It is not your CPU or your Windows version. The fact that RAM FS runs well and produces those benchmarks proves that our driver is fully compatible with your processor. Windows Safe Mode excludes our driver by design.
Safe Mode is a diagnostic and recovery mode. Its entire purpose is to boot Windows with the minimum set of Microsoft-supplied drivers needed to get the system running - nothing more. That way, if a third-party driver is faulty, misconfigured, or preventing a normal boot, the user can still start the machine and fix it. To make that guarantee, Windows loads a fixed whitelist of essential drivers in Safe Mode and skips all third-party drivers unless they've been explicitly added to that list. So our RAM Disk and RAM FS driver not appearing in Safe Mode isn't a fault - it's Windows doing exactly what Safe Mode is meant to do.
RAM Disk v25.12 happened to load in Safe Mode because its engine was registered in a driver group that Windows already trusts. In the newer 26.x releases we changed how the driver is installed, and a side effect was that it dropped off that trusted list. And RAM FS, being a brand-new product, was never on that list.
If you specifically need them in Safe Mode now, you can add them to the whitelist yourself:
1. Open Command Prompt as Administrator (Start → type cmd → right-click Command Prompt → Run as administrator).
2. Paste the below code depending on the product you are using and press Enter.
For RAM FS:
reg add "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\ramfs.sys" /ve /t REG_SZ /d "Driver" /f
reg add "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\ramfs.sys" /ve /t REG_SZ /d "Driver" /f
For RAM Disk v26.x:
reg add "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\SPVVEngine.sys" /ve /t REG_SZ /d "Driver" /f
reg add "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\SPVVEngine.sys" /ve /t REG_SZ /d "Driver" /f
The lines with
Minimal are for normal Safe Mode. The lines with
Network add Safe Mode with Networking - skip them if you don't use it.
3. Reboot into Safe Mode. To confirm it started, run this command for RAM FS:
sc query ramfs
or this for RAM Disk:
sc query SPVVEngine
You should see STATE : 4 RUNNING.
P.S. We are very glad you are enjoying RAM FS
