Two green DDR4 UDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 32GB (2x16GB) DDR4 2933MHz CL21 1.2V 288-pin UDIMM memory upgrade

SKU CH-6EZV-SMHS4

A 32 GB DDR4-2933 dual-rank kit (2 × 16 GB, CL21, 1.2 V) built for SuperMicro workstations

  • Capacity32GB (2 x 16GB)
  • SpeedDDR4 2933 (PC4 23400)
  • ECCNo
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • 32 GB kit expands workstation capacity
  • DDR4 2933 MT/s supports demanding server workloads
  • CL21 latency keeps data flowing smoothly
  • 20 V operation reduces power draw
  • Validated for Supermicro 5039AD-I and C9X299-PGF systems

Capacity and fit

This 32 GB kit contains two 16 GB DDR4 UDIMMs rated at 2933 MHz with CL21 timings and 1.2 V operation. The modules are non-ECC, unbuffered and use a 1Rx8 organisation on a 288-pin interface. They are validated for the Supermicro SuperWorkstation 5039AD-I, C9X299-PGF and CSE-GS5A-754K platforms.

Upgrade path

The kit replaces lower-capacity or slower DDR4 memory in compatible Supermicro workstations and servers. The jump is worthwhile when the workload exceeds the current memory ceiling or when the existing modules run below 2933 MHz, allowing the platform to operate at its rated data rate without overclocking.

Sustained operation

All modules undergo stress testing under load to verify stability during extended compute tasks. The absence of a heat spreader means airflow across the PCB is the primary cooling method; ensure the chassis provides adequate circulation. The 1.2 V rating keeps power draw modest during continuous use.

Questions about this item

What motherboard slot and pin count does this 288-pin DDR4 UDIMM kit require?

The kit uses standard 288-pin DDR4 UDIMM slots on a compatible Supermicro motherboard such as the SuperWorkstation 5039AD-I or MBD-C9X299-PGF.

How are the two 16 GB modules installed, and what step is often missed?

Insert each module into the correct colour-coded DDR4 channel slots until the retention clips click; the step often missed is populating the slots in the motherboard's recommended channel order for dual-channel operation.

When will these non-ECC unbuffered modules need replacement?

They have no heat spreader and no moving parts, so replacement is only needed if a module fails or system memory requirements exceed the 32 GB kit capacity.
