I have 2x4Gb (1600) and 2x2Gb (1600), my CPU only accepts 1333.
My MOBO:
Black (A2)
Blue (A1)
Black (B2)
Blue (B1)

Setup 1:
Black (A2) 2Gb
Blue (A1) 2Gb
Black (B2) 4Gb
Blue (B1) 4Gb
Results (CPU-Z) : Size - 12288 Mbytes Channels # - Single

Setup 2:
Black (A2) 2Gb
Blue (A1) 4Gb
Black (B2) 2Gb
Blue (B1) 4Gb
Results (CPU-Z) : Size - 12288 Mbytes Channels # - Single

Questions:
Is there any chance that I can set up dual channel with the above 2 pairs of RAM?
How?
If can't, why not?
 
Solution
First off, if the max is 1333 and you use 1600 the board/cpu will run it as 1333. No probs there.
2nd off, what do you need 12 gig for? Try and get it going 8 gig (4x2) dual chanel that will be enough for anything. If the sticks are different in respect of row 1 and row 2, (one set has chips on one side only and the other set has chips on both sides of the memory) the system will probably only function in single channel mode with all four sticks.
If you absolutely need the volume for video editing or something, single channel mode will cost you about 8%. If you dont, dual channel with 8 gig is faster for gaming.
