AMD GCN GPU Disabled Stream Processors Unlockable with Software
Interesting news, it seems that if you own a recent GCN based Pro series GPUs from AMD (Hawaii Pro / Fury Pro / Tonga Pro / etc) is now possible to unlock, at least some of the disabled parts on the GPU.
Over at the OCN forums a user called tx12 released a little utility called CUinfo and this tool can be used to read information about active and disabled CU units in Hawaii, Tonga and Fiji. Basically the tool reads out the GPU core configuration, which can be altered and then flashed back into the BIOS with another tool and some modification. The current status of the tool is that it only reads out info, and you will have to edit and re-flash the BIOS yourself.
Cards like R9 Fury non-X, R9 390, R9 285 could be enabled with more CUs, I say COULD, as there are two methods used by AMD, laser cuts (prevents this from working at all) and through firmware, which would be this methodology.
Be warned though, GPUs are binned, defective CUs could be disabled for a reason, if you enable them ... who knows that will happen. Basically you will be gambling with your graphics card.

Somewhat similar to the infamous 6950 and 6970 thing, which sometimes worked, but later they used binned chips and it was no longer possible to unlock them.
Wouldn't be surprised if there was only a minor number of unlocks.

Yeah I did that with my two 6950's didnt seem to help much though with my cards.
Be interesting to see what happens when peoples start trying this.

Anyone with Tonga Pro tried to unlock Tonga XT? Card exist in mobile, maybe you'll end up with unique desktop GPU.

Interesting might give this a try when i get home i have the R9 290 but it's one of the first cards with custom cooling from MSI kinda interested if i can unlock the other processors, it's still plenty fast enough but hey, more the merrier!
