Dell-Compatible Server Memory

This A-Tech 8GB DDR3L 1600 ECC RDIMM is a registered server memory module designed as a direct replacement for Dell part numbers A7134886, A7545680 and RKR5J. It operates at 1.35V with CL11 latency and uses a 240-pin DIMM form factor with a 1Rx4 rank configuration.

Ideal for Server Upgrades

This module suits administrators upgrading compatible Dell PowerEdge servers or workstations that require registered ECC memory at DDR3L voltage. It is not suitable for systems that only accept unbuffered UDIMM modules, platforms limited to standard 1.5V DDR3, or builds needing capacities beyond a single 8GB stick.

Registered ECC with 1Rx4 Layout

The registered ECC design with a single-rank 1Rx4 organisation is the decisive specification; the motherboard memory controller must support registered DIMMs and this specific rank structure for the module to function correctly.

Questions about this item

Does my server need a 240-pin DDR3L slot to use this module?

Yes, the module is a 240-pin DDR3L DIMM running at 1.35V, so the motherboard must provide a DDR3L registered DIMM slot.

Can I mix this 1Rx4 ECC RDIMM with existing 2Rx4 modules in the same channel?

Mixing ranks is often allowed by the platform, but you should check the server manual for supported rank combinations per channel.

How do I confirm the system recognises the full 8GB at 1600MHz after installation?

Enter the BIOS or UEFI and verify the memory size shows 8GB, speed reads 1600MHz, and ECC status is reported as active.
