hello, i have 2x6990 with right amount of power (2xpsu combined with add2psu for a total of 1950 w   )

but mining with cgminer it detect only 3 cores of 4 total cores (2 cores for each card)

the error that prompt is


ADL found less devices than opencl!

Use the gpu map feature to reliably map OpenCL to ADL

WARNING: Number of OpenCL and ADL devices did not match!

i'm on windows 8 x64 , and on system devices are correctly detected 4 cores of cards....

driver is 13.1

since with 13.4 cgminer went to crash from command line

rebooting and removing again and adding again the drivers through control panel ---> installed devices it worked and also cgminer found 4/4 cores.


however mining with 4/4 cores leads to another software error

(since i saw through power consumtion meter that with 4/4 consumption is almost 1.000 w , i now have 1200+750 w psus so it is not possible that power is now enough)

it seems that the amd driver goes to crash . atikmpag.sys is the responsable.

currently i have 8 gb ram ddr 3.

i don't know what it cause that error....

edit: the system goes to crash also with 3 cores. it seems that the driver is not able to manage computing of more than 2 cores....
