Does windows XP 64 support quad procs?

Does windows XP 64 support quad processors?

[ripken204]

um.. well i dont see why it wouldnt, just make sure that ur processors are 64bit.

[Innocent Devil]

why not ???

if u have dual Opteron X2

or Dual Xeon Dual core

that support X64

[cluberti]

Windows XP x64 is limited to two processors, but it counts by socket, not by core. Therefore, two dual-core processors would show up and work properly as 4 processors in Windows XP x64. However, if you install XP x64 on a machine with 4 (or more) physical processors, you'll onlly see and be able to use two.

if i only had sutch a system LOL

but in the end it only would have about dubled the price for buying it...

i found that my computer (to have the exact same specs ans my current machine but with 2 instead of 1 cpu would have cost me over 400 euro extra... (E500- x 1.25 = $625 usd)

so i as, why the hell would have such money but is unwilling to spend the extra $$ on software... as even the a low-budget quad-core machine (4x 1.8ghz) is way beyond any requirements for a home office pc...

unless you want to build yourself a realtime airplain sim in your hobby-room...

cluberti- do u have any clue why that is? how about 32bit, how many can u have for that?

[cluberti]

Same as with 32bit - XP is limited to 2 processors for licensing reasons, not technical (same as the 10 inbound connection limit). However, processors are licensed per socket, not per core. Therefore, dual proc dual core will indeed yield 4 processors in Windows XP, x64 or x86.

[ripken204]

well its just that ive seen what i thought was xp with 16 processors, unless thats MS server?

[allen2]

XP license is for 1-2 processor(s). 2003 entreprise license is limited to 8 processors. I'm not sure if the datacenter license can support more.

[Innocent Devil]

physical processors not cores, isnt't ????

Windows Server 2003 x64 - Processor Support

Supports up to 4 (x64 architecture-based computer with Intel Pentium or Xeon family with Intel Extended Memory 64 Technology, or AMD Opteron family, AMD Athlon 64 family)

Windows Server 2003 Enterprise x64 Edition - Processor Support

Supports up to 8 (x64 architecture-based computer with Intel 64-bit Xeon, 64-bit Pentium, AMD Opteron, AMD Athlon 64, or compatible processor)

Windows Server 2003 Datacenter x64 Edition - Processor Support

Support up 64(x64 architecture-based computer with Intel Pentium or Xeon family with Intel Extended Memory 64 Technology, or AMD Opteron family, AMD Athlon 64 family, or compatible processor)

x32 Editions listed below.

heres the support,

Xp home - 1 physical 2 virtual

Xp pro (and 64 bit) - 2 physical 4 virutal

2000 pro - 2 physical or 2 virtual

2000 server standard - 2 physical or 2 virtual

2000 server advanced - 16 physical or 16 virtual

2003 server standard / small business - 2 physical or 4 virtual

2003 server enterprise - 64 physical or 128 virtual

a virtual cpu would be from hyperthreading, not dual cores.

[ripken204]

now by virtual do you mean hyperthreading? or do you mean dual/quad core?

[Aegis]

Hyperthreaded/physical cores counts as virtual processors and will appear to Windows as one physical one.

2000 pro - 2 physical or 2 virtual

2003 server enterprise - 64 physical or 128 virtual

a virtual cpu would be from hyperthreading, not dual cores.

2003 Datacenter Edition supports 168 Physical Processors and I think 672 Virtual Processors. It's only limited to that because of Hardware addressing!

This would be a VERY quick machine (Expensive as well!)
