We would suggest 256-512MB to be the minimum for running a typical system running Windows XP and general applications. As a general rule the more memory you can have available the better your system will perform. (Although on 9x systems large amounts of memory can cause your system to slow down without adjustments being made).

Below is guidance about the different memory types avilable, to ensure compatability please check your motherboard manual or related website for advice.

DDR Memory (184-pin DIMMS). These were introduced in 2002 to replace the earlier SDRAM format. To use this type of memory you need a 184-pin socket for the module to fit into.

DDR 184 DIMM Memory

DDR Memory is available in different speeds of PC2100, PC2700, PC3200 (DDR400), and PC4000 (DDR500). The modules can be used singly or how desired however you cannot mix different speeds together.

DDR2 Memory (240-pin DIMMS). This format builds on the technology of DDR. This standard has more pins and its main developments are the ability to run faster whilst consuming less power.

DDR2 Memory

To use DDR2 memory you need a 240-pin socket for the module to slot on your motherboard. DDR2 Memory is available in many different speeds including PC2-3200 (DDR2400), PC2-4200 (DDR2533), and PC2-5300 (DDR-667).
The modules can be used singly or how desired you can install different speeds of DDR2 memory together if your motherboard supports the faster speed however faster modules will perform at the lower speed.

This may be worth considering if you want to run Dual-Channel memory where you must use the same speed and ideally matching pairs to ensure compatibility.
