Four green 288-pin DDR5 UDIMM modules in a kit

NEMIX RAM

NEMIX RAM 64GB (4x16GB) DDR5-4800 CL40 1Rx8 1.1V UDIMM Supermicro X14SAE

SKU CH-8W8Z-AX81A

A 64 GB DDR5 kit of four 16 GB UDIMM modules running at 4800 MHz CL40 1.1 V, validated for the Supermicro X14SAE motherboard

  • Total capacity64 GB (4 × 16 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Rated voltage1.1 V
  • Buffer typeUnbuffered

Size 64GB 4X16GB

  • 64 GB capacity from four 16 GB modules for high-density desktop workloads
  • DDR5 4800 speed with CL40 timing delivers rated bandwidth without manual tuning
  • 1 V operation matches the motherboard memory controller specification exactly
  • 288-pin UDIMM form factor fits the Supermicro X14SAE slot and population rules
  • Major OEM Samsung Micron Hynix chips tested for stability at rated speed and voltage

System-Specific DDR5 Kit

This 64 GB kit contains four 16 GB UDIMM modules built for the Supermicro X14SAE motherboard. It delivers the exact rank, voltage and timing the board's memory controller expects for full-capacity recognition.

DDR5-4800 Interface Limits

The modules run at the standard DDR5-4800 (PC5-38400) data rate with CL40 latency at 1.1 V. This JEDEC baseline speed is fixed; the kit does not support XMP or higher factory profiles.

64 GB Capacity Headroom

Four populated slots provide 64 GB of non-ECC unbuffered memory for multi-threaded workloads and large datasets. The board's four-slot maximum is reached, so further expansion requires a platform change.

Questions about this item

Should I choose the 64GB kit or a different capacity for my Supermicro X14SAE?

This kit provides 64GB total in four 16GB modules. Check your motherboard manual for the maximum supported capacity and the approved DIMM population order before deciding.

What does DDR5-4800 CL40 mean for actual system performance?

The modules run at 4800 MT/s with a CAS latency of 40 cycles at 1.10V, giving the bandwidth and timing the X14SAE memory controller expects for stable operation at rated speed.

Is the 288-pin UDIMM interface the right fit for the X14SAE, and does it limit speed?

Yes, the 288-pin unbuffered UDIMM form factor matches the X14SAE slots. The kit is spec-matched to the board's DDR5-4800 (PC5-38400) standard, so the interface does not cap the rated speed.
