Hi everyone,

 

has anybody an idea how i can disable the hyperthreading on the Toshiba X20W?

 

I searched the BIOS for an option but did not find any.

There was only an option to disable all cores but one..

Attached are the options of the BIOS i found.

 

Help would be much appreciated!

 

Regards,

Philipp

Not sure why this is desirable, but intel XTU should work

Don't see what you need? Check the Full List or *PM me, if I haven't made it I'll add it to the list.

*NOTE: I'll only add it to the list if the request is something I know I can do.

I want to disable it, because i heard it has quite a lot of bugs and security issues. And i want to see if it really gives me that much of a performance boost or i just don't need it. :)

Where did you here that? There is literally no reason to disable hyperthreading.

 

 

And yes, you will notice a BIG performance dip, especially if you have a low-end CPU.

One of the early fixes for zombieload was disabling hyperthreading,now that I think about it

From what I've heard on most Intel platforms with disabling HyperThreading the benefit to disabling it is negligible or actually ends up hurting performance.

 

As for security there are BIOS updates and OS patches for things like Spectre & Meltdown. The likelihood of you coming across these in the wild are not significant so you're really just hurting yourself by doing so.
