OWC 16GB DDR3L 1600 ECC RDIMM

This OWC module provides 16GB of DDR3L 1600 memory with ECC and registered buffering. It uses a 240-pin form factor and operates at 1.35V with CL11 latency. The 2Rx4 rank configuration is built for Dell PowerEdge servers including the R815, R820, T320, T420 and T620 models.

For servers needing registered ECC memory

This memory suits administrators upgrading or repairing the listed Dell PowerEdge systems where registered ECC DDR3L is required. It will not work in standard desktop computers or consumer motherboards that accept only unbuffered non-ECC modules. Buyers who need unbuffered memory or a different DDR generation should look elsewhere.

Registered ECC DDR3L at 1.35V

The module is registered ECC DDR3L running at 1.35V, a combination that determines whether it fits the target server's memory controller and slot keying. If the system requires unbuffered memory, a different voltage or a newer DDR generation, this part will not be compatible.

Questions about this item

What speed and bandwidth does the DDR3L 1600 interface deliver in practice?

The module runs at DDR3L 1600 (PC3L-12800) with CL11 latency, providing 12800 MB/s peak bandwidth at 1.35 V.

What physical slot and form factor does this 240-pin RDIMM require?

It fits a standard 240-pin DDR3 DIMM slot in Dell PowerEdge R815, R820, T320, T420 or T620 servers; no heat spreader is present.

How is the ECC registered module installed, and what common step is missed?

Power down the server, open the chassis, align the notch on the 240-pin edge connector, press firmly until the retention clips click, then verify in BIOS that ECC registered mode is active — mixing with unbuffered DIMMs will prevent boot.
