I've had the R9 280x Matrix Platinum for about a week now and what a week! All be it a great card from my previous 6950 in terms of performance, it's just been a pain in the rear. Artifacts and game crashes have been plauging me and I've been trying so many different things to try and fix it, or at least what I can do.
Now there are lot's of things to consider before one simply says "RMA". Firstly, I'd rather avoid RMA until I'm absolutely sure its a physical problem. Fact is it's a brand new card where the BIOS and GFX drivers haven't been around long enough to be considered totally stable, or it least that's my view.
Now I've been on Tom's hardware posting my problems there, you can check it out here - http://www.tomshardware.co.uk/answers/id-1849838/280x-issues.html - You can see my specs and more details on what I've done so far.
To sum up, I have found lowering the GPU and memory clocks helps but so far still get some artifacts. Does anyone else who has the same card experiencing the same problems? Can it be fixed with software or is this a faulty unit/first batch?
Any help would be great.
I think all 7970 cards (the 1050 clock class above) which is the same as 280x are having those issues.
true that the artifacts appear much lesser with newer drivers.
there is no problem with the core clock, you can even overclock it on gpu tweak.
apparently the problems are on the memory side, 3 problems;
1. standard gddr5 voltage is at 1.5v, while these later 7970s are on 1.6v. also memory clock higher than 6000 (1500) are hard to stabilize, especially when it is involving high power requirement games.
2. memory parts are always overheated (1.6v is high afterall), due to bad cooling system. the heatsink barely touching the ram chip.
3. amd powerplay; is trying to save power by auto-switching video memory between 2d & 3d clock, which causes screen flickers in both games and sometimes desktop.
you can see other's post for any temporary solution, but there is no fix for it yet.
my temporary solution using GPU tweak is:
1. set your 3D memory clock to 6268, using 1.520 voltage
this to reduce in game screen distortions, because it is either the chip cant handle high voltage or high speed memory clocks
2. set your 2D memory clock to 2400, same voltage
this should decrease the gap for 2d and 3d switches, and any 2d application "should" no longer causes flickers.
actually after writing all these, I just noticed your post in tom's hardware.
game crashes are usually caused by either wrong overclocking values or bad drivers.
if you leave those at stock clock and still crashing, it is mostlikely drivers problem (or card problem)
have you tried 13.11 beta 6 ?
my system crashes everytime I tried to install beta 6,
so I previously using 13.11 beta 1 and having no problem. but since I got ninja-trapped by upgrading to windows 8.1,
I decided to stick with 13.9 😞
sorry for the long post
