      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,

      freeapp

        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.

          How did you undervolt the 290 ?

          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

                What hash rate are you getting from your 750ti?

                  it’s ~ 40khash/sec at I= 13 no special tuning

                  Card takes 70 W of power

                    Found a little time to play with the newest cgminer, here are my findings, tested with many different settings. -w 16 produced the best khash of all tested. 8 to 512

                    3.7.7b config 2x R9 270 non X did work up to -I 15 but OS became unresponsive with little to no gain in hash rate, -I 13 best hash and feel for system.

                    also running minerd 22 CPU cores Solo locked to 23 CPU cores, GPU locked to CPU core 0… 37kh/s per GPU or 75kh/s for the pair.

                      Thanks, I also have R9 270.

                      Will start with your settings ;)

                        Seems I’m getting a bit more rejects with 3.7.7b than I was with 3.7.5, still within tolerance I believe, was a max of 22kh/s per card with 3.7.5, so I like the gain in k.

                          Howto

                          Getting started with gpuminer

                          • Linux: Get the program
                            • download latest version from github here.
                            • extract the zip file into an empty directory.
                          • Linux: Compile the program (Detailed build FAQ coming soon)
                            • change into that directory anr run ‘autogen.sh’
                            • correct any errors that may be show. Typically some build tools may be missing.
                            • run ‘make’ and optional ‘make install’ as root.
                          • Run cgminer
                            • run “cgminer --neoscrypt -o http://: -O :” *without the “quotes”

                          Is this part of guide still actuall?

                          I mean when I download this and version from 0.8.7.0 announce thread I get something totaly different.

                            That is the link to the latest 3.77b, so they should be the same.

                            the link from the announce thread is

                            https://github.com/vehre/neo-gpuminer/

                            The link you have above is just going one step further alone and linking to the zipped version

                              Would be great to have step by step guide for complete idiots like me :)

                              Something like:

                                Anyone tryied with AMD Catalyst 14.6 Beta for Linux?

                                EDIT: with the help of tutorial from high on coins I managed to isntall catalyst (14.6) and card driver (just used different paths)

                                However when running autogen.sh I see the following bugs:

                                Screenshot_from_2014_10_18_18_27_53.png

                                Any hint?

                                EDIT2:

                                sudo apt-get install libtool

                                sudo apt-get install curl

                                and

                                sudo apt-get install libcurl4-gnutls-dev

                                sudo apt-get install libudev-dev

                                fixed it

                                Hurray! I launched cgminer :)

                                Hmm not so sure what to do next.

                                There is plenty of readme files (even for scrypt or keccak) but Neoscrypt readme is more about Neoscrypt story than help with set up…

                                I am here:

                                  no linux guide and fork is soon!

                                    Is the NeoScrypt kernal .cl file in the folder you are making from?

                                        Sorry Gentlemen,

                                        but it seems that opencl libraries and ncurses are not found by the configure script.

                                        I never tried to compile cgminer with AMD drivers 14.X but I think this is not really a Neoscrypt related problem and the same problem may occur with any software you try to build on the system.

                                        My suggestions:

                                        • check that ncurses and opencl are installed.

                                        • try the —dir or --lib option. and point it to the directories where opencl/curser are

                                        ./configure --help gives hints how to use it

                                            I thought that AMD drivers 14.x had issues working with cgminer and you shouldn’t go higher than 13.12
