      This settings
      cgminer --no-submit-stale --scrypt -w 64 -g 2 --thread-concurrency 8192 --intensity 13 --gpu-engine 1100 --gpu-memclock 1500 --gpu-fan 100 -o http://your.pool.here:0 -u guest.4 -p x --api-listen --api-network --api-allow W:0/0
      Gives extactly 752 mh from each card.
      You can see on screenshot. Also for how many time its runnin.
      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 :)

                    [code]setx GPU_MAX_ALLOC_PERCENT 100
                    setx GPU_USE_SYNC_OBJECTS 1

                                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
