Server memory kit for enterprise systems

This OWC kit delivers 64 GB of DDR3L registered ECC memory across eight 8 GB modules. It targets administrators upgrading workstations, servers, NAS appliances or routers that require 240-pin DDR3L RDIMMs. The kit is not suitable for standard desktop computers or any platform that accepts only unbuffered memory.

DDR3L 1333 registered interface limits

The modules operate at 1333 MHz with a CL9 latency and a 1.35 V supply. Registered buffering adds one clock cycle of address/command delay, which is mandatory for the target platforms but prevents use in consumer boards that expect unbuffered DIMMs. Mixing these sticks with unbuffered memory is not supported and will cause instability.

Capacity headroom for multi-socket workloads

Eight modules provide 64 GB total, allowing population of all slots in many dual-channel server boards. The 2Rx4 organisation keeps electrical loading low per channel, helping signal integrity at full capacity. Systems that require more than 64 GB or faster than 1333 MHz will need a different memory generation or higher-density modules.

Perguntas sobre este artigo

Should I choose the 64 GB kit with eight 8 GB modules or a smaller capacity for my server?

The kit provides 64 GB total across eight 8 GB DDR3L 1333 registered DIMMs. Use all eight slots for maximum capacity or populate fewer slots if your platform limits total memory or requires specific slot filling rules.

What does the 1333 MHz speed mean for actual throughput in a workstation?

At DDR3L 1333 (PC3L-10600) the modules deliver up to 10 600 MB/s peak bandwidth per channel. Real-world throughput depends on your CPU memory controller, channel population and BIOS settings.

How does the 240-pin DDR3L registered ECC interface limit compatibility?

These 240-pin DDR3L 1.35 V registered ECC RDIMMs only fit servers, workstations, NAS units or routers that explicitly support registered DDR3L memory. They will not work in standard desktop boards or unbuffered DDR3 slots.
