You do know you are supposed to put dual sticks in the same colored ram slots, right? It should tell you how to install the ram chips in your manual.
Yea, manual pairs A1/B1 and A2/B2. I have heard of the manual being wrong so I tested it just in case and that wouldn't even boot up.
At least in A1/B1 and A2/B2 I can boot up into Windows for a while.
