Mobo & RAM: two sticks individually - good, two sticks together - bad

[Tommygunn]

I am trying to get my two sticks (2x 2Gb) of Corsair RAM (CM2X2048-6400C5C) to work in my Asus P5Q Deluxe mobo.
Both sticks work perfectly because I have tested them in all slots individually and the computer works flawlessly.
However, the problem that I'm having is when I put both sticks in, be that in A1/B1 or A2/B2.

With both sticks in, the computers powers on, the fans spin up but the computer progresses no further and does not POST - a blank screen.

What could be wrong? Is there a setting to adjust?

Tom.

The sticks should be in A1/A2 or B1/B2. Try that configuration.

See page 2-11 of your motherboard manual. If you don't have one, go here: http://www.asus.com/Motherboards/Intel_Socket_775/P5Q_Deluxe/#download

If I plug in the RAM as you suggest I will have the one in the yellow slot and the other in the black slot.

That is correct. Did you read the manual yet? That is how it's supposed to be.
