      What is that power consumption for? I mean is it momentum or per hash or per second?

        I guess these watts are reported by a wall meter. Volt-amperes actually with some basic averaging.

          yep from the wall, so readings are not so “accurate” but it gives some info where we stand now

          (idle power - average power used when hashing)/gpus

          just for fun:

          so 280x gives average 50khs, uses 105w

          = 0,0021W/hash

          =476 hash/W

          This could mean that the miner isnt fully stressing the gpu.

          Andre, have you used the nvidia Insight software? I think it graphs the memory and gpu usage of the cuda cores for the particular implementation.

              No, I haven’t used that nvidia software yet. Most pressing was to get the kernel running at all and to fix the endianess issues in the protocols.

              The kernel does not know anything about driver versions and currently there is nothing that could depend on that yet. So I guess there is some compiler issue.

              The good news is, my radeon arrived today. So I can figure what is special about these cards. Unfortunately I do not run windows, or should I say fortunately :-)

                yyep…
                when i tried to create bin file with tmuir12

                4.xx drivers:
                i got double hashrate(100khs/gpu) but only HW errors.
                all other setting where just as using 13.xx drivers.
                14.xx created bin used at 13.xx drivers gave same results:double hash rate but only HW errors.

                could there be a change to get valid hashes at this double hashrate with 14.xx bin file tweaks or something?
                i could take a look how much power usage is when using 14.xx bins… if its 210W… we maybe have something

                I can’t get it working at all with 14.4 on ubuntu 14.04.

                @tmuir12. Thanks for the catalyst info. I was unaware that cgminer has issues with catalyst 14.x. I will downgrade my rig to 13.12 and see what I get.

                Cheers

                Dave

                  I’ve not tried cgminer on Linux yet. I have a VM machine with Ubuntu 14.04 on it and plan to try it this week.

                      win7, amd driver 13.something, radeon hd 7990, not good. What can I do?

                        Get an error message, when trying to start the windows version on a win7/64 PC: libgcc_s_dw2-1.dll is missing.

                        is it possible to link all libraries statically into the windows version?

                          As far as I know, are there some libraries that are not available for static linking. Anyway, why would one want to do the bother? Install the lib and be done.

                          Anyway here is the second google answer to the question:

                            thats better :)

                            7990 default settings. Strangely, -I 13 = 35 mhs, -I 12 = 46 mhs. If the gpu temp is correct then it seems that they are not loaded at all cause thats almost idle temps

                                What do i need to add the nvidia components to the build ?

                                https://developer.nvidia.com/gpu-deployment-kit

                                Google does the trick!

                                Linux: Install it to default location, or like on

                                Windows: add --with-nvml-dir= to the autogen.sh call.

                                is the path containing the include and lib directory of nvml. Make sure the .so or .dll, respectively, is on the LD_LIBRARY_PATH (Linux) or PATH (Windows) or cgminer.exe’s directory (Windows).

                                  i’ve installed the deployment kit but i do not use visual studio or have any nvidia hardware installed. Alot of the kit is not being installed.

                                  I’m building in win8.1 in mingw with amd sdk 2.9 and adl sdk 6. I have found a nvml.dl_ in anothers computer divers dir. Is that the one i need ?

                                    I am on Linux, so I can’t verify what I say:

                                    Most of all you need the includes of the NVML. The configuration process does not check for the nvml.dll anyway, because that is only tried at runtime and the initialisation is simply skipped if the .dll is not found. Furthermore, there is no need to distribute the .dll along with cgminer, because nvml.dll comes with all CUDA toolkits.

                                    That said: When autogen.sh aka configure reports it has found NVML support, then everything is fine for compilation.

                                      Was anyone ever able to get 3.7.5 to work as a solo miner?

                                      I was unable to find a way to make it locate the wallet while trying to solo mine.

                                        Ok found it, in windows you only need to install nvidia gpu deployment kit

                                        Install path is C:\Program Files\NVIDIA Corporation\GDK\nvml\

                                        How do i link this to MinGW ?

                                        Thank you

                                          So folks, assuming the gpu miner is operational, is this going livenet?

                                            PXC is live with NeoScrypt now. But Feathercoin is reasonably close to announcing a fork date / block in the not too distant future. :)
