I have Pentium D CPU, which many Windows utilities like cpuz, wcpuid,
everest identify as D 930 (Dual Core, 3GHz). From Intel site I find out
that it has no HT feature, nor Windows XP identify it as HT.

Why do I have "ht" flag in cpuinfo?
-----------------------------------

The "ht" flag merely means "I know how to report hyperthreaded logical processors if I have them." My Woodcrest Xeon 5110 and my Athlon64 X2 both have the "ht" flag, and correctly report the zero hyperthreaded logical processors they each have.

Thanks, Chris.

Am I right that is chipset on mainboard, who is saying - "I know....", not CPU itself? Is it better to switch off HT support in BIOS?
Is it possible to generate CPU name as: "Pentium D 930" in /proc/cpuinfo?
On the other server I have some 2GHz HT Xeons which can't be identified on Intel site because of strange naming pattern.
I tried to find any utility for Linux to solve this, but it looks like everybody are using /pros/cpuinfo, which is not enough :)
