Hi, I want to order an Asus - P5G41T-M LX Motherboard and some RAM. The manufacturers specs are
listed below.

My question is basically, If I also buy 2x 4GB DDR3 1333 memory modules for this board will they work
OK? It says it supports DDR3 1333(O.C.). Does that mean it supports DDR3 1333? Or does it mean it
supports DDR3 1066 O.C'D to 1333. Please help me understand, so I don't purchase the wrong product.

Thanks.

It will support 1066 memory OC'd to 1333.

You can buy 1333 modules and put them in there, but the MB by default will downclock them to 1066, which normally would not be a problem, except it will 'relax' your timings, which can be a noticeable detriment to your system.

Well, 1333 modules are cheaper, so that's why I would rather buy them. Could you use 1333 modules and O.C them from the default 1066 back to 1333? If yes, how would you go about doing this?

Also, would there be a noticeable difference between a G31 Motherboard Running DDR2 800 and the G41 Running DDR3 1333 @ 1066?

Thanks.

I don't have that board anymore (it's been almost 4 years). It supported DDR3 1333 just fine, but ran it at 1066 by default. In order to achieve higher speeds, OC'ing was required. I assume that the same would be required to fully support DDR3 1600.
