8GB DDR4-2133 ECC Registered DIMM

This 8GB DDR4-2133 module is built for servers and workstations that require error-correcting registered memory. It operates at the standard 1.2V voltage and uses a 1Rx4 organisation with CL15 latency. The 288-pin form factor fits DDR4 DIMM slots in compatible enterprise platforms.

Registered ECC with 1Rx4 organisation

The single specification that decides fit is the registered ECC design combined with a 1Rx4 rank structure. Systems that expect unbuffered non-ECC UDIMMs or a different rank configuration will not accept this module. Verify the platform memory specification before ordering.

Straightforward DIMM installation

Installation follows the usual DIMM procedure: align the notch, press firmly until the retention clips engage, and confirm the module seats evenly. The most common issue is mixing registered and unbuffered modules in the same channel, which prevents the system from posting.

Questions about this item

What does the 2133 MHz rating mean when the module is installed in a server?

The module runs at 2133 MHz, delivering a peak transfer rate of 17000 MB/s per channel when the platform supports DDR4-2133.

How does the registered DIMM interface affect usable speed and capacity?

The registered buffer adds one clock cycle of latency but lets the memory controller drive more modules per channel without signal degradation.

What physical slot and keying does this 288-pin DDR4 RDIMM require?

It fits a standard DDR4 288-pin DIMM socket with the DDR4 key notch; the registered design does not change the mechanical outline.
