Four green DDR4 UDIMM sticks with gold contacts and black heat spreaders, 288-pin each

A-Tech

A-Tech 128GB (4x32GB) DDR4 2666 ECC UDIMM 2Rx8 CL19 1.2V Server RAM

SKU CH-56AK-7DJ67

Four 32 GB DDR4 ECC UDIMM modules totalling 128 GB at 2666 MHz with CL19 latency and 1.2 V operation for compatible servers and workstations

  • CAS LatencyCL19
  • Rank2Rx8
  • 128 GB total capacity from four 32 GB modules
  • DDR4 2666 MHz speed for faster data throughput
  • ECC unbuffered design detects and corrects memory errors
  • Dual rank 2Rx8 organisation increases memory density
  • Standard 1.2 V DDR4 voltage reduces power draw

Server ECC Kit for Demanding Workloads

This 128GB kit contains four 32GB DDR4 ECC UDIMM modules built for servers and workstations that require error-correcting memory. It is not compatible with standard desktop or laptop computers.

2Rx8 Dual Rank Determines Compatibility

Each module uses a 2Rx8 dual-rank organisation that the system memory controller must support. Verify that your platform accepts this rank structure before ordering, as mismatched ranks will prevent boot or reduce capacity.

Simple DIMM Installation With Channel Rules

The 288-pin DIMMs install in standard DDR4 slots, but population order matters for multi-channel operation. Follow the system manual for correct slot sequence; incorrect seating or channel placement is the most common cause of unrecognised memory.
