Then check the reported memory frequency. The menu name and path vary by motherboard, and the profile is not guaranteed to work at its rated speed or remain stable on every CPU-and-board combination.
What XMP and DOCP do
XMP means Intel Extreme Memory Profile. It is a stored set of memory settings—typically speed, timings, and voltage—that you can load in firmware instead of configuring those values individually. Intel describes XMP as a way to load predefined profiles for compatible memory through BIOS or a supported tuning application. Intel also classifies applying an XMP profile as memory overclocking, not as a guaranteed default operating condition. Intel’s XMP configuration guidance explains the feature and points users to their motherboard maker or PC manufacturer for system-specific instructions.

DOCP is an ASUS BIOS label for a memory profile control; other manufacturers use names such as MSI’s A-XMP. The label and location depend on the board and firmware, so do not assume every system has a setting literally named XMP or DOCP. ASUS documents its XMP and DOCP controls in its memory-profile instructions, while MSI illustrates its own A-XMP workflow in a motherboard support guide.

How to turn on XMP or DOCP in BIOS
- Find the instructions for your exact system. Identify the motherboard model (or the PC model if it is a prebuilt), then consult its manual or support page for the firmware menu and profile name. BIOS layouts and available options vary.
- Restart and open BIOS/UEFI setup. Use the setup key shown during startup or in the system maker’s instructions. If you are unsure of the key, check the manual for your exact motherboard or PC.
- Locate the memory profile control. Look for XMP, DOCP, A-XMP, or the equivalent named in your board’s documentation. Select an available profile; MSI’s example uses XMP Profile 1, but that is not a universal menu path or required choice.
- Save the change and restart. Follow the firmware’s save-and-exit prompt. MSI’s example saves with F10; use the key or menu specified by your firmware.
- Check that the profile took effect. Re-enter BIOS and inspect the reported DRAM frequency, or use an operating-system view such as Windows Task Manager’s Performance > Memory page. MSI documents both checks; the display and labels can differ by firmware and Windows version.
Why is my RAM running below its rated speed?
Memory commonly starts with conservative settings. If no profile has been applied, the system may therefore report a lower frequency than the kit’s advertised profile setting. The profile can only be used if the memory modules, motherboard, processor, firmware, and installed configuration support it. MSI notes that the CPU and motherboard affect achievable overclocked frequency, and its manual says A-XMP availability depends on support from the processor, memory, and board.
#1 Best Overall
- Disclaimer: Maximum Speed requires overclocking/PC BIOS adjustments. Maximum speed and performance depend on system components, including motherboard and CPU
- Hand-sorted memory chips ensure high performance with generous overclocking headroom
- VENGEANCE LPX is optimized for wide compatibility with the latest Intel and AMD DDR4 motherboards
- A low-profile height of just 34mm ensures that VENGEANCE LPX even fits in most small-form-factor builds
- A solid aluminum heatspreader efficiently dissipates heat from each module so that they consistently run at high clock speeds
- No profile appears: Check whether the installed kit has an XMP or compatible stored profile, and confirm that the motherboard supports the feature. Consult the exact board or PC documentation and memory compatibility information.
- The system does not accept the setting or starts with defaults: Return to firmware defaults if needed, then troubleshoot using the exact CPU, motherboard, BIOS version, memory kit, and installed module configuration. There is no single recovery sequence supported for every system.
- The reported value looks different from the advertised number: Confirm what the BIOS or operating system is displaying and compare it with the kit’s profile information. Firmware and operating-system views may label or report frequency differently; consult the system and memory documentation rather than assuming a menu value is a performance guarantee.
If the installed RAM and platform already support a usable profile, you do not need to buy new memory just to try enabling it. If replacement is genuinely needed, compare a specific DDR4 kit’s profile settings with the CPU and motherboard’s supported memory configurations and compatibility documentation; no particular kit is a universal fit.

Loading the profile applies its preset speed, timings, and voltage, but the resulting frequency and stability depend on the complete platform. A successful save does not by itself prove that the advertised setting is active, so verify the frequency after restart and watch for boot or stability problems. Intel describes XMP as enhancing gaming features, but that vendor description is not a measured or guaranteed performance gain for an individual PC.
