64GB DDR4 2933 kit for Supermicro boards

This NEMIX RAM kit delivers 64GB of DDR4 memory across four 16GB unbuffered UDIMM modules rated at 2933MHz CL21 and 1.2V. It is built to the exact rank, voltage and timing the supported Supermicro X12SAE and X12SCA-F motherboards expect for full-capacity recognition. The 288-pin non-ECC design matches the desktop UDIMM form factor those boards require.

Suited for verified Supermicro upgrades.

Builders upgrading a compatible Supermicro X12SAE or X12SCA-F system can install this kit with confidence that the memory controller will recognise every module at its rated speed. Buyers who need ECC error correction, registered modules or laptop SODIMM form factors should look elsewhere, as this kit provides none of those features.

Four ranks of 16GB handle multitasking.

The four single-rank 16GB modules give 64GB total capacity, which comfortably runs typical desktop workloads, virtual machines and large datasets within the board's supported limits. Systems requiring more than 64GB or faster speeds than 2933MHz will exceed what this specific kit and the validated motherboards can provide.

Questions about this item

Do I need a Supermicro X12SAE or X12SCA-F motherboard with four free 288-pin DDR4 UDIMM slots for this 64 GB kit to work?

Yes, the kit is validated for those two Supermicro boards and requires four available 288-pin UDIMM slots to install all four 16 GB modules.

Can I keep existing DDR4 UDIMM modules installed while adding this 4×16 GB kit to the same board?

The motherboard manual defines the approved population order; mixing ranks or speeds may force the system to run at the lowest common timing.

How do I confirm the 64 GB kit is running at DDR4-2933 CL21 after installation?

Check the BIOS memory information or a system utility such as CPU-Z to verify 2933 MT/s speed, CL21 latency, 1.20 V voltage and full 64 GB capacity.
