NEMIX RAM 128GB DDR4 Kit

This NEMIX RAM kit supplies 128GB of DDR4 memory in a matched set of four 32GB UDIMM modules. It operates at 2666MHz with CL19 latency and a standard 1.20V voltage. The unbuffered, non-ECC design targets desktop workstations and compatible Supermicro platforms requiring high-density DDR4 upgrades.

Suits Supermicro DDR4 UDIMM builds

Builders populating four DIMM slots on a supported Supermicro desktop or workstation board will find this kit validated for that environment. It is not for systems requiring registered or ECC memory, nor for platforms limited to lower maximum module densities or different DDR generations. Buyers needing error correction or registered signalling must select a different specification.

Check DDR4 UDIMM slot count and CPU support

Verify the motherboard provides four 288-pin DDR4 UDIMM slots and that the installed processor supports 2666MHz operation at this total capacity. Confirm the board accepts 2Rx8 non-ECC unbuffered modules without requiring registered DIMMs. Consult the system manual for approved population rules and maximum memory per channel before ordering.

Questions about this item

What motherboard slot does each 32GB DDR4 2666 CL19 module use?

Each module plugs into a standard 288-pin DDR4 UDIMM slot on the motherboard.

Will these 1.2V CL19 sticks run at rated speed if I keep my existing slower DDR4 modules?

The system will clock all installed DDR4 memory down to the speed of the slowest module present.

How can I confirm the kit is running at 2666 MT/s with CL19 timings after installation?

Check the memory frequency and CAS latency reported in BIOS or a system-information tool such as CPU-Z.
