A-Tech 64GB (8x8GB) DDR3 1866 ECC RDIMM 2Rx4 1.5V 240-Pin server RAM

SKU CH-Z52H-9Y7TS

An 8-module 64 GB DDR3 1866 MHz ECC registered server kit running at 1.5 V with CL13 latency

  • Total capacity64 GB (8 × 8 GB)
  • Rated speedDDR3 1866 (PC3 14900)
  • ChipsetMajor Brand Chipset
  • CAS latencyCL13
  • Rated voltage1.5 V

Capacity 64GB (8 x 8GB)

  • 64 GB capacity across eight modules handles heavy server workloads
  • DDR3 1866 MHz speed accelerates data throughput for demanding applications
  • ECC registered design detects and corrects memory errors automatically
  • Dual-rank x4 organisation maximises density per DIMM slot
  • 5 V standard voltage ensures broad DDR3 platform compatibility

Server memory kit for DDR3 platforms

This 64GB kit contains eight 8GB registered ECC modules built for servers and workstations that require DDR3 1866 registered DIMMs. The dual-rank x4 organisation and CL13 latency suit multi-socket boards that populate all memory channels. It will not work in desktop or laptop systems that accept only unbuffered memory. ||

Capacity and headroom for virtualised workloads

Sixty-four gigabytes spread across eight modules fills eight DIMM slots and lets a compatible platform run several virtual machines or large in-memory databases simultaneously. Workloads that exceed 64GB or demand higher memory bandwidth than DDR3 1866 provides will need a newer platform with faster memory technology. ||

Thermals and power at standard voltage

The modules operate at the standard 1.5V DDR3 voltage, so power draw stays within the limits defined for registered DIMMs of this speed. Registered buffering reduces electrical loading on the memory controller, helping stability in fully populated configurations. Adequate chassis airflow keeps module temperatures within specification during sustained use.

Questions about this item

Will these 1866 MHz DDR3 RDIMMs run at the rated 1866 speed in a server that officially supports 1866 MHz modules?

Yes, the kit is rated for DDR3 1866 (PC3-14900) with CL13 timing at 1.5 V; if your platform supports that speed the modules will operate at 1866 MHz.

How can I confirm the 64 GB ECC registered kit is recognised and error-correcting after installation?

Enter the system BIOS or UEFI and verify the total installed memory shows 64 GB, the speed reads 1866 MHz, and ECC or Registered status is reported as enabled.

Does the box contain eight individual 8 GB RDIMMs or do I need to buy any modules separately to reach 64 GB?

The kit ships as eight 8 GB DDR3 240-pin ECC RDIMMs, providing the full 64 GB capacity with nothing else required.
