Computer Memory Solutions CM2048722133ECCREG 64GB (4x16GB) DDR4 2133MHz ECC Registered DIMM - B102

Targeted server upgrade

This 64GB kit contains four 16GB DDR4 registered DIMMs built for HP ProLiant BL460c Gen9, DL160 Gen9 and DL180 Gen9 systems. It delivers ECC error correction and registered signalling at 2133MHz for stable operation in multi-socket platforms. The modules run at 1.2V with CL15 timing and a 2Rx4 organisation. Buyers needing non-ECC or unbuffered memory for workstations should look elsewhere.

Four-module kit

The package supplies four matched sticks so the server can populate identical channels across one or two CPUs. Registered buffering reduces electrical load on the memory controller, allowing larger configurations than unbuffered alternatives. ECC protection corrects single-bit errors and detects multi-bit faults without extra software. No heat spreaders are included, relying on chassis airflow instead.

Capacity and headroom

Each CPU supports up to 512GB of registered ECC RDIMMs across eight sockets, so this 64GB kit leaves ample room for future expansion. The 2133MHz speed matches the platform's native memory bus, avoiding down-clocking penalties. Systems that require load-reduced DIMMs beyond 512GB per CPU cannot use these modules.
