Four green DDR4 ECC UDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 128GB (4 x 32GB) DDR4 2933MHz ECC UDIMM memory upgrade

SKU CH-KASY-Y18ZX

128 GB DDR4-2933 ECC UDIMM kit (4 × 32 GB, CL21, 1.2 V, 2Rx8) validated for Supermicro X12SAE and X12SCA-F motherboards

  • Capacity128GB (4 x 32GB)
  • Type288-Pin DDR4 ECC UDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.20V
  • ECCYes

Size 128GB 4X32GB

  • 128 GB kit lets workstations handle large datasets
  • ECC protection corrects single-bit errors automatically
  • DDR4 2933 MHz matches Supermicro X12SAE and X12SCA-F specs
  • Unbuffered 288-pin UDIMM installs directly in motherboard slots
  • 2 V CL21 2Rx8 modules run at rated speed without tuning

Exact-fit DDR4 ECC kit for Supermicro

This 128 GB kit provides four 32 GB DDR4 2933 MHz ECC unbuffered UDIMMs built to the precise rank, voltage and timing the Supermicro X12SAE and X12SCA-F motherboards expect. It is aimed at administrators and workstation builders who need verified, full-capacity operation on those specific platforms without manual tuning.

Thermals and power draw

Each module runs at 1.2 V with no heat spreader, so power draw stays low and thermal output is minimal under normal server or workstation loads. Passive cooling in a chassis with adequate airflow is sufficient; the sticks add no audible noise because they have no moving parts.

288-pin unbuffered ECC UDIMM form factor

The kit uses the 288-pin unbuffered ECC UDIMM layout required by the target Supermicro boards; RDIMM or SODIMM modules will not fit or function. Buyers whose systems demand registered DIMMs or a different pin count should look elsewhere.

Questions sur cet article

How do I install the 288-pin DDR4 ECC UDIMM modules in the correct population order on my Supermicro X12SAE motherboard?

Power down, open the chassis, consult the motherboard manual for the approved DIMM sequence, then press each 288-pin UDIMM firmly into its slot until the retention clips click — skipping the manual's population order is the step most often missed and can prevent full 128GB recognition.

What maintenance or replacement will the 1.20V Samsung, Micron or Hynix DRAM chips need during their service life?

No routine maintenance is required for the DRAM chips; if a module fails it is replaced as a unit under the lifetime replacement warranty.

At what point does the CL21 latency limit sustained throughput on this 2933MHz kit?

CL21 sets the minimum row-access delay, so under continuous heavy workloads the CAS latency becomes the first timing bottleneck before bandwidth or voltage limits are reached.
