Server-grade DDR5 ECC RDIMM

This 128GB DDR5 module runs at 5600MHz with CL46 latency and 1.1V operation. It uses a 4Rx4 registered ECC design built for Lenovo ThinkAgile HX and VX series servers. The 288-pin form factor fits enterprise memory slots in compatible systems.

Verify registered ECC support

Confirm your ThinkAgile model appears in the supported list: HX630 V3, HX650 V3, MX630 V3, MX650 V3 or VX630 V3. This registered ECC RDIMM will not work in desktop boards or in systems that require unbuffered or load-reduced memory. Mixing memory types prevents boot.

JEDEC compliant single module

The bare 288-pin PCB has no heat spreader, so airflow across the DIMM is essential in dense server chassis. JEDEC and RoHS compliance ensures the module meets industry electrical and environmental standards. A single 128GB stick leaves remaining slots free for future capacity expansion.
