OWC

OWC 64GB (2x32GB) DDR3L 1600 PC3L-12800 CL11 4Rx4 240-pin 1.35V ECC Load Reduced LRDIMM memory upgrade

SKU CH-ZRA9-SAQ4H

A 64 GB DDR3L ECC Load-Reduced DIMM kit for Cisco UCS B200 M3, B22 M3, B420 M3, C22 M3 and C220 M3 servers

  • Capacity64GB (2 x 32GB)
  • Type240-Pin DDR3L ECC LRDIMM
  • SpeedDDR3L 1600 (PC3L 12800)
  • CAS LatencyCL11
  • Voltage1.35V
  • ECCYes

Capacity 64GB (2 x 32GB)

  • 64 GB capacity from two 32 GB modules doubles server memory headroom
  • ECC load-reduced design corrects errors and lightens electrical load for stable uptime
  • DDR3L 1600 speed at 1.35 V lowers power draw while keeping throughput high
  • Validated for Cisco UCS B200 M3, B22 M3, B420 M3, C22 M3 and C220 M3
  • JEDEC and RoHS compliant build tested in-house for long-term reliability

Server memory kit

This OWC kit supplies 64GB of DDR3L 1600 memory as two 32GB load-reduced DIMMs. Each module is a 240-pin ECC LRDIMM running at 1.35V with CL11 latency and 4Rx4 organisation. The parts are validated for Cisco UCS B200 M3, B22 M3, B420 M3, C22 M3 and C220 M3 servers.

Compatibility limits

The modules suit administrators upgrading or repairing the listed Cisco UCS platforms that require DDR3L ECC LRDIMM memory. They will not work in standard desktop computers, nor in systems that accept only unbuffered or registered ECC DIMMs. Buyers needing a different capacity, voltage, or form factor should look elsewhere.

Deciding specification

The 240-pin DDR3L ECC load-reduced DIMM format is the single attribute that determines fit. Only servers designed for this exact module type and pin count will accept the kit.

Questions about this item

Will these 32GB DDR3L LRDIMMs work alongside the 16GB ECC registered DIMMs already in my Cisco UCS B200 M3?

No — Load Reduced modules cannot be mixed with ECC registered or unbuffered memory, so all slots must use identical LRDIMMs.

How can I confirm the kit is running at DDR3L 1600 CL11 1.35V after installation?

Check the BIOS memory information or the Cisco UCS Manager inventory; it will report speed, latency and voltage for each installed DIMM.

Does the 64GB kit include a heat spreader or any installation tools?

The kit contains two 32GB 240-pin DDR3L LRDIMM modules only; no heat spreaders or tools are included.
