Windows 2003 DataCenter x64 supports up-to 64 physical processors. Support Microsoft
Now what does this exactly mean ? Number of logical CPUs or the number of physical processors i.e. four intel i7s (Logical CPUs here will be 8x4=32)
And if its logical, what will happen if the windows is installed over more than 64 processors, will it not detect or will it detect but will be unable to use ?
This should mean number of sockets, irrespective of the cores. Windows will use up to the maximum of those populated sockets. – None – 2012-06-14T06:24:28.147
That means there is no limitation on the number of cores ? – Basit Anwer – 2012-06-14T06:45:24.487
There's always a theoretical maximum, but if you're talking Data Center Edition, it's academic anyway. Can you afford 64 x 10-core CPUs? And if you could, would you put them in one single chassis running one single OS? I know I wouldn't. – None – 2012-06-14T09:15:28.497
Suppose a scenario of 4 CPUs with 10 cores each with HyperThreading enabled, what would be the effect if using windows 2003 ? (4 x 10 x 2 Logical Cores) – Basit Anwer – 2012-06-14T10:35:54.463
