Server Memory Upgrade Kit

This OWC kit supplies 32GB of DDR3L ECC Registered memory in two 16GB modules. It is built for Supermicro H8DCT, H8DG6, H8DGT, H8DGU and H8QG7 motherboards. Workstations and servers that require registered DIMMs can use this upgrade to expand capacity. Standard desktop boards that only accept unbuffered memory cannot use these modules.

ECC Registered Operation

The modules run at 1.35V with a CL11 latency at 1600MHz. Error-correcting code and register buffering improve data integrity for continuous workloads. Because the kit is registered ECC, it must not be mixed with unbuffered memory in the same system. No heat spreaders are fitted, so airflow across the DIMMs should be maintained by the chassis.

Capacity and Headroom

The 32GB total (2 x 16GB) suits multi-VM hosts, database nodes or NAS appliances that need more RAM than factory configurations provide. Dual-rank 2Rx4 organisation helps density on boards with limited slots. Systems that require more than 32GB or that use a different DDR generation will need a different kit.

Questions about this item

Will the 2Rx4 registered DIMMs need any firmware updates or periodic replacement in a Supermicro H8DG6?

No firmware updates are required for the DDR3L modules; they are validated for the listed Supermicro motherboards and carry a limited lifetime warranty.

What is the first limit reached when the 16 GB DDR3L 1600 CL11 kits run continuously at full load?

The CL11 latency at 1600 MHz sets the throughput ceiling; sustained bandwidth is capped by the PC3L-12800 rating.

How much heat and power do the 1.35 V registered modules produce in a 24/7 server?

Each 16 GB module operates at 1.35 V without a heat spreader, so typical power draw stays within the DDR3L low-voltage envelope and thermals remain modest.
