Yea, I tried all 4 combinations with the sticks to begin with. I already knew the LA were going to be better sticks so I kept them in 1 and 2 and the LE in 3 and 4.
Its rock solid at 285mhz in windows, no errors and PI 32m clean. But even though I can pass memtest at 290mhz I can't get it to stop erroring in windows no matter what I try.
I wish both sets were LA, even both being LE would be better IMO.
