Disabling HyperThreading on Inspiron 5150

Hi,
I have a new 5150 and I need to disable the HyperThreading in the BIOS. When I boot I hit F2 and get into set up but I can't find HyperThreading on any of the screens. Is it called something else or am I in the wrong place? Is HyperThreading even accessible on the 5150?
Thanks so much for your help.
Regards,
Greg Remillard

If you had a HT cpu, there would be a BIOS entry.  If you are positive you paid for and got an HT cpu, then make sure you are using the latest BIOS.

Check the Task Manager (Ctrl-Shift-Esc) and in the performance tab you should see two graphs for the history of the cpu - if you have an HT processor.

Check you have the latest BIOS but also check the downloads page for a new driver for the P4 in winXP.

Hope this helps.

So any Inspiron 5150 with a 3.06GHz CPU, BIOS A26 & the Microsoft P4 driver download from Dell should have the HyperThreading feature available?

Thanks...

Only if you ordered and paid extra for the HT cpu.

No idea...it was a system from the Dell Factory Outlet ordered on October 5th 2003;

johnallg, good to see that you're still active on the forums-I'm back after a long absence, & remember you from the old Inspiron 4000/8000 days...

Once I recieve the system (tomorrow), any definitive way to determine whether the CPU is the HT one? BIOS/Win XP/SiSoft Sandra Diagnostics?

The order code for this system is Item # W0986, CPU is part # G1278,  Processor 80532 if that helps.

Thanks!

Yup,  I recognized your username.  Welcome back.  The latest BIOS will show an entry for HT toggling on one of the pages of the BIOS if you have an HT cpu.  I would think the Intel Processor utility would also id it as HT capable.
