Four green DDR5 UDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 64GB (4×16GB) DDR5-5600 ECC UDIMM CL46 1.1V 288-pin memory upgrade

SKU CH-SJSS-G39ZZ

64 GB (4 × 16 GB) DDR5-5600 ECC unbuffered UDIMM kit at 1.1 V, CL46, 288-pin for Supermicro X14SAE

  • Total capacity64 GB (4 × 16 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeUnbuffered

Size 64GB 4X16GB

  • ECC corrects single-bit errors preventing silent data corruption and crashes
  • 64GB kit as four 16GB modules maximises capacity on four slots
  • DDR5-5600 CL46 1.10V matches the memory controller's exact timing and voltage
  • 288-pin unbuffered UDIMM form factor fits Supermicro X14SAE motherboard requirements
  • Major OEM Samsung Micron Hynix chips ensure consistent quality and reliability

Exact-match DDR5-5600 ECC kit for Supermicro X14SAE

This 64 GB kit delivers four 16 GB DDR5-5600 UDIMMs built to the precise 1Rx8 unbuffered ECC specification the Supermicro X14SAE motherboard expects. It installs at the rated PC5-44800 speed without manual tuning so workstations and entry servers gain error-correcting capacity immediately.

Thermals noise and power at 1.1 V

Operating at 1.10 V the modules draw minimal power and run without heat spreaders or active cooling. The low voltage keeps system thermals stable and fan noise low during sustained compile jobs virtualisation workloads or database tasks typical of this platform.

Replaces slower or non-ECC DDR5 UDIMMs

The jump is worth it when your current kit lacks ECC runs below 5600 MT/s or uses mixed ranks that force the controller to down-clock. Buyers who need registered DIMMs SODIMMs or capacities beyond four slots should look elsewhere.

Questions about this item

How do I install the four 288-pin DDR5 UDIMMs on the Supermicro X14SAE and which slot order does the manual specify?

Power down and unplug the system. Open the chassis and locate the four DDR5 UDIMM slots. Align each module's notch with the slot key, press firmly until both latches click, then follow the motherboard manual's exact population sequence for 1Rx8 modules to ensure full 64GB recognition at 5600MHz.

Will the ECC UDIMMs need any firmware updates or periodic replacement to maintain error correction?

The modules operate at 1.1V with Samsung, Micron or Hynix DRAM and have no heat spreader. ECC correction is handled by the memory controller; no firmware updates are required for the DIMMs themselves. Replace a module only if the system logs uncorrectable errors or a DIMM fails POST.

What is the first limit reached under sustained load with CL46 latency and 1.1V operation?

The primary limit is the CAS latency of CL46 at 5600MHz, which sets the minimum access delay. The fixed 1.1V JEDEC voltage prevents further frequency scaling, so sustained throughput is bounded by the rated 5600MT/s data rate and the 1Rx8 rank organisation.
