Eight green DDR3L LRDIMM modules in anti-static packaging

OWC

OWC 256GB (8x32GB) DDR3L 1600 PC3L-12800 CL11 4Rx4 240-pin 1.35V ECC Load Reduced LRDIMM Memory Upgrade Kit

SKU CH-Q2H3-WE3V1

Eight 32 GB DDR3L 1600 ECC load-reduced DIMMs totalling 256 GB for Cisco UCS B260 M4 and B460 M4 servers

  • Capacity256GB (8 x 32GB)
  • Type240-Pin DDR3L ECC LRDIMM
  • SpeedDDR3L 1600 (PC3L 12800)
  • CAS LatencyCL11
  • Voltage1.35V
  • ECCYes

Capacity 256GB (8 x 32GB)

  • Massive 256 GB capacity from eight 32 GB modules
  • Load-reduced ECC design cuts electrical load for dense server configs
  • DDR3L 1600 speed at CL11 keeps latency low
  • Low 1.35 V DDR3L voltage reduces power draw and heat
  • Validated for Cisco UCS B260 M4 and B460 M4 E7 v2/v3 platforms

Server memory upgrade kit

This kit provides 256GB of DDR3L memory across eight 32GB modules for Cisco UCS B260 M4 and B460 M4 servers. It targets administrators who need to maximise capacity in supported E7 v2 and v3 platforms. The load-reduced ECC design helps maintain signal integrity at high densities. Systems requiring unbuffered or standard registered DIMMs cannot use this kit.

240-pin LRDIMM form factor

Each module uses a 240-pin DDR3L interface operating at 1.35V with CL11 latency and a 4Rx4 organisation. The load-reduced architecture reduces electrical load on the memory bus for stable operation in fully populated slots. No heat spreader is fitted so airflow in dense blade chassis remains unobstructed. Mixing with unbuffered or registered ECC memory is not supported.

Replaces Cisco part numbers

The kit replaces Cisco UCSML1X324RYA, UCS-ML-1X324RZ-A and UCSML2X324RYE modules for direct compatibility. OWC tests every DIMM in-house and backs the upgrade with a limited lifetime warranty and free technical support. An advanced replacement programme is available to minimise downtime during a claim.

Questions about this item

What DDR3L speed and PC3L rating does this 256GB kit run at?

The eight 32GB modules operate at DDR3L 1600 with a PC3L-12800 data rate.

Which physical slot and pin count do these LRDIMMs require?

Each module uses a 240-pin DIMM slot; the kit includes eight such modules for compatible Cisco UCS B260 M4 and B460 M4 servers.

How do I install the eight 32GB LRDIMMs, and what common mistake should I avoid?

Populate all eight slots with identical 32GB LRDIMMs; do not mix them with unbuffered or standard registered ECC DIMMs.
