8gb? GPU-Z shows 4096 MB which is 4 GB. Part number in GPU-Z shows 4 GB (GV-RX580Gaming-4GD)
Part number on the memory is H5GC4H24AJR which is only used on 4 GB cards.
There is nothing strange.
then why have 8 módules of vram??, or its 8 módules of 512 vram, As additional information, I think I also have a modified BIOS.

byte != bits. One byte = 8 bits
H5GC4H24AJR is a 4Gb (gigabit) memory chip. 4Gb means 512 MB (megabytes) per memory chip.
512 MB (megabytes) * 8 modules = Total of 4096 MB (megabytes)
If you looked up the part number GV-RX580Gaming-4GD, you would have seen that your bios has the correct gpu and memory clock speeds:
GIGABYTE RX 580 GAMING 4 GB Specs
AMD Polaris 20, 1340 MHz, 2304 Cores, 144 TMUs, 32 ROPs, 4096 MB GDDR5, 1750 MHz, 256 bit
Like I said before. There is nothing strange about your card.
