OWC 3R2D42R816GB 16GB DDR4 3200MHz ECC RDIMM memory upgrade

SKU CH-VSC5-JXC6E

16 GB DDR4 3200 MHz ECC registered DIMM for select Supermicro server motherboards

  • Capacity16GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.2V
  • ECCYes

Capacity 16GB

  • 16GB capacity expands server memory headroom
  • DDR4 3200MHz speed matches platform requirements
  • ECC registered design protects data integrity
  • 2V operation reduces power draw
  • Validated for five Supermicro H12 motherboards

Server ECC RDIMM upgrade

This OWC 16GB DDR4 3200MHz registered DIMM targets administrators who run Supermicro H12DST-B, H12DSU-iN, H12SSL-C, H12SST-PS or H12SSL-i boards. It delivers ECC protection and registered signalling for workloads that require data integrity. The module operates at 1.2V with CL22 latency and a 2Rx8 organisation.

Replaces Supermicro MEMDR416L series

It substitutes Supermicro part numbers MEMDR416LCL01ER32, MEMDR416LCL02ER32, MEMDR416LCL06ER32, MEM-DR416LD-ER32, MEMDR416LHL01ER32, MEMDR416LHL02ER32 and MEMDR416LSL02ER32. The upgrade is worthwhile when expanding capacity beyond the factory configuration or when a failed stick must be matched for speed and rank. It cannot be mixed with unbuffered memory or used in standard desktop platforms.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors without halting the system, so throughput remains stable during long compute jobs. The absence of a heat spreader means airflow across the 288-pin module must be adequate in densely populated chassis.

Perguntas sobre este artigo

Does the 288-pin DDR4 RDIMM fit the H12SSL-i motherboard slots?

Yes, the 288-pin DDR4 3200MHz ECC RDIMM is listed as compatible with the Supermicro H12SSL-i motherboard.

What is the correct seating method for this registered ECC module?

Align the notch on the 288-pin RDIMM with the slot key, press firmly until both side latches click, and ensure all modules match in capacity, speed and manufacturer.

When should this 16GB CL22 ECC RDIMM be replaced?

Replace the module if memory diagnostics report correctable or uncorrectable ECC errors, or if the server exhibits instability that testing isolates to this DIMM.
