AS1021M-UR+ User's Manual
(however, the CPU2 DIMM slots are not required to be populated when two CPUs
are installed).
Populating two adjacent slots at a time with memory modules of the same size and
type will result in interleaved (128-bit) memory, which is faster than non-interleaved
(64-bit) memory.
Optimizing memory performance
If two processors are installed, it is better to stagger pairs of DIMMs across both
sets of CPU DIMM slots, e.g. fi rst populate CPU1 slots 1A and 1B, then CPU2 slots
1A, and 1B, then the next two CPU1 slots, etc. This balances the load over both
CPUs to optimize performance.
Maximum memory
: 64 GB of DDR2-667/533/400 reg. ECC SDRAM - if only one
CPU is installed, maximum supported memory is halved (32 GB).
Notes:
X indicates a pair of populated DIMM slots. If adding at least four DIMMs (with
two CPUs installed), the confi gurations with DIMMs spread over both CPUs will result
in optimized performance. Note that the fi rst two DIMMs must be installed in the CPU1
memory slots.
