Memory Load Order - HP Integrity rx6600 User's & Service Manual

Table 73 Memory Configuration Requirements
Memory Carrier Type
24-DIMM memory carrier
(configuration 1)
48-DIMM memory carrier
(configuration 2)

Memory Load Order

When installing memory, use a minimum of one quad of like-sized DIMMs. Insert additional DIMMs
into the 48-DIMM memory carrier in the next available quad, in order of capacity from largest to
smallest.
Install DIMMs into the appropriate slots on the 48-DIMM memory carrier boards; each slot has a
unique ID. Use
CAUTION:
Do not mix DIMM sizes or types within a quad.
Load DIMM quads in order of size from largest to smallest. For example, if you have a quad
of 2 GB DIMMs and a quad of 1 GB DIMMs, install the quad of 2 GB DIMMs first.
24-DIMM Memory Carrier Load Order
For a single 24-DIMM memory board configuration, load DIMMs in order from quad 0 to quad
5.
48-DIMM Memory Carrier Load Order
The 48-DIMM memory carrier has two sides, labeled side 0 and side 1, each of which can contain
a memory carrier board. The 48-DIMM memory carrier can contain up to 12 quads of memory.
DIMM quads are loaded in order of capacity from largest to smallest.
The DIMM slot IDs are the same for both 24-DIMM memory carrier boards. Unique slots are
identified within the carrier by the side in which they reside. For example, slot 0A is identified as
slot 0A, side 0; or slot 0A, side 1.
Figure 70 shows the DIMM slot IDs for the 48-DIMM memory carrier board.
