OWC 64GB DDR3L ECC RDIMM kit

This OWC kit supplies 64 GB of DDR3L memory as eight 8 GB registered DIMMs. Each module runs at 1600 MHz with CL11 latency and operates at 1.35 V. The 240-pin form factor and ECC registered design target Cisco UCS B250 M2 and C250 M2 servers.

Suits Cisco UCS B250 M2 and C250 M2 upgrades

IT teams maintaining these Cisco platforms can populate all slots with matched 2Rx4 modules for error-correcting capacity. The registered design and 1.35 V operation prevent use in standard desktop boards or consumer laptops. Buyers needing unbuffered memory or a different pin count should select another kit.

Registered ECC at 1.35 V decides fit

The modules are ECC registered DDR3L RDIMMs keyed for 1.35 V operation. Systems that require unbuffered DIMMs, load-reduced DIMMs, or 1.5 V DDR3 will not accept these parts. Verify the server manual calls for registered ECC DDR3L before ordering.

Questions about this item

Should I pick the 64GB kit or build the same capacity from smaller kits?

The 64GB kit ships as eight matched 8GB modules tested together for Cisco UCS B250 M2 and C250 M2 servers, so you avoid mixing batches.

What does the PC3L-12800 1600MHz rating deliver inside a Cisco UCS server?

It runs at 1600MHz with CL11 latency at 1.35V, giving registered ECC bandwidth the platform expects for virtualization workloads.

Will the 240-pin DDR3L registered DIMMs work in a standard desktop board?

No — these are 2Rx4 registered ECC modules for workstation and server platforms only; they will not fit or function in unbuffered desktop sockets.
