I'm not sure, the reason I asked this question is, sometimes when I am running a program which needs a lot of RAM memory my computer hangs up. I can only assume that there is too much going on in there. Also a couple of years ago somebody on the forum suggested installing a Ram Disc, this I did and it is now under a folder "Ram Disc (C:) but all that is in there is hundreds of Cookies.
Just had a look at my setup,have currently got 512mb of ram,and because of what ACOLYTE said,had a look at my mobo.Imagine my surprise when it says it will support upto 1gb of ram.So if Ram Idle doesn't work,agree with ACOLYTE,put more in.
I was in the same boat a few weeks ago, i only had 512 of DDR333 in my machine, my programs were hagning/crashng so i turned to RamIdle, wasnt too bad but still seemed to hang the computer when "Attempting" to free up ram...
I bought 1GB (2 x 512) of DDR400 (didnt know my board supportred it lol) and it really did make all the difference, definatly worth investing in, iv had no problems since and had no need for RamIdle :)
