PHS-memory 32GB RAM memory for Lenovo Flex System x880 X6 7903 (E7-8800 v2) DDR3 LRDIMM 1600MHz PC3L-12800L

This 32GB RAM is 100% compatible with the Lenovo Flex System x880 X6 7903 (E7-8800 v2). What memory configuration is possible? Our memory team is happy to assist you in choosing the right RAM and configuring your server.

Maximum RAM configuration:

• RDIMM: 384GB RAM (24 x 16GB RIMM), 768GB (48 x 16GB RDIMM)
• LRDIMM: 1.5TB RAM (24 x 64GB LRDIMM), 3TB (48 x 64GB LRDIMM)

Registered DIMM and Load Reduced LRDIMM memory modules must not be mixed. Therefore, when upgrading, you should know what memory is already present or upgrade completely with LRDIMM memory.

Principles of memory configuration:
A CPU is equipped with 2 memory controllers. Each memory controller has 2 SMIs (Scalable Memory Interfaces) with up to 6 memory slots. Thus, a CPU can address up to 24 RAM modules (2 controllers x 2 SMIs x 6 DIMM slots).

Memory slots without a processor present must not be populated.

Memory configuration for good system performance:
Optimal performance is achieved with 4 or 8 identical memory modules per CPU. When populated with 8 DIMMs (1 DIMM per channel), 16 DIMMs (2 DPC), or 24 DIMMs (3 DPC) per CPU, interleaving is optimally supported across the memory controllers and memory channels. This allows for maximum performance in Independent Mode and Lockstep Mode. Configurations with 2 DIMMs, 6 DIMMs, or 10 DIMMs per CPU are not recommended.

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