R9 295X2 crossfire only using 1 gpu

[ScottWood]

Hello,

So i recently aquired a 2nd 295x2 and cant set it up for some reason not matter what i run that being a game or a benchmark it just dont uses more then 1 of the 4 gpus however with 1 card in it will use 2 of the gpus.

Running firestrike will crash the system sometimes and i cant figure out why and running any game works fine apart from its only on 1 gpu.

Any suggestions?

Thanks

I would assume 4-way Crossfire is as glitchy and unpleasant as 4-way SLI, so I wouldn't hope for much. Is your PSU okay delivering that much power to multiple GPUs at once? Those cards are monsters and need ridiculous power. Are both cards being detected in windows?

Yeah it should be fine loads other have done it with 1600w or less for some, both being detected in windows so im at a loss, doing a full reinstall of the drivers now...
