Is my 4890 Toxic bad?

[allthatisman]

I bought this card used about a month ago:

http://www.newegg.com/Product/Produc...82E16814102840

The card worked fine, was playing some CS:S, stopped for the evening, was just surfing the net drinking a glass of wine, and all of a sudden the screen turns green and pixelated, and then goes black. I try to resart the computer, shut completely off... nothing.

I had an extra 7800 GS-KO, put that in, computer fired right up.

In hind sight, I never really checked the VGA cord, but I doubt that it was that... anyway the card was second hand, and the previous owner no longer has the reciept, and Sapphire demands that for any RMA, so it's a $130 brick. Fast forward a couple weeks, I bought an open box 5850 from Newegg, installed it today and the PC runs great. For whatever reason I get ticked that I just had to buy another card and decieded to reinstall the 4890 Toxic just for the heck of it... and of course, the machine fires right up with video and everything. Played some CS:S surfed the web, no problems so far.

Now my question:

Here is a link to a GPU-Z screenshot:

Is it normal at desktop idle for the clock speed to be fluctuating like that? It goes up and down every other second or so, and I don't think I have ever noticed another card do that before...

I am about to return the card, since I charged it and I really wanted to hold on to the 4890 for at least another 6 months, or until I could get a 5870 for ~$250... what say you all?

You might try running Kumbuster overnight, or some other gpu stress program to see if you can get your card to fault. From what I understand HD4*** don't like Furmark. I could be mistaken on that though.

LOL, I thought I was on the wrong forum when I read that!

Do you mean "MSI Kombustor"?

I ran it all last night... computer was chuggin right along this morning. GPU never got above 76 degrees. I would surmise that this card is probably ok...?

Haha ~> " I was enjoying some Dom Pérignon and suddenly my screen went on the fritz!!! "

It still sounds like a heat problem. I had a Radeon 9700pro do the same thing just the other day and it turns out the fan on the cooler was about to die. Of course, if I let the card cool down it works fine ..., until it gets to hot again that is, then its back to green squares or weird lines.

Granted these cards are quite a few generations apart, its at least worth a look as I've heard some 4890s run pretty darn hot. All i did was re-apply the TIM and slapped on a new fan to fix the problem.

I figured he might need a distraction.

Alas, some things can't be spell checked. :\
