R9 390 Overclocking Help

[IanwithanE]

Im well aware that the r9 390 is a terrible card to overclock and the Strix r9 390 doesnt cool the vrm's very well, but i have 2 questions about my overclock.

 

I managed to get my r9 390 strix to 1125mhz core with +10% voltage
Thats not weird

I kept upping the memory clock to see how far it would go and it finally got to 1950Mhz and was fine, but i was seeing no gains in performance. It either was not actually applying the clock i was setting (sometimes when an overclock fails it reverts to defaults, but it claims it was running at 1950 mhz) or i got the best memory in the history of the world for r9 390's, but it just didn't make a difference. My first question is what is happening there?

Secondly, would water cooling the card with something like the Kraken G12 (i already have a AIO just sitting and collecting dust) provide a better overclock? Would putting heat sinks directly on the vrm's provide a better overclock? I've watched a couple videos with conflicting results so what can i do, if anything, to up the clock on this card?

Not all aplications will see a boost in performance from a memory overclock, though with AMD memory overclocking is typically just as important as core overclocks. Its possible your card is not bottlenecked by its memory.

 

If you stick your water cooler on, it certainly will drop your temps but you won't get much more of an oveclock out of it. You can lower its power consumption if you cool it enough, but that is about it.
