192GB DDR5 ECC UDIMM Kit

This NEMIX RAM kit provides 192GB of DDR5 memory across four 48GB modules. It is built for servers and workstations that require error-correcting code (ECC) protection. The modules operate at 4800MHz with a CL40 latency and a low 1.10V voltage. Unbuffered design suits compatible motherboards without registered memory support.

2Rx8 Organization and Major OEM Chips

Each 48GB module uses a 2Rx8 rank configuration built with Samsung, Micron, or Hynix components. The 288-pin UDIMM form factor fits standard DDR5 slots on supported platforms. ECC functionality corrects single-bit errors to maintain data integrity under heavy workloads. No heat spreaders are included, relying on system airflow for cooling.

Suits High-Capacity Server and Workstation Builds

This kit targets administrators upgrading memory in ECC-capable servers, NAS units, or workstations. Buyers needing registered RDIMM or LRDIMM modules for specific server platforms should verify motherboard requirements first. Systems limited to lower maximum capacities or non-ECC consumer memory will not support this configuration. Always consult the system manual for qualified memory lists.

Questions about this item

Will the 48 GB DDR5 ECC UDIMM modules need a heat spreader added later for sustained server loads?

The modules ship without a heat spreader; adequate case airflow is the only cooling they rely on.

What limits continuous throughput first — the CL40 latency or the 4800 MT/s data rate?

The 4800 MT/s data rate sets the peak bandwidth ceiling; CL40 latency determines response time, not sustained throughput.

How much power does the 192 GB kit draw at the rated 1.10 V when running all day?

At 1.10 V the four 48 GB modules draw minimal power; exact wattage varies with workload but stays well within standard DDR5 UDIMM limits.
