RAM & XMP/DOCP

Enable XMP (Extreme Memory Profile) for Intel or DOCP (Direct Overclock Profile) for AMD to unlock your RAM’s full speed potential. High-performance RAM often has a speed rating (e.g., 3200MHz), but it runs at a slower default speed when first installed.

Enabling XMP or DOCP in your BIOS allows the RAM to run at its advertised speed, which can significantly improve performance, especially in games and applications that require fast data transfers.

Update BIOS First

Before enabling XMP/DOCP, update your BIOS. If you enable XMP/DOCP first, your settings may revert after updating the BIOS.

How to enable XMP/DOCP

  1. Boot into the BIOS by pressing the BIOS key while your PC starts

    • Commonly Del or F2 , but check your motherboard manual for the correct key

  2. Locate the XMP/DOCP setting

    • AMD systems use DOCP, Intel systems use XMP
    • Usually found on the main BIOS screen or under an OC/Overclocking section
    • Select Profile 1, as it’s typically the most stable profile

  3. Save and exit the BIOS

  4. Run a stress test to verify stability (see below)

How to run a stress test

Memory profiles can sometimes be unstable and cause crashes. Run a stress test for at least 1 hour to verify stability before finalizing your setup.

  1. Download OCCT and install it

  2. Open OCCT and navigate to the Stability Test tab

  3. Select the Memory tab and click the green Start button

  4. Wait 10 seconds for the test to start (free users), then monitor for errors on the left side

  5. Let the test run for 1 hour without interruption

Important

If your computer blue screens, freezes, or OCCT reports errors, disable the XMP/DOCP profile immediately. Unstable memory settings can cause file corruption and random crashes.
