Server-specific ECC upgrade

This 16GB kit contains two 8GB DDR3L 1600 CL11 registered DIMMs built for Dell PowerEdge R320 R415 R420 R420XR and R515 servers. The modules run at 1.35V and use a 1Rx4 organisation with ECC error correction. They replace Dell part numbers A7134886 A7545680 RKR5J and SNPRKR5JC/8G.

Not for desktop or unbuffered builds

Buyers upgrading standard desktop PCs or consumer laptops cannot use this memory because it requires a registered ECC platform. Systems that only accept unbuffered non-ECC DIMMs will not post with these modules installed. Mixing this kit with any unbuffered memory is also unsupported.

Registered ECC DDR3L 1600 1.35V 240-pin

The single specification that decides fit is the registered ECC DDR3L 1600 1.35V 240-pin form factor required by the listed PowerEdge models. Only servers that explicitly support this exact combination will recognise and run the kit at its rated speed.

Questions about this item

Will the 1600 MHz speed run at full rate in a Dell PowerEdge R420?

The R420 memory controller supports DDR3L 1600, so both 8 GB modules will operate at the rated 1600 MT/s with CL11 timing.

Does the 240-pin DDR3L RDIMM interface limit total capacity per channel on these servers?

Each 240-pin registered DIMM presents one 1Rx4 load; the R320, R415, R420, R420XR and R515 all accept this density per slot without reducing channel speed.

What clearance is needed above the motherboard for the 1Rx4 modules without heat spreaders?

Bare 240-pin DDR3L RDIMMs are low-profile; they fit the standard 1U and 2U Dell PowerEdge chassis without extra vertical clearance.
