Question on Mobo/Memory combination

E

euroman812

I am building my own PC (first time) and am considering the ASUS P5NSLI
mobo. The specificiations for it say "DDR2 Standard: DDR2 667". Now, I
already have purchased DDR2 memory, but it's DDR2 800 (Corsair XMS2).
Would that be a problem? Or am I simply not going to utilize the full
potential speed of the memory with this mobo?

Any comments would be appreciated.

Normally you can user memory that is faster than required.

But I'd reconsider you choices and lean strongly towards a system based
on the new Intel Core 2 Duo CPU and an Intel chipset that supports this.

CPU support for the P5NSLI can be found on the CPU support
page. This is the list for the P5NSLI.

These are all the motherboards that support Core2 Duo. You
have to be particularly careful with some of the P5LD2 based
boards, as only particular revisions (the latest boards)
support Core2 Duo, and not earlier revisions. Shopping
by revision is all but impossible - I had to open a box
at my local computer store, to be sure I was getting the
revision I wanted, and this is not an easy service to
get from an e-tailer.

Normally I would advise visiting the Asus hosted forums, to
see if anyone has early feedback on RAM compatibility. There
is almost nothing posted here:

The problem with the latest DDR2 motherboards, is sometimes
you install DDR2-800 memory and the board doesn't start. It
may be possible to use a single stick of a slower RAM, long
enough to enter the BIOS and try some experiments. Then
install a stick of DDR2-800 with the slower RAM and see if
it will start. Or, try a single stick of the DDR2-800, instead
of trying dual channel, and see if it starts. It would seem
in many cases, that the BIOS needs a lot more work in the
memory area, so don't be surprised if the motherboard gives
you a hard time.
