I know, i know, memory clock isn't that important, but I just want to know the optimal clock. I tried searching good for graphics memory clock, but every result goes some thing along the lines of "Graphics clock doesn't matter" there's no real clocks! My card goes from 1200mhz all the way to 1445mhz, I currently have it on 1300mhz, but should I decrease? or increase and round out, like to 1333mhz? Also I only have 1gb of GDDR5.
