Server memory kit

This OWC kit supplies 64GB of DDR3L ECC registered memory in two 32GB modules. It is built for Dell PowerEdge M420, M520, M620, M820 and M915 servers that require registered DIMMs. Standard desktop systems cannot use this memory.

Sustained operation

The modules run at 1.35V and meet JEDEC PC3L-12800 specifications for continuous server workloads. ECC registration corrects single-bit errors during extended uptime, helping maintain data integrity under constant load.

Registered ECC constraint

The 4Rx4 registered design only works in platforms that support registered ECC DIMMs. Buyers needing unbuffered memory for workstations or consumer motherboards must choose a different module type.

Questions about this item

Does the 1.35 V DDR3L voltage help reduce heat in a Dell PowerEdge M620 running 24/7?

Yes, the 1.35 V DDR3L modules draw less power than standard 1.5 V DDR3, so they generate less heat during continuous operation in the M620.

What must the server already support to use these 4Rx4 registered ECC DIMMs?

The system must accept 240-pin DDR3L registered ECC RDIMMs and be able to address 4Rx4 modules at 1600 MHz.

Can I keep my existing DDR3L 1600 modules and add this 64 GB kit to a Dell PowerEdge M820?

Only if the installed memory is also registered ECC DDR3L at 1600 MHz; mixing with unbuffered or different-speed DIMMs is not supported.
