Hi All. Maybe someone here can help me understand.

Win10 20H2 Pro
i5 4570, 8gb-Ram, MSI H81m-P33 mobo

NO GPU card - using Intel HD Graphics

In my BIOS I can set my:
* 'Integrated Graphics Share Memory' to 1024M (This 'deducts' 1GB from my general available Ram)
* 'DVMT Memory' to Max

From what I have found online, most say that these settings makes no difference, as the onboard graphics will use the Ram that it needs anyway, up to a limit.

My question: Why then even have these settings available?

Yes, what you set in BIOS is just high limit for IGPU to use. Such IGPUs can't use any more memory anyway.

Finhobbyist said:

Hi. So will setting these high limits make any difference during IGPU intensive tasks?

Nope, only thing that might make a difference is if such memory would be set very low if you have to save on RAM. If let's say a program needs only 256MB of RAM for video purposes then it will use that much even if set to 1GB and rest of RAM would probably be lost to other uses as "Hardware reserved".

Finhobbyist said:

So its best to just leave the settings at BIOS-default, and Intel HD/Windows will use what it needs?
Any high settings is just lost Ram as "Hardware reserved"?

Exactly.

CPU-Z update: CPU-Z | Softwares | CPUID
VERSION 1.97 FOR WINDOWS®

• Intel Core i9 12900K, Core i7 12700K and Core i5 12600K "Alder Lake" CPUs and Intel Z6xx platform.
• DDR5 memory SPD and XMP 3.0 support.
• AMD Radeon 6600XT GPU.

So apparently this is a thing to watch out for now, even with trusty old Samsung SSD's
