Four green DDR4 UDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 32GB 4x8GB DDR4 2933 CL21 1.2V 288-Pin UDIMM memory upgrade

SKU CH-RZDX-KCP6Y

Four unbuffered DDR4 UDIMMs add 32 GB at 2933 MHz CL21 for compatible Supermicro workstations

  • Total capacity32 GB (4 × 8 GB)
  • Rated speedDDR4 2933 (PC4 23400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL21
  • Buffer typeUnbuffered
  • Rated voltage1.2 V
  • 32 GB kit expands system memory for demanding workloads
  • DDR4 2933 MT/s transfers data quickly across the bus
  • CL21 latency keeps response times tight under load
  • 2 V operation reduces power draw and heat output
  • 4 × 8 GB unbuffered UDIMMs install in standard 288-pin slots

32 GB DDR4 kit for Supermicro workstations

This 32 GB kit contains four 8 GB DDR4 2933 UDIMM modules built for Supermicro desktop and SuperWorkstation systems. It targets administrators and builders who need a matched set for multi-channel operation on supported platforms.

Unbuffered non-ECC modules without heat spreaders

Each 288-pin DIMM uses major-brand Samsung, Micron or Hynix chips in a 1Rx8 layout and runs at 1.20 V. The absence of a spreader keeps the profile low for dense chassis, while the unbuffered non-ECC design suits standard workstation boards.

DDR4 2933 CL21 limits bandwidth to PC4-23400

The JEDEC-standard 2933 MT/s rate and CL21 latency cap peak throughput at PC4-23400, so workloads that scale with higher memory clocks will not reach their full potential on this kit. Builders needing faster DDR4 speeds or ECC protection must select a different specification.

Questions about this item

Does the DDR4 2933 interface cap real-world throughput at PC4-23400?

Yes, the kit is rated DDR4 2933 (PC4-23400), so peak bandwidth is limited to that transfer rate.

Will the 288-pin UDIMM modules fit a standard desktop DIMM slot?

They are 288-pin DDR4 UDIMMs, which match the physical keying and length of ordinary desktop memory slots.

How do I install the 1Rx8 sticks, and which step do people miss?

Power down, open the case, align the notch on each 1Rx8 module with the slot key, press firmly until both retention clips click, then verify all four modules are recognised in BIOS.
