Sapphire Nitro R9390
Drivers are current; have tried with Radeon Settings, MSI AB, Sapphire TRIXX, still get fluctuations from 150-1500 mem clock speeds which causes unrecoverable crashes.
I have changed mem clocks and they are fine at around 300 (still spiking, from 150 to 300, but it's not enough to make my system crash. It happens when watching videos, as well as with League of Legends, have not seen it on my other games yet - I am assuming it is to do with 2D settings. Any help would be greatly appreciated.
1500 is the stock mem clock speed, btw, no overclock (though with overclock being stable at 1600 aside from videos, since it fluctuates 150-1600 same as 1500).
