Overclocking Profiles – DIY in 5 Ep 180

Опубликовано 11 сентября 2022, 13:00

Memory overclocking profiles can help you get the top speeds out of your computer’s memory in just a few clicks. Computer memory for PCs comes in two standard flavors. Memory built to industry standard specification, aka JEDEC spec, and memory that’s performance-tuned to exceed standard speeds, timings, and voltage, aka overclocking.

Most commonly overclocking is achieved through overclock profiles. XMP (Extreme Memory Profiles) are Intel specifications which allow you to overclock DDR3, DDR4, and DDR5 RAM to get the best performance possible out of a PC with a compatible Intel processor. This is a great option for gamers, creators, multi-taskers, or simply enthusiasts that enjoy pushing their system’s capabilities within a stable environment. XMP does not require knowledge of complex overclocking mechanics in order to take advantage of higher memory speeds and lower latencies. All that is required is memory with XMP profiles, an XMP compatible motherboard, and a CPU that will support memory overclocking. These are all easy to find, thanks to the widespread adoption of XMP in the industry.

Intel XMP
You can access XMP profiles within the BIOS on supported motherboards. They provide varying levels of overclocking depending on your system’s hardware.

An example: enter the BIOS via your PC or motherboard’s instruction manual. This requires a keyboard input during a specific part of the bootup process, though the exact input varies from system to system. It might be F10, F12, Del, or something else. You can also enter BIOS through Windows’ advanced Start menu recovery settings if the bootup window is too brief for you. Once in your BIOS, navigate to XMP settings. This menu will vary in location depending on your motherboard. It could be on your main settings screen or in an advanced settings screen pertaining to your RAM or overclocking.

To activate XMP, select your profile, save, and reboot. It’s that simple. Memory and motherboard manufacturers have already tested the speed, timings, and voltage to ensure that the XMP profiles will run in a stable way. You should still be sure to check your specific motherboard model’s qualified vendor list (QVL) or the Intel website to ensure you pick a supported part or kit for your PC. Here is a good example of a QVL: rog.asus.com/motherboards/rog-...

Generally profile 1 is the advertised speed for DDR3 and DDR4. Profile 2 may be a backup, less aggressive speed in case profile 1 turns out to be unstable. These settings have all been tested, but since hardware configurations can vary you should be aware. To turn off or adjust XMP, simply repeat this process.

XMP 3.0 is the new specification from Intel for DDR5. XMP 3.0 has three different preset profiles and two user-customizable profiles that can be set in the BIOS and saved to memory. XMP 3.0 also works with Intel’s Dynamic Memory Boost Technology on 12th gen and newer CPUs. When enabled, it will dynamically overclock the memory in real-time, providing performance where and when you need it.

XMP for AMD
For AMD system users, there is good news. Most AM4 motherboards offer full compatibility with memory featuring XMP profiles. Some manufacturers will also optimize the speed and timings of an XMP profile to run on their AM4 boards. For example, ASUS has DOCP, Gigabyte has EOCP, and MSI has A-XMP.

For AM5 motherboards, AMD introduced a whole new overclock spec called EXPO, which is an acronym that stands for AMD Extended Profiles for Overclocking. Similar to Intel XMP 3.0, EXPO supports multiple factory-tuned DDR5 profiles, plus a user customizable profile.
