I'm having an issue with a rig I'm building. I have followed the hashcat wiki to build Ubuntu server 14.04.4 and install the ATI 14.301.1001 driver. The driver installs fine and I can get up to 4 cards working with hashcat without issue. Interestingly, amdconfig --adapters=all --odgt returns temperatures for 2 cards but fails on the other two. Other than this oddity I have tested the rig with 4 cards cracking hashes for a few hours without any issues. As soon as I add another card, the system no longer boots. It looks like it hangs while starting X - so I'm thinking it's failing while loading the driver.
Specs:
- 6x7970 (4x MSI twinfrozr 2xreference boards)
- sempron 145
- gigabyte ga 990fx ud3
- 1300w risewell psu
- 750w evga psu
- 4gb ram
- 6x 1 to 16x non powered risers
Any thoughts on what the issue might be? Resources for this seem scarce and I've been beating my head against this for a day now.
Any help is much appreciated.
To add:
- tried mixing the cards around and testing each card individually and they all work fine. So it doesn't appear to be a hardware issue.
