4x2gbs of ddr3 1600 gskill ripjaws
Here is the issue I installed new watercooling parts today redid all the blocks blah blah blah, before i did this the mobo had 4x2gbs of ddr3 and it ran fine at 1600mhz,
After installing the waterblocks and so on, the computer failed to boot into windows, so i took out all the ram but one it booted, shut down installed them all no go, put in 2 sticks good to go, 4 sticks will not boot why not?
Newer boards are particularly fussy about how tight a heat sink is. Is it possible you tightened the block a little too much? I had a similar issue with my P6T is why I'm saying this. It only recognized 4gb of ram and wouldn't boot in triple channel no matter what I did. After a ton of angry reading I found a lot of people having memory issues and the tightening thing was one of the fixes.
