You should contact the author of these utilities to see why it reports such. I didn't see HT until the higher 2 GHz versions. Look to intel.com to see what's up with that model number CPU.
I have a couple of different utilities that show my P4 Willamette 1.5 GHz as a HT proc, one of these utilities is the Mainboard DMI tool that came with my mobo, a Gigabyte 8INXP.
But even though this windows utility identifies it as HT capable, the option to enable HT does not appear in the bios menus.
Anyone have ANY info about this subject ?
