280x Questions - Page 2

post #11 of 26
Hopefully new card works out for you. Had the exact same thing happen to a 7970 of mine, coil whine and then just died. Im running 2x 280x in crossfire now. Some things ive noticed:

I seem to get a lot of artifact with the beta drivers, returning to the normal ones corrects the issue. This happens in both single card and crossfire mode. Certain games seem to like the card more then others, ex. BF4 not a single problem, SC2 nothing but trouble in crossfire.

I haven't had any problems with mine yet, a few freezes due to a wonky PSU but thats it.

The R9 280x is a smidge above the regular 7970, it is a 7970 GHz edition. The R9 280x also became the Tahiti XTL chipset which to my knowledge was not really announced. I will admit I have no idea what the running changes were. The biggest difference between the two graphics cards is MSRP, with the 280x being a fair amount cheaper than its twin, the 7970. I've heard first hand accounts of the 280x performing marginally better than the 7970 GHZ edition, but I have no personal experience to back that up with. I know they cooperate with each other in crossfire if that says anything.

that actually helps out a lot, so I can crossfire a r9 with my 7950 and it should work?

I know you can crossfire the R9 280x with a 7970, or a 7990 for sure. But the 7950 I'm not sure of. I'll scour google a bit and see if I find anything.

So from what I see the 7950 is Crossfire compatible with the 280x. It seems that you need to overclock the 7950 into the 1GHZ range to get it's speed up closer to the 280x's. I saw a couple videos of it working on youtube and it seemed just fine, and there was a couple pictures and threads from various sites on google. I think you'd be just fine. thumb.gif

Seems like it would be more cost effective to just buy a used 7950. I doubt you'll get much if ANY performance gain over crossfiring a 280x and 7950 over crossfiring two 7950's. 280x will render and then wait for the 7950 to render. Who knows. . Might even cause more micro stutter. I know people complain about micro stutter but I honestly don't see that issue with my 7950's.

you are right, for now though, I'm just going to stick with my 7950. get it cooler than it is now and that's it.

I got the replacement 280x today, and oh my god this video card is not even in the same universe as the Club3d card was. This thing is built like a tank. I bet it weighs a couple pounds. The cooler frame and everything is made out of metal. It is extremely sturdy, and I am so pleased to own it. It idles at the lowest temperature I've ever seen reported on my rig, 30c. Also unlike the previous Club3d card, this one has absolutely zero coil whine, none!






thumb.gifbiggrin.gif I will post back answering any questions, and updating as I feel it's warranted. (Especially if it only lasts 45 minutes again..)

*Edit* I played 2 full maps of Battlefield 3 which is over an hour, and it still lives! I'm impressed Powercolor! Haha.
