Compatibility question

[Dagon]

Sorry if this is a stupid question, but does memory that is faster than a motherboard's specs work okay, but at the lower (motherboard) speed?

What I'm trying to say is, would this memory and mobo work together:
OCZ 2GB (2 x 1GB) PC2-6400 http://www.overclockers.co.uk/showproduct.php?prodid=MY-072-OC
Asrock Conroe945G-DVI http://www.overclockers.co.uk/showproduct.php?prodid=MB-004-AK&groupid=701&catid=5&subcat=326

The mobo takes PC2-5300/5400 RAM - would the PC2-6400 work but at 5300/5400 speeds? Or would I be safer with something like this:
Corsair 2GB DDR2 XMS2-5400C4 http://www.overclockers.co.uk/showproduct.php?prodid=MY-095-CS&groupid=701&catid=8&subcat=144

Cheers

usually you can run faster RAM slower but not necessarily slower RAM faster ...

The OCZ will work fine at pc5300 speeds. You should be able to tighten its timings at that speed too.
