new graphics card vs existng system drivers

[Archtype]

Running an HP Pavillion desktop with 32g of ram.One of two of my original HP VH240a monitors died (both driven with AMD Radeon Graphics dirvers), and I've replaced it with an HP V27i FHD which loaded a Generic Window driver.

The original drivers were limited to 512mb ram using the AMD Drivers.

I tried to install a PNY 4gig PCie graphics card but the configuration of the Pavilion case is that I cannot get the card to secure in the slot due to a hinged closure to hold the card in place, which will not close and lock with the board in place.

It appears there is no AMD graphics card, Just the drivers sharing the  AMD Chip on the motherboard and a portion of the 32gb of system RAM.

Is it possible to to reconfigure the memory for the AMD drivers to the desired 4gb and get the new monitor to use the adjusted memory and the AMD Graphics drivers?.
