im ram short with my 8GB atm, i could only pop 6apps of mine and it'll hover 65-75% ram usage with that, at best i could pop 8apps in total without freezing my system and it'll top at around 90%. and since the itx board has only two slots of ram i'd need a pair of 8gb sticks to get over 8gb.
edit: oh yea, i've always wanted to get a system with 32gb ram, gonna make a ramdisk of 20gb and do a raid-1 with the ramdisk, theoretically it should be the fastest possible raid there is.
Seems to be quite excessive, what are you doing which is eating all of your RAM? Even when running steam, vuze, all canon printer utilities, ASUS AI Suite, AMD OverDrive, Hamachi and extensive load on my FireFox browser I can't consume as much as you do, even if I run a game like Battlefield 3 I just can't get over the 4GB that I have

Honestly, it... can't... be... done


EDIT: It may have been caught in a bad moment. Usually it only takes up to 10% CPU usage, which it doesn't right there on the picture, maybe it was opening something new lol.
Here I am running A LOT of tabs, three games (all connected to servers and running, all with max settings etc.), while seeding, monitoring and even overclocking the system, I even have my coding program open, Foxit reader, viewing an anime in windows media player, Microsoft Word is open, CPU-z, Origin, Steam FTP Client, Canon MyPrinter utility and a whole lot of other stuff. You can see that I am totally running 103 processors, where windows only needs about 35 to run, the remaining processors is just programs and games.
And I STILL can't fill my 4GB, it still feels just as smooth as if there was nothing open, and I am even running on mechanical hard drives in RAID 0.
I'd say it is quite an achievement to fill over 8GB.
I have even tried with Blender too, it still won't fill those damn RAM.
I was thinking of making a very small 300MB ramdisk, maybe, as you say, two with 150MB, then make a RAID array out of them. Just not sure if that is actually possible.
In my experience RAID 0 is faster than RAID 1, you also get more space with RAID 0.
