Radeon Memory Guard

Published v0.5.1 release guide

Radeon Memory Guard maintains a workaround for an identified AMD Radeon memory leak and redirects repeated executable-cache writes to a 64 MiB RAM disk. AMD External Events Utility stays running.

Experimental. May cause instability, application crashes or loss of AMD features. Driver and Windows updates may break protection. Restore saved settings or uninstall if problems appear.

Tested on Radeon RX 7900 XTX, AMD driver 32.0.32015.12012, and Windows 11 Pro 26H2, build 26300. See validation and compatibility limits.

Install

1. Download RadeonMemoryGuard-Setup-0.5.1.exe from GitHub Releases.
2. Run Setup as administrator. Complete setup enables memory maintenance and RAM redirection; Custom offers memory maintenance only.
3. Check Status after installation and after updating your Radeon driver.

Requires 64-bit Windows and an official AMD Radeon driver. Setup includes the signed Arsenal/AWEAlloc storage drivers used by RAM mode.

The installer is self-signed, so Windows may display an unknown-publisher warning. Verify its signature and SHA-256 checksum.

Operation

A hidden SYSTEM task runs at startup and every five minutes. It maintains Gmx_MgpuProcessWatcherSupport=0 for the active supported AMD display service and repairs the RAM-cache link when needed. It has no window or tray icon.

RAM mode uses 64 MiB of locked physical memory, plus filesystem and driver overhead. It redirects the SYSTEM-profile atieclxx.exe cache; ordinary AMD logs and shader caches remain on disk.

A driver update can load before maintenance applies the setting. AppliedNeedsReload means activation needs a later driver reload or Windows restart. The guard does not restart either automatically, and it cannot reclaim memory already leaked in the current session.

Status

Open Windows PowerShell as administrator:

powershell.exe -NoProfile -ExecutionPolicy Bypass -File "$env:ProgramFiles\JZB Apps\Radeon Memory Guard\RadeonMemoryGuard.ps1" -Action Status -Json

Repair or uninstall

Run Setup again to repair the installation. To remove it, choose Restore and uninstall from the Start menu or uninstall through Windows Settings.

Removal restores saved AMD settings and the original cache file, releases the RAM disk, and removes unused components installed by the guard. Shared drivers and recovery records are preserved. If restoration encounters a conflict, recovery files remain available.

Portable use

Extract the ZIP and open Windows PowerShell 5.1 as administrator in that folder:

powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\RadeonMemoryGuard.ps1" -Action Install
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\RadeonMemoryGuard.ps1" -Action InstallRamBackend
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\RadeonMemoryGuard.ps1" -Action ProtectSsdRam
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\RadeonMemoryGuard.ps1" -Action Status -Json

Use -Action RestoreSsd to restore the cache and service settings, or -Action Uninstall to restore and remove the guard. Recovery records are stored in C:\ProgramData\JZBApps-RadeonMemoryGuard.

Build

Requires Windows PowerShell 5.1 and Inno Setup 6. Signing also requires Windows SDK SignTool and the project signing identity.

powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\tools\Build-Release.ps1"
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\tools\Build-Installer.ps1" -SelfSign

Privacy

Guard state and recovery files stay local; there is no automatic diagnostic upload. Manual RAM-backend installation can download its pinned package from GitHub. Review support reports before sharing; AMD software has its own privacy settings.
