XMP for working memory

When installing memories into a system, there are many standardised timings/speeds at which memories operate. This standard is called JEDEC. You will therefore see DDR4 memory speeds such as DDR4-2400, DDR4-2133, DDR4-3000 or DDR4-2666. These are standardised speeds that all memory manufacturers adhere to.

Extreme Memory Profile (XMP) is used for working memory and can determine the speed at which memory operates. XMP is used today by all memory manufacturers for high-performance desktop memory. Unlike JEDEC, an XMP speed is more powerful and is usually optimally adapted to the specific requirements of the memory.

When purchasing an XMP compatible memory, it must also be paired with a CPU that supports its memory speeds and an XMP compatible motherboard. XMP usually has to be activated manually in the BIOS setting.

An XMP profile facilitates the overclocking of RAMs. RAM is a working memory in which all memory cells can be addressed directly via their memory address. Double data rate modules are the current standard, whereby data is processed faster so that memory access is more rapid.

To accelerate memory accesses, one can manually change the clock rate of the main memory. Intel's XMP is intended to optimise this process. Users can choose between different XMP profiles, whereby timing and memory clock are already preset. Intel's standard makes this work easier.

Overclocking usually makes no difference in everyday PC use. Programmes that only require a few resources manage well with preset clock speeds. For current games and programmes with high performance, many users use overclocking to get the maximum performance out of the hardware. The preset data does not damage the main memory. 
 

First, the appropriate XMP profile must be selected and activated in the BIOS or UEFI. To do this, the PC must first be shut down. With most manufacturers, the BIOS is displayed when restarting by pressing the F2 key. Otherwise, a short internet search helps to find out which key has to be pressed to get to the BIOS.

Then call up BIOS and navigate to the overclocking settings. Then save the settings. Then call up BIOS again. Then check that the settings have been accepted. The new clock rate can be displayed in the functions relating to the main memory. The settings can also be checked with third-party software.
