Server ECC RDIMM Kit

This OWC kit supplies 64 GB of DDR5 ECC registered memory in four 16 GB modules. It targets administrators upgrading select workstations, servers, NAS systems or network switches that require registered DIMMs.

Registered Buffer and ECC Impact

The registered buffer reduces electrical load on the memory controller, allowing larger populations per channel. ECC corrects single-bit errors, improving data integrity for critical workloads. The kit cannot be mixed with unbuffered or load-reduced modules.

Platform Verification Required

Confirm that your motherboard or system supports DDR5 288-pin registered RDIMMs at 1.1 V. Verify the qualified vendor list for 5200 MT/s CL42 1Rx8 modules and ensure the CPU memory controller accepts registered ECC.

Points forts

  • 5200 MHz DDR5 speed accelerates demanding workloads
  • 1 V operation reduces power draw per module
  • 64 GB quad-channel kit expands memory capacity

Questions sur cet article

Will the 288-pin DDR5 RDIMMs need any active cooling or heat-spreader replacement over time?

The modules ship without a heat spreader and operate at the standard 1.1 V; no active cooling or spreader replacement is required under normal server airflow.

What is the first latency ceiling you hit when the 5200 MT/s CL42 kit runs continuously?

The JEDEC-rated CAS latency of CL42 is the fixed timing limit; sustained workloads cannot push latency lower than this value.

How much power and heat do the four 16 GB sticks produce when the server runs all day?

Each module draws 1.1 V at DDR5 5200 speeds, so the 64 GB kit stays within standard RDIMM thermal envelopes without extra cooling.
