      If you are using the ga-797oc-3gd cards then that setting is what i run for 755Khs so you must have a driver issue sommat?

      Have you cleaned up ALL of your drivers and reinstalled 13.1?

      See here for the fun and games i had. http://forum.feathercoin.com/index.php?topic=1342.0

        I am pretty sure I did all of that but am going to try your steps and see what happens. Maybe I messed up with a wrong version of SDK or something somewhere. Thanks again and I will report back shortly with more :) baby steps

            What catalyst version are you running? Are you also using any OC utilities ie MSI Afterburner?

            It looks like you have not followed the scrypt readme that came with CGminer…i went from 560KH/s on my own to following the readme exactly and getting 680Kh/s now (i need to get catalyst 13.1 and ill jump over 700KH/s).

            My advice is only set the Intensity, Gpu, and Mem Clock rates. Thread concurrency should get defined the first time you run CGminer for your card. Everything else is not really worth messing with.

              I hear what your saying but I have 20 of those cards all running identical settings as posted pulling 755Khs. If he can’t get the same then it aint a tuning issue, it’s a driver issue. I dont use the setx stuff either.

                Just did a full uninstall as well as deleted some files from system32 folder before reinstalling full 13.1 catalyst pkg. Tried installing 2.8 SDK but installation kept failing so now installing 2.7 and starting back from scratch with the readme.

                Thanks for everyones help!

                  Had a chance to walk my way thru the read me with a 13.1 catalyst and 2.7 sdk. This is what I came up with on the tweaking and still ended up with a 530 Kh/s. Nothing done on MSI afterburner except for auto fan selection :

                  Code: [Select]

                  [code]cgminer --scrypt --auto-fan -o http://feathercoin.is-a-geek.com:8341 -u worker.1 -p xxxx -I 13 -w 256 --thread-concurrency 22400 --gpu-engine 1125 --gpu-memclock 1650[/code]

                  any other ideas? When I installed the catalyst package was I supposed to unselect any options? i noticed a SDK was installed in the pkg?

                    Its WDC so there are so many rejects because their block time, but beleve, on any scrypt coins speed absolutely same

                      are you on 13.4 catalyst and 2.7SDK? also have you tried adding -v 1? seems like it reduced stales sometimes in testing but might of just been coincidence

                        Yes, driver 13.4, with SDK included with it.
                        Not installed all that crap which comes with drivers, just driver itself.
                        -v doesnt work with SCRYPT minig, you can see its readme:

                        –vectors XX (-v XX)
                        Vectors are NOT used by the scrypt mining kernel.
                        SUMMARY: Does nothing

                        so it not affect stales at all

                          hmmm…I just did a Full Express install of 13.1 then also installed SDK 2.7 on top of that. Should I uninstall those and then just install 13.4 full and thats it?

                            Yes, better uninstall all with AMD removal utility. ([url=http://sites.amd.com/us/game/downloads/Pages/catalyst-uninstall-utility.aspx]http://sites.amd.com/us/game/downloads/Pages/catalyst-uninstall-utility.aspx[/url])
                            Reboot, did custom install of 13.4, select only driver in components, they included SDK in all latest drivers, you didnt need install it separately.
                            Then start cgminer with settings i given above, and you’ll see 750 kh on your card :)

                                  uninstalled and installed 13.4 as suggested and ran :

                                  [code]setx GPU_MAX_ALLOC_PERCENT 100
                                  setx GPU_USE_SYNC_OBJECTS 1
                                  cgminer --no-submit-stale --scrypt -w 256 -g 1 --thread-concurrency 8192 --intensity 13 --gpu-engine 1100 --gpu-memclock 1500 --gpu-fan 100 -o http://feathercoin.is-a-geek.com:8341 -u worker.1 -p xxxx --api-listen --api-network --api-allow W:0/0[/code]

                                  Giving me 545ish :/
