P4S8X-X Hyperthreading

[RJ]

Hi all,

I have an Intel P4 3.06Ghz Hyperthreading Processor running P4S8X-X with
Windows XP Home
(All latest Service packs installed).

Looking at my system:
Windows Device Manager shows ACPI Multiprocessor PC
2 Processors are listed under Processors

So Far So Good. (Apparently XP Home *does* support Hyperthreading)

So why do Benchmarking and Diagnostic Programmes (SiSoft Sandra, Aquamark)
tell me that Hyperthreading present, but disabled?

Additionally, I read that if HT is working properly, there should be two
processor graphs in Windows Task Manager? I only have one.

Any ideas on how to Enable Hyperthreading.
(And yes, it is enabled in the Bios

TIA

XP Pro and Home both support HT. Home
doesn't support 2 physical CPU's. Only
XP Pro does.

Did you install the CPU while XP
was installed? Or did you install the
CPU before you installed XP?

If you DID install/replace the CPU
while XP was still installed, that maybe
why there's only 1 CPU graph in Task Manager?
