What are the differences between xmp1 and 2 modes?

XMP is the abbreviation of Extreme Memory Profile. It is a memory certification standard proposed by Intel in September 2007 and is applicable to DDR3 and DDR4. xmp2.0 is the second generation. In order to unify the overclocking value standards in the industry and prevent various memory manufacturers from setting higher memory frequency values ​​​​to write to the SPD at will, Intel proposed the XMP certification standard. XMP-certified memory will record the speed settings of the memory in memory addresses 176 to 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.

The difference between xmp1 and xmp2 is:

1. The data is different: xmp1 data is optimized, and the data inside includes certain memory default data. In addition to these In addition to the default data of the memory, other data are data optimized by the motherboard. The xmp2 data is the default, which means that these data are the default data of the memory manufacturer.

2. The performance is different: xmp1 performance score can reach more than 2900, and xmp2 can reach more than 3000. Whether it is processor performance, display performance, or memory performance, the overall score is relatively high. of.

3. The memory frequencies are different: the memory frequency of xmp1 is slightly higher, and the memory frequency of xmp2 is slightly lower. If there is an oc next to it, you can overclock in this case, but you need to overclock yourself before performing the operation. During the process, be sure to check the stable frequency. If it is an automatic overvoltage, it will become particularly high.
