Instalei uma Placa de Vídeo nova PowerColor Red Dragon AMD Radeon RX 550 OC, 4GB, GDDR5 - AXRX 550 4GBD5-DHA/OC
Quando digito esse comando para ver suas configurações: lspci -v -s 01:00.0

Me retorna um valor 256MB, sendo que ela é de 4GB. Alguem pode me auxiliar? Minha distro é Ubuntu 18.04.

Rode como root e veja o que aparece, mas já tem mais memória do que você achou.

Veja:

Tudo que está destacado é memória, se não me engano.

Não teria que aparecer 4GB de memória, já que esta' é a capacidade? Segue o resultado do comando em root:
