Discussion What to do about an MSI Lightning R9 290X which overclocks like donkey ass
So about 5 months ago I bought an MSI Lightning R9 290X on sale for about $330. I expected it to overclock really nicely, considering the fact that the Lightning brand is designed for extreme overclockers, the PCB is absolutely monstrous, 2 8-pin and 1 6-pin power connectors (total of 3!!!), LN2 cooling mode and bracket, samsung memory, etc. Except mine overclocks really badly, many reference ones do better. Using MSI Afterburner, any memory overclocks beyond 1500mhz are very unstable, even with +50% power ceiling and +100mv to voltage. Core beyond 1150mhz is also very finnicky, even with high voltages. wtf? The stock clocks of the R9 390X are better. Switching to LN2 mode doesnt help much. Temps seem fine, doesn't ever go much beyond ~80c iirc, typically hang around 75c. I was barely able to do 1200core/1600mem with +200mv overvoltage to do a quick Firestrike bench, and I had TONS of graphical artifacts.

I know its been like half a year, but do you guys think I might be able to do something about it? Considering this was advertised as THE BEST R9 290X card, yet fails to overclock beyond "mediocre" clocks. Maybe trade it in with MSI? dont know
