The XFX r9 390 isn't hitting the overclock speeds.
The XFX r9 390 isn't hitting the overclock speeds.
I chose to boost my card's speed, but I'm facing issues with increasing the voltage. I reached 1125mhz core and 1625mhz memory without problems, staying cool and avoiding crashes. At 1175mhz I noticed some big artifacts, so I raised the voltage by 25 mV, which stabilized the card but hurt performance. The benchmarks now show the GPU only running around 700 mhz. I'm unsure what to do next.

I've faced a similar issue too, even with an 960, but anyway. It only happened when the card hit its limit. Once the downcloking occurred, I had to restart the PC and run it with slower clock/memory speeds.
It looks like the card can't exceed a certain threshold and just downclocks until a system restart happens.
My suggestion would be to slightly lower the card's speed, restart the system, and then do a stress test again.

I've faced a similar issue too, even with an 960 chipset, but it was still the case. I noticed it only occurred when the card hit its maximum limit. Once the system was unclogged, I had to restart the PC and run it at lower clock and memory speeds.
It looks like the card can't exceed a certain threshold and then automatically downclocks until a restart happens.
My thought would be to slightly reduce the card's speed, restart the system, and then perform a stress test again.
But that didn't help.
It seems that increasing the voltage on the card actually reduces its clock speed.
