A-Tech 512GB (8x64GB) DDR4 2666 ECC LRDIMM 4Rx4 Server RAM

SKU CH-PV3E-5KCQ0

Eight 64 GB DDR4 2666 ECC LRDIMM modules deliver 512 GB of quad-rank server memory at 1.2 V

  • Capacity512GB (8 x 64GB)
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V

Capacity 512GB (8 x 64GB)

  • 512 GB total capacity across eight 64 GB modules
  • DDR4 2666 MHz speed with CL19 latency for fast data access
  • ECC load-reduced DIMM technology detects and corrects memory errors
  • 2 V standard DDR4 voltage reduces power draw per module
  • 288-pin quad-rank x4 form factor fits compatible server and workstation slots

Server-grade capacity for heavy workloads

This 512 GB kit delivers eight 64 GB DDR4 2666 modules designed for servers and workstations that require ECC load-reduced memory. It suits administrators expanding virtualisation hosts, database nodes or compute clusters where registered DIMMs are mandatory. Desktop and laptop platforms cannot use these modules.

ECC and load-reduction protect data integrity

Each module implements 4Rx4 quad-rank organisation with on-die ECC, correcting single-bit errors and reducing electrical load on the memory controller. The 1.2 V operating voltage matches the DDR4 standard while the CL19 latency supports stable throughput under sustained multi-threaded workloads.

288-pin DIMM form factor fits qualified platforms

Major-brand chips populate every stick and all units pass A-Tech's validation suite before shipping. Installation follows the system vendor's channel and population rules; the kit is backed by a lifetime warranty and US-based technical support for the product's usable life.

Questions sur cet article

Will the 4Rx4 LRDIMM modules need any firmware updates or re-seating after extended uptime?

The modules ship tested and ready to install; no firmware is involved, and normal server maintenance schedules cover any physical re-seating.

What limits sustained throughput on these 2666 MHz CL19 LRDIMMs?

The DDR4 2666 bus and CL19 latency set the bandwidth ceiling, while the quad-rank organisation maximises density per channel.

How much heat and power do eight 64 GB 1.2 V LRDIMMs add when the server runs all day?

Each module operates at the standard 1.2 V DDR4 voltage, so total power scales with the 512 GB capacity and the server's memory controller efficiency.
