I had the same issues with a Asus M4a785 board. DDR2 2x2gb Patriot memory. WOuldn't work in dual channel, but work in single on to different coloured dimms. Could never figured that out but I did search the difference between dual channel and single channel performance and it was minor. IMO it's nothing to worry about. Put the sticks in and boot it up.

Are the ram a set? If not, and they are individual modules, they most likely have very different timings, and/or operating voltages

So since 1 stick will work in any slot, it's not your motherboard, it's your ram.

Weather you plan to use dual channel, or single channel, the ram must still at least be close, or preferably a set!

Thats the problem right there! Look at the timings on the sticker, and see if they match, also the voltage.

Start up with one stick and then loosen the timings, and when you check the voltage of each stick, you'll need to set the DIMM voltage to the higher one.

Yah, I'd say 2.4v is plenty!

Good luck!
