I've tried using regedit to change from 128mb to at least 1024 mb and i also set it to 512mb in bios but it still remains in 128mb..Nothing seems to be working
Laptop Is Lenovo e560
core i5 6200U
8gb dddr3l ram
First, stop messing around with regedit. Dedicated video memory is a function of the bios and motherboard.
What is important is how much SYSTEM memory can be allocated. For your HD 520, up to 50% of your total system memory will be automatically allocated to graphics.
I actually checked the link before trying to increase it from regedit. I also set it to 512mb in my bios setup but it's not taking effect in windows. If up .to 50% Of my ram can be allocated to graphics then i should have about 4gb of graphics since i have 8gb of ram. But like i said earlier, only 128mb is available for graphics.
Do you know how i can fix the change of the dedicated graphics in bios not taking effect in windows?
Dedicated memory is controlled by the motherboard/bios.
System memory is controlled by your HD 520.
If you want to talk about dedicated, I suggest you ask lenovo and/or microsoft.
