Problems with Sapphire AMD R9 270x 2gb artifacting

I purchased this card from eBay a few years ago for pretty cheap. About a year ago I started getting artifacts in the form of spikes, however they were very minor and I just ignored them, assuming it was some sort of bug. Recently, however, the artifacts have been getting worse. I believe the source of the problems is in the video RAM, because I am getting memory spikes (black spikes emitting from random objects). I ran the Windows Memory Diagnostic tool, as well as video memory stress test, and both returned zero errors. This is definitely not an overheating issue, as I play with my fan speed set to 80%, and the peak temperature my card is at while the artifacts are occurring is about 55 Celsius. I have posted a screenshot of video memory stress test as well as a screenshot of a very large memory spike in Grand Theft Auto V. What else should I try to fix this? Also, if both tests resulted in zero errors, does that mean the problem could be from somewhere else?

    Well assuming the artifacting isn't caused by a software issue, say old or corrupted video drivers. Then there is usually not much that can be done about aftifacting besides increasing core voltage or lowering core clocks. You can do this with software like msi afterburner, try taking 50mhz or so off the core clocks or increase the core voltage a touch and see if there is still artifacting. I'm doubtful the VRAM is causing it but you can also reduce VRAM clock speeds in afterburner as well, if the memory is unstable reducing the clocks should help.
  2. It's either A. damage due to heavy OCing, or the more likely option; memory bottlenecking, turn down AA settings all the way to x4, and lower shadows.

    Question from lukectn : "AMD R9 270x artifacting"

    I have been getting some bad artifacting lately in nearly every game including GTA V, and CSGO.

    My specs are:
    -AMD FX-6300 cpu
    -MSI 970 Gaming mb
    -Sapphire AMD R9 270x 2gb gpu
    -Hitachi hua721010kla330 7200rpm 1tb hdd
    -G.Skill Sniper 8gb ddr3 ram
    -EVGA 500B psu

    I have tried increasing fan speed, and I dont think overheating is an issue because I ran GTA V for half an hour on high settings and the peak temperature it hit was 41°C.

    I also underclocked it from the base clock by 50 MHz, and saw a lot less artifacting, but it was still present.

    Does this mean I need to replace the graphics card? How much longer do you think it can go before dying, because I dont have enough money for a new one at the moment. It is fairly old so im not too surprised if its nearing the end of its life, as I purchased it used from ebay. Is there anything else I should try?

    I underclocked both core and memory clocks, as well as increase the power usage by +20% (the most it would let me do in AMD Overdrive), and it seemed to do the trick. I've been playing for a few hours now and haven't noticed any artifacting at all. Thanks!
  5. At stock settings that's awfully strange, never noticed any voltage bottlenecking with AMD's 2xx cards out of the box.

    Oh well, good to hear you solved it. :)
