64 GB DDR4-3200 ECC RDIMM for Lenovo servers

This single 64 GB registered module runs at 3200 MT/s with CL22 latency and 1.20 V operation. It targets administrators upgrading compatible Lenovo server or workstation platforms that require ECC registered memory.

ECC registration and 2Rx4 organisation protect

The registered buffer and error-correcting code reduce electrical load on the memory controller and detect single-bit errors. The 2Rx4 rank layout maximises density per DIMM slot without adding heat spreaders.

Standard 288-pin DDR4 RDIMM installs in minutes

Insert the module into an approved slot following the system manual population rules. Mismatched ranks, mixed voltages or unsupported motherboards will prevent boot or cause instability.

Questions about this item

Will the 2Rx4 ECC RDIMM module require any firmware updates or periodic replacement?

ECC registered DIMMs have no moving parts or firmware; they run until a correctable error rate rises, at which point the module is simply swapped.

Does the CL22 CAS latency or the PC4-25600 bandwidth ceiling appear first during continuous server loads?

The PC4-25600 bandwidth ceiling is reached before CL22 latency becomes the bottleneck in sustained throughput workloads.

How much heat and power does a single 1.20 V 64 GB stick produce when running 24/7?

At 1.20 V the module draws only a few watts and stays cool enough that no heat spreader is fitted.
