Hello yvesj and welcome to the forums

The hard drive and CPU that you use will work regardless of the RAM you have (be it DDR3 or DDR2). You just have to make sure that your CPU is the same socket as your motherboard and that your motherboard supports the type of RAM you go for. Post your specs and we can have a look over them for you

Tom

i will post the 3 parts that i will buy .

here is the mobo[ASRock A785GM-LE AM3/AM2+/AM2 AMD 785G Micro ATX AMD Motherboard

here is the cpu [AMD Athlon II X3 455 Rana 3.3GHz Socket AM3 95W Triple-Core Desktop Processor ADX455WFGMBOX

here are the memory [G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL4D-4GBPI-B

now i have 2 brand new pc that i build last fall .
now i am only using the one that am on now .
so i want to use the secound computer brand new .
put the new board in and the other 2 parts in .
now the gardrive in it is a wd 750 black a really good one .
really my cpu is good for the ddr2 board here is what it is [amd athlon 11x2 270 .
so i could use it and not buying the one i send you the link or name .
so i will have a faster computer ddr2 plus a ddr3 in the same computer .
so why build a complite new pc from the case up at least 800.00 in parts
