A-Tech 16GB DDR4 3200 ECC RDIMM

This registered ECC module targets servers and workstations that require error correction and signal buffering for stable operation. It replaces specific IBM-Lenovo part numbers including 4X71B67860, 4X77A08632, 4X77A85855, 02JG337, and 4ZC7A15121. Systems without registered DIMM support cannot use this memory.

Capacity and headroom

The single 16GB stick runs at 3200MHz with a CL22 latency and 1.2V voltage. The 2Rx8 organisation provides density for multi-module configurations where the platform allows. Workloads exceeding 16GB per channel will need additional modules or higher-capacity DIMMs.

Build quality and connectors

Major-brand chips undergo quality-assurance testing before shipment. The 288-pin DDR4 DIMM form factor fits standard registered DIMM slots in compatible server and workstation boards. Registered signalling reduces electrical load on the memory controller when multiple modules are populated.

Questions about this item

Will this DDR4 3200 CL22 ECC RDIMM run alongside my existing DDR4 modules?

The module operates at DDR4 3200 (PC4-25600) with CL22 latency and 1.20V; the system will run all installed memory at the speed of the slowest module.

How can I verify the 16GB 2Rx8 registered ECC module is working after installation?

Check the BIOS or UEFI memory information for 16GB capacity, 3200 MT/s speed, ECC enabled, and registered DIMM detected.

What is included with the 288-pin DDR4 RDIMM and what must be purchased separately?

The box contains one 16GB 2Rx8 DDR4 3200 ECC RDIMM; no cables, brackets, or additional memory modules are included.
