Have you ever bought RAM for your computer / laptop but when you check your computer / laptop’s performance, the RAM is not running according to the written specifications?
If this problem occurs then there is nothing to worry about as it is not the fault of the RAM you purchased. This can happen because the motherboard being used is automatically running RAM at the standard speed approved by the JEDEC (Joint Electron Device Engineering Council). In order for the RAM you are using to work in the RAM as stated on the specification sticker, all you need to do is enter the motherboard BIOS and then enable the XMP (eXterme Memory Profile) setting.
XMP allows users to select factory settings set by their motherboard and then adjust them to the speed indicated in the RAM in use, so that the RAM can run at the speed indicated on the specification sticker.
Also note that enabling the XMP setting will void the CPU warranty, be it AMD or Intel. Why why?
Although XMP speeds up the frequency and increases the performance of the RAM, the RAM must communicate with the CPU through the CPU memory controller. So, if you are running RAM at a speed frequency that is faster than what is recommended by Intel and AMD, it is assumed that you are running the CPU beyond the specifications they provide.
For the recommended RAM speed frequencies specified by Intel and AMD, see their respective websites.
For example, the AMD Ryzen 7 3800X can run RAM speeds at a recommended frequency of up to 3200 MHz, while the Intel Core i7-10700K can run RAM speeds at a recommended frequency of up to 2933 MHz. Using RAM at the frequency recommended above will void the warranty for the brand of CPU for which you are claiming the warranty.
Now the question arises whether you should use the XMP function in the RAM in use.
The answer depends on each individual’s opinion. If you want more performance and are not too concerned with the warranty period, the XMP feature is for you, especially if you have a Ryzen CPU. However, if you don’t want to take any chances, it would be a good idea to only enable this feature once you really know how to use it and wait for the warranty period to expire.
