4GB DDR4 2400 Desktop Memory

This 4GB DDR4 2400 module is built for desktop systems that need a straightforward capacity increase. It runs at 2400 MHz with CL17 latency and standard 1.20 V operation. The unbuffered 288-pin DIMM fits common consumer motherboards and is validated for AMD and Intel platforms.

Sustained-load behaviour

At 2400 MHz the module delivers steady throughput for everyday multitasking and background workloads. The 1.20 V rating keeps power draw predictable during extended sessions. Quality-assurance testing on each stick helps maintain consistent timings without throttling when the system runs warm.

Replaces Crucial BLS kits

This stick is a direct equivalent for Crucial BLS4G4D240FSB, BLS4G4D240FSC, BLS2K4G4D240FSB, BLS2K4G4D240FSC, BLS2K4G4D240FSE, BLS4K4G4D240FSB and BLS4K4G4D240FSC part numbers. The upgrade is worth it when an existing build has empty DIMM slots or when a failed module needs a matching-speed replacement.

Questions about this item

How much power does this 1.20V DDR4 module draw when the system runs all day?

It operates at the standard DDR4 voltage of 1.20V, keeping power draw low during continuous use. The CL17 latency at 2400MHz is handled without extra voltage.

What motherboard slot is required for this 288-pin DIMM to work?

A standard DDR4 DIMM slot with 288 pins is needed. The module is unbuffered and non-ECC, so the board must support regular consumer DDR4 memory.

Will this CL17 2400MHz stick run alongside older DDR4 modules?

The motherboard will set all installed DDR4 modules to a common speed and latency. This stick is rated for 2400MHz CL17 at 1.20V, so it will follow the slowest module present.
