i have :
msi p45 8d memory lover which support ddr2 and ddr3
intel cor to quad Q9550 2.83 (133)
i have 2x2GB ddr2 800 and i want to put ddr3 1333 to match FSB of CPU but i saw this :
http://ixbtlabs.com/articles3/cpu/ddr2-800-vs-ddr3-1333...
that is the problem no real performance
so what should i do "is to stay on ddr2 800 or does it worth to change to ddr3 1333
or if i change to ddr3 1600 does also make sense !!!

More about : ddr2 ddr3

Not sure what mobo you have as MSI sells the Platinum and Neo-F in the USA. I haven't heard of one board that can support both DDR2 and DDR3 at the same time. Don't worry about the RAM too much the ones you already as DDR2 can't go above 1066Mhz speeds anyway. (DDR3 1600 isn't really worth it as Intel's newer CPUs only natively run the memory at 1333 anyway)The baords don't support DDR3 only DDR2.

mister g, http://www.msi.com/index.php?func=proddesc&maincat_no=1...

The board supports DDR2 & DDR3 (maybe hence called "Memory Lover").

About the answer, well,.. maybe the system will run at slowest speed of installed Ram. The difference between 800 & 1333 is also very small. As seen in the article ~2%? So I'd say, if you have DDR2, then stay, no need to get DDR3. If you don't have any ram and want to purchase new, go for the cheapest one. If both are of same cheapness, go for DDR3.

Maybe you should contact the MSI to ask if mixing DDR2 and DDR3 asking what memory will be compatible for the mix in this board.
