Won't hurt while you have it stripped.

Well, I threw the card in my rig, and indeed, there's tons of artifacting. It happened right off of startup, before the card even had a chance to warm up, so I was pretty sure it wasn't heat. Nonetheless, I removed the heatsink, cleaned it all out, repasted and reinstalled. No Dice.

I talked to the card's owner, and told him that we could take a chance baking the card. I told him there was a chance I would brick the card, but that if it worked, he could use it as a back-up card.

So, it looks like I'm going to bake my first video card this evening. I'm looking forward to seeing if baking fixes the problem. Should be fun :)

EDIT: If I can get the card to work, would it be ethical to sell the card, with full disclosure that it was baked? What is the outlook on life on baked cards? i.e. how long do they usually last before needing baking again? If I could get him $75 after a successful bake, I'm sure he'd be happy.

Did you try to stress test I had someone with the same problem with a XFX 5770 it would artifact and over heat. He went bought new card and I bought his 5770,clean out fans and board re pasted.
Tested it ,updated drivers to the latest ones and card runs fine no issues now. It's in my son pc running all his games at med.

It's artifacting right off the hop without even having to run a stress test. There's a little bit of artifacting right on the desktop after bootup, and Heaven is completely F-d.

Edit:

Also, on a different note, I was appalled by the (lack of) quality in the Windforce heatsink design/manufacture. The conductive surface that lies on the the chip and the RAM was very poorly machined. It was full of grooves, and was quite rough to the touch. It was just the bare aluminum of the heatsink, without so much as a copper base.

I hope the newer models of windforce coolers are built better than this!

That's to bad. Do you have any screenshots of the errors? I would say it's perfectly fine to sell it if the buyer knows the history. But I have heard that baking can last as little as a month or two if it fixes it at all.

It sounds to me like it's the memory and not the core though. Usually (in my experience) if it snows it's the mem. If you get lots of lines it's the core. I didn't read all the posts, but I assume you tried to undervolt/clock it to see if that had any effect?

Does the cooler cover all the ram chips? If not a water block may save it. Not sure if a 150 dollar WB is worth it on a 50 dollar card though lol.

I personally won't touch an XFX anything. That said though, there is really nothing wrong with a rougher finish on a heatsink (contrary to popular belief). A rougher surface can actually increase the surface area. However I can see the opposite being true with thermal pads sitting on the hills and not getting into the valleys like thermal grease would.What is more important though, as you mentioned is materials and TIM quality/quantity. Too much can interfere with (insulate) heat transfer and too little can have a similar result.

I'm actually running a reference XFX6950 in my rig as a back-up graphics card. I'm actually pleasantly surprised by how nice the card is. C/W with backplate, and at stock clocks it's actually inaudible.

Yes, XFX can make decent stuff. It's just I've heard too many people having problems with their stuff and then reneging on their warranty. Bad PR imho. Maybe that's why yours is doing so well. They didn't mess with the reference design.

Baking didn't work :( Card still has the same problems...

Oh Well, I'll give it back to the owner, and say so sorry, nothing I can do.

He already bought a new 7850 anyway, so no biggie.

! thing to help temps is to keep the fan/fins dust free, so clean the thing just as a precaution/routine. I keep my rig super clean with the use of a tooth brush and the vacuum
