Account Banned After Switching from NVIDIA to AMD GPU (ReBAR/SAM Enabled)
Hello,
My Battlefield account was banned immediately after I changed my GPU hardware, and I believe this is a false positive triggered by the hardware/driver transition.
Here is what happened:
I replaced my GPU from **NVIDIA GTX 1660 to AMD Radeon RX 9060** on Nov 21.
After the swap, I enabled **Above 4G Decoding** and **Re-Size BAR (SAM)** in my BIOS.
I also installed AMD Adrenalin, but I did not fully remove the previous NVIDIA drivers before launching the game.
Right after starting Battlefield, without playing any matches, my account was suddenly banned.
Because Re-Size BAR changes the VRAM address mapping and leftover NVIDIA driver components can conflict with AMD’s initialization, I suspect the anti-cheat may have interpreted these abnormal memory behaviors as unauthorized modifications.
I have **never used cheats or any prohibited software**. This appears to be a technical false positive caused by the hardware/driver transition.
I already opened a support case, but there's been no response for over 48 hours, so I’m requesting escalation here.
Can the technical team please review my detection logs around:
- driver initialization,
- SAM / Re-BAR behavior,
- memory map changes from GPU replacement?
I can provide DxDiag, MSInfo, or any logs needed.
Thank you for your assistance.
