Will faster DDR2 memory work in a board rated to 533mhz

[ChuckvB]

I'e got a line on very cheap DDR2-677 memory but the ECS board is only rated to DDR2-533 memory. In the DDR days you could use faster memory and it would just be limited to the MB capibility. Does anyone have experience with doing this in the ECS P4M800PRO-M2 (V2.0) board?

Typically a motherboard will not run faster memory then it supports at stock settings. You can try Overclocking your system and run at 667. I don't have high hopes for you though, that ECS mobo is not a great overclocker.

As far as I know (and from experience) ... it should work just fine. Although you will end up underclocking that RAM to DDR2-533 spec.
However on the flip side, if you can try fiddle on the memory setting, you might be able to reduce your timing since you're underclocking that stick ... so a bit of win some lose some scenario.
