IBM-compatible 16 GB DDR4-2133 registered ECC RDIMM, 2Rx4 CL15 at 1.2 V
This 16GB DDR4-2133 registered DIMM is built for servers and workstations that require error-correcting memory. The 2Rx4 dual-rank organisation and 1.2V operating voltage follow standard PC4-17000 specifications. It targets administrators upgrading or repairing IBM-compatible platforms.
The module uses registered signalling and on-die ECC to maintain data integrity under continuous operation. CAS latency is rated at CL15 at the 2133 MT/s data rate. The 288-pin form factor fits standard DDR4 RDIMM slots without adaptation.
Registered buffering reduces electrical load on the memory controller, allowing stable performance during sustained workloads. The 1.20V supply keeps power draw predictable over long periods. Major-brand DRAM components meet or exceed the referenced OEM specifications.

The module runs at DDR4-2133 with CL15 latency and 1.2 V, delivering PC4-17000 bandwidth once the memory controller trains the link.
The register adds one clock cycle of buffering, allowing the 2Rx4 organisation to present 16 GB per DIMM while keeping signal integrity at 2133 MHz.
It fits a standard 288-pin DDR4 RDIMM socket; the module height is 5.1 units so the chassis must allow that vertical clearance.
