This is a RD-Ram 45ns 400MHz ECC Ram computer so the ram is faster then standard DDR Ram so no improvement sinch it is the same speed as DDR 400. I would upgrade to 4 * 512 45ns RD-Ram 400MHz ECC Ram sticks if MadHacker would pay for them.
As it is one to one with the cpu. The memory score went from a 4.2 to a 3.3 why I don't know. All I changed was the CPU not the ram. Nothing else changed.
