My VRam decreases from 512 mb to 128 mb after installing windows, I have windows 10 enterprise 64 bit, My procesor is intel hd graphics 620, and i have 8gb of ram ddr4. I searched all the internet and youtube to find a solution i tried all the stuff i could nothing worked, and my bios settings doesnt allow me to change anything that has memory usage! PLEASE HELP ME!
how can it be correct if i have 128 mb of dedicated video memory instead of 512 mb, i bought the laptop 3 years ago and it had 512 mb of dedicated video memory, i used it 3 years like that and now i reinstalled windows and has dropped to 128, how can that be corret!
You are confusing dedicated video memory (which is limited and controlled by the bios) with system video memory (which will use upto 50% of your system memory).
You have no problems. You just think you do.
Ok, then you need to contact the manufacturer of your device and or Microsoft. Intel did not make your motherboard or bios, which controls the DEDICATED video memory. That, or Microsoft is misreporting it.
Either way, this is not an Intel problem.
"no, I didn't updated my bios, i dont know what OS i had before windows instalation!"
These are two important pieces of information, especially your previous OS.
Also, you are not on the current version of W10. Update from here:
Ok, it is difficult extracting information from you. What was the reason for installing the same OS?
If you have w10 ltsc 17763, what version did you have before?
If you have 8gb now, how much did you have before?
If you have an Acer board now, what board did you have before?
And, from what I can see, your bios is far out of date.
You really need to contact Acer to get your bios updated. And, you need to answer the questions above.
