Hi, 5970 user here. Lost my 2nd gpu with latest drivers

-MSI afterburner shows 2nd gpu is always at idle speeds (150/300).

-Playing a game that supports crossfire shows 0% load on the 2nd card.

-GTA V says i have 1gb vram, where it previously said i had 2.

-FPS are somewhat halved in some games.


I tried reinstalling drivers, using DDU in safe mode, tried beta (15.11) drivers, etc to no avail. I believe this is a bug either on amd end or my system. Rolling back to 15.7 solved this issue for me.


My specs are:

Gigabyte G1 Sniper.B5

Intel i5 4440

XFX 5970 black edition (w/latest vBIOS)

Corsair 8 gb ram

Windows 7 64 bit


The HD 5970 is not a very popular card nowadays, i only found one link to a discussion about a similar issue here:

Thought i just report this issue so maybe AMD can investigate it. I'm concerned about my card working with future driver updates, especially when/if fallout 4 optimized drivers roll out. Thanks in advance!
