The RAM storage will consume 115-120MB of physical RAM (a figure that is slowly but surely increasing), leaving you with approximately the same physical free RAM as a 256/256 split, and an imperceptible performance difference.Good to know. I tried 128 and didn't notice a performance difference with the OS loaded into RAM. Changed to 192 w/ noram as per your suggestion (all my *res settings are 720), more RAM for the system/artwork is always a good thing. Thanks!
IMHO loading SYSTEM into RAM is not worth it as in many ways it leaves you worse off with reduced free RAM and/or gpu_mem, and the supposed performance gain of having SYSTEM in RAM is very slight, if it is noticeable at all (I can't tell any difference).
My advice is gpu_mem=128 in config.txt (or 180+ if using high resolution image/fanart in advancedsettings.xml), with "noram" added in cmdline.txt to prevent SYSTEM being loaded into RAM, even when there is enough free RAM available. This should ensure there is far more free RAM available to XBMC and Linux for things like buffering and avoiding out of memory situations.
