      My guess is that they are building drivers for faster gaming frame rates, not mining.

      But what do I know? lol

      They still should try not to wreck their OpenCL compiler in the process.

        Will these updates work with the Linux version?

          Do you mean the miner software itself?

          You can always build the latest miner in Linux by yourself much easier than in Windows. Anyway, I will upload my own general prebuilt package as well.

                Okay. I have built 5.0.1 and downloaded 5.1.dev from nicehash. Both versions of the software give me the invalid nonce - HW error. I am able to run neogpuminer 3.7.8 with no issues.

                The os is Ubuntu 14.04.1 LTS. Had driver 14.301.1001 but uninstalled it and added 14.20 with the same results. Any ideas on best way to proceed?

                  Did you clean the bin file inside the sgminer directory after downgrading to 14.20?

                  Furthermore, if you can downgrade even more, Catalyst version 14.4 is worth trying. By the way, I have sgminer running with 14.6beta2. What was the exact version of 14.20?

                    Yes, I have cleaned the bins. Are you running linux as an OS?

                    These are my test settings:

                    export GPU_MAX_ALLOC_PERCENT=100
                    export GPU_USE_SYNC_OBJECTS=1
                    cd /home/sktpoolsworker01/sgminer-5.1.dev
                    ./sgminer -v -k neoscrypt --no-extranonce --auto-fan -D -u test -p test -o stratum+tcp://sktpools.com:19327

                      Yes. Linux as the primary OS.

                      This is mostly driver related. But anyway, can you play with these parameters and see if they help?

                        I am going to rebuild the machine. So it was AMD Catalyst 14.6 beta and ADL_SDK 6 or 7 for the miner sgminer build? Also the latest AMD APP SDK?

                          AMD Catalyst 14.4 or 14.6beta2 with ADL_SDK 6. I think the latest is not supported.
