Hi guys,

I successfully unlocked my Sapphire R9 290 BF4 Edition into a R9 290X, the shaders unlocked with GPU at 1000Mhz aswell in GPU-z but when I use it for a benchmark or a game the card is stuck in PCI-e 1x 1.1 and GPU Core at 300 Mhz... It seems to stay in idle mode.

Does anyone knows why this could do this ?

It happens only with 290x bios.

I tryed PT1 bios and it works but my card seems not stable and stuck at 1000MHz, can't go lower or higher.

I assume this is not a driver issue since I tested the card in another computer that was brand new.

Thanks guys.
