OWC 64GB (4x16GB) DDR3L 1333 ECC Registered RDIMM memory upgrade

SKU CH-M221-HDSVG

Adds 64 GB of DDR3L 1333 ECC registered memory to a Cisco UCS B440 M2 server

  • Capacity64GB (4 x 16GB)
  • Type240-Pin DDR3L ECC RDIMM
  • SpeedDDR3L 1333 (PC3L 10600)
  • CAS LatencyCL9
  • Voltage1.35V
  • ECCYes

Capacity 64GB (4 x 16GB)

  • ECC registered design protects data integrity in servers
  • 64 GB kit (4 × 16 GB) expands Cisco UCS B440 M2 capacity
  • DDR3L 1333 CL9 at 1.35 V lowers power draw
  • 240-pin 2Rx4 registered modules match Cisco part numbers
  • JEDEC and RoHS compliant for reliable workstation and NAS use

Server memory upgrade

This kit delivers 64GB of DDR3L 1333 ECC registered memory in four 16GB modules built for the Cisco UCS B440 M2. The 2Rx4 organisation and 1.35V operation match the platform requirements for reliable server workloads.

Replaces Cisco modules

The kit substitutes Cisco part numbers A02M316GB1L, UCSMR1X162RXA, UCSMR2X162RX and UCSMR2x162RXC. The upgrade is worth it when the blade needs maximum registered ECC capacity without mixing unbuffered or load-reduced DIMMs.

Capacity and headroom

Four slots filled with 16GB RDIMMs provide the full 64GB the B440 M2 can address in this configuration. Headroom ends at the board's four-slot limit and the DDR3L 1333 speed ceiling, so larger datasets must move to a newer platform.

Points forts

Questions sur cet article

Will the 240-pin DDR3L RDIMMs fit the Cisco UCS B440 M2 memory slots?

Yes, the kit is built specifically for the Cisco UCS B440 M2 and uses the 240-pin DDR3L RDIMM form factor required by that server.

What is the correct way to populate the four 16 GB modules, and what mistake should I avoid?

Install all four modules in the proper channel order for the B440 M2; do not mix these registered DIMMs with unbuffered or load-reduced memory.

When should I expect to replace the ECC registered memory in a production server?

These modules are rated for continuous server duty and carry a limited lifetime warranty; replacement is only needed if a module fails diagnostics.
