Server DDR4 ECC RDIMM
This 16GB registered DDR4 module targets server and workstation administrators who need error-correcting memory for stable operation under continuous load. The single DIMM plugs into a 288-pin slot and runs at the standard 1.2V DDR4 voltage.
Registered 2Rx4 build with major-brand chips
Registered signalling and a dual-rank 2Rx4 organisation reduce electrical load on the memory controller, allowing larger total capacities in multi-socket platforms. Major-brand DRAM components and full production testing support dependable day-to-day operation in mission-critical systems.
DDR4 2133 CL15 speed grade
The module operates at 2133 MT/s with a CAS latency of 15, matching the PC4-17000 specification required by the referenced Kingston part numbers. Systems that demand a different data rate or latency profile will not run this DIMM at its rated settings.

Questions about this item
Does the DDR4 2133 interface limit real-world throughput to the PC4-17000 rating?
Yes, the module runs at 2133 MHz with a PC4-17000 bandwidth ceiling, so sustained transfer rates cannot exceed that specification.
Will this 288-pin registered DIMM fit a standard server DIMM slot?
The module uses the 288-pin DDR4 DIMM form factor with registered signalling, matching the physical and electrical layout of standard server memory slots.
Do I need to populate specific slots or enable ECC in BIOS for this 2Rx4 registered module to work?
Install the DIMM in the slot sequence recommended by your system manual and ensure ECC is enabled in BIOS; registered modules will not post in unbuffered consumer boards.
