The "256 MB restricted 64bit version" version and the unlimited 32bit version are freely available and can be downloaded from the links within the table below. These versions are full functional. The purpose of the 256 MB restricted version is to evaluate the functionallity before purchasing the unlimited 128 GB version.

Please read the included Instructions carefully before installing the software.

Remarks :

Instead of installing the RAMDisk via the "Add Hardware Wizard" , it is highly recommended to use the alternative "QsoftRAMDiskHelpInstall.exe" installer program that can be downloaded at QsoftRAMDiskHelpInstall.7z . Do copy the five binaries ( RAMDriv.sys , , RAMDriv.inf , RAMDriv.dll and RAMDiskImage.exe ) out of the \ENG , the \FRE , the \GER or the \CHS folder from the installation package into your empty C:\Temp folder. Do copy the QsoftRAMDiskHelpInstall.exe binary into the C:\Temp folder as well and start it up via de right mouse button "As Administrator". This Install helper shall not be used to update an existing installation !

On Windows 10/11 it may become difficult to find back the "Device Manager" with its device tree. This RAMDrivProperties_exe.7z contains two small programs , one for 32 bit (x86) and one for 64 bit (x64) OS versions. When started , the program directly opens the "General" tab of the Winramtech properties. Push the "Change settings" button within the "General" tab before selecting the "Ram Disk Properties" tab to configure the settings of the ramdisk.

Be aware that a 32-bit version of the RAMDisk will not install and run on a 64-bit OS. The 64-bit version of the RAMDisk will not install and run on a 32-bit version of the OS either.

The downloadable 7-Zip packages below contain a RAMDrivDMP.bat that can be used to read the RAMDisk specific registry content, thus without having to start Regedit.exe and to navigate to those specific keys. That BAT file needs "regdmp.exe" ( registry dump utility ) included within the ZIP package, which must reside in the same folder as where RAMDrivDMP.bat has been stored. On Vista and Windows 7 , the RAMDrivDMP.bat must explicitely be started "As Administrator" . Everyone who want to report a problem should provide the ramdisk specific registry content to allow the necessary fault analysis.

People that are interested to use the Enterprise Version 5.3.2.* within PE ( Microsoft PE or BartPE ) may download RAMDriv_5_3_2_X_PE.7z. Details can be read in RAMDriv_5.3.2.X_PE.txt within the compressed file. The 7-Zip contains also plugins for both Windows PE and BartPE. Please notice that the RAMDriv.sys file within these plugins must be replaced with the most actual version of RAMDRiv.sys. The "devcon.exe" program within the plugins does not work on 64-bit OS versions. On 64-bit OS versions , one has to replace it with the 64-bit version of the program that is made freely available from Microsoft. Take also a look at this

Please install and run the "Evaluation" version to check if the RAMDisk meets your requirements before making any purchase.
