6.4.3.2 Memory Subsystem Architecture

G530 V2 provides 24 slots for installing DDR3 DIMMs. Each CPU integrates 16 memory
channels: 1A, 1B, 1C, 1D, 1E, and 1F for CPU1, and 2A, 2B, 2C, 2D, 2E, and 2F for CPU 2.
See
Issue 02 (2017-12-15)
NOTE
l CPU 1 must be configured with DIMMs. If DIMMs are configured only for CPU 2, the
compute node cannot be powered on.
l Number of DIMMs per channel ≤ Number of ranks per channel/Number of ranks per DIMM
DIMMs of different types (RDIMMs and LRDIMMs) cannot be installed on one G530
V2. Mixed use of RDIMMs or LRDIMMs of different models is supported during
capacity expansion but may affect the DIMM RAS feature.
All DIMMs in a server operate at the same speed, which is the lower of following:
– Memory speed supported by a specific processor.
– The lowest of the maximum operating speeds for selected memory configurations.
