Install a Memory Riser Card
1. For a system with the minimum configuration (two DIMMs per riser), add two more
DIMMs to memory riser slots D6 and D9 for each memory riser in the system. The end
result being that DIMM slots D0, D3, D6 and D9 (black/black slots) are all populated.
This provides one DIMM per channel configuration across memory buffers.
Additional memory upgrades are done in increments of
four DIMMs per riser, as
follows:
2. Next, populate riser slots D1, D4, D7 and D10 (black/white slots). This provides two
DIMMs per channel.
3. And finally, populate riser slots D2, D5, D8 and D11 (white/white slots). This provides
three DIMMs per channel.
The memory slots and ejector levers are color coded using a black and white color scheme.
Slots can have a black slot with black levers (black/black slots), black slot with white levers
(black/white slots), or white slot with white levers (white/white slots) as shown in the
following illustration:
