      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
      [/quote]

      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 :/

                            it is a GV not GA? GV-R797OC-3GD

                            This is what i have :

                            Display device : AMD Radeon HD 7900 Series on Tahiti GPU
                            Display driver : 9.14.10.0969, Catalyst 13.4
                            BIOS : 015.022.000.004
                            GPU: Gigabyte HD 7970 3072MB GDDRS
                            GV-R797OC-3GD

                            I am thinking my BIOS might be too old and needs to be flashed after trying everything. I bought this GPU from craigslist a couple days ago so

                              Sorry - i meant GV. GA are my mobo’s. :-[

                              Firmware is a possibility - all mine are 007 fw.

                              Worst comes to the worst blow it all away and start again. I had to do this with a build where I added 2 cards a week or so later.
                              The additional cards were 150Khs less.

                              That card is definitely good for 750.

                                Is updating the firmware and updating the BIOS the same thing? Do you have any idea about how to go about this process? Pretty sure this is my problem as nothing else seems to work. Should I maybe try going back to 13.1 catalyst instead of 13.4?

                                  Yes, they are the same - http://bit.ly/15614BI

                                  I only use 13.1 as it seems the most stable

                                    From the following link which BIOS should I flash to : [url=http://www.techpowerup.com/vgabios/index.php?manufacturer=Gigabyte&model=HD+7970]http://www.techpowerup.com/vgabios/index.php?manufacturer=Gigabyte&model=HD+7970[/url] Should I go from my GV-R797OC-3GD to a OT?

                                      No.

                                      As i have said. I run stock (but slightly OCd) gv-797oc-3gd on the 007 bios and get 755KHs. If you cant get the same rates from the same cards then there’s an issue with your os/drivers.

                                      Maybe do a complete re-install of windows AFTER you have updated the bios to THE CORRECT bios for your card and forget all the GPU_MAX_ALLOC_PERCENT 100 etc. I dont use all that stuff and hash faster than most with those cards.

                                      Follow these general instructions…

                                      1. Vanilla install of win7 x64
                                      2. Patch windows fully
                                      3. install .NET 4.5
                                      4. Install latest AMD chipset drivers (select custom but install everything (inc video drivers)
                                      5. Install 13.1 card drivers (some report success with 13.4 - i have had grief with it)
                                      6. Install cgminer 3.1.1
                                      7. Run this in your start script and FORGET all the other switches.

                                      [code]cgminer --scrypt -o -u -p x -o -u

                                          I think i will just have to do this today then if i can find my windows 7 cd somewhere. I guess one question is installing the chip drivers the same as installing catalyst software? I have only downloaded and installed Catalalyst 13.4 but keep seeing a mention about chip software and not sure what that is? Are you also installing a seperate SDK from what is in the catalyst pkg already? Thanks for the advice! hoping to fix it this weekend

                                            Just a heads up I did a complete uninstall of 13.4 catalyst and am now on 12.8 with 2.7 SDK and still cannot get past 550 kh/s. Now you said i should update the bios before and am now at that point where I am going to do that but am not exactly sure which BIOS to update to. Can please point me to the correct BIOS for this card that you think might be better? Thanks so much for your help!
