OWC 1R3D32R4032P 32GB (2x16GB) DDR3 1333 ECC RDIMM

Server-grade ECC memory kit

This 32GB kit contains two 16GB DDR3 1333 registered DIMMs built for Supermicro X8DA6, X8DAE, X8DAH+, X8DAL and X8DT3 series motherboards. Each module runs at 1.5V with CL9 latency and 2Rx4 organisation. ECC and register logic protect data integrity in workstation, server, NAS and router roles. The 240-pin form factor fits only DDR3 slots designed for registered memory.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller, allowing the pair to maintain stable throughput during long compute jobs or virtualisation workloads. ECC correction handles single-bit errors without halting the system. The 1333MHz data rate and CL9 timing deliver consistent bandwidth rather than peak burst speed. Heat spreaders are absent, so airflow across the DIMMs remains important in dense chassis.

DDR3 platform limits

DDR3 1333 caps theoretical bandwidth at PC3-10600, which is lower than later DDR generations. Registered DIMMs cannot be mixed with unbuffered modules on the same channel. The kit targets the listed Supermicro platforms only; it will not work in standard desktop boards or laptops that expect unbuffered DDR3. Capacity per slot is limited to the 16GB density of these modules.
