash anymore!



Even in ATiTool, as soon as the 7900GT hits 65c it just starts artifacting. I tryed underclocking it, and still got artifacting.

The artifacting has got progressively worse.

I'm pretty confident that the 7900 is just knackered.

Now i have to cope with using a 6200 will i get a replacement. Still pwning up n00bs in BF2142, so its not all bad

Also, make sure your PCIx speed is locked at 100mhz. Someone posted here a few days ago that the AUTO setting was seriously messing with the PCIx speed and screwing up thhe GPU.

System isn't OC'ed, so that's not an issue, nor a possibility.

Haven't even received an RMA number yet. Hoping this process won't take too long.

EVE-Online is pretty much unplayable with the 6200.

Although strangely enough, to 6200 handles BF2142 really well. It might be on all low settings and 'high performance' in nVidia control panel.

The frame rate drops where there are effects like helo engines and explosion etc, but apart from that, i;ve been pwning n00bs happily.

Hell, i got 80+ in a round Seems the game is nowhere near as buggy as i thought. All my problems where actually from my faulty card.

I've had NO issues with the 6200 AT ALL.

FYI - EA are released a 1.05 Patch sometime this month. http://www.totalbf2142.com/forums/showthread.php?t=8548

all you need to do until you get some memory cooling is lower the clock speeds on your memory

I've been using my 6200 last night and this morning.... God i hate that thing.

The 7900GT is back in, and currently is artifact testing at 375/1000 down from the stock BFG OC of 475/1360.

No artifacts after 15 minutes so far, 61c.

Before it was at about 65c load, and would start artifacting.

Hopefully this underclock will let me play without trouble until i get a response about from the retailer about RMA'ing the card.

Started up prime as well to help simulate a gaming situation.

Was stable at 61c, but when the CPU is at load the case temp goes up slightly, and hence GPU temp goes up a degree or two.

Card started artifacting again.

It really is very very knackered

Well, still no word back from the retailer.

Oh well, guess they dont work saturdays like i do, lol.

I'm hoping i might be able to just send the card back to them and get a full refund, rather than wait 3~4 weeks for them to get me a replacement from BFG.

FYI - a full refund of what i paid for the 7900GT would be about £250.

Guess what i can get for £250.



*cough* 7950GT 512 *cough*

It seems unlikely that they'd give me a refund, but on the other hand, how can they refuse? the product is faulty!

Although i have had it 7 months, lol.

But if i get a refund...

Free upgrade!

The 7950GT from overclockers.co.uk is about £200, so i;d have some money left over to grab a vf900

Just gotta hope they'll give me a refund. It'd be faster for me to return one card and buy another than to wait for a replacement.
