Cant turn off the Hyperthreading in Bios

[czn0405]

Hi there

I need to turn off the hyperthreading in bios but I can't find where to turn it off, in BIOS there is no such options for me to turn it off, there wasn't even a Category called Cpu/Processor. The bios was Insydeh20 Setup Utility. I am using a Lenovo Laptop, 6700HQ, 16GB RAM.

Hyperthreading is only used when necessary, is there any reason why you would want to disable it?

It assists with you performance quite impressively compared to the i5.

Laptop BIOSes are usually pretty limited, if you don't see anything in there for processor settings or clock settings its likely you can't turn it off (I don't even know why you would want to).

It's about the game crashed to desktop without even an error code, ubisoft support says turn off the Hyperthreading and here I am..

I highly doubt it is anything to do with the hyper theading, are you sure that the graphics card didn't fail or the drivers for them didn't crash.

Ok more useful info there. Yes I have read about disabling hyperthreading to improve performance in ubisoft games (talk about poor programming), also We have had to disable hyperthreading on some servers we run at work to improve database query performance, the reason being hyperthreading tends to cause the cores to lag a bit which can make a significant difference in database queries.

So the idea is not unprecedented. I expressed surprise though since its not a normal thing to ask about, and also as I said with a laptop you may not be able to do it at all.

Whats the exact model of Lenovo, maybe if I can find a roadmap of the BIOS I can figure out how to do it, but its very possible you can't.

Not too sure about this, but if he is running Windows 10, isn't there a manual way of disabling Hyperthreading. Couldn't the Intel Extreme Utility Program or something allow it to be disabled?

In Windows 10 under System Configuration (msconfig) / boot / advanced options you can limit the number of processors but I don't know that that disables Hyperthreading for sure. If he set that to 4 it might do it, not the best way to go but could work.

Intel Extreme Utility

Might do it, I honestly do not use it, its more of an overclocking tool but it may be in there.

Either way the preferred way to do something like this would be in the BIOS.

I thought of the first thing originally, but I tried it on my laptop but it didn't really work, it said the base clock increased but it locked its self before that, so I just ignored that idea. I believe you may be able to do it in the Intel Extreme Tuning Utility program. Guess its something to try.

Obviously doing it in the BIOS would be much better, and can be enabled again eventually and have better access and control. But if that isn't possible then there may be the secondary process.

I just tried Intel Extreme Tuning on my server and there is no setting to enable or disable Hyperthreading, so no that won't work either. looks like BIOS is the only way.

You can set core affinity of the process to use only the even numbered cores, which would avoid using the HT cores.

In Extreme Tuning? I don't see that option anywhere. Or are you saying his BIOS should have that?

''ubisoft support says turn off the Hyperthreading and here I am''

one thing about ubi is that its everyone else's fault but there own and well say anything to push the blame off them .


but then I guess some motherboard do allow you to turn off hyperthreading ??

''Ubi Keiv is incompetent at optimizing PC games ''

like said seems like poor game optimizing ? hyperthreading should be a benefit .

maybe you just got one of them great ubi games ?

like how with farcry 1 they released on DVD and broke / removed the 64 bit support from the installer and only installs on 32 bit windows ? [ works 64 and 32 if you got the CD copies ]

Can do it manually though Task Manager, or download a utility that does it.

I just checked task manager and can't find a way to do this? Right clicked on each process.

OK so I researched the BIOS and found out that yes all those types of options are locked out, there is no way to unlock them. There are folks out there that mod BIOSes and they were unable to find a way to unlock it. Hopefully when Gamerk replies to my post above we have a different option.

Should just have to right-click -> Set Affinity.

I think I found the problem. On my Server (Win 10 and a Xeon E3 1231v3 I go to processes and right click on any process and that is not available. On my work laptop (Win 7 i5-4300u) the option is there. It looks like you can no longer do this in Win 10. Are you running 7 or 10?

 

[gamerk316]

7; must be a 10 thing.

There's a way to do it as a launch option, but IDK what it is offhand. There's also several programs that do this automatically; they can be found easily enough with a google search.
