4GB DDR4 2400MHz Desktop DIMM

This 4GB DDR4 module runs at 2400MHz with CL17 latency and 1.20V operation. It uses a standard 288-pin unbuffered DIMM form factor and non-ECC major-brand chips. The stick is built as a direct replacement for Crucial BLS4G4D240FSE and BLS4K4G4D240FSE part numbers.

Suitable for basic DDR4 desktop upgrades

It fits owners of AMD and Intel desktop boards that accept DDR4 2400MHz UDIMMs and need a single 4GB module to fill a free slot or replace a failed stick. Builders planning dual-channel kits, higher frequencies, ECC support or larger capacities per slot should choose a different product.

Speed and latency define the fit

The tested frequency is 2400MHz (PC4-19200) with a CAS latency of 17. If the motherboard or existing memory requires a different speed grade or lower latency, this module will not match the required specification.

Questions about this item

Will this DDR4 2400 MHz CL17 module run alongside my existing DDR4 memory?

It is a standard DDR4 DIMM operating at 1.20 V with CL17 timings; the system will clock all installed modules to the lowest common speed and latency.

How can I confirm the module is running at the correct 2400 MHz speed after installation?

Check the memory frequency in your BIOS or a system information tool; it should report 2400 MT/s (PC4-19200) for this stick.

What is included in the box and do I need any extra parts to install it?

The box contains the single 4 GB 288-pin DDR4 UDIMM; no cables, brackets or additional components are required for installation.
