Default So I noticed something funny under Vista yesterday...

This may be somehwhat difficult to explain and I hope I can explain it ok...

The last rig I had is very similar to my current one, only this time I'm running 4gigs, 2 video cards, and 64-bit Vista.

When I exited out of Supreme Commander I believe, and had IE up and I was downloading a WoW patch (Yes, I took the plunge haha), I noticed under system resources the computer was using 2.11 GB or something.

Now before, when I was running 2gigs of Crucial Ballistix, at the same timings and speed, I don't think I ever saw it reach higher then 1.5GB after exiting out of a game, and having IE up and downloading something. (Yes, I know, Firefox FTW, It's what I use on my laptop, I don't use my gaming rig for internet use really)

Since the extra RAM is there, does windows use the memory more efficiently or what?

I mean, doing two similar things, on two similar systems, but it takes up more memory on the 4GB system then the 2GB? Is that weird at all? I mean I'm glad to see it using as much as it can, but I guess I'm just curious how Vista 64-bit uses RAM and how efficiently. Anyone know much about it?

Back on being mobile - ASUS G551- 15.3" 1080p - Core i7 4710HQ - GTX 860M - 16GB DDR3 1600 - 512GB Samsung 850 Pro - Steam ID: TheOtis

Yes, vista uses the memory to prefetch. Basically unused RAM is wasted ram.

Nothing to see here.

Vista will try to load as much as it can into RAM. It will eventualy learn what programs you use the most, and will try and have them ready and loaded in RAM....
