NF7-S2.0 DDR Problem...

I cannot seem to get dual channel to work with this board, or even 2 sticks of memory period. I have 2x512 Nanya DDR and I can only use one at a time. If I add any additional sticks I get the one long beep code. I've tried several different combinations of memory but no matter what I can only have one stick in and any additional stick gives me the beep code.

Any suggestions would be greatly appriciated, thanks.

Also, the memory works fine in my A7V8X.

Now, does the beep stop? Or does it just keep on going? Does your machine do a long beep then shut down? What slots were you trying them in?

Thanks for the fast reply, it doesn't shut down its just a long beep that repeats about every 5 seconds.

I have tried them in every slot, the manual says start from dimm3 and work your way down. I've tried them in 3 and 2, 3 and 1, all with the same result.
