  • 32GB capacity extends server memory headroom
  • DDR3L 1600 speed matches Cisco UCS specifications
  • ECC load-reduced design improves data integrity
  • 35V operation reduces power draw
  • Compatible with Cisco UCS B200 M3, B22 M3, B420 M3, C22 M3, C220 M3

Server memory upgrade

This 32 GB DDR3L module is built for Cisco UCS B200 M3, B22 M3, B420 M3, C22 M3 and C220 M3 servers. It delivers ECC load-reduced operation at 1.35 V for enterprise workloads. The single DIMM installs in a 240-pin slot to expand system memory capacity.

Load-reduced ECC requirement

The module uses 4Rx4 load-reduced ECC technology that cannot be mixed with unbuffered or standard registered DIMMs. Systems must support DDR3L 1600 PC3L-12800 CL11 at 1.35 V for correct operation. Buyers needing unbuffered or standard registered memory cannot use this part.

No bundled accessories

The package contains only the memory module itself. No cables, brackets, software licences or installation tools are included. Cisco part numbers UCSML1X324RYA and UCS-ML-1X324RZ-A are referenced for cross-compatibility.

Questions about this item

How does the 32GB capacity and 1600 speed translate in a Cisco UCS server?

The module delivers 32GB of DDR3L 1600 memory per slot, letting supported Cisco UCS platforms reach higher total capacities without dropping to lower speeds.

What does the DDR3L PC3L-12800 interface limit in practice?

The DDR3L PC3L-12800 interface caps data rate at 1600 MT/s and voltage at 1.35V, so the module cannot run faster or at higher voltage even if the platform allows it.

Will the 240-pin LRDIMM fit in a Cisco UCS B200 M3 or C220 M3 chassis?

Yes, the 240-pin load-reduced DIMM is designed for the DDR3L slots in Cisco UCS B200 M3, B22 M3, B420 M3, C22 M3 and C220 M3 servers.
