Integrated GPU unknown VBIOS Version (GPU-Z)

[Akupc]

Hello, I have a problem with VBIOS of my integrated gpu on my ProBook 640 G1. Program GPU-Z shows "Unknown" next to "BIOS Version". I dont know what to do now. I tried to fix this error by different ways.. alreadu tried reinstalling the gpu driver and flashing older BIOS version of laptop, but nothing helped. In BIOS also when I change option "Video Memory Size" from 128MB to 512MB nothing happens. The graphics card is still only 128MB. So i think i have this problem because the gpu has Unknown VBIOS. So what to do now? Thanks

(i will also add photos here)

It probably it is too old now. BIOS version on Graphics card is for the version of the video card, not for machine. CPU-Z does not know which BIOS version for iGPU because iGPU in this case comes with CPU anyway. Looks like you are trying to change VRAM.

Integrated video (iGPU) does not have room for keeping VRAM, it relies on System. System will work this out and allocate/assign spare/available system RAM to VRAM automatically when required up to max limit. System will also take VRAM back when required (the number is dynamic, not fix). During the good old days, we could do this from BIOS but now OS is smarter.

The following document shows Max shared RAM for Intel iGPU versions (I can't find a similar list from AMD).

Note: Recently people post Youtube on internet saying they can change using Regedit. Many people try but the results are unpredictable.
