PHS-memory 4GB RAM Memory for Supermicro X9DRG-O-PCIE DDR3 UDIMM ECC 1333MHz

This 4GB RAM is 100% compatible with the Supermicro X9DRG-O-PCIE. What memory configuration is possible? Our memory team is happy to assist you in choosing the right RAM and configuring your server.

RAM technology at maximum capacity:

• Maximum possible memory configuration (with 2 CPUs, each having 12 slots):
• UDIMM ECC: 128GB RAM (2 x 8 x 8GB ECC UDIMM)
• RDIMM 2Rank: 384GB RAM (2 x 12 x 16GB RDIMM)
• RDIMM 4Rank: 512GB RAM (2 x 8 x 32GB RDIMM)
• LRDIMM: 1.5TB RAM (2 x 12 x 64GB LRDIMM)

ECC DIMM, Registered DIMM, and Load Reduced LRDIMM memory modules must not be mixed. Therefore, when upgrading, you should know which memory is already installed or upgrade completely to RDIMM memory.

Principles of memory configuration:

• There are 4 memory channels per CPU, each with 2 memory slots.
• When using ECC UDIMM or 4Rank (4Rx..) RDIMM memory, only 2 out of 3 memory slots per channel can be populated.
• Memory slots without a processor present must not be populated.

Memory configuration for good system performance:

• Distribute the memory evenly across the memory slots and evenly across the CPUs.
• If more than one CPU is present, the memory should be identical (mirrored to the other CPU) for each CPU.
