The RAM i bought was dual-channel(2x2GB), and came together in the same packaging. However, my computer is only recognizing one stick of RAM at any given time. I have 4 slots for RAM (A1,B1,A2,B2), and it runs correctly when I put RAM in A1 or B1. The monitor gets no signal when I use A2 or B2 at all, and when using both A1 and B1, it only recognizes one of the slots. I'm wondering if it's something I am doing that is wrong, or if what I got just isn't compatable with what I have.
I'm not positive if I need to give more information, but if I do let me know and I'll do my best.
You might try with one stick first and manually setting the speed/timings in bios, in case it is being misdetected.You'll notice on Kingston page and in bios manual that the motherboard only supports 2gb in one slot using ddr2-1066
