16GB DDR3L 1066 ECC RDIMM

This 16GB registered DIMM uses DDR3L technology at 1066 MHz with a low 1.35V operating voltage. It is built for server and workstation platforms that require ECC error correction and a 240-pin DDR3 form factor.

Suits Dell part numbers including A5093478

Systems that accept registered ECC modules at this speed and voltage will benefit from the upgrade. Builders whose platforms require unbuffered non-ECC memory or a different pin layout cannot use this module.

Registered 4Rx4 organisation with CL7 latency

The 4Rx4 rank structure and CL7 CAS latency define how the memory controller addresses the chips. Verify that your motherboard supports registered 4Rx4 DDR3L DIMMs before purchasing.

Questions about this item

Will this 240-pin DDR3L module fit my server's memory slots?

Yes — the stick is a standard 240-pin DDR3 DIMM that installs in any DDR3L or DDR3 RDIMM slot keyed for 1.35 V operation.

What is the correct way to seat this registered ECC DIMM so the server recognises all 16 GB?

Open the retention clips, align the notch with the slot key, press straight down until both clips snap shut, then power on and verify the full 16 GB appears in BIOS.

How long can I expect this 1.35 V 4Rx4 module to run before a replacement is needed?

The module carries a lifetime warranty from the manufacturer, so under normal server workloads it should not require scheduled replacement.
