How to resolve this error? "ERROR: clGetDeviceIDs() -1"


I am using oclHashcat v1.35
Catalyst version 14.9
Video card is AMD Radeon HD 6350

(Also have built-in ATI Radeon HD 3200)

Not helpful. I'm using Windows. Pretty sure I have the right driver, since this link says use Catalyst 14.9: https://hashcat.net/oclhashcat/

The error means that hashcat cannot find a compatible GPU. Okay, fine. The HD3200 is not compatible, but the HD6350 is.

So, I guess the question I should be asking is:

How do I tell oclHashcat to use the HD 6350 video card???

Try using either -d 1 or -d 2 in your command or blacklist the onboard gpu

ie .
-d, --gpu-devices=STR Devices to use, separate with comma

I'm not sure how to use the command, all I'm getting is:

Usage: oclHashcat64 [options]... hash|hashfile|hccapfile [dictionary|mask|directory]...

Try --help for more help.

Just add either -d1 or -d2 to your command your currently trying to execute.

To simplify it a little just run a benchmark for now.

oclHashcat64.exe -b -m 0 -d1
or
oclHashcat64.exe -b -m 0 -d2

oclHashcat is just crashing now.

Hm, tried oclHashcat v1.36. It's also crashing.

I tried Catalyst 14.12, and oclHashcat is still crashing. My guess is that I have to use the HD6350 card as my current display then completely disable the HD3200 in Device Manager. Otherwise, I'm clueless.
