Microsoft Windows 11

I have a system with 16GB of RAM installed (2x8GB). After updating to the F20 BIOS and installing some recent updates, one of my RAM slots stopped working properly.

Now, the system only works when I use a single RAM stick. If I install both modules, the computer frequently crashes with blue screen errors. I’ve tested each RAM stick individually, and they both work fine when used alone. However, when both are installed, the system becomes unstable.

I also tested each slot separately, and it seems that one of the slots is no longer functional. The second slot doesn’t work at all.

This issue started only after the BIOS update. Could you please advise how to resolve this? Is this a known issue with the F20 BIOS version?

@cua33, Welcome to HP Support Community,

 

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

 

It sounds like you're dealing with an issue that may be related to the F20 BIOS update, which could have impacted your system’s RAM configuration or how it handles memory slots. Since this issue began after the BIOS update, the first thing to check is whether the update itself may have caused compatibility problems with your RAM or motherboard.

 

Revert to an Older BIOS Version

Since the issue started after updating to BIOS version F20, reverting to a previous BIOS version might help resolve the problem. 

I suggest you refer to this guide to recover the BIOS: HP Notebook PCs - Recovering the BIOS (Basic Input Output System) | HP® Support

 

Reset BIOS to Default Settings

Reboot your computer and enter the BIOS setup (usually by pressing F10 or ESC during startup).

Look for the option to reset to default settings.

Save the changes and exit the BIOS.

After doing this, check if the RAM issue persists.

 

Run Memory Diagnostics

Press Windows + R and type mdsched.exe.

Choose “Restart now and check for problems”.

After the restart, the memory diagnostic tool will run.

 

I hope this helps.

Please feel free to reply here if you have any questions or if you need further clarification on any of the steps. 

 

Take care and have a good day.
