Eight green DDR3 DIMMs with black chips and silver labels

A-Tech

A-Tech 256GB (8x32GB) DDR3 1333 ECC RDIMM 4Rx4 Server RAM

SKU CH-K47D-XPC1D

Eight 32 GB DDR3 1333 ECC registered modules provide 256 GB of quad-rank server memory at 1.5 V

  • Capacity256GB (8 x 32GB)
  • SpeedDDR3 1333 (PC3 10600)
  • CAS LatencyCL9
  • Voltage1.50V
  • ECCYes
  • Buffered/RegisteredRegistered

Capacity 256GB (8 x 32GB)

  • 256 GB total capacity from eight 32 GB modules
  • DDR3 1333 MHz speed with CL9 latency for responsive server workloads
  • ECC registered design detects and corrects data errors automatically
  • Quad-rank 4Rx4 organisation maximises density per DIMM slot
  • 5 V standard DDR3 voltage ensures broad platform compatibility

Kit Capacity and Target Platform

This 256 GB kit contains eight 32 GB DDR3 ECC RDIMM modules built for registered server and workstation platforms only. It will not function in desktop or laptop systems that require unbuffered memory.

Sustained Load Behaviour

Registered buffering and ECC protect data integrity during continuous multi-threaded workloads, while 1.5 V operation keeps power draw predictable across all eight modules under extended uptime.

Installation Notes

Each 240-pin DIMM must be seated in the correct channel order specified by the system manual; mixing quad-rank 4Rx4 modules with other ranks or exceeding the platform's maximum supported capacity per channel will prevent boot.

Questions about this item

How much power does the 1.5V DDR3 1333 kit draw when the server runs continuously?

Each 32GB module operates at the standard DDR3 voltage of 1.5V; total system draw depends on the platform's memory controller and how many of the eight DIMM slots are populated.

What motherboard features are required to use these 4Rx4 registered ECC DIMMs?

The board must support DDR3 registered ECC memory, accept 240-pin DIMMs, and be qualified for quad-rank x4 modules at 1333 MHz.

Will these quad-rank modules work alongside older dual-rank DDR3 RDIMMs already installed?

Mixing 4Rx4 and 2Rx4 or 2Rx8 DIMMs is platform-dependent; consult the server vendor's memory population rules before combining ranks.
