clEnqueueNDRangeKernel(-4) when running multiple gpus

[DavBE]

Hi,

Using this command line :
genoil.exe -c equihash.usa.nicehash.com:3357 -u btcaddress.worker -p x -i 20 -w 64 -P 0 -g 0 -k zec
the miner work fine.

But when using this one :
genoil.exe -c equihash.usa.nicehash.com:3357 -u btcaddress.worker -p x -i 20 -w 64 -P 0 -g 0 1 2 3 -k zec
i get the following errors :
zec-sa#3clEnqueueNDRangeKernel(-4) z1e5c:-0s0a:#303 gpu#3: Mining thread quitc lEnqueueNDRangeKernel(-4) z1e5c:-0s0a:#323 gpu#0: Mining thread quitc lEnqueueNDRangeKernel(-4) 15:00:33 gpu#2: Mining thread quit

and only one gpu reports mining stats. I have 2 HD7970 and 2 R9 280x running on this rig (Windows 7 64bits).

Any idea ?

Try this, maybe help you:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

genoil.exe -c equihash.usa.nicehash.com:3357 -u btcaddress.worker -p x -i 20 -w 64 -P 0 -g 0 -k zec

or

genoil.exe -c equihash.usa.nicehash.com:3357 -u btcaddress.worker -p x -i 20 -w 64 -P 0 -g 0 -k zec zec

or

genoil.exe -c equihash.usa.nicehash.com:3357 -u btcaddress.worker -p x -i 20 -w 64 -P 1 -g 0 -k zec
