128GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit supplies 128GB of DDR5 4800 memory as two 64GB registered DIMMs. It is built for the Dell Precision 7875 workstation where ECC registered modules are required for system stability. The 2Rx4 organisation and 1.1V operation match the platform specifications.

Sustained load behaviour with CL40 latency

The modules run at CL40 timings under the DDR5 4800 standard, delivering consistent throughput for long compute sessions. ECC correction and registered buffering maintain data integrity when the workstation processes large datasets or runs virtualised workloads for extended periods. Samsung, Micron or Hynix components provide the underlying reliability.

Straightforward installation in approved slots

The 288-pin RDIMMs seat directly into the Precision 7875 memory slots without extra configuration. Builders who need more than 128GB or who use a non-ECC platform cannot use this kit. Always follow the Dell service manual for correct population order and firmware settings.

Questions about this item

How much power does the 128GB DDR5 4800 kit draw at its 1.1V rating?

The kit runs at 1.1V, the standard DDR5 voltage, keeping power draw low for a 128GB registered ECC configuration.

What must the Dell Precision 7875 already have to accept this 2Rx4 RDIMM kit?

The workstation needs free 288-pin DDR5 RDIMM slots and a BIOS that supports registered ECC memory at 4800 MT/s.

Will the CL40 4800 modules run correctly if I keep slower DDR5 RDIMMs in the other channels?

All installed DDR5 RDIMMs will operate at the speed of the slowest module, so the 4800 CL40 kit will downclock to match older modules.
