What is Vista's limit on amount of RAM?

I recall reading something like XP only allowed for up to 4 gigs of RAM. What is Vista's limit? I am getting the Vista Home Premium 64 bit. The Mobo I have now supports up to 16 gigs tops. I am looking at getting possibly 8 gigs of RAM eventually, but will Vista support that? What is Vista's limit on amount of RAM?
Yeah Vista 64bit should support 8gigs with no problem. its just 32bit operating systems that wont recognise past 3gigs of ram.What is Vista's limit on amount of RAM?
Vista 64bit will support as much ram as you want. The 4gig limit in xp was more because of the 32bit nature of the os then anything. FWIW, home basic supports up to 8gb, home premium up to 16gb, and the rest up to 128gb.
just letting you know Rikuna your wrong.. Vista 32 can support 4 gigs of RAm and see them all now. That SP pack version 1 or w/e made it so that you should be able to...
That's pretty awesome. And good Ram is so cheap now. How could I not pass this up? :D

Vista 64 supports up to 128GB RAM if I remember correctly, so it depends on your mobo;)

I just read up on it and sp1 will indeed see all 4gigs now. lol always a good thing to know.
I wonder how long it'll be before we have an OS and motherboards that support the maximum 16 exabytes that a 64-bit system is capable of using. :P
sp1 will display 4gb, but doesnt mean youll actually use it. you have to consider the amount of vram that is subtracted from the ram total once the limit is reached

Vista 32-bit is still limited to the physical 4GB RAM limitation, with the exception of CPU's that support PAE in chipsets that support MMIO remapping.



With MMIO remapping enabled, then you can move those reserved I/O addresses onto the extra bits of addressable memory a CPU would have, so that the first 4GB of addressable memory that you're normally limited to is available to you, the user. But this is the same thing with Windows XP (32-bit).



Vista 64-bit will only support a different amount [url=http://www.tomshardware.com/reviews/vista-workshop,1775-3.html]depending on your version[/url].

Home Basic was 8GB.

Home Premium was 16GB.

Business, Enterprise, and Ultimate support 128GB of RAM.



XP x64 supported 128GB of maximum RAM, too.
