I have 4x6970 rig and my problem is, that with ATI Tray Tools (ATT) I can only over/under clock first two cards when I tick the "applly to both GPUs".
What I need to achieve is to overclock the GPU as much as possible (~1000 MHz) and underclock the memory as much as possible (~300 MHZ) on all cards.
I haven't been able to find any other software that could downclock the memory to 300 MHz while overclocking GPU, so in this ATT is just perfect.
In afterburner or ATI Overdrive for example I can overclock all of the cards very nicely, but the memory clock is somewhat linked to the GPU clock (if the GPU clock is under 850 MHz it lets the mem clock to 725 MHz, if the GPU is more than 850 MHz the lowest mem clock I can set is 1375 MHz).
So my question is: Is there any way to apply this overclocking profile in ATT to ALL of my cards, not just 2 of them? Or is there any other software that can downclock the memory on my cards in the same way that ATT does?
PS: Modding BIOS in RBE and the flashing with ATIFlash is giving me a BSOD, so that is not an option.
Thanks for any help.
