ATI OpenCL support up to 4GPUs in Win7?

post #1 of 6
Thread Starter 
Running Win7 SP1 x64.
Installed Catalyst 11.5 and sdk 2.4.

I have 5 GPUs on the motherboard, all 5830s. One GPU is on a 1x slot.
When I open GPU-Z, it says error detected in OpenCL, and ask me to reinstall OpenCL.
Went ahead and reinstalled both driver and the sdk, but still the same error when GPU-Z opens.
When I removed 1 GPU, (so now has 4 GPUs), the error goes away.
The 1x slot is still occupied by a GPU, so I can rule out the problem caused by it.

Is there a limit on the number of GPUs that can run OpenCL?

The max for Cross-fire, as well as SLI is 4 video cards.

Linux can support 8. Try that. Windows can only support 4 max. Good luck mining!

No crossfire, just individual cards.

what are you going to do with 5 individual 5830s? Quad-fire em and take the last one and stick it in a folding farm { OR GIVE IT TO ME}XD and windows based OpenCL probably only takes on 4 GPUs, but im not sure, im not an OpenCL guy
