NEMIX RAM

NEMIX RAM 16GB DDR4 2133 ECC Unbuffered UDIMM CL15 288-PIN memory upgrade

SKU CH-TKK5-3J327

16 GB DDR4 ECC unbuffered UDIMM running at 2133 MHz with CL15 latency for compatible workstation systems

  • Capacity16GB
  • SpeedDDR4 2133 (PC4 17000)
  • ECCYes
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • ECC protection prevents data errors in critical workloads
  • 16 GB capacity adds headroom for demanding applications
  • 2133 MHz DDR4 speed supports responsive multitasking
  • CL15 latency keeps access times low
  • 2 V operation reduces power draw and heat

Compatible Workstation Upgrade

This 16GB DDR4 module is built for Hynix-based servers and workstations that require ECC unbuffered memory. It targets IT professionals maintaining qualified platforms where data integrity matters. The single-stick design suits slots that accept a 2Rx8 rank configuration. Buyers needing registered DIMMs or non-ECC consumer memory should look elsewhere.

Physical Fit and Signal Integrity

The 288-pin UDIMM form factor matches standard DDR4 desktop and workstation sockets. Operating at 1.2V reduces power draw and heat without a spreader. Gold contacts are stress-tested under load to ensure reliable seating. Systems limited to 204-pin DDR3 SO-DIMM slots cannot use this module.

Speed and Latency Gate

Rated at 2133 MT/s with a CL15 timing, the module delivers PC4-17000 bandwidth. The memory controller must support this exact data rate and latency for stable operation. Platforms requiring higher frequencies or lower CAS values will not benefit from this part.

  • 16 GB capacity adds headroom for demanding applications
  • 2133 MHz DDR4 speed supports responsive multitasking

Questions about this item

Does this DDR4 2133 module run at the full PC4-17000 data rate on a standard UDIMM slot?

Yes, the module is rated DDR4 2133 (PC4-17000) and will operate at that speed on any compatible unbuffered DDR4 UDIMM slot.

Will the 288-pin UDIMM with no heat spreader fit in a standard workstation DIMM socket?

Yes, it uses the standard 288-pin UDIMM form factor and has no heat spreader, so it fits any regular DDR4 DIMM socket without clearance issues.

What is the correct way to seat this ECC unbuffered UDIMM, and what step do people often miss?

Align the notch with the socket key, press firmly until both side clips click shut, and verify the module is fully vertical — partial insertion is the common mistake.
