I bought a Compaq PC and on their website it says my motherboard (A8M2N-LA) supports four DDR2 RAM slots and can use PC2-4200 and PC2-5300. The processor is an AMD AM2 3500+ and i intend tp upgrade. On another site it says a single core processor's recommended RAM is 4200 and 5300. Does this mean my m/board can support any DDR2 240 pin RAM?
