Speed On hd5970,IGHASHGPU--4682M, hashcat--1704M
I have Catalyst 10.7 and ATI Stream SDK v2.1.
When I run oclHashcat , it crashed , I have to specified parameter -d 1 so that it can works. But it works only 1 gpu.

IGHASHGPU has no problem.

See the screenshot:
2nd gpu is not supported in 5970, see here:

Thank you !
How can I improve the performance except -n 80? I bought this hd5970 to use hashcat today!

ATI needs to fix opencl runtime
