Enable XMP or EXPO in BIOS

Introduction

If your CLX PC includes performance memory, you may need to enable XMP or EXPO in BIOS to run the RAM at its advertised speed. This guide explains how to turn on the correct memory profile for Intel or AMD systems, confirm the change in Windows, and what to do if the system becomes unstable afterward.

Issue description

By default, many systems run memory at a standard speed instead of the rated speed printed on the RAM kit. Enabling the manufacturer profile in BIOS applies the tested memory settings so your CLX system can operate at the intended performance level.

Signs

• Windows shows a lower RAM speed than expected in Task Manager
• Your memory is running at default JEDEC settings instead of the rated profile
• You want to optimize system performance for gaming or demanding workloads
• The system becomes unstable after a memory profile change

Basic troubleshooting steps

• Confirm whether your system uses Intel or AMD hardware
• Check that your memory kit supports XMP or EXPO
• Make sure the system is fully shut down before entering BIOS
• Record your current BIOS settings before making changes

Step-by-step instructions

1. Restart your CLX PC and enter BIOS during startup. Press the BIOS key shown on screen, such as Delete or F2, as soon as the system begins to power on.

2. Locate the memory profile setting in BIOS. On Intel systems, look for XMP. On AMD systems, look for EXPO.

3. Enable the available profile. If more than one profile is listed, select the recommended profile for your memory kit.

4. Save your changes and exit BIOS. The system will reboot with the new memory settings applied.

5. Confirm the new speed in Windows Task Manager or return to BIOS to verify the memory frequency.

Tips and best practices

• Enable only the profile recommended for your RAM kit
• If the system fails to boot or becomes unstable, revert to default settings
• After enabling XMP or EXPO, test the system with normal use before making additional BIOS changes
• Keep your BIOS updated if CLX support recommends a newer version for memory compatibility

Next steps

If your CLX PC is stable after enabling XMP or EXPO, you are ready to use your memory at its rated performance. If you experience crashes, boot loops, or other instability, return to default BIOS settings and contact CLX Support for further tuning and diagnosis.

Contact support

If you need help enabling XMP or EXPO, or if your system becomes unstable after changing memory settings, contact CLX Support through your standard support channel. Be ready to share your system model, memory kit details, and any error messages or symptoms you are seeing.
