Windows XP or XPx64 using more than 2 CPU's???
So... according to MS, this is the lowdown on #CPUs supported by OS:
Operating system Number of processors Physical RAM Microsoft Windows Server 2003, Standard Edition 4 4 gigabytes (GB) Microsoft Windows Server 2003, Standard x64 Edition 4 32 GB Microsoft Windows Server 2003, Enterprise Edition 8 64 GB Microsoft Windows Server 2003, Enterprise x64 Edition 8 1 terabyte Microsoft Windows Server 2003, Datacenter Edition 32 128 GB Microsoft Windows Server 2003, Datacenter x64 Edition 64 1 terabyte Microsoft Windows XP Professional 2 4 GB Microsoft Windows XP Professional x64 Edition 2 128 GB Question regarding XP and XPx64... are there any other flavors or upgrades of XP that will use more than 2 physical processors? Yes, I know going to Server 2003 is one answer. I assume this means having a quad core and XP will do you not a shit bit of good...? |

i think microsoft differentiate between cores and physical cpu's, so you could use 2 quad cores with xp

Yeah Grings is right. Microsoft basically goes by the number of cpu sockets. XP Pro will support systems with 2 cpu sockets filled, the number of cores doesn't matter. If they existed, you could run 2 1,000 core cpus on XP Pro.

It looks that way. I got this from a Microsoft “fact sheet”:
" Multiprocessing and multicore support. The platform is designed to support up to two single-core or multicore x64 processors for maximum performance and scalability with no additional licensing cost to customers. " Now… the way I read that, if you have two quad core processors, it will indeed use all eight physical cores. There isn’t much more detail that I could find other than that statement. If anyone has any concrete links, please do share. |

Support isn't a problem, it is licensing. And Microsoft indeed counts on a per socket basis. The discussion started way back with HTT.
