XFX 7990 GPU 1 not overclockable

Discussion created by krentekut on Nov 30, 2015

Hello People,

I just got a XFX R7990 (tripple slot) and ofcourse I immediatelly want to check what the card is capable of (yes it's awesome). But when I try to overclock the GPU, GPU 1 won't go any higher then 950 MHz (base clock, in MSI afterburner I typed 1100 and it acknowledged it, but GPU 1 doesn't clock to 1100). GPU 2 is overclockable to 1100 MHz and works fine but GPU 1 just won't seem to go higher. Temps are fine, they aren't going any higher then 70. I've overclocked lots of times so I really doubt it's my undoing. I tried googling this issue but I can't seem to get any results. I've thought about flashing the card but I'm not quite sure yet, mainly because  I've never done it before. Tips would be much apprecicated!

If you have questions for me don't hessitate to ask:)
