Server-grade DDR3L ECC kit

This OWC upgrade kit supplies 64 GB of registered DDR3L memory in eight 8 GB modules. It is built for the Cisco UCS B440 M2 blade server and other workstation or server platforms that require 240-pin ECC registered DIMMs. Standard desktop computers cannot use this memory type.

Registered ECC with low voltage

Each module runs at 1.35 V and meets PC3L-10600 timing at CL9 latency. The registered buffer and ECC circuitry provide the data-integrity and signal-stability that multi-socket server boards demand. Mixing these DIMMs with unbuffered or load-reduced memory is not supported.

64 GB capacity for virtualization workloads

Eight slots filled with 8 GB DIMMs give the B440 M2 its maximum supported memory in this configuration, allowing dense virtual-machine hosting and large in-memory databases. Systems limited to fewer DIMM slots or lower per-slot limits will not accept the full kit.

Questions sur cet article

Will the registered DIMM design or ECC circuitry on these DDR3L modules require any periodic maintenance or replacement?

No, the ECC registered DDR3L modules are solid-state components with no moving parts or serviceable items; they are installed once and remain in place for the life of the server.

What is the first limit reached when the eight 8 GB DDR3L 1333 CL9 modules run at full load continuously?

The memory controller on the Cisco UCS B440 M2 caps usable speed at DDR3L 1333, so bandwidth saturates before voltage or thermal limits become a factor.

How much heat and power do the 1.35 V DDR3L 1333 RDIMMs add when the chassis runs all day?

Each module draws 1.35 V at standard DDR3L current, producing modest heat that the B440 M2's existing airflow handles without extra cooling.
