I'd like to buy some more RAM to set up a ramdisk cache for startup. My PC is always plugged in, but I may be moving it a few times, so a simple dual installation may not work as smoothly.

I'd like it so that the PC boots from the Ramdisk first and if it's emptied or corrupted, it boots to and copies the startup data from the ssd?

Is it possible to do it this way? In what way can I set it up?

Windows 7 64-bit, i5 3570k, currently 8GB (2x4GB), adding any amount of ram recccomended

They work very well indeed.
They are faster than most SSD drives when it comes to opening or running many programs.

I would say 16Gb is middle of the road when setting one up.
32Gb or more is better.

The only slow point comes when you shut the system down though.
Because you have to wait for say example any contents of the ram drive in the system to be written to the SSD.

If I set up a Ram disk with a normal hard drive I would not bother, it would slow everything down.

To be honest if you set up a ram drive then to get the use of it, most times it should never be turned off.

Anything in the ram drive will send an image of the contents to the SSD. and save the current state.

When you set up a ram drive, it reserves part of your system memory for the use of it.

As you know system memory is even faster in speed as any SSD.
But system memory is classed as volatile memory.
Meaning when power is lost all data is wiped.
That includes a restart of the system since the memory is always flushed clean. And when the system is completely powered down.

When you create a ram disk all it does before exiting is save the contents back to the SSD drive or hard drive and places it back in the system memory just after windows has loaded with the space allocated as the ram disk.

There is no data there like said on a first power up or restart of the system.

So how could you ever boot off it ?
