RAM drive on Xp 32bit with 4GB ram

[Grinja]

Hi,
I recently read (on the inquirer i think) that if you have 4GB ram and a 32 bit OS you can allocate the extra RAM (The part your OS can't allocate) as a RAM drive .

Anyone tried this or have any ideas of how to set one up?

Cheers

Haven't done it lately, but I've done it before and it works GREAT for certain
things. For some other things it's actually a waste because your RAM is tied up
in the RAM disk instead of free for use by programs that don't use the RAM drive.

Frankly before I messed with that for applications like video games or whatever
I'd try running XP-PRO-64 or VISTA64 and get 8GBy memory and then look at
using a 5GBy ramdisk to hold the majority of the game files or whatever.
Then again you'd probably have some issues with drive letters moving
around etc. too, so that might be a pain in the butt to get setup.

No, you cannot just do that.

1) If the hardware is limited, not even the cpu can reach the lost ram.

2) If the hardware permits it (address space larger than 4GB, and memory remapping), you would need a memory manager capable of addressing more than 4G, 32-bit vista and xp won't do that. So you would need to change something in the kernel for it to work
