Does Windows 2000 Support the new Presler Dual Core 900 series

[WillRichard]

I know XP works well but does Windows 2000 support it well enough as I have some legacy programming that needs Windows 2000 instead of XP. old versions of Visual Studio and other OLE programming. Advise or help? Would it be as fast then if I use Win2k?

It shouldn't have a problem as far as I can tell, as Win2K is SMP aware like XP.

I run an AMD X2 with Win2K and it runs just fine, and as fast as XP.

The only problem it had was with the P4's with Hyper Threading, as it couldn't differentiate between a physical and virtual cpu, which could make some apps run slower.

With two real cores though, thats not an issue.

This is most likely purely a theoretical issue, unless WillRichard intends to use an "extreme edition" P4-D, but Windows 2000 is not "aware" of the change in MS's licensing, such that it only supports two "CPUs," real or virtual (Windows XP is licensed by socket, so dual CPU dual core systems and dual core w/ HT systems are fully supported). This can become a problem, because a Windows 2000 system might see only one real and one virtual CPU on a dual core w/ HT platform, leaving half of the CPU unutilized.

I have no problem with XP actually and have several machines at work with XP but the MS Director wants it in Windows 2000 and we have so many legacy softwares for Novell, IBM OS, and 3270s and updating with XP has in some ways caused problems so far and Win2k did not have this issue. So will Windows 2000 slow down and underutilize the 2nd Physical Core ? As a lot of distributed transactions in SQL Server, Oracle Javabeans need that... 100s of opertons and several Presler 840s I think and 930s or so... I was only wondering... as I cannot use for games anyway.... get the boot!! 8) though I surely would like to try some...

Actually I don't believe that a 2000 system will see one real and one virtual CPU on a dual core HT hardware setup. HT does not support HT so the two cores will be recognized and HT (virtual) will not be. Unless I'm off here... please chime in.
