The QVL (qualified vendors list) is here:

ASUSTeK Computer Inc. -Support- Drivers and Download P5G41C-M LX

It doesn't list any DDR3-1333 memory, though. That doesn't mean that it's incompatible; Asus may simply have not tested it.

Is there any reason you're looking at a motherboard with two DDR2 slots and two DDR3 slots? I hope that you're aware that you can't use DDR2 and DDR3 at the same time. In effect, you'll have two memory slots. (On the other hand, if you want a microATX board like the one you've listed, most of the Socket 775 ones seem to have only two DIMM slots. www.newegg.com lists a few full ATX boards with 4 slots, but Newegg doesn't ship to South Africa.)

I have a board it only takes DDR2 and that ram is so exspensive I might as well buy a new board and faster RAM.....Memory Graphics
DDR3-1333 | DDR3-1066 | DDR2-1066 | DDR2-800 | DDR2-667 PCI Express | PCI

I also have a question if I have windws 7 ultimate 32bit does is it any good if I have 4gig, does the games use the whole 4gig or what, becuase windows only use only 1gig or so?

Windows 32 bit of any variety XP/7 or whatever will only see 2gb...if you want to run 4gb you will need a 64 bit OS for it to be seen/utilised.

If you are buying a board that runs DDR2 and DDR3 you can only use one or the other not both. Both Corsair and Mushkin have good quality Ram tho personally I think Mushkin is the pick of the 2 and normally can be well and truly overclocked.

Are you stating a fact?

It's been my experience that a 32-bit system loaded with 4GB RAM will see about 3.25GB. This behavior is due to something called memory mapped IO reservations. Those reservations overlay the physical address space and mask out those physical addresses so that they cannot be used for working memory. This is independent of the OS running on the machine.

The highest address accessible in a 32-bit system is 2 raised to the 32nd power which equals 4GB. But of those 4GB's the system will reserve a portion of the memory for the BIOS, PCI bus, PCI express, etc. And that usually amounts to roughly 512MB - 1GB (plus or minus a few hundred MB) depending on the specific system.
