      This SGminer crashes immediately with no error message.

      14.9 drivers are installed, and 14.6 dll’s are in the folder, and it does not matter if the bins from a working version of SGminer are in the folder or not.

      Is this expected behavior?

      Thank you very much for testing the miner.

      Definitely that is not the expected behavior.

      I should investigate the issue and I’ll provide an update for this soon.

        CGminer 3.7.8 also immediately crashes with no errors, running 14.9 drivers.

          I heard this happens with 14.12, you sure you’re not running that?

            OK. I have been investigating this issue so far with little success. I am running the program with 14.9 drivers here with no problem. However, I could get the same problem (crashing with no errors) on another PC. Anyway, I am going to turn on debugging and trace the problem. Also, I am going to test different driver versions.

            By the way, I just do not like Windows (I should say I hate Windows). On Linux, driver changing is a breeze, but on Windows it becomes a pain. I myself have used Display Driver Uninstaller and several other tools to get over the stale files. Mixing files from different versions might be your problem as well. So it is worth trying DDU. It is very simple and straight forward.

            Thank you very much for your patience and your efforts for testing the software.

              Absolutely 100% positive that I’m running 14.9 and not 14.12.

                After almost one day of investigation, the problem turned out to be from cross-compiling.

                Now both of the miners have been tested with AMD drivers v14.4 and above.

                I have uploaded the newly built software and have updated the links in the first post.

                Thanks

                  The Omega drivers (14.12) are pretty bad, at least for me on Linux.

                    Definitely agreed. I do not know what AMD is doing.

                      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.

                              So I just need to build the latest sgminer 5.0.1 from github. Will the latest improvements be in github?

                                  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.
