Strange happenings: Enabling hyperthreading on the bios for gx270 is
resulting in rapid crashing and freezes. The processor is P4,
(hyperthreading obviously!).
The bios seems happy enough.. so you can actually image a computer or run
diagnostics.. 16 bit 32 bit everything works.. but windows hangs or crashes
depending on the wind direction.. any ideas?
Bios already flashed to latest version and the chipset is up to date as well.
 
Since you didn't mention what operating system you are using, I'll state the
obvious that Windows 2000 doesn't support hyperthreading.
 
sorry.. xp sp2 clean install.. no upgrades..

Are you sure about that? I think that while Windows 2000 does not
properly identify HT processors it will nonetheless properly utilize 2
logical processors, it will treat them as individual physical processors.

I'm using Windows XP professional but... with regards to win2k pro:

You appear to be correct! There is no documentation that says no way to
win2k pro or server working with HT. I was looking into something else and
found a document that refers to HT in use with 2k pro and 2k server/server
advanced, and there is no mention that it's a problem.
 
Yes, it seems to me that Windows 2000 can use HT but... it doesn't do
the best job of it, XP is better suited for these processors.

Did you find a solution to your problem? You might want to ask in one
of the XP newsgroups, you might get better results there.

Thank you John.. no solution but I seem to have something...
HT crashes windows even if it's a fresh installation from the microsoft CD
Diable HT in bios and no more problems... of course xp sees 1 processor only
and your are out of luck with HT.
I'll post there to see if anyone can confirm or correct me!

Open device manager and expand "Computer". Does it say ACPI Multiprocessor
PC?
