Can't enable HT?

[MmmSkyscraper]

Due to slow SETI times, I've been advised to check if HT is enabled. The machine's a laptop with P4 3.06Ghz Northwood. I don't see two CPU graphs in Task Manager, and SiSoft Sandra states that HT is currently disabled (or the OS doesn't support it (not true as I'm using XP SP1)).

I can't enable HT in the BIOS, it looks like this. Here's the info I've got:

Board model: N251S6
BIOS manufacturer: American Megatrends
BIOS ID: 63-0620-009999-00101111-040201-SiS650
BIOS version: 07.00T
BIOS date: 04/02/01

As the date was so old, I've tried upgrading to see if I could get new features. All I can find is an upgrade for the system BIOS from Uniwill which I installed but there's no changes in the menus... I tried the MBID tool from the AMI website but that gave the following:

---
ALERT: This BIOS has been identified as Toshiba BIOS!
Please contact Toshiba for motherboard support ... http://www.toshiba.com
NO STANDARD AMIBIOS IDENTIFICATION STRING DETECTED.
---

Odd as all other apps report it as American Megatrends?! 😕

Also, I read that HT only kicked in at 800Mhz bus speed. Is there any truth to this as mine is set at 533?

If somebody can help, I'd appreciate it.

are you using Home edition by any chance?

The reason the AMI bios didn't work is most likely because the laptop is OEM, and they often times have custom BIOSes.

all 800MHz, and the 3.06 (533) P4 have HT.

I'm definitely using Professional... The laptop is a rebadged Advent, made by Uniwill.

Guess I'm stuck without HT then, even though the CPU is capable of it. Thanks for the help.

Yup, in CPU-Z your cpu logo is like THIS your cpu is with HT and it should be like THIS in BIOS if your chipset support.

Sad news is a quick glance at your laptop manual, I found your laptop chipset is SiS645DX+SiS962 which is not support HT. 🙁

AMIBIOS is always too simple (lack of functions) for power user to tweak for extra performance. That is the only limit, but at least you try to find out.

Thanks for clearing that up! I'll make sure I'm more careful when I get my A64...

XP home supports hyperthreading, so that wouldn't be it anyway.
