Extended memory 25
8 Additional functions
8.1 Autostart and InstantOn
By combining the 47.3 Autostart and the 47.4 InstantOn functions, the RAM
drive is turned on automatically at the startup of Windows. This is useful for ap-
plications such as caching (49.3 Cache) or for the dropping of temporary files:
after the system starts, a fresh RAM drive is available for temporary data. Data
from the previous session is automatically and ultimately deleted.
In combination with 48.4 Persistence, there is another application: in this case
the RAM drive can also be used for non-volatile data (for example, work files, or
files that are delivered through a 49.7 Web server).
Activate the Autostart function as described in 44.2 Autostart and the InstantOn
function as described in 45.1.3 InstantOn.
8.2 Extended memory
For 32-bit Windows systems, Miray RAM Drive Server can use the upper half of
the 4GB limit, too. The size of the usable memory depends on your version of
Windows:
{
Windows XP (0,5 – 4 GB)
{
Server 2003 (4 – 64 GB)
{
Windows Vista (1 – 4 GB)
{
Server 2008 (8 – 64 GB)
{
Windows 7 (2 – 4 GB)
{
Windows 8 (2 – 4 GB)
Hint: A Windows kernel patch that removes the 4 GB limit for 32-bit
versions of Windows Vista/7/8 can be found at http://wj32.org/
wp/2012/12/26/pae-patch-updated-for-windows-8/.
The 64-bit versions of Windows support 8-4,000 GB of memory. Details on the
supported memory are available on the Microsoft website at: http://msdn.micro-
soft.com/en-us/library/windows/desktop/aa366778.aspx.
For 64-bit Windows systems, Miray RAM Drive can use the memory according to
the corresponding edition (see 41.4.5 Editions comparison).
Important: It may be necessary to manually activate the Windows PAE
mechanism on 32-bit Windows systems, in order to use more than 4 GB
of memory (410.4.3 RAM cannot be fully used).
