Four green 240-pin DDR3L ECC RDIMM modules in anti-static packaging

OWC

OWC 32GB (4x8GB) DDR3L 1066 PC3L-8500 CL7 4Rx8 240-pin 1.35V ECC Registered RDIMM Server RAM Kit

SKU CH-ZWS1-14WQ6

A 32 GB DDR3L 1066 ECC registered RDIMM kit for servers and workstations

  • Capacity32GB (4 x 8GB)
  • Type240-Pin DDR3L ECC RDIMM
  • SpeedDDR3L 1066 (PC3L 8500)
  • CAS LatencyCL7
  • Voltage1.35V
  • ECCYes

Capacity 32GB (4 x 8GB)

  • ECC registered design protects data integrity in servers
  • 32 GB kit with four 8 GB modules expands capacity
  • DDR3L 1066 PC3L-8500 CL7 meets JEDEC standard
  • 35 V low-voltage operation reduces power draw
  • 240-pin RDIMM form factor fits select workstations and servers

Server Memory Kit

This OWC kit supplies 32GB of DDR3L ECC registered memory in a matched set of four 8GB modules. It is built for workstations, servers, NAS systems and routers that require 240-pin DDR3L 1066 registered DIMMs with error correction.

Thermals and Power

The modules run at 1.35V without heat spreaders, relying on system airflow for cooling. Registered buffering and ECC functionality add minimal electrical load while maintaining signal integrity across the dual-channel configuration.

What the Kit Changes

JEDEC and RoHS compliance ensures a warranty-safe upgrade that meets OEM specifications. The four-module kit populates dual-channel slots for maximum bandwidth on compatible platforms. Buyers needing unbuffered memory or desktop compatibility should look elsewhere.

Questions about this item

How do I install these 240-pin DDR3L RDIMMs, and what step do people get wrong?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both latches click, then verify all four 8 GB sticks are recognised in BIOS; the common error is mixing these registered DIMMs with unbuffered memory, which prevents boot.

What maintenance or replacement will this 32 GB kit need later?

No routine maintenance is required; if a module fails, replace the faulty 8 GB RDIMM with an identical DDR3L 1066 CL7 1.35 V 4Rx8 registered part to keep ECC and rank matching.

What limit appears first under sustained load with these CL7 1.35 V modules?

The DDR3L 1066 (PC3L-8500) data rate and CL7 latency set the throughput ceiling; sustained workloads will hit that bandwidth limit before voltage or thermal constraints become an issue.
