Capacity 384GB (12 x 32GB)

  • 384 GB total capacity from twelve 32 GB modules
  • Registered ECC design protects data integrity under load
  • DDR3 1600 speed with CL11 latency for responsive throughput
  • Low 1.35 V operation reduces power draw and heat

384GB DDR3 ECC RDIMM Kit

This 384GB kit contains twelve 32GB DDR3 1600 registered DIMMs built for servers and workstations that require ECC protection. The 4Rx4 organization and 1.35V operation suit high-density memory configurations in enterprise environments.

DDR3 1600 registered limits

DDR3 1600 tops out at PC3-12800 bandwidth and the registered buffer adds one cycle of latency versus unbuffered modules. Maximum capacity per channel depends on the motherboard memory controller and BIOS revision.

Upgrading from smaller DDR3 kits

Replacing lower-capacity DDR3 RDIMMs with this 384GB kit removes the need to populate every slot with smaller modules. The jump is worthwhile when the platform supports 4Rx4 ranks and the workload demands the full 384GB address space.
