Flash the R9 290 to a R9 290x via a Simple BIOS Update


 

We came across a post on Hard Forum that shows the AMD R9 290 can be flashed to a full-fledged R9 290x. The blow posts and images are from Hard Forum:

Ok, I’ll probably get trolled by this thread as BS, but I read a few posts on other forums and someone posted they flashed their XFX R9 290 card to an Asus 290X bios and unlocked all their shaders. Well since I own two XFX 290 cards which I have already installed waterblocks and tested against my old TriSli on another forum. and with the bios switch on reference card, I thought what the hell! I’ll try it myself.

Here’s what I got.

(We have not tested this so try it at your own risk. Hardware 360)

Now I did have to flash the second card again as GPU-Z was showing an anomaly but after successful second flash it reported just like the first card. I have rebooted and restarted gpu-z many times and so far it has reported the same amount over and over again. I could be dreaming but this could very well be a reality that I now have a 290X in xfire!

So of course the next step is to do some testing…..here are my results so far. Both pre flash and post flash are clocked the same (1100Mhz/1300Mhz mem so far) What I have noticed though is under the Asus bios I had to up the voltage to 1.3 for it to run successfully at this speed under heaven benchmark, yet there was no voltage bump needed with the 290 bios.
