NEMIX RAM 128GB (4x32GB) DDR5 5200 CL38 1.1V 2Rx8 UDIMM memory upgrade

128GB DDR5 kit for Supermicro workstations

This 128GB kit contains four 32GB DDR5 5200 unbuffered UDIMM modules rated at CL38 and 1.1V. It is built for Supermicro desktop and SuperWorkstation platforms such as the MBD-C9Z790-CGW motherboard. The modules use major OEM chips from Samsung, Micron or Hynix and operate without ECC or heat spreaders. Builders expanding memory on these validated boards can install the kit directly into the 288-pin slots.

Standard voltage and unbuffered design keep

Running at the DDR5 base voltage of 1.1V, the modules draw minimal power during typical desktop and workstation workloads. With no heat spreader attached, airflow across the bare PCB is sufficient for normal operation in a chassis with adequate case cooling. The unbuffered topology adds no extra electrical load, so system fan curves remain unchanged for everyday tasks.

Sustained workloads stay within JEDEC limits

Under continuous multi-threaded loads the kit maintains its rated 5200 MT/s speed and CL38 latency at 1.1V. The 2Rx8 organisation distributes density across ranks, allowing the memory controller to sustain bandwidth without exceeding the standard voltage envelope. Because the modules are validated for the target Supermicro platforms, no manual timing adjustments are required to achieve stable long-duration performance.
