Server memory kit

This OWC kit supplies 64GB of DDR3L ECC registered memory across eight 8GB modules. It is built for Cisco UCS B260 M4 and B460 M4 blade servers running E7 v2 or v3 processors.

240-pin registered DIMMs

Each module uses the 240-pin DDR3L form factor at 1.35V with a 2Rx4 organisation. The registered buffer and ECC function require a server chipset that supports registered memory; they will not work in standard desktop boards or alongside unbuffered or load-reduced DIMMs.

Sustained operation at CL11

Rated at 1600MHz with CL11 latency, the modules deliver consistent throughput for virtualisation and database workloads. JEDEC and RoHS compliance ensures stable voltage regulation during extended duty cycles in dense blade chassis.

Questions about this item

What is the CAS latency of these DDR3L 1600 modules?

The modules run at CL11 latency as specified in the DDR3L 1600 PC3L-12800 rating.

How much power do the eight registered DIMMs draw at 1.35 V under continuous load?

Each 8 GB module operates at 1.35 V; the registered design and ECC logic keep per-module power low during sustained server workloads.

Which Cisco UCS blade servers must the chassis already support for this 64 GB kit to work?

The kit is validated for Cisco UCS B260 M4 E7 v2 & v3 and B460 M4 E7 v2 & v3 blade servers.
