System-specific DDR5 RDIMM kit

This NEMIX RAM kit delivers 256 GB across two 128 GB modules built to DDR5 6400 MHz CL52 timings. Registered ECC RDIMM architecture with 4Rx4 organisation operates at 1.10 V using major OEM chips. It is validated for the Dell PowerEdge XE9680L rack server.

Suited for Dell PowerEdge XE9680L capacity upgrades

Administrators expanding memory in that specific platform can install this matched pair directly. Systems requiring a different DDR generation, non-ECC unbuffered DIMMs, or a capacity not offered by this kit will need a different part.

Registered ECC RDIMM with 4Rx4 organisation

The registered buffer and on-die ECC combine with quad-rank x4 chip layout to meet the Dell PowerEdge XE9680L memory subsystem requirements. Buyers whose platforms demand unbuffered or single-rank modules cannot use this kit.

Questions about this item

How much power does each 128GB DDR5 6400MHz CL52 4Rx4 module draw at 1.1V in a Dell PowerEdge XE9680L?

Each module operates at 1.1V; DDR5 RDIMM power scales with load and server airflow, so sustained draw depends on the XE9680L's memory subsystem and cooling design.

What must the Dell PowerEdge XE9680L already have to accept this 256GB 288-pin ECC RDIMM kit?

The XE9680L must support DDR5 6400MHz registered ECC 4Rx4 RDIMMs, have two free 288-pin slots, and a BIOS that recognises 128GB-per-DIMM density.

Will this 6400MHz CL52 DDR5 kit run at rated speed beside slower DDR5 modules already in the XE9680L?

All installed DDR5 RDIMMs run at the lowest common speed and latency; mixing slower modules will down-clock this kit to match them.
