The question concerns RAM speed and seems unclear. Could you provide more details?

The issue you mentioned is a blank space at the end of the bus. If all details are filled in, there shouldn't be any... Attainable speeds might decrease slightly due to other factors like CPU, board, and sticks, but it won't reach zero completely.
DDR4 is realistically limited to around 3800 to 4000 MHz for Ryzen, while similar issues might appear on Intel boards. The main problem lies in the CPU memory controller side.
I'm not sure if Gigabyte's claims are accurate regarding the memory OC capabilities. It seems unlikely many CPUs can handle that performance with 4 dual-rank (32GB) modules. AMD's official specs for Zen 3 indicate: double the single-rank speed, quadruple it, and triple it with four dual-rank sticks. Zen 4 improves from 5200 with two single-rank sticks to 3600 with four dual-rank sticks using DDR5.
