Can xmp be left on all the time?

For XMP files, they are created by the manufacturer. They are the frequency and timing that can run stably for a long time after testing by the manufacturer, and have no impact on the life span

It has no impact on the life of the motherboard. The memory voltage of the motherboard is adjustable during design to support different parameters. The full name is Extreme Memory Profile. The English translation can be understood as a technology that facilitates memory overclocking. It is a technology launched by Intel in 2007. Currently, the XMP2.0 version is widely used in DDR4 memory, which is formulated and responsible for certification by Intel. .

The principle is very simple. Each XMP certified memory will have a specific area to save the overclocking data of the memory. Generally, there are XMP1 and XMP2, which can be understood as the default configuration file of the memory.

Analysis of the role of computer memory XMP mode:

The main function of memory XMP is to overclock the memory frequency, but XMP is overclocking within the range set by the manufacturer. A safe overclocking, XMP is equivalent to writing two sets of working configuration files to the memory. Turning on the XMP mode in the BIOS allows the motherboard to read the memory configuration files.

For example, if the nominal frequency of the memory is 3000MHz, then the XMP mode can allow the memory to run at a frequency of 3000MHz, thereby giving full play to the performance the memory should have. The effect of XMP is basically the same as that of manual overclocking, so it can be regarded as an automatic overclocking technology for memory, which is very suitable for beginners' fool-like memory overclocking.

Is it necessary to enable XMP for computer memory?

Whether the XMP function is turned on for general memory is generally determined by the memory frequency. To be precise, as long as the memory frequency exceeds the frequency supported by the CPU's memory controller, the XMP function needs to be turned on.

In order to unify the overclocking value standard in the industry and prevent each memory manufacturer from arbitrarily setting a higher memory frequency value and writing it to the SPD, Intel proposed the XMP certification standard.

XMP-certified memory will record the speed settings of the memory in memory addresses 176 ~ 254, and can save up to 2 sets of setting values. If manufacturers need to obtain XMP certification, they must submit the memory and the settings to Intel for testing, and certification will be given after passing the test.

So XMP overclocked memory does not damage the memory or the motherboard. However, the temperature of the memory is higher in the overclocked state. It is best not to continue to use it.

If the CPU supports, for example, 6-division frequency, it will not change after enabling XMP. The CPU FSB can overclock the memory to 1600 or above; if the CPU does not support it, after turning on XMP, the CPU FSB will be automatically increased by the motherboard.
