Question Amd radeon graphics 448sp vram issue

[MagicEmperor07]

So, few days ago I changed my laptop paging file value from automatic to 512mb then I restarted windows. After that I noticed that my igpu vram is changed from 2gb to 512mb which is now causing bottle neck while playing games. In order to reset it's value I again changed paging value from 512mb to automatic but it didn't changed ipgu vram. Then i tried resintalling windows and updating laptop bios but none of them worked. then i tried updating igpu vbios but vbios for amd radeon graphics 448sp is not available online. and laptop bios is locked so far for advance change in hardware.
what should i do now? please can anyone help?

yeah mine also has a egpu but it's not causing any issues. my laptop doesn't support mux switch so it use igpu as display output and it only has 512mb vram so it's causing bottleneck for both egpu and cpu

for igpu. vram, is the system ram.
does your hp see all 8gb ram?

[i was busy so i was not able to reply till now]
i have upgraded my ram from 8gb to 16gb. and i do know that igpu doesn't have dedicated memory so it use ram as vram .
and my laptop show 15.3gb ram is useable out of 16gb.
