      Tried lizhi’s new 3.7.7b with Radeon HD 6950

      -g 2 -w 64 -I 14 = 4.45 KHS. WU = 4.1 2.04 KHS at the pool. Extremely unstable. Screen flickering… Had a hard time killing it.

      -g 2 -w 64 -I 12 = 3.2 KHS. WU = 3.7. 2.99 KHS at the pool… Laggy, but stable (normal for mining).

      -g 1 -w 64 -I 12 = 3.2 KHS. WU = 3.7. 3.1 KHS at the pool. Mining

      -g 1 -w 48 -I 12 = GPU failure.

      -g 1 -w 32 -I 12 = 3.92 KHS. WU = 4.3. 3.3 KHS at the pool. Mining.

      -g 2 -w 32 -I 12 = 4.0 KHS. WU = 1.8. 2.6 KHS at the pool. Mining.

      -g 1 -w 32 -I 10 = 1.9 KHS. WU - 1.9. 1.75KHS at the pool. Almost usable as a PC while mining.

      -g 1 -w 24 -I 12 = GPU failure.

      -g 1 -w 16 -I 12 = 2.8 KHS. WU = 2.5. 3.0 KHS at the pool. Mining.

      Slightly better numbers, but not significantly. Stability seems a little better.

        cgminer 3.7.7b in http://www.ftc-c.com/pack/testnet.rar , It had fixed some problem.

        I’ve been using this for more than 24 hours without issue and no -T option either so it seems it is a good version Thank you

              What do you mean? The accepted shares amount? I am getting around 500k a day at 390 khs

                It froze again at this post’s time. Back to the -T option

                  I have left the latest version on overnight, I am getting am 41khash/sec on my nvidia with compute 2.0. I think that is pretty good for an older card. I can get another 7khash/sec if the cpu miner is running on 3 threads. I get 12khash/sec with the cpuminer if I run on 4 threads and mine darkcoin with the gpu.

                  I still am getting higher cpu usage when the gpu miner is running. I think it runs a lot more stable if I leave one cpu thread free. This might be an area for improving stability in the next version. I think that cgminer right makes everything else run slow because it is using cpu and has a higher priority.

                  Another option for improvement would be to increase how much cpu that cg miner uses, but just add a setting for how many cpu threads to use. It might run better if one cpu thread is dedicated to all other programs, while cgminer is hashing and controlling the gpu with the other cpu threads.

                  (My start options are: -I 11 -w32 -g 2 )

                      370k shares 24hours at 284khs, compares almost equal to your shares

                      single best share 13.2M, getting like 2-3 +10M shares a day, is it too much luck?

                      WU value is out of control, its showing what ever it likes

                        I’ve pointed some mining power to theblocksfactory on the PXC pool :-)

                            Yep :-)

                            But just moved most of it over to p2pool

                              Having the best luck as mentioned earlier by using bin files created with 13.11 and then installing the 14.X drivers. Seems that the R9 290 doesn’t understand the -g 2 option without the newer drivers installed (makes a big difference in hash rate for the R9 290). I’ve got my 7950’s hashing at 85Kh/s and my R9 290 (hynix) at 111Kh/s. using -g 2, -I 13 (7950’s), 14 (r9 290) and -w 32 for both. My 7950’s are OC’d, the 290 is running stock clocks and undervolted. Running 3.7.7b.

                                How did you undervolt the 290 ?

                                  Where is the lastest cgminer source available?

                                  thanks,

                                    Hi,

                                    did anybody get it run on a iMAC?

                                    I get only about 1-2 KH/s and system is very unusable. My iMAC is late 2011, with AMD HD6770M.

                                    I got “normal” hashrates for scrypt, keccak and so on…

                                    ./cgminer --neoscrypt -I 8 -o urltotheblocksfactory -u user -p passwort

                                    build with latest source from https://github.com/vehre/neo-gpuminer

                                    regards,

                                      It isn’t a Mac related problem, it’s VLIW5/VLIW4 architecture. If a kernel isn’t vectorised, it performs terrible. That’s what you see. If it is, the performance is excellent. For example, Myriad-Groestl delivers 11.5MH/s for HD5870 (Scrypt 400KH/s), 15MH/s for HD6970 (Scrypt 500KH/s), 17MH/s for R9 280X (Scrypt 700KH/s). I hope the situation will change soon.

                                        I’m using MSI Afterburner. Most of mine seem to run pretty stable at -62 with stock clocks.

                                          Hi all, with a GTX780 i can get cgminer to start running 3.7.1 but 3.7.7b i get the following error:

                                          Failed to init GPU thread 0, disabling device 0

                                          Restarting the GPU from the menu will not fix this.

                                          Try restarting cgminer.

                                          i tried replacing the file as mentioned on the 1st page.

                                          Is it an issue with having an NVIDIA GTX780?

                                          Thanks

                                            the error is often related to a missing or wrong .cl file.

                                            you need the file neoscrypt140909.cl in the directory you use as working directory, when you start cgminer. after compile the file is in the directory the new made cgminer binary resides in.

                                            I have a NVIDIA GTX 750Ti and 3.7.7b is working fie for me
