Windows 2000 reports 2 processors on PowerEdge 1600SC with only one processor
I have a PowerEdge 1600SC with only one 2.8 Ghz processor.
At this moment the system doesn't have any problems (it's twice as fast compared to my previous machine a PowerEdge 1400SC with one 1000 Mhz processor).
After installing Windows 2000 (without using OpenManage) and SQL Server 2000 I found that SQL Server detected 2 processors. In the system summary Windows 2000 also reports 2 processors: x86 Family 15 Model 2 Stepping 7 GenuineIntel ~2790 Mhz.
Can this cause any problems?
How can I fix this?

LOL! That's because the 1600SC supports hyperthreading. Xeon procs. The OS can see 1 physical proc as 2 logical procs giving you some extra performance.
This is a good thing :)

Hi,
These links from Intel and Microsoft explain the process and licensing issues.

If needed, you can disable Hyperthreading in the System BIOS of the server. Choose CPU information, and under there is a setting for Logical Processor. Disabling that option will turn off Hyperthreading, and your processor count will return to normal in the OS.

Physical and logical processors... I realy didn't kwow about their existence!
We have a SQL Server License for 1 processor. I already found out that Microsoft only counts physical processors for licensing purposes.

Those are zeons.
So why does my PowerEdge 700 with a Pentium 4 2.8Gh do the same thing in Windows server 2003?
I only have one physical processor, BIOS agrees with me.

The Pentium 4 processors in the PowerEdge 700 also support the technology known as Hyper-Threading.
