I have 2gb ram of DDR2 with 399mhz, and i want to purchase more ram. but before i do any mistake i want to ask few stuff

first, i found only 2gb ram of DDR2 and its 800Mhz, so i'm asking. do i can have one 800mhz card and one 399mhz card? (they both DDR2)

Second, my motherboard is:        ASUSTeK Computer INC. P5KPL-AM (Socket 775)

and i saw that my max ram is 4gb that my motherboard can support, does it 4gb for 1 card or for both? *i have 2 spaces, so i can have 2 cards*

and do i can run DDR3 with such motherboard? (like dismount the DDR2 card and use the DDR3 card)

 

Thanks if you can help.

Your motherboard can take a maximum of 4gb (2x2gb) and supports DDR2, not DDR3.  It's not a great idea to use memory with different clock speeds. In the best case scenario both will operate at the speed of the slower stick, but it could also cause errors.

Yes you can use one 800mhz, is better when you match the speed so you can benefit of the Dual Chanel speed but you can mix and match as long they are both DDR2.

It looks like your motherboard only support up to 4GB RAM, each Ram stick hast to be for 2GB RAM, take note that if your system is 32 will only see 3GB of RAM.

You can't run DDR3 is not supported for this Motherboard.
