Faster memory than motherboard supports?

[grier]

Hi, I bought the Asrock 775 dual vsta with the intention of the 'slow' upgrade path to a conroe. The board supports DDR and DDR2. The plan is to switch to another motherboard for pci express x16 with the r600 but wouldnt mind the memory now. Problem is, the board supports 667mhz DDR2 and the memory I was going to get (here (http://www.amazon.co.uk/o/ASIN/B000BC8V9O/ref=s9_asin_title_1/202-4381851-3911820) is rated at 800.

I'd obviously expect it to run at 667 if it works, but will it?

cheers for any help!

It will work fine; memory of the same electrical specification is backwards compatible.

Meaning DDR rated at 1066 will work at 533, 667, 800, 491, 755, 391, etc...

Are there any motherboard that is standard to DDR2 1000 or 1066?
I'm about to purchase 2 gb of memory but I'm not sure whether I should go with ddr2 800 or ddr2 1000 to go on a am2 590 sli.
I take it the 1000 is faster but will my motherboard take advantage of it...?

it's for overclocking, but even then you can tweak the ratios so you won't need those kind of RAM.
to me it seems some people have cash and are anal about something like 3%, but why not if they enjoy it .
