Targeted Server Upgrade

This 32GB kit contains two 16GB DDR3L 1600 registered DIMMs built for Dell PowerEdge R320, R415, R420, R420XR and R515 servers. It replaces Dell part numbers A6761613, A6994465, A7515505, A8255125 and SNP20D6FC/16G. The modules are not compatible with standard desktop computers.

Registered ECC Design

Each 240-pin module operates at 1.35V with CL11 latency and a 2Rx4 organisation. The registered buffer and ECC circuitry are required by the supported PowerEdge platforms and cannot be mixed with unbuffered memory. No heat spreader is fitted, so airflow in the server chassis handles cooling.

DDR3L 1600 Specification

The decisive specification is the DDR3L 1600 (PC3L-12800) registered ECC standard; only systems that explicitly accept this exact combination will recognise and run the kit correctly. Buyers needing a different voltage, speed, rank or unbuffered memory must select another product.

Questions about this item

What does DDR3L 1600 PC3L-12800 mean for real-world throughput?

DDR3L 1600 runs at 1600 MT/s with a peak transfer rate of PC3L-12800. The CL11 latency and 1.35 V operation are fixed by the JEDEC spec for this module.

Will these 240-pin RDIMMs fit my Dell PowerEdge R420?

Yes. The kit is validated for PowerEdge R320, R415, R420, R420XR and R515. Each stick is a 240-pin 2Rx4 registered DIMM that matches the Dell part numbers listed.

How do I install the pair without triggering a memory error?

Power down, open the chassis, and seat both 16 GB modules in matching-channel slots per the server's population rules. Registered ECC DIMMs must be installed in identical pairs; mixing with unbuffered memory will prevent boot.
