Quad core only works on Ultimate vista

Dual dual-core processors and single quad core are 2 different things.
Windows usually IIRC assigns licenses based on the number of physical CPU's present in a system, not by the number of cores. Single CPU quad cores will probably work fine, but dual processors with dual cores to give 4 cores may not.


Windows XP Home 1
Professional 2
Windows 2000 Professional 2
Server 4
Advanced Server 8
Datacenter Server 32
Windows versions and processor numbers supported.
No reason to expect Vista to be any different.

No idea how it works or will work with Vista, but WIndows XP worked just fine with a single license on my dual Xeon... So that can't be how it "usually works". Just FYI.

Yeah, see my edit 😛 XP Home does 1 CPU, Professional supports 2 CPU's with any number of cores. The basic Windows (Home at the moment, Vista Home - both versions, in the future) supports one, the high end business one supports more.

$400 for ultimate vista...just so it will use the other chip.

i think its insane to not only make us upgrade our hardware for $$, but then to have $$$ for the OS. = more bootlegs and me staying on xp until it drops to $100 😛

dont take things out of context.

Quad FX only works on Vista Ultimate, not quad core.
theres a big difference between 2 dual core processors and 1 quad core.
the difference is the number of sockets.
 
OSes, and many high-end apps are licensed PER CPU, nothing to do with cores.
Please stop spreading mis-information ignorantly.

Am I reading it right that you can have two quadcore cpus with XP professional for 8 total cores?

yes Ill say it again...
OSes are licenesed per CPU socket not by cores. If Intel made a 1 socket, 1,000,000 core CPU TECHNICALLY and LEGALLY it would be ok for XP Home. You could run 2x of those with XP Pro too.
