hashcat Forum

i am using :
i3 2nd gen CPU
AMD Radeon HD 6470M

trying to do WPA2 hash bruteforce but

ERROR: ERROR: clGetDeviceIDs() -1

error stops it
how to solve it ??

If this is on XP you are lost. AMD removed support for OpenCL. You have to upgrade to Win7.

i am on win7 64 bit pro

install latest drivers. If this doesn't work, your chip is not supported. Mobile GPUs are often unsupported.
