NEMIX RAM
32 GB DDR5 4800 ECC UDIMM module with CL40 latency and 1.1 V operation for Micron-compatible workstations
This single 32 GB module adds ECC-protected DDR5 memory to compatible Micron workstations and servers. It targets IT professionals who need error-correcting capacity for mission-critical workloads without registered buffering.
The UDIMM fits standard DDR5 slots and operates at 1.1 V, simplifying installation in dense chassis where a spreader would block adjacent modules. Unbuffered signalling keeps latency low for workloads that favour direct memory access.
The module runs at PC5-38400 with a CL40 timing profile, so the platform must support that exact speed and latency combination. Builders whose motherboards require different timings or registered DIMMs cannot use this part.

The module operates at DDR5 4800 MT/s with a CAS latency of CL40, delivering PC5-38400 bandwidth at the standard 1.1 V.
No heat spreader is fitted; the bare PCB uses the standard low-profile DDR5 UDIMM height, so it fits in any 288-pin DDR5 slot without extra clearance.
Align the notch on the 288-pin edge connector with the DDR5 slot key, press firmly until both retention clips click, then verify in BIOS that ECC is enabled — many builders forget that last step.
