crossfire strix r9 380 4gb issues

[Pibi86]

hello!

I have recently bought a new strix r9 380 for crossfireing with my exact copy of another r9 380 that I have been running with awesome results.

my system: msi 970 gaming mobo
16 gb 1330hz ram
550w psu
2x strix r9 380 gpu
amd 8320e cpu
windows 10 x64

I installed the gpu's as instructed on many forums; uninstalled all drivers for gpu, placed new gpu in first pci-e slot-turned on and updated all the drivers, replaced new gpu with old gpu-updated drivers, placed both gpu's in mobo in pcie x16 slot.

hey presto the 2nd gpu appeared in the board explorer and device manager in the os, also was synched in gputweakII and showing stats for both gpu's. AWESOME as my previous attempt had failed due to a DOA card.

turned off pc, and it has never worked again.

so read a few forums and they said that the crossfire is buggy as s##t and if I was having issue with it it would be better to re-start the system and start from scratch.

did that (5hrs!!!)

repeated step 1... nothing.

updated bios to newest version... nothing

(p.s, the power is connected and the led is on and the fans work, the new gpu is not dead as I am using it as I write)


HELP!!! have I missed something am I being stupid, or is just difficult to keep stable?

ok so now both gpu's are showing up on the Os device manager and on the mobo explorer
but now I am unable to open up catalys control center or the gpu tweakII

I get this error:

No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD appropriate for your AMD hardware.

and now it crashed when running arma3 and I'm back to square one

after repeating step one I am now back at the gpu's appering on the board explorer and device manager,

when I open catalyst control center I get this again

I get this error:

No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD appropriate for your AMD hardware.


I have re-installed catalyst with mixed results:

gpus appear on catalyst but there is no crossfire option?

catalyst decides its not going to open anymore the pc crashes and I'm back at square one again

I don't really know if this has fixed it but this is what I am doing with it now:

I uninstalled catalyst control center and gputweak2-

it seems to be running from the system itself???

I ran a few games (overwatch-arma3-fallout4)

it seems to be working

arma3- high to ultra-a steady 45-50 fps even with 2000 draw distance

fallout4- 50-55fpsat ultra settings

overwatch- 50+fps on epic settings

????


it works for now I suppose, any input from anyone??

I bought a new GeForce 980

great community so far, thanks guys (yes I'm being sarcastic)

Did you have Catalyst or Crimson drivers? Catalyst Control Center is the old AMD drivers, Crimson are the new ones.
