Four green 288-pin DDR4 server DIMMs with black chips no heat spreader

A-Tech

A-Tech 256GB (4x64GB) DDR4 2133 ECC RDIMM 2S4Rx4 Server RAM

SKU CH-QE18-2572M

Quad-channel kit of four 64 GB DDR4-2133 ECC registered DIMMs for server and workstation memory expansion

  • Capacity256GB (4 x 64GB)
  • Type288-Pin DDR4 SDRAM
  • SpeedDDR4 2133 (PC4 17000)
  • CAS LatencyCL15
  • Voltage1.20V
  • ECCYes

Capacity 256GB (4 x 64GB)

  • 256GB capacity handles heavy server workloads using four 64GB modules
  • ECC registered design protects data integrity in mission-critical systems
  • DDR4 2133 speed delivers responsive performance for multi-threaded applications
  • Octal-rank 3DS/TSV architecture maximises density within 288-pin form factor
  • 20V operation reduces power draw while maintaining stability

Server Memory Kit

This A-Tech kit delivers 256GB of DDR4 memory across four 64GB registered DIMMs. It is built for servers and workstations that require ECC error correction and registered signal buffering. Desktop and laptop systems cannot use these modules.

Capacity and Headroom

The quad-channel configuration provides 256GB total capacity at DDR4 2133 speed with CL15 latency. It handles large virtualisation clusters, in-memory databases and heavy multi-user workloads. Systems limited to lower maximum memory per slot or lacking 3DS/TSV support will not recognise the full capacity.

Thermals Noise and Power

Modules operate at the standard 1.20V DDR4 voltage without integrated heat spreaders. Registered buffering reduces electrical load on the memory controller during sustained throughput. Adequate chassis airflow is required to maintain stable temperatures under continuous server loads.

Preguntas sobre este artículo

Will these 288-Pin DDR4 2133 ECC RDIMM modules work with my existing 1.20V DDR4 registered memory?

Yes, they match the 1.20V DDR4 standard and registered ECC design, so they can operate alongside identical spec modules.

How can I confirm the 256GB kit is running at CL15 after installation?

Check the BIOS memory info or a tool like CPU-Z; it should show DDR4 2133 speed with CL15 timings on all four 64GB sticks.

Does the quad-channel kit include only the four 64GB RDIMMs, or are heat spreaders and cables supplied?

The box contains the four 288-Pin ECC RDIMM modules only; no heat spreaders or extra cables are included.
