Hi all. i have a amd r9 290x reference. with a EK acetal and nickel block . max temp is 50c under load and as low as 22c idle uber mode , the cpu and motherboard are in the same loop so temps could be lower. What i would like to know is what is a stable overclock for a ref 290x with a water block. i play bf4 and mmo,s. and as im sure you all know bf4 hates overclocked gpu,s. i have tried in the past with the core voltage locked. 3dmark would be fine but bf4 would crash or bsod. my cpu is overclocked to 4.6ghz. manual volates on vcore, pll , vccsa and vtt currently. so i wish to finally overclock the gpu properly. i have msi AB latest version . Where shall i start what is a good profile ? i would like to use the same bios nothing massive just a profile that suits my setup.
