Excuse me, what is 3A platform? Do you have 3N?

3A platform means that the cpu is AMD, the motherboard chipset is AMD's chipset, and the display chip of the graphics card is ATI (ATI company has been acquired by AMD), so it is called 3A platform because they all start with A, and 3N platform is not available, because NVIDIA does not produce CPU, but mainly produces motherboard chipset and graphics card chips. NVIDIA in brackets means that the motherboard is NVIDIA's chipset, and nforce98a refers to the chipset model. It's okay if you don't know the computer, just know how to give it to me!
