Speed DDR3 1600 (PC3 12800)

  • 64 GB kit expands server capacity for heavier workloads
  • ECC RDIMM detects and corrects memory errors automatically
  • Registered DDR3 1600 MHz modules deliver 12800 MT/s throughput
  • Dual-rank 2Rx4 organisation increases density per DIMM slot
  • 5 V standard voltage matches DDR3 server specifications

Kit capacity and target platform

This 64GB kit contains eight 8GB DDR3 registered DIMMs built for servers and workstations that require ECC memory. It is not compatible with standard desktop or laptop computers. The modules use a 240-pin form factor and operate at the standard 1.5V DDR3 voltage.

Sustained-load behaviour

Registered buffering and ECC error correction keep data integrity intact during continuous, multi-threaded workloads. Dual-rank x4 organisation allows the memory controller to interleave accesses across ranks, maintaining steady throughput under heavy virtualisation or database tasks. CL11 latency at 1600 MHz delivers predictable response times without voltage scaling.

Compatibility checks before ordering

Verify that your system supports DDR3 registered ECC RDIMMs and accepts 2Rx4 modules in the planned slot population. Confirm the maximum supported capacity per channel and the required memory seating order from the motherboard manual. Ensure the platform does not require load-reduced or unbuffered DIMMs instead.

Questions about this item

How much power does the 1.5V DDR3 1600 kit draw when the server runs continuously?

Each module operates at the standard 1.50V DDR3 voltage. Total system power depends on the platform's memory controller and how many of the eight slots are populated.

What must the system already provide for these 240-pin registered ECC modules to function?

A DDR3 server or workstation motherboard that supports registered ECC RDIMMs, 240-pin DIMM slots, and the PC3-12800 speed grade. Desktop or laptop boards will not work.

Can the 2Rx4 dual-rank modules share channels with existing single-rank DDR3 1600 RDIMMs?

Mixing ranks on the same channel is platform-dependent. Consult the system manual for supported rank-per-channel configurations and population rules before adding this kit.
