Server-specific ECC RDIMM

This 8 GB DDR3L module runs at 1600 MT/s with CL11 latency and 1.35 V operation. It is a registered DIMM with ECC and a 1Rx4 organisation, built for Dell PowerEdge R815, R820, T320, T420 and T620 systems. The 240-pin form factor prevents installation in standard desktop boards.

Sustained reliability under load

Registered buffering and on-die ECC maintain data integrity during continuous server workloads such as virtualisation, database serving or NAS duties. The low-voltage DDR3L design reduces thermal output compared with standard DDR3, helping stability in densely populated memory channels over long uptimes.

Registered ECC requirement

This module only works in platforms that explicitly support registered ECC DDR3L RDIMMs; it will not function in consumer desktops or any system requiring unbuffered memory. Buyers needing non-ECC or unregistered DIMMs must select a different product.

Questions about this item

How much heat or power does the 1.35V DDR3L module add when running continuously in a Dell PowerEdge R820?

The module operates at 1.35 volts, lower than standard DDR3, reducing power draw and heat output during sustained server workloads.

What must the system already have to accept this 240-pin ECC Registered RDIMM?

A compatible Dell PowerEdge R815, R820, T320, T420 or T620 with registered DIMM slots and a memory controller that supports ECC Registered DDR3L 1600.

Can this 1Rx4 CL11 stick share channels with existing Dell A7134886 modules in a T620?

Yes, it replaces Dell part numbers A7134886, A7545680, RKR5J and SNPRKR5JC/8G, so it matches the registered ECC specification required for mixed-channel operation.
