BIOS 0056: Graphic display error

New Contributor III


I just updated my NUC8i5BEH from 0051 to 0056 (updated from 0048 to 0051 just some days ago).


I did the update manually using the .bio-File from Intel.

After the update, only white noise was displayed on my screen (it looked like the TV pictures after the end of broadcasting a few decades ago). Unfortunately I didn't take a picture, but it looked pretty much like this one ... ( Link).

This picture occurred both when connected via HDMI and when connected via DP.

I then set the BIOS to its default values (via the Power Button menu).


After that the picture was ok. Next I adjusted my settings bit by bit back to the way I had them before the update.

As soon as I set the IGP Aperture Size to 2048 MB in the BIOS, the image is disturbed again. Up to 1024 MB everything is fine.

I'm now thinking about reinstalling the old BIOS 0051. Is this recommendable?


Is it possible to just flash the from a higher version?

EDIT: Maybe I should add that the picture is disrupted right after turning on the NUC, so I guess its nothing with the Screen Resulution.

I downgraded to 0051 ... and graphics are OK with 2048 MB IGP Memory.


Whatever Intel did ...

Hello Trial-Member

My advise is to leave default video memory settings in bios as is. Those settings are used only by bios during boot process and before O.S. takes over (to display logo, boot menu, UEFI bios ...) and they don't have affect how much video memory is used by Windows. If you will increase those value, it will only reserve more RAM for bios and leave less memory for your needs.

In this system (with Intel Integrated Graphics and Windows 10), the amount of video memory is assigned automatically by Windows 10. Maximum it is half of your RAM memory.

More detailed explanation you can read under this link: Frequently Asked Questions for Intel® Graphics Memory on Windows® 10

You can see how much Total Available Graphics Memory you have in your system. To do this open the Advanced Display Setting and then the Display adapter properties.

Hope this helps
