16GB DDR4 2133MHz UDIMM Module

This A-Tech module delivers 16GB of DDR4 memory at 2133MHz. It uses the standard 288-pin UDIMM form factor and runs at 1.2V. The kit is a single unbuffered, non-ECC stick built for desktop systems.

Best For Standard Desktop Upgrades

This suits owners of DDR4 desktops needing a single 16GB stick at stock JEDEC speed. It is not for laptops, servers needing ECC, or boards limited to lower densities per slot. Check your manual for rank and voltage support before buying.

Dual Rank x8 Organisation at CL15

The module uses a 2Rx8 dual-rank layout with CL15 latency. Dual-rank density can improve throughput on compatible controllers but may not work on boards limited to single-rank DIMMs. Verify your platform accepts dual-rank modules.

Questions about this item

Does the 16GB DDR4 2133MHz module arrive as a single stick or do I need to buy a second one for dual-channel?

The package contains one 16GB UDIMM; add a second identical module if your board supports dual-channel.

Should I choose this CL15 2133MHz kit or look for a higher-speed DDR4 module?

Pick this CL15 2133MHz stick when your motherboard or CPU officially lists DDR4-2133 as the maximum supported speed.

Will the rated 2133MHz speed actually run at 2133MHz once installed in my desktop?

The module defaults to JEDEC 2133MHz at 1.2V; it will run at that speed unless the BIOS downclocks it to match the platform limit.
