二. How to enable DIMM Fit in BIOS?
For example, the motherboard: TUF GAMING Z890-PLUS WIFI, and BIOS has enabled XMP, with memory frequency overclocked to 6400MHz.

(For information on how to enable XMP or other overclocking options, refer to the FAQ:  How to optimize the Memory performance by setting XMP or EXPO or DOCP in BIOS)

* Due to memory differences and compatibility, it is recommended to use memory listed in the official website's QVL. 
1. After power on, press the "Delete" key on the keyboard to enter BIOS [EZ Mode] 

2.Press the F7 key on the keyboard to enter [Advanced Mode], as shown in the image below.
