Can't Get Smart Acess Memory to Work

Hi, I'm trying to get my SAM to work for a while I'm so close to give up but I want it to work.

I have enabled Re-size bar, above 4g and my Bios is UEFI. But still SAM is not working. 

I'm checking resources on my GPU properties I don't see "large memory range"
I'm checking AMD Radeon Software, it says "Smart Acess Memory Not Available"

any help appreciated.

my setup
GPU: RX 6800XT
CPU: AMD Ryzen 7 5800X
Motherboard: MSI B550-A PRO (MS-7C56)
Re-size Bar enabled, above 4g enabled, UEFI

Your harddisk or ssd has gpt not mbr? I mean you have to make a fresh windows installation.

Open 'Disk Management'. you should have a small partition labeled 'EFI System....'.

If you have that, then you also need to disable 'CSM' in mobo bios settings.

Ryzen 5 5600x, B550 aorus pro ac, Hyper 212 black, 2 x 16gb F4-3600c16dgtzn kit, Aorus gen4 7000s 2tb, Nitro+RX6900XT, RM850, Win.10 Pro..

I see Healthy EFI System partition on disk management yeah,

I searched everywhere but I can't find anything about disabling CSM in bios. I have an indicator on top it says CSM/EUFI, there csm is gray and uefi is highlighted.

Download GPU-Z. https://www.techpowerup.com/download/techpowerup-gpu-z/

Run it, go to advanced tab, then select PCIE Resizable Bar from the drop down tab and post a screenshot of what you see.

Here is mine.

It says "no" to "Resizeable BAR enabled in BIOS" but it is enabled. Check the photo from my bios. I don't know what is wrong

Re: Can't Get Smart Acess Memory to Work

Okay so after some more digging, I updated/m-flash my bios to latest and got gpu-z to show resizeable bar enabled. however AMD Radeon software still says SAM is not available. check the screenshot below. Also thank you all for the support I feel like I'm close to get this thing to work
