this might be obvious for some but it wasnt for me till just now
i have a rig ive been testing with a 7950 a 280x a 470 4g and a 470 8g everything was working fine, eg msi 470 4g was hashing happily at 28Mh
but since last night some setting got stuck in windows somewhere or something and no matter what it wouldnt break 23Mh
did everything switched risers, removed everything and put card in pci slot, ddu drivers and reinstall, reset in watttool and radeon settings, switched every cable
only thing that work was switching to a different machine, thought i janked my cards mem controller or something, but its fine now in this new machine
hopefully windows is the problem at this point and i just need a fresh install on that machine
but if ur having issues when optimizing this might be the problem
the reason i think its watttool is because loading profiles works np when just 400s in but any other series and the profiles load intermittently and nothing seems to fix it even removing the cards
