imdisk windows 10

[phillip moulton]

Have 20 gig ram. Installed imdisk v 2.0.9 it did create a stable "Drive R" in virtual memory.
However its only allowing a 8 meg size.
imdisk -a -s 8G -mX= -p "fs:ntfs /q /y" is image file
if I try to create a new vertual disk in physical memory even as small as 4 gig it says not enough storage
if i try to create it in vertual memory the param is incorrect
cannot open drive for direct access
cannot save image. peremission refused
I can open the drive and it created a 4meg temp file inside the 8 meg drive
Windows is a 32 bit 10 pro and system is showing installed ram as 20 gb (3.43 gb usable)

The driver does not handle unmanaged memory. Therefore, the maximum usable physical memory for a ramdisk is 3.43 GB, and even with a large swap file, the maximum usable virtual memory in 32-bit is always 4 GB (per process).

There is no workaround with ImDisk, because it would require a major change in the driver.

The alternatives are:
- To use a ramdisk that allows to use the unmanaged memory (but there are some rare cases of incompatibilies with some drivers).
- To use a 64-bit version of Windows.
- To use a 32-bit version of Windows Server which allows to use more than 4 GB of physical memory (depending on the version and the license). With that, you can create a ramdisk larger than 4 GB because only a small part is accessed at a time in the case of a ramdisk created in physical memory.

Of course, the most simple and clean solution is a 64-bit Windows.
