128GB DDR5 4800 ECC RDIMM Server Module

This 128GB DDR5 4800 ECC registered DIMM is built for ThinkMate HDX-QN8-52E4 high-density servers. It runs at 1.1V with CL40 latency and a 4Rx4 organisation. The module uses major OEM chips and is stress-tested for mission-critical workloads.

Server administrators needing maximum density per

This single 128GB stick suits IT teams who must populate every DIMM slot with the highest capacity available. Buyers who need non-ECC memory, unbuffered modules, or lower-density kits for consumer platforms should look elsewhere.

288-pin DDR5 RDIMM form factor

The 288-pin DDR5 RDIMM interface with on-board ECC and registered signalling is the sole specification that determines whether this module fits the target server. Verify the motherboard accepts 4Rx4 registered DDR5 at 4800 MT/s before ordering.
