  • 64 GB kit expands server capacity with eight 8 GB modules
  • DDR3 1066 MHz speed accelerates data throughput for demanding workloads
  • ECC registered design detects and corrects memory errors automatically
  • 2Rx4 dual-rank architecture maximises density per DIMM slot
  • 5 V standard voltage ensures broad DDR3 platform compatibility

Server-grade capacity

The A-Tech 64GB kit delivers eight registered DDR3 modules totalling 64GB of ECC memory for compatible servers and workstations. Each 8GB stick runs at 1066MHz with CL7 latency at the standard 1.50V DDR3 voltage. The 2Rx4 dual-rank organisation and 240-pin RDIMM form factor target multi-socket platforms that require registered, error-correcting memory.

Sustained workload behaviour

Registered buffering and ECC circuitry maintain data integrity during continuous, memory-intensive tasks such as virtualisation, database serving or scientific computing. Dual-rank x4 chips allow the memory controller to interleave accesses across ranks, sustaining throughput when all eight slots are populated. Standard 1.50V operation keeps power draw predictable under prolonged load without requiring elevated voltages.

Upgrade scope and limits

This kit replaces smaller DDR3 RDIMM sets or mixed-capacity configurations in systems qualified for PC3-8500 registered memory. The jump is worthwhile when the platform supports eight DIMM slots per processor and the workload benefits from the full 64GB capacity. It does not fit desktop or laptop boards that accept only unbuffered non-ECC DDR3 modules.

Questions sur cet article

How much power does the 1.5 V DDR3 1066 kit draw when the server runs continuously?

Each module operates at the standard DDR3 voltage of 1.5 V; total system draw depends on the platform's memory controller and how many of the eight DIMM slots are populated.

What motherboard feature is required for these 240-pin registered DIMMs to function?

The board must support DDR3 registered ECC memory with a 240-pin DIMM slot and be able to address dual-rank x4 modules at 1066 MHz.

Will these dual-rank x4 modules work alongside older single-rank DDR3 RDIMMs in the same server?

Mixing ranks is platform-dependent; the system manual should confirm whether 2Rx4 modules can share a channel with different-rank DIMMs at 1066 MHz.
