Supported Maximum RAM Per Computer Platform

This page tells you what you can use at a maximum on your motherboard, depending on your system type (desktop or laptop) and chipset/CPU.

Generally, you should NOT try to put faster RAM than your chipset/CPU supports, or else you may encounter crashing, freezing, and who knows what else? Simply avoid it.

  1. Only supports 32-bit memory addressing; only up to 3.5GB will be usable, no matter how much you go above it.
  2. RAM generation depends on your motherboard. DDR2 boards cannot take DDR3 or vice versa.
