Hello to all.
I just upgraded my machine to 2x7970 .Both of them is Gigabyte, one is GHz edition and the 2nd one is standard. The problem is when I run some test etc my computer freeze. I try with standard clock,overclocked blablabla...same....

Maybe some help ?
BTW I use Catalyst 12.8 (in windows 7 64bit and in linux ubuntu 64bit too).

Try reducing your -n to see if it helps avoiding the crashes. Also, when does it crash? What was the command line and algorithm used? Other than that make sure that you have a good enough PSU for your 2 cards. For Windows, there is also a patch that could help:

PSU for GHz edition I use chieftec 600w and for standard edit.use separetely PSU 550w. Patch allready in my registry ,.

comm.line and algo.: oclHashcat-plus64.exe -m 2500 -n 32 --gpu-loops 4096 -a 3 -1 abcdefghijklmnopqrstuv xxxxx.hccap ?l?l?l?l?l?l?l?l

Same command line as for single GPU.

Crash after this:

Now playing with -n command. with 1 not crash, but it's slow. with -n 8 crash...

remove --gpu-loops 4096 and see what happens.

I did. Crash again. I will try now to lower the -n to 16 or 8. At 8 was stable last time.

...strange...after 5sec with -n 8 crash too!

probably a defective card. I suspect the GHz edition. Try testing both cards separately.

hmmm...maybe...I will try that too, but never had a problem with Gigabyte brand!

..before I had with single card, with HD 7970 standard ed.,162k/s on WPA2 crack, now with both card had the same score.

The standard edit.of 7970 allready tested before, and qork great,without any crashes, and now I tested 7970 GHz edit. separately and the result is with following command line:
oclHashcat-plus64.exe -m 2500 -n 32 --gpu-loops 4096 -a 3 -1 abcdefghijklmnopqrstuv xxxxx.hccap ?l?l?l?l?l?l?l?l
