[SOLVED] Hyperthreading

[dawnofdusk]

Hi,can someone tell me how to disable hyperthreading? I have 2 cores and 4 threads

 

[Mr.Spock]

you just need to go into bios and disable HT.

Waste of time...(short of the possibly rare singular objective of making an older i3 slightly slower in pretty much ...everything

Not just slightly, especially in modern games you will lose a lot of performance.

guys , maybe he needs to disable HT for a homework or any other reason than gaming...

 

[dawnofdusk]

i have laptop and i wanna disable hyperthreading there

 

[mdd1963]

search the BIOS for this option...(hopefully, the option was excluded)

(Dare anyone ask what the intended rationale/reasoning is for disabling HT?)

 

[cryoburner]

Disabling Hyperthreading on a dual-core processor is only likely to hurt performance, and won't likely improve battery life or heat output much, so there probably isn't much point in doing so. The point of Hyperthreading is to more efficiently run a second process thread on each core when needed.

Just for Fun, I disabled Hyperthreading on my younger brother's pc.. on i3 6098p. Then whole pc become 1.3 times slower in any tasks.. and gaming become unacceptable..
So don't do it..

some Apple O/Ses run more stabile with HT turned off

Where did you get that from ?

Many older games will tell you to limit core usage because they were massively single threaded and the pc's insistance on using multiple threads often causes issues. Affects mainly the older DX9 stuff.

Unless there's an issue with the computer or some app you're using that you can nail down to HyperThreading, there's no real point in turning it off.

An app shouldn't care that any of its threads are running on another CPU thread (actually, I don't think apps even have access to that kind of information). The only thing that would happen is a performance loss if the app is stupid easy to run on a processor and shuffling it around is adding to its latency.

In which case all you have to do is limit the processor affinity.

 

[Karadjgne]

Exactly. That's what happens with those old DX9 games, and changing affinity to 1-2 threads for the app itself would be far better than intentionally handicapping a cpu by disabling the HT.

any number of Hackintosh threads

any number of Hackintosh threads

that does not make the original APPLE not stable under HT

 

[Mr.Spock]

read some Avid threads before bark, just because you haven't encountered a situation doesn't mean other folks don't have insight into specific cases.
