Server memory kit

This 32 GB kit contains two 16 GB DDR3L registered DIMMs rated at 1600 MHz with CL11 latency. It is built for Dell PowerEdge R815, R820, T320, T420 and T620 systems that require ECC registered memory. Standard desktop boards cannot use these modules.

Low-voltage operation

Each module runs at 1.35 V, reducing power draw and heat output compared with standard DDR3. The registered buffer lightens the electrical load on the memory controller, helping stability in multi-DIMM configurations. No heat spreader is fitted, so airflow across the sticks is the only cooling required.

240-pin RDIMM form factor

The 2Rx4 organisation and 240-pin layout match the factory Dell part numbers A6761613, A6994465, A7515505, A8255125 and SNP20D6FC/16G. Mixing with unbuffered DIMMs is not supported. Buyers needing consumer DDR3 or higher-capacity registered kits must look elsewhere.

Questions about this item

How do I install the 240-pin DDR3L RDIMMs in my PowerEdge T620, and what step is often missed?

Power down the server, open the chassis, align each 240-pin module with the DIMM slot key, press firmly until both ejector clips lock, then verify in BIOS that all 32GB are recognised at 1600 MHz.

What maintenance or replacement will the 2Rx4 ECC registered modules need over time?

No routine maintenance is required; if a module fails the ECC correction logs will flag it, at which point you replace the faulty 16 GB stick with an identical DDR3L 1600 CL11 1.35 V registered DIMM.

What limit appears first when the kit runs sustained workloads in a PowerEdge R820?

The DDR3L 1600 CL11 1.35 V specification caps sustained throughput at the PC3L-12800 data rate, so memory bandwidth becomes the bottleneck before temperature or voltage limits are reached.
