NOTE
l The DIMM slots of CPU 1 must be configured with DIMMs. If DIMMs are configured only in
the DIMM slots of CPU 2, the compute node cannot be powered on.
Figure 2-9 shows the
positions of CPUs 1 and 2.
l Restriction of the number of ranks supported by each channel on the maximum number of
DIMMs supported by each channel:
Number of DIMMs supported by each channel ≤ Number of ranks supported by each memory
channel/Number of ranks supported by each DIMM
3. A compute node cannot be configured with DIMMs (RDIMMs or LRDIMMs) of
different types.
4. All DIMMs operate at the same speed, which is the smaller value of:
–
Memory speed supported by a CPU
– The smallest values among the maximum operating speed of specific DIMMs. See
the
Maximum Operating Speed in Table 4-1 .

DIMM Slot Configuration Rules
The G530 V2 provides 24 DDR4 DIMM slots. Each CPU integrates six memory channels.
The memory channels for CPU 1 are 1A, 1B, 1C, 1D, 1E, and 1F, and those for CPU 2 are
2A, 2B, 2C, 2D, 2E, and 2F.
Table 4-2 lists channels for each CPU.
Slots 1A1, 1B1, 1C1, 1D1, 1E1, 1F1, 2A1, 2B1, 2C1, 2D1, 2E1, and 2F1 are the primary slots
of channels 1A, 1B, 1C, 1D, 1E, 1F, 2A, 2B, 2C, 2D, 2E, and 2F, respectively. When
installing DIMMs, install the primary DIMMs first.
