Server memory kit

This OWC kit supplies 64GB of DDR3L ECC registered memory across four 16GB modules. Each DIMM runs at 1600MHz with CL11 latency at 1.35V. The 240-pin RDIMMs are built for Supermicro A+ Server 2022TC, 2022TG, 4022G and 4042G systems.

Workstation and server builders

Suits administrators expanding compatible Supermicro A+ servers that require registered ECC DDR3L modules. Not for desktop PCs, laptops or consumer motherboards that accept only unbuffered non-ECC memory. Buyers needing higher speeds, different voltages or larger single-module capacities should look at other memory types.

Pre-install checks

Verify the target server model matches the listed Supermicro A+ series and that the motherboard supports DDR3L registered ECC DIMMs. Confirm all four slots can accept 2Rx4 modules and that the BIOS is current. Do not mix these registered sticks with any unbuffered memory already installed.

Questions about this item

Which server models must I already own for this 64GB DDR3L kit to work?

The kit is validated for Supermicro A+ Server 2022TC, 2022TG, 4022G and 4042G series.

Can I keep my existing unbuffered DDR3L DIMMs and add these registered modules?

No, registered ECC memory cannot be mixed with unbuffered memory; all slots must use registered modules.

How do I confirm the kit is running at 1600MHz CL11 after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report DDR3L 1600 PC3L-12800 CL11 at 1.35V with ECC registered active.
