This inconsistency in length is due to the fact that the graphics card and the motherboard use different specifications and interface standards. Generally speaking, the length of the gold finger of the graphics card is designed according to the graphics card specifications and interface standards, while the length of the motherboard slot is designed according to the motherboard specifications and interface standards. Different graphics cards and motherboards may use different specifications and interface standards, so their gold fingers and slot lengths will be different.
It should be noted that the inconsistency between the golden finger and the groove does not necessarily mean incompatibility. Usually, the slots on the motherboard will be designed to be compatible with graphics cards with various interfaces. In this way, even if the gold finger length and slot length of the graphics card are not completely matched, it can still be inserted and used. Of course, in order to ensure compatibility and stability, it is very important to choose the graphics card and motherboard with appropriate specifications and interfaces.
In a word, the slot length of Goldfinger and motherboard is different, because they use different specifications and interface standards. This inconsistency does not necessarily mean incompatibility, but the key to ensure compatibility and stability is to choose the graphics card and motherboard with appropriate specifications and interfaces.
