Powercolor turboduo R9 280X artifacting

ookii237 · Sep 25, 2014

I purchased a used Powercolor turboduo R9 280X and it get some artifacting in games and on videos. The artifacting only happens in a small rectangle on a fixed spot on the screen.

It looks like a rectangle filled with smaller rectangles with distorted pixels in the smaller rectangles. It isn't always there but once it appears it wont go away till you turn on the game or video.

I was thinking it is a bad memory chip and have tried to test the gpu memory with no real verdict on weather or not the memory is bad. I've used Video Memory Stress test and OCCT.

The artifacts don't seem to appear in bechmarking like Valley or 3DMark. Furmark runs fine with no artifacts.

Just wanted to know if anyone has experienced this problem and knows whats causing it. I am going to reload my system soon to see if windows is causing it.

Thanks

If still there, might try a different PSU, if still there might be the GPU itself (which may be why it was for sale)

Still happening here is a clip of what is happening.

InvestigativeSpleen :

do not buy AMD/radeon. r9 known issue is a DIRECT X problem caused by the old rereales chips not having hardware support for the new DX changes and AMD will not be redoing the old 7900 series drivers for a fix. Took me weeks and lots of research and a couple of tech support dudes with loose lips tunes me in. DO NOT waste your time or money these chips appear only good on specs and real world results are unacceptable running new windows versions due to massive issues and returns of r9 series cards. The suppliers like gigabyte, asus are absolutly spewing at AMD and there is a lot of talk about some brands dropping thier AMD offerings due to brand damage cause by this AMD dash for cash releasing old chips they knew would not handle new DX changes and OS changes. SHOULD BE SOLD AS ORIGINAL CHIP and only as discontinued stock. DO NOT WASTE YOUR TIME RETURN ANY r9's and start again with the reliable Nvidia offerings.

That sounds like nonsense to me InvestigativeSpleen. NVidia, AMD, Intel, IBM, ARM all chip manufacturers reuse chip architecture.

I have solved quite a few issues for people with the same card saying the same thing, the fix is to reduce the clock speed and memory speed on the card. Start with a 2-3% decrease for both clock speeds. see if issue is fixed, still happens add another 2 or 3%, I would do this until about the 10-15% mark in speeds.

If it's doing this, it's probably defective, reducing the freqs/speeds is simply masking the problem - it should run as advertised
