I have an Intel D915PBL mobo.


I have three identical 512 sticks of DDR2. What is the best way to arrange these guys in the four slots to get the most out of the ram?

I don't really undertand the diagrams that Intel sent with the mobo about channels A and B etc.

For now I just have the sticks place in the first 3 consecutive slot from top to bottom and it appears to be running in single-channel mode (?). Is this normal? I don't really understand ram. Any help would be greatly appreciated.

TIA

You cannot run only 3 sticks and expect dual-chan operation. You can run 2 sticks in either the blue or the black channels. The two sticks of ram must reside in the same color slots in order for the motherboard to run dual-channel. Now it's a waste to have that extra ram stick and not use it, however, the only option is to buy another matching stick.
