Four green DDR4 ECC UDIMM sticks in a 64GB kit

A-Tech

A-Tech 64GB (4x16GB) DDR4 2666 CL19 ECC UDIMM 2Rx8 1.2V 288-Pin Server RAM

SKU CH-57P9-WANS8

Four 16 GB DDR4 ECC UDIMM modules running at 2666 MHz CL19 add 64 GB of dual-rank server memory at 1.2 V

  • CAS LatencyCL19
  • Rank2Rx8
  • 64 GB total capacity from four 16 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 per channel
  • Standard 1.2 V DDR4 voltage reduces power draw

Server DDR4 kit for ECC workloads

This 64 GB kit contains four 16 GB DDR4 2666 MHz ECC UDIMM modules built for servers and workstations that require error-correcting memory. The dual-rank 2Rx8 organisation and CL19 latency suit multi-threaded applications and virtualised environments. Desktop and laptop platforms are not supported.

Steady throughput with error correction

ECC circuitry detects and corrects single-bit errors during continuous operation, protecting data integrity under sustained load. Dual-rank density keeps all channels populated on typical four-slot server boards, maintaining bandwidth without downclocking. Standard 1.2 V DDR4 voltage keeps power draw predictable during long compute runs.

Straightforward DIMM installation

The 288-pin UDIMM form factor seats in any compatible DDR4 ECC UDIMM slot; follow the system manual for correct channel population order. Common issues arise when mixing these modules with non-ECC or registered DIMMs, or when the platform firmware does not support 2Rx8 density. Verify the qualified vendor list before installing.

Questions sur cet article

Does the 1.2 V ECC UDIMM kit run cool and quiet when the server is under constant load?

At 1.2 V the modules use standard DDR4 voltage, so they generate no more heat than any other DDR4 DIMM and have no moving parts to create noise.

What must the system already provide for these 288‑pin DIMMs to function?

The motherboard must support DDR4 ECC Unbuffered memory and have four free 288‑pin DIMM slots.

Will the 2666 MHz CL19 2Rx8 modules run at their rated speed when paired with slower DDR4 memory already installed?

The memory controller will downclock all modules to the speed of the slowest DIMM present.
