RX 560 unlocking shaders in BIOS.

[Hand Solo]

These cards originally had 1024 shaders with 16 compute units. This one is showing 896 shaders, so it has 2 compute units disabled. I read that they used to disable them in the BIOS, and that modding your BIOS could potentially enable the other 2 compute units.

A while back I spent a fair bit of time messing around with some tools, trying to mod this one. I was unsuccessful. I also compared my BIOS to other peoples' BIOSes, both ones that failed and ones that succeeded. From what I can tell, all of the cards that couldn't be modded were lacking a certain entry in the BIOS. So have the chips themselves been physically modded in these cards?

It's been many years since they started fusing them off.

This is going back in my memory quite a bit.... The 560D had 896 shaders, but it was a bios lock. I would flash the bios to an identical card that is not a D model and it should work

you will find the most information if you look up unlocking 560D

Well, it looks like I wasted my time. Thank you for your answers!
