      only 4GB.
      I bought components to build a proper rig, hopefully this w-end, with a 7970 and 290, in there I will put 8GB Ram, is that enough?
      I never heard before about deleting the .bin file.
      I’m using cgwatcher by the way, so I point it out to the .conf, but if I were to use cgminer on its own is enough to name the file cgminer.conf and open it? not .bat ?

      I only had 4GB until last week and it worked fine, I might have been using a slightly lower thread concurrency though I cant remember for sure.
      It’s fine to use cgminer on it’s own with the cgminer.conf file, I dont use a batch file at all, I just have a shortcut to cgminer.exe in my start up folder in case the rig reboots it will get back hashing automatically.

        thanks for the feedback. I’ll do some research on how to avoid Hardware errors, and as you all did spend a couple of weeks to find the best tweak. It sounds very straight forward the way with cgminer in start-up folder and cgminer.conf .
        thank you again.

          This might be a bit redundant, but I found both my 280x had problems with hardware errors until I ran:

          setx GPU_MAX_ALLOC_PERCENT 100
          setx GPU_USE_SYNC_OBJECTS 1

          So I’m posting that as a longshot.

          In my impression you should have zero hardware errors and a reject rate well below 1%, but the latter depends on lots of variables in your choice of pool and chosen card config.

            Yeah, i keep forgetting those values, if you dont set em you are bound for high HW if thread-concurrency is set high:)

              me again…such a newbie…sorry…
              if I try with conf suggested above for example I get this error:
              [img]http://imageshack.com/a/img854/524/z22h.png[/img]

              where do you insert this: in the .conf file right?
              setx GPU_MAX_ALLOC_PERCENT 100
              setx GPU_USE_SYNC_OBJECTS 1

              …ah found it… the .bat file… Iread about it somewhere but then forgot altogether…argh…

                You can put it at the start of a .bat file like this:

                setx GPU_MAX_ALLOC_PERCENT 100
                setx GPU_USE_SYNC_OBJECTS 1
                sgminer.exe -o (your mining pool) -u (your user id) -p x -g 2 -w 256,256,256,512 -I 13 --thread-concurrency 8192,8192,8192,10240 --lookup-gap 2 --gpu-engine 1055,1055,1055,1025 --gpu-memclock 1500 --gpu-powertune 20 --gpu-fan 30-100 --temp-target 70 --temp-overheat 90 --temp-cutoff 95

                Or run it once from a dos prompt…

                  if I use the .bat file that has all the info don’t need the .conf file anymore? I just run the .bat
                  ok got it.

                  does this seem ok? I kept concurrency work and memlock and engine low…
                  setx GPU_MAX_ALLOC_PERCENT 100
                  setx GPU_USE_SYNC_OBJECTS 1
                  cgminer.exe -o stratum.wemineftc.com:4444 --scrypt -u xxxx1 -p xxx -I 15 -g 1 -w 256 --thread-concurrency 8192 --gpu-memclock 1050 --gpu-engine 855 --gpu-powertune 20 --gpu-fan 30-100 --temp-target 75 --temp-overheat 90 --temp-cutoff 95

                  but with this result: see loads of errors again ?!?!?

                    That does seem a little low…

                    you might want to bump it up.

                    Most people have memclock at 1500, some at 1250…

                        Assuming you are on windows, I ran these once in start > run:

                        [table]
                        [tr]
                        [td]setx GPU_MAX_ALLOC_PERCENT 100
                        setx GPU_USE_SYNC_OBJECTS 1[/td]
                        [/tr]
                        [/table]

                        I’m a Linux guy, but used win for our miners as one is at a mates place - easier for him to learn. I think they are environment variables of some kind, so once they are set, they are set. In short I think you can leave them out of the batch file for your settings.

                        Also you should ditch any kind of tuning (by config or otherwise) until you can mine at all without errors! Start with a lower intensity and a basic config, such as:

                        cgminer.exe -o stratum.wemineftc.com:4444 --scrypt -u krasticrypto.1 -p xxx -I 15

                          R9 290 Asus.
                          Windows 7
                          That’s why I put the lowest config I could think of…just to start mining really! I wasted days already…
                          so the miner is running with that .bat file but HW is super high right?! :-\
                          Is it just a matter of tweaking? no major mistake that you can spot from the .bat?

                              yes I did run them 1 line after the other in CMD and removed them from the .bat file.
                              also removed the .bin file.

                                  latest Catalyst I believe is 13.11
                                  and also AMD-APP-SDK-v.2.9

                                    Well you shouldn’t be getting those hardware errors with those tame settings, you should just be getting a low hash rate.

                                    Have you uninstalled and reinstalled your drivers?

                                      aaaaaaaaaaah 0 errors now!
                                      with intensity 11 and concurrency 16384
                                      ok I’m getting somewhere!
                                      at least there isn’t anything totally wrong with the set-up. that’s all I want. would you mind double check it looks fine? I’ll work on getting higher KH/s slowly tweaking…

                                        You normally set your thread concurrency, then memclock, then engine…

                                        Clear all the bin files out of your CGMiner directory and run it without a thread concurrency setting, it will then give you a good starting TC in the first bin file it creates…

                                          ok I’m getting 774KH/s now with these and no error

                                          setx GPU_MAX_ALLOC_PERCENT 100
                                          setx GPU_USE_SYNC_OBJECTS 1
                                          cgminer.exe -o stratum.wemineftc.com:4444 --scrypt -u krasticrypto.1 -p xxx -I 20 -g 1 -w 256 --thread-concurrency 24576 --gpu-memclock 1250 --gpu-engine 855 --gpu-powertune 20 --gpu-fan 70 --temp-target 75 --temp-overheat 90 --temp-cutoff 95

                                          not sure what fixed it but I guess running in command those 2 lines? and fine tweaking? mmm…
                                          I’ll post the config somewhere if I obtain better results.

                                          THANK YOU SUO MUCH EVERYONE!!!

                                            Now edit the password from your post above and change it at the mining pool. lol 8)
