8 GB DDR4 2400 desktop memory

This Crucial CT8G4DFD824A module adds 8 GB of DDR4 memory to a desktop system. It operates at 2400 MHz with a CAS latency of 17 and runs at 1.20 V. The 288-pin unbuffered DIMM has no heat spreader.

Suits standard desktop upgrades.

This module fits non-ECC consumer motherboards that accept unbuffered DDR4 DIMMs. Buyers who need error-correcting code memory or registered modules for server or workstation platforms should look at a different part.

Deciding spec: 2400 MHz CL17 at 1.20 V

The rated speed of 2400 MHz with CL17 timing at 1.20 V determines whether this module matches the motherboard's supported memory profile. Verify that the board lists this exact speed and latency combination before purchase.

Questions about this item

What motherboard slot does the 288-pin DDR4 module fit?

The module fits a standard 288-pin DDR4 DIMM slot on a desktop motherboard.

Will the CL17 DDR4 2400 module run at its rated speed if I keep my existing DDR4 2133 memory?

The system will run all modules at the speed of the slowest installed kit, so the new CL17 module would operate at 2133 MT/s alongside older DDR4 2133 memory.

How can I confirm the memory is running at DDR4 2400 and 1.20V after installation?

Check the memory tab in CPU-Z or the BIOS memory information screen; both will report the current data rate and operating voltage.
