8GB DDR3L ECC Registered RDIMM

This OWC module delivers 8GB of DDR3L memory at 1600MHz with CL11 latency and 1.35V operation. It uses a 240-pin registered DIMM form factor with 1Rx4 organisation and ECC error correction. The part replaces Dell part numbers A7134886, A7545680, RKR5J and SNPRKR5JC/8G.

Workstation and server upgrades only

The memory is built for Dell Precision R7610, T3600, T3610, T5600 and T5610 systems that require registered ECC modules. It will not work in standard desktop computers or any platform that accepts only unbuffered memory. Mixing this module with unbuffered DIMMs is not supported.

Registered ECC with 1Rx4 organisation

The single decisive specification is that this is an ECC registered RDIMM with a 1Rx4 rank configuration. Your system must explicitly support registered ECC DDR3L in this organisation; unbuffered or non-ECC platforms cannot use it.

Questions about this item

How much power does the 1.35V DDR3L module draw when the workstation runs continuously?

Operating at 1.35V instead of standard 1.5V DDR3 reduces power draw and heat output during all-day workloads in Precision R7610, T3600, T3610, T5600 and T5610 systems.

What must the motherboard support for this 240-pin ECC Registered RDIMM to function?

The platform must accept DDR3L 1600 ECC Registered memory in a 240-pin slot; it will not work with unbuffered DIMMs or standard desktop boards.

Can I add this 1Rx4 module alongside existing DDR3L Registered DIMMs in a Precision T5600?

Yes, provided the other modules are also DDR3L 1600 ECC Registered; mixing with unbuffered memory is not supported.
