I have tried the fix with the profile changes with CCC. (changing the idle core clock)
I have overclocked with AMD Overdrive and MSI Afterburner and Trixx. (obviously not at the same time)
I am at a loss for what to do. I realize these cards are kinda old so I thought I could find an answer on a forum, but I have been looking for 3 hours straight with no luck. I am wondering if I should consider flashing my GPU bios?
Also I have tried running the cards separately (ie 1 card installed at a time) and both cards exhibit the same behavior independently. Its like they cant be overclocked for some reason, but i know they can!
I also feel like they cards under perform in crossfire which is why i want to overclock them.
Intel i5 760 @ 3.5
8Gb G skill ram
windows 7 pro 64x
Sapphire HD 5770
XFX HD 5750
Thanks for any help!
