Disable Resizable Bar

[Gabarowski]

Hello!

I'd like to disable resizable bar feature, I did it in BIOS but GPU-Z still write it is enabled. I have no clue what to do, please help.

BIOS version: ACADL357.0065.2024.0409.1723

Looks like a fluke in GPU-Z

Double-check with HWiNFO

Report discrepancies at Testing please: GPU-Z Resizable BAR Support Report

What is the motivation to disable rebar?

Does any reputable tech site report issues with that?

[Gabarowski]

In HWiNFO is the same (enabled)

My motivation is that I'm having audio stutter for half a sec every 2-3 mins on both Win10 and 11, someone wrote that ReBar cause this so I wanna turn it off, I'm not a huge game, I'm more like a creator.

So basically that's the only reason I want to disable it, I'm having this very annoying audio stutter, even in DAW and Video Editor.

The root cause appears to be closely linked to the power spike that occurs when the GPU switches from lower power states (L0S/L1) to normal operational states.

@Sorrow have you solved this issue? If yes, can you write down how to please?

[Sorrow]

Sadly no. Intel has concluded that my laptop was defective. I'll have to start the RMA Process.

Although the 4575 driver shows the resizable bar correctly, there are still freezes due to changes in the power states of the dGPU

[Gabarowski]

Oh no, I have the same issue, Event Viewer writes the same to me.

Did you send your laptop already? What was the process? Which country do you send from?

[Sorrow]

Not yet, I still need my laptop to do some unfinished work. 

But I've contacted my retailer, I will send it to them as soon as I am ready

@ACarmona_Intel  The problem is solved with the 4575 version of Arc Control.

It's a shame that the newer versions of Arc Control shows the ReBar falsly.

I really hope Intel's development team will fix this in the future, I'll only update my driver whenever the updates announcement shows fix for lapac71h model. 

All the best!

Hello Gabarowski ,

Thank you so much for the update.

I agree with your plan, wherein you will only update your driver whenever the update announcement shows a fix for the Lapac71h model. 

I'm also hoping that the drivers that will be soon released by us will fix the issue that you have.
