Ideapad 310S not showing correct Vram

Hello,

I have a Lenovo Ideapad 310s 14-ast laptop that has an AMD A9-9410 APU with a radeon R5(integrated) and radeon R5 m430(Dedicated/discrete), the last one is supposed to have 2GB of VRAM; however, in the system only appears having 512MB , in Radeon Radeon settings appears 2GB of memory, though, but it does not work with that amount of memory.

Some pictures are attached to this post for you to see them.

I have reinstalled the drivers, uninstalled them with the DDU tool in safe mode, but nothing seem to work.

I hope you can solve my problem.

I will be looking forward to you reply.

Best regards.
