I installed a videocard PowerColor Red Dragon AMD Radeon RX 550 OC, 4GB, GDDR5 - AXRX 550 4GBD5-DHA/OC in my PC, but when I type this command to get its setups in linux: lspci -v -s 01:00.0, I get the wrong values of memory, that it should be 4GB, but instead it, I get 256MB. Could we help me? I use Ubuntu 18.04. The output of the command as root  is below:
