      i have 8gb ram

      yes crossfire running, because i use it for gaming

      That card that is use in first slow will always be slower, so if i put card 2 in slot one, card 2 will be the slower one, slot 1 is the card i have my monitor plug in to :)

        my guess it would be something to do with the crossfire. to check just disable it and run your mine temporarily to see if you have any changes?

            I can tell you that my primary card gets lower KHs than my secondary but only by about 5…not 100. You seem like you know enough about computers, so my first recommendation would be to stop using GUIminer and run cgminer instead. This will give you much more control over the speeds of your cards and depending on the version you may not see this problem happen. The older 3.1 version seems to work great for almost anyone I would give that a shot.

            and read that and use the template. It may help diagnose the problem faster.

                  -d X
                  replace x with the card number, [b]sometimes they are reported in a different order than expected[/b]. If that happens cgminer will still display which cards are inactive and active. Use that to figure out which is the one you don’t want.

                            thats if you have a config file to go along with it. In that case you point to the config file with the .bat

                            then you alter the config file. Im guessing you tried to copy some settings from the other thread i made? in that case thats a config file setup without my pool info at the top

                            example

                            [code]setx GPU_MAX_ALLOC_PERCENT 100

                            cgminer --config C:\cgminerConfig.conf[/code]

                                oh yea. make sure you are not getting any hardware errors either. hashrates lie if your HW is more than 0

                                    hardware errors. if you have a number > 0 add --thread-concurrency 8192 and see what happens

                                      following up with yesterday, GCminer is doing the same as gui :( main card is still slower at around 600 and the other card is running at 670

                                      don’t know why i try switch and it’s still the same :(
