Two green DDR4 UDIMM sticks without heat spreaders

NEMIX RAM

NEMIX RAM MD23400-818K2 16GB (2x8GB) DDR4 2933 CL21 1.2V 288-pin UDIMM memory upgrade

SKU CH-DEK4-B65E1

A 16 GB DDR4 2933 kit of two 8 GB UDIMMs with CL21 latency and 1.2 V operation for compatible Supermicro systems

  • Total capacity16 GB (2 × 8 GB)
  • Rated speedDDR4 2933 (PC4 23400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL21
  • Buffer typeUnbuffered
  • Rated voltage1.2 V
  • 16 GB kit boosts multitasking headroom with two 8 GB modules
  • DDR4 2933 MT/s speed feeds data faster to the CPU
  • CL21 latency keeps response tight under load
  • 20 V operation reduces power draw and heat
  • Validated for Supermicro 5039AD-I C9X299-PGF CSE-GS5A-754K workstations

System-Specific DDR4 Kit

This 16 GB NEMIX RAM kit contains two 8 GB unbuffered UDIMM modules rated for DDR4 2933 at CL21 1.20 V. It is built for Supermicro desktop and workstation platforms such as the 5039AD-I and C9X299-PGF where ECC is not required.

Platform Compatibility Check

Verify that your motherboard accepts non-ECC unbuffered DDR4 UDIMMs and supports the PC4-23400 data rate before ordering. The kit targets the listed Supermicro models; other boards may need different ranks, voltages or timings to post reliably.

Sustained Load Behaviour

Modules use major OEM Samsung, Micron or Hynix chips stress-tested under load to maintain stability during extended workloads. Without heat spreaders, adequate chassis airflow is necessary to keep temperatures in check during prolonged operation.

Questions about this item

Does the 16GB kit include both 8GB modules or do I need to buy a second stick?

The package content lists 16GB (2x8GB) as a matched kit, so both modules are included.

Should I choose this DDR4 2933 CL21 kit or a different speed for my Supermicro workstation?

This kit is validated for the Supermicro systems listed, so selecting the exact 2933 MT/s CL21 specification avoids mismatched timing issues.

What does the 2933 MT/s rating deliver once the modules are installed in a Supermicro board?

The modules run at 2933 MT/s with CL21 latency at 1.20V, providing the rated DDR4 bandwidth for the qualified Supermicro platforms.
