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:

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Baffin [Radeon RX 550 640SP / RX 560/560X] (rev ff) (prog-if 00 [VGA controller])
Subsystem: Tul Corporation / PowerColor Baffin [Radeon RX 560]
Flags: bus master, fast devsel, latency 0, IRQ 28
Memory at e0000000 (64-bit, prefetchable) [size=256M]
Memory at f0000000 (64-bit, prefetchable) [size=2M]
I/O ports at e000 [size=256]
Memory at f7c00000 (32-bit, non-prefetchable) [size=256K]
Expansion ROM at 000c0000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: amdgpu
Kernel modules: amdgpu

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:
