RAMMap Weird Behavior with Unused Active - SOLVED: Integrated GPU drivers for AMD 7900x CPU Memory Leak

Hello,



I have VERY odd behavior with RAMMap showing a ton of unused active memory and it grows slowly over time and I figured out that a lot of it is caused by me opening my browser (Brave) it also happens with a clean install of chrome. Every time I open Brave, I see it grow by about 6 MB. You can understand how this can grow over the course of a few weeks to make it seem like memory usage is higher then it should be.

Here is a picture of RAMMap:

The only way I can get rid of it is to restart. I have also check tools like PoolMonX to see if it is a driver but nothing there. I also reinstalled Windows only a few days ago in hopes of fixing this issue. Everything else looks good but this is just bugging me to no end. I also have a ETW Heap Trace of when I launch brave and can give that if needed.

Hi,
My name is Igor, it's a pleasure for me to help others and I'll try to help you.

Likely this is weird Brave behavior.
Please run Task manager, go to Performance tab, select Memory and show screenshots right after boot and after ~20 Brave starts and closes.

Ok I clean restarted my machine and waited for steady state.

Here is before for task manager and Rammap:

You can see how unused active grew by about 80 MB. I opened and closed brave exactly 20 times.

Another thing, I cannot replicate this behavior easily on another machine I have. It is a completely separate machine but I copied over my Brave appdata folder and is will clean up after itself just fine. Also, I just installed chrome from scratch and made no changes and I am experiencing the exact same behavior.

Committed memory value is the same, so this is not memory leak. Do not worry about Unused memory value.

Ok. How come on my other system it seems to release itself after I shut down the browser. Already, it is sitting at 200 MB. I have also tried giving my system memory pressure to see if it would go down but that did not do the trick.

I did a boot in safe mode and I did not observe the same behavior so I am debugging what it could be. I am assuming some network driver or something is causing the growth.

Turns out it was a memory leak in a weird way from my integrated GPU drivers on my 7900x CPU. I uninstalled the Radeon drivers and the problem disappeared. Going to try and report it to AMD.

I uninstalled the AMD Radeon GPU Drivers using Display driver uninstaller. In your task manager picture, you have 2 GPUs appearing there, one is dedicated, one is integrated on your CPU. You have to make sure you don't have the integrated drivers installed and then you wont have the leak. I have no idea how to uninstall one of the AMD ones but not the other or for that matter, install only the dedicated GPU drivers without the integrated. I have an nvidia dedicated gpu so it was easier for me.

Just going to leave this here for anyone else who comes across this thread.

https://community.amd.com/t5/drivers-software/memory-leak-on-zen4/m-p/662281#M187642

The current solution is to simple install AMD's 23.11.1 drivers.

2. Select your product and clicking search.

3. Click on "Previous Drivers".

4. Download the correct drivers with version 23.11.1 or earlier.

PageTable and Unused has high memory usage. Check this to find what is hiding inside.

Edit: seems you found culprit an I have same problem
