Installation and Setup
Before beginning installation, ensure your computer is powered off and unplugged from the wall outlet. It is recommended to wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage to components.
Physical Installation
- Prepare Your System: Open your computer case to access the motherboard. Locate the DDR5 memory slots. Consult your motherboard manual for the recommended slot configuration for dual-channel memory.
- Remove Existing Modules (if applicable): If you are replacing existing memory, gently push down on the retention clips at both ends of the memory slot. The module will pop up, allowing you to remove it.
- Install New Memory Modules: Align the notch on the Crucial Pro DDR5 RAM module with the key in the memory slot. Apply firm, even pressure to both ends of the module until the retention clips snap into place. Ensure the clips are fully closed and the module is securely seated.

BIOS Configuration (XMP/EXPO)
After physical installation, you may need to enable the memory's rated speed in your system's BIOS/UEFI settings. This memory supports both Intel XMP 3.0 and AMD EXPO profiles.
- Access BIOS/UEFI: Restart your computer and repeatedly press the designated key (often Del, F2, F10, or F12) during startup to enter the BIOS/UEFI setup.
- Enable XMP/EXPO: Navigate to the memory or overclocking section. Locate the option for XMP (Intel) or EXPO (AMD) profiles. Select the profile that corresponds to the advertised speed (6400MHz) and timings (CL40) of your Crucial Pro DDR5 RAM.
- Save and Exit: Save your changes and exit the BIOS/UEFI. Your system will restart with the new memory settings applied.

Troubleshooting
If you encounter issues after installing your Crucial Pro DDR5 RAM, consider the following troubleshooting steps:
- System Not Booting/No Display:
- Ensure memory modules are fully seated in their slots and retention clips are closed.
- Verify that the modules are installed in the correct slots as per your motherboard manual.
- Try installing one module at a time to identify a potentially faulty module or slot.
- Incorrect Memory Speed/Capacity Detected:
- Access your system's BIOS/UEFI and confirm that the XMP or EXPO profile is enabled and set to the correct speed (6400MHz).
- Ensure your motherboard BIOS is up to date, as newer BIOS versions often improve memory compatibility and stability.
- System Instability/Crashes:
- Run a memory diagnostic tool (e.g., Windows Memory Diagnostic, MemTest86) to check for errors.
- Verify that your CPU and motherboard support the memory speed and configuration.
