System-specific ECC RDIMM kit

This 32 GB kit contains four 8 GB DDR3L 1600 registered DIMMs built for Lenovo Flex System Compute Nodes. It targets administrators who need to expand memory in supported blade servers without mixing buffered and unbuffered modules.

Compatibility check before ordering

Verify that the target node is an x220, x222, x240 or x440 and that the motherboard accepts 240-pin DDR3L ECC registered memory at 1.35 V. The modules will not work in standard desktop boards or in systems that require unbuffered DIMMs.

Build integration notes

Each stick is a single-rank 1Rx4 module with CL11 latency and no heat spreader, so it fits dense blade chassis without extra clearance. The kit replaces Lenovo part numbers 00D5035, 00D5036, 46W0700 and 46W0771, freeing budget otherwise spent on OEM trays.
