32GB DDR3L ECC Registered RDIMM

This 32GB DDR3L 1600 module is an ECC registered RDIMM built for Dell PowerEdge R520, R620, R715, R720 and R720xd servers. It operates at 1.35V with CL11 latency and a 4Rx4 rank structure. The part is intended for workstation and server platforms that require registered ECC memory. It will not work in standard desktop computers or systems that only accept unbuffered modules.

Installation notes

The 240-pin DIMM installs like any server memory module: align the notch, press until the retention clips lock, then verify the new capacity in BIOS. Because the module is registered and ECC, it cannot be mixed with unbuffered or non-ECC memory on the same channel; doing so will prevent the system from posting. Ensure all populated slots use identical registered ECC specifications.

Compatibility check

Confirm that your server model is one of the listed PowerEdge systems and that the memory slots support DDR3L 1600 registered ECC RDIMMs. Verify the maximum supported capacity per slot and the total population limit for your specific CPU configuration. Check whether the existing modules are also 1.35V registered ECC; mixing voltages or registered and unbuffered types is not supported. Buyers who need unbuffered memory or a different voltage should not order this module.

Questions about this item

How can I confirm the 32GB DDR3L 1600 module is running at PC3L-12800 CL11 with ECC registered after installation?

Enter the server BIOS or use a hardware utility such as CPU-Z or dmidecode; verify the module reports 1600 MHz, CL11 timings, 1.35 V, ECC enabled and registered operation.

What ships with the OWC 32GB DDR3L 1600 ECC RDIMM and what must I source separately?

The box contains a single 32GB 240-pin DDR3L 1600 PC3L-12800 CL11 4Rx4 1.35V ECC registered RDIMM; no cables, brackets or additional DIMMs are included.

Which capacity and rank should I choose for a Dell PowerEdge R720 that needs a 32GB registered ECC upgrade?

Select the 32GB 4Rx4 DDR3L 1600 PC3L-12800 CL11 1.35V registered RDIMM — it matches the R720 spec and cannot be mixed with unbuffered memory.
