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: http://www.xtremesystems.org/forums/showthread.php?292163-5970-useless-now
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!
