Memory rules
For optimal performance, memory should be balanced between the two processor boards. If you do not
balance the memory correctly, the NAS Gateway 500 will function with reduced performance.
Memory placement rules:
v
All memory FCs contain four DIMMs of equal size (one quad).
v
Memory is plugged in one quad at a time.
v
Placement order is from the lowest to the highest MB-size quads (FC 4452, 4453, 4454)
v
Populate the quad consisting of J0A, J1A, J2A, and J3A first, then populate the second quad (J0B, J1B,
J2B, and J4B).
v
If you have two processors, populate both first quads, and then populate both second quads.
