New to DDR2

[Rubics]

Hello everyone,

I just got an Intel Desktop Board D945PSN and Pentium D820(800MHz frontsidebus). The board supports DDR2 667, DDR2 533, or DDR2 400 MHz chips(also supports dual channel mode). I was thinking that the 400MHZ chips would work the best with the 800MHz bus. Is this correct? or would one of the faster chips work better. On my AMD Athlonxp rig I had better performance and stability with ddr333Mhz chips than with ddr400MHz chips. I think the front side bus was 166MHz.
Any help would be greatly appreciated. :)

Thanks,
Rubics

go for the fastest that it will support. DDR2-667

Isn't your system performance and stability better if the system bus speed and the memory speed are equal or divisible evenly by each other?
I have never messed with DDR2, that is just the experience I have had with older memory types.
If I remember right, different speeds would cause wait states since the data was traveling at different speeds. :confused:

Rubics, that was only a problem with old AMD systems.

You want the fastest DDR2 speed your system can support.

Right, these Intel system really like more memory bandwidth. Get two matched sticks of DDR2-667 RAM for dual channel performance.

Thanks for the replys everyone. I really appreciate the info.
The hunt begins for some DDR2-667 then. :)
