Suits standard desktop upgrades

Builders adding memory to a typical office or home PC will find the speed and voltage a direct fit for many mainstream boards. Systems that require ECC error correction, registered modules or speeds above 2400 MT/s will need different memory.

Single-rank x8 DDR4 2400 specification

Each module is a single-rank, x8-based DIMM rated at PC4-19200. This organisation determines compatibility with the memory controller, so verify that your platform supports single-rank DDR4 2400 before purchase.

Questions about this item

Will these CL17 1.2V DDR4 2400 DIMMs run alongside older DDR4 sticks at 2133 MT/s?

Yes, the kit is rated DDR4 2400 CL17 1.2V and the spec notes speeds start at 2133 MT/s, so mixed modules will settle at the lowest common speed.

How can I confirm the kit is running at the rated 2400 MT/s CL17 after installation?

Check the memory tab in CPU-Z or the BIOS memory info screen; it should show 2400 MT/s (PC4-19200) with CAS latency 17 at 1.20 V.

What exactly ships in the CT2K4G4DFS824A box and is anything else required?

Two 4 GB unbuffered non-ECC 288-pin DIMMs; no heat spreader, cables or software are included and nothing extra is needed for a standard desktop slot.
