2Gb on this dual-core 11.6" ultralight. As I'm typing this, I have the usual ridiculous number of programs open; four browser tabs open in Firefox, a media player open in Explorer, two instances of Microsoft Word, a My Computer window, and a Windows Media Player movie open. No issues, as always. If there's a limit to how much I can run/have open, I haven't found it yet.
My system tray is always as empty as I can get it though, the Windows Action Center and Security Essentials are the only two programs there.
11.6? let me guess..HP pavilion dmz1?
Nope, the now-discontinued Acer Aspire 1410, Intel 1.2 GHz. I have to say the 11.6" size is dead on perfect for me, you can carry it with a textbook or two, no carrying case required, but it doesn't look as dinky as some of the true netbooks.
4 GB on my HP ProBook 4320s Fits pretty good for me, i have many programs on my computer running 24/7 :thumbsup:
24/7? i almost dont even want to leave my computer on past 3hrs without using it unless i get lazy turning it back on.
32-bit or 64-bit? 32-bit only maps out something like 3GB and the rest is wasted. 64-bit can handle considerably more than that.
I have W7Ultimate 64-bit on a desktop running with 2GB of RAM and it chugs along just fine. It could use more but it works for what I need it for. One of these days I'll upgrade it to 8GB when I convert it into the HTPC that I originally built it for.
32-bit windows can only recognise up to 4gb of ram minus whatever graphics memory you have. so 32bit windows with a 1gb graphics card could only use 3gb of the ram.
64-bit windows can utilise much much more ram, 128gig+.
