Eight green DDR4 UDIMM sticks in a row

NEMIX RAM

NEMIX RAM 256GB (8x32GB) DDR4 2666 ECC UDIMM server RAM

SKU CH-K17A-Y445T

Eight unbuffered DDR4 ECC UDIMMs deliver 256 GB at 2666 MHz with CL19 latency and 1.2 V operation

  • Capacity256GB (8 x 32GB)
  • Type288-Pin DDR4 ECC UDIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes

Capacity 256GB (8 x 32GB)

  • 256GB total capacity across eight 32GB modules
  • DDR4 2666 speed with CL19 latency for responsive server workloads
  • ECC unbuffered design protects data integrity in mission-critical systems
  • 2V operation reduces power draw across large memory arrays
  • Built with major OEM chips and stress-tested for enterprise reliability

256GB DDR4 ECC UDIMM Kit

This 256GB kit contains eight 32GB DDR4 2666 ECC UDIMM modules rated at PC4-21300 with CL19 latency. It runs at 1.2V on a 288-pin interface and uses 2Rx8 organisation with chips from major OEM suppliers. The kit targets servers and workstations that require error-correcting memory for data integrity.

Suited for ECC-capable boards only

The modules are unbuffered ECC UDIMMs, so they need a motherboard and CPU that explicitly support unbuffered ECC operation. Systems that require registered or load-reduced DIMMs cannot use this kit. Builders needing higher speeds, lower latency or non-ECC memory should look at other configurations.

Straightforward DIMM installation

Installation follows standard UDIMM procedure: power down, open the chassis, align the notch with the slot key and press until the latches click. Common issues arise when the platform does not support unbuffered ECC or when the BIOS is not configured to enable ECC, causing the system to ignore the modules or fail to boot.

Soalan tentang produk ini

Does my motherboard need 288-pin DDR4 slots and support for ECC unbuffered UDIMMs to run this 256 GB kit?

Yes — the kit uses 288-pin DDR4 ECC unbuffered UDIMM modules, so the board must provide DDR4 slots that accept ECC unbuffered memory.

Can I keep my existing DDR4 2666 CL19 ECC UDIMMs and add these 32 GB modules to reach 256 GB total?

If the board supports the combined capacity and rank count, mixing same-speed CL19 2Rx8 modules usually works; verify the motherboard’s maximum DIMM population and rank limits first.

How do I confirm the kit is running at DDR4 2666 with ECC active after installation?

Check the BIOS memory information or an OS tool such as dmidecode — it should report 2666 MT/s, CL19 timings, 1.20 V and ECC enabled for each 32 GB module.
