quick question.
I have 1 stick that will hash just happy at 924, another won't budge past 796. Can I set them to run those frequencies on the same scrypt?
Yes:
... -S MLD:all --set MLD@COM7:clock=924 --set MLD@COM8:clock=796
(official notation should be --set MLD@\\.\COMx:clock=nnn but this works as well)
