Problem in enabling SmartAccess Memory and periodic freezing Rx 6700 XT

[yanaby]

Hello everyone,

First of all, sorry if something is not well written, I don't speak English.

I have a problem when trying to enable a function called SmartAccess Memory (SAM) on my RX 6700 XT GPU. To do this, I need to disable CMS in the BIOS and enable "Resizable BAR". However, when I disable CMS, upon starting Windows, nothing works; I can't open applications or anything else, it just shows the desktop.

Additionally, I have another issue I'd like to solve: my screen freezes periodically when gaming, when I press Alt+Tab, or when I open certain things, for example, when switching tabs in the browser or simply opening the file explorer. etc

My system specifications are:

• OS: Windows 11 Pro Version 23H2
• CPU: AMD Ryzen 7 5700G 4.6GHz Turbo + Cooler CPU Cooler Master Hyper 212 White LED
• Motherboard: Asrock B450 Steel Legend AM4 DDR4 RGB
• RAM: GeiL DDR4 16GB (2x8GB) 3200MHz Orion Black CL22
• GPU: XFX Radeon RX 6700 XT BLACK 12GB GDDR6 SPEEDSTER QICK 319
• Storage: SSD 960 GB + SSD 120 GB
• Power Supply: ADATA 750W XPG PYLON 80 Plus Bronze

If you need more information, please let me know. I'm not very familiar with this.


I have tried:

• running DDU and reinstalling the newest drivers from AMD
• reinstalling Windows​

I haven't tried:

• Updating the BIOS (I don't know how to do it -.-)

Thanks for your help.

Hi !
I think it's weird you can't use anything when you remove CSM.
Did you switch it to UEFI or did you choose something else ? (I don't know your BIOS so I'm asking)

When you reinstalled Windows, was it in UEFI ? (Was the USB key hosting the Windows installer in EFI ?)
Is your drive hosting Windows formated in GPT ? (It's better but off topic)

To update your BIOS, you can read what Asrock wrote here (it's not complicated, follow the steps, take photos with your smartphone if needed)

I never heard about being unable to use Windows when disabling CSM so it's weird to me, it could help to update the BIOS I guess.

By the way, know that Resizable BAR is something that CAN grant you like 7% more FPS or be bad on some games, I mean, it's not a magic thing. nVidia got the drivers disabling it by default for games where the performance are worse with it but AMD doesn't have this feature.

EDIT : Also, prefer THIS : https://www.amd.com/en/resources/support-articles/faqs/GPU-601.html over DDU.
You may have to reinstall the last AMD chipset drivers, I guess (intel chipset here so I'm not sure).
