Arch: 64bit
OS: Linux
GPU: 7 x AMD Sapphire 7970 HD
oclHashcat: 1.31
Catalyst: fglrx 14.30.4

The run starts fine. Status looks good. At some point one of the GPU's starts to show 99% Util and 0 H/s, Progress gets stuck at 99% and the job never finishes because it seems to be waiting for the last GPU to finish. I'm already skipping one GPU due to this issue, and now a second is acting up.

Command for testing, run should complete in about 25 min. Notice I'm already skipping GPU 6 due to the same issue.

oclHashcat64.bin --gpu-devices=1,2,3,4,5,7 --gpu-temp-retain=65 -m 0 notahash -a 3 -1 ?l?u?s?d ?1?1?1?1?1?1?1

Three status are shown below
1. Beginning, all good
2. GPU 4 wedged, other GPUs still working at progress 7%
3. GPU 4 wedged, other GPUs finished with work, progress 99%, will never finish.

Thanks for pointing out the new version mastercracker. Just tried oclhashcat v1.32 and get the same result.

Here's a status just before and then wedged

I first had the problem with GPU 6, and now having the same problem with GPU 4. Still not sure if a hardware problem or software bug. They seem to work initially then get wedged a few minutes into a run.

I use the --gpu-devices switch to list the cards that aren't getting wedged which is now 1,2,3,5,7

At the start of a run you can see this as below. It's a little confusing in the status output which lists them sequentially without indicating the skips.

oclHashcat v1.32 starting...

Device #1: Tahiti, 2876MB, 925Mhz, 32MCU
Device #2: Tahiti, 3022MB, 925Mhz, 32MCU
Device #3: Tahiti, 3022MB, 925Mhz, 32MCU
Device #4: skipped by user
Device #5: Tahiti, 3022MB, 925Mhz, 32MCU
Device #6: skipped by user
Device #7: Tahiti, 3022MB, 925Mhz, 32MCU

@m0t0

It seems your GPUs are dying...at least from what you've described so far. Have you tried to isolate GPU 4 and 6 and run oclHashcat only with those 2?
Or can you test those two Cards in a seperate Machine? This should quickly clarifiy if its the Hardware thats dying or if its oclHashcat.

Kind Regards

Thanks TheDarkOne, good idea. I just ran the test isolating GPU 4 and 6 and they completed without issue.

One more thing I've noticed about this issue is that once it occurs job control is lost. I cannot [q]uit and even trying to sudo kill -9 the pid just results in a defunct process.

Also it can be too high clocks for gpu/ram or too low ram clock, also PSU problems can behave like that. What I would try is just to lower clocks a bit. Besides on your card's you should get a bit higher MH/s if they are on stock clocks (1000MHz?) so maybe cooling problems occur and they start throttling clocks and this sometimes is the reason for ASIC hang.

Thanks @ati6990, no risers. Will review motherboard settings.
