2) Try running memtest86+ to verify that each individual stick is good. You need the latest memtest beta to be able to run on a sandy bridge system; the old versions will fail.
3) You need to install the sticks in either the blue pair or black pair of slots.
4) Ram is sold in kits for a reason. There is no guarantee that the same part number is constructed of the same technology and will work together. This is a rare but possible situation. Corsair should be able to tell.
