NEMIX RAM 128GB DDR4 Server Module

This registered ECC RDIMM provides 128GB of DDR4 memory at 3200MHz with a CAS latency of 22. It is built for enterprise servers that require error correction and registered signalling. The module operates at 1.2V using a 288-pin interface. It is not compatible with standard desktop or laptop computers.

DDR4 3200 Registered ECC Limits

The PC4-25600 standard defines the maximum transfer rate and timing parameters for this module. Registered buffering adds one clock cycle of latency to improve signal integrity across heavily populated memory channels. ECC functionality requires a motherboard and CPU that both support error-correcting code operation. Systems without registered ECC support will not boot with this module installed.

Installing The 4Rx4 RDIMM

Installation follows the standard 288-pin DIMM procedure: align the notch, press firmly until the retention clips engage, and verify seating. The 4Rx4 rank organisation increases electrical load on the memory controller, so population rules in the server manual must be followed exactly. Common issues include mixing registered with unbuffered modules, exceeding the maximum rank count per channel, or using a platform that lacks ECC support.

Questions about this item

Is this single 128 GB module the only capacity option available?

Yes, the kit contains one 128 GB DDR4 3200 MHz registered DIMM.

What does the 3200 MHz rating mean once the module is installed in a server?

The memory runs at 3200 MT/s with CAS latency 22 at 1.2 V, delivering PC4-25600 bandwidth.

How does the DDR4 288-pin RDIMM interface affect compatibility?

The 288-pin registered DIMM fits only server boards that support DDR4 ECC RDIMM; it will not work in standard desktop systems.
