Intel DP45SG

Please post the exact part-number and/or link to the RAM versus a guess.

Corsair CM3X2048-1333C9DHX XMS9-1333 2048MB 1333MHz 9-9-9-24 1.5v ver 5.2 09471080

Well Corsair doesn't list your Intel DP45SG
Certified Intel DP45SG {nearly a nothing list} - http://www.intel.com/support/motherboards/desktop/dp45s...

I assume that the RAM is installed as follows or visa versa Black/Blue and properly seated. The Speed, CAS and Voltage is comparable so theoretically 'could' work, but theory and mix-match RAM is not always the case.

Blue DIMM slots:
2X2GB DDR3 Corsair CM3X2048-1333C9DHX {9-9-9-24 @ 1.6V) <- lot of compatibility issues.

Black DIMM slots:
2X2GB DDR? Corsair XMS9-1333 2048MB {9-9-9-24 @ 1.5V) <-unknown model

You need to post the following using CPUz - http://www.cpuid.com/softwares/cpu-z.html

This hardware has not been installed as yet. I don't want to have any compatability problems. These items were a gift and I don't want to return them without cause. My wife gave this to me and asks if I have used them yet. I do not wan't to hurt her feelings about this. If at all possible can compatability be established without this diagnostic test?
