![]() This means cgminer isn’t capable of handling the latest series of graphics cards. Specifically, they’ve updated their Overdrive engine from version 5 to 6 With their Hawaii architecture, AMD updated some things for the R9 290/290X. If you can get that far, you’ll quickly find that cgminer will crash upon exit (use version 3.7 and earlier if you want GPU support as its been dropped), and lock the GPU resource (fans will continue running for example) until reboot. Someone was also nice enough to provide binaries for Ubuntu. ![]() More information on such can be found here. The latest beta drivers ( 13.12)need to be patched to keep them from crashing and failing entirely. The fact that cgminer no longer supports GPU’s compounds the issue, but it is a fixable problem. It seems to be fairly common for the latest drivers to cause issues on both Linux and Windows. Picked up a couple of the newer R9 290s to add to my mining rig recently and encountered a number of problems with the latest AMD/ATI drivers as well as cgminer.
