Memory which is slower than the motherboard memory standard?

Can the motherboard support memory which is slower than the motherboard memory standard? How much slower?

Hello,

I have 2 1GB sticks of DDR2 667 Mhz memory and a cpu with a 1066 Mhz FSB.

I need to buy a motherboard. I see motherboards which support a 1333Mhz/1066Mhz FSB and have memory standards of DDR2 800 Mhz or DDR2 1066 Mhz.

Will my slower memory work on such boards?

In some posts in various forums, I've read that it may necessary to manually set the memory speed even slower to stabilize the system. What is the slowest speeds these boards could support? Could they support 533 Mhz?

Thanks,
Jane

It'll work fine. Don't worry about it.
