System-specific server memory upgrade

This kit provides 64 GB of DDR3L ECC registered memory in two 32 GB modules. It is built for the Cisco UCS B440 M2 blade server and similar workstation or server platforms that require registered DIMMs. The modules operate at 1333 MHz with CL9 latency and a 1.35 V supply.

Compatibility and platform checks

Verify that your system accepts 240-pin DDR3L registered ECC RDIMMs and supports 4Rx4 density at this speed. This memory will not work in standard desktop computers and must not be mixed with unbuffered or load-reduced modules. Confirm the motherboard or server documentation lists PC3L-10600 registered DIMMs as supported.

Build quality and daily implications

The modules ship without heat spreaders, relying on the server chassis airflow for cooling. JEDEC and RoHS compliance indicates standard manufacturing quality for long-term operation. The 240-pin form factor fits the B440 M2 memory slots directly, and the registered design helps maintain signal integrity in multi-DIMM configurations.
