Software to disable hyperthreading

[Dhruv Ghayal]

Is there any software through which I can disable hyperthreading in laptop i7. I know the bios method which I use on my desktop but my laptop bios are good for nothing they can show only temperature and battery level only. 

 

Please don't ask me why I want to disable hyperthreading.

what are you trying to achieve with disabling HT?

I think Intel Extreme Tuning,  but not sure.  Why would you want to doable hyper threading? Not going to criticize or belittle you, but have context to what your goal is.

Tiwaz I live in India and it's summer time here. I have Asus fx553vd laptop with i7 7700hq, whenever I play AAA games on it, my cpu package temperature rises upto 89*C. I am using coolpad but it can decrease temp by 2 to 3 degrees only.

Wish I knew of a way too, since depending on tasks I toggle it on and off and going into bios is a pain.

 

The only workaround I can suggest is that if you're running tasks which are adversely affected when HT is on, you can work around it by manually setting affinity. I do it manually each time in task manager, but there are probably better ways. That is usually enough to nullify the degradation from HT.

Ryujin2003 I tried xtu but it's not giving me full control on my cpu. I can't even tweak voltage or multipler

[Altecice]

The BIOS is your only option. You cannot tweak HT on the fly, Windows will not know how to cope with loosing half its threads.

It can't be done via software as far as I know.

Disabling hyperthreading should not make a significant difference in heat. 89C is fine for an intel cpu, not ideal but not dangerous either. Many laptops (cough macbooks cough) let it go up to 99C and throttle.

Pretty sure it does, there's a reason why i7s run hotter than i5s usually and need more voltage for the same clocks.

Yes, but it's pretty small. Lowering voltage is a better way of lowering the temperature when possible.

rather than disabling HT, and btw I doubt it would matter, you should look for ways to better cool that laptop

you could look into

• cleaning the fans and radiator for dust build-up
• replace the stock TIM for something much better - do not even think of liquid metal types unless the heatspreader is Nickel plated
• invest in a laptop cooling pad, example http://www.ebay.co.uk/itm/Laptop-Cooling-Pad-USB-Notebook-Cooler-Mat-2-Fans-Slim-Tray-Fits-15-17-Inch-/162206024901

That's fiiine.

My old i5 spikes to 92°C and from that point the fan gets a kick in the nuts.

 

What i would do is get Hwinfo and look at the Tjunc. (or whatever it's called) it should give you how many degrees the cpu is from thermal throttling.

If your max is 100°C it should say 10-ish degrees so no worries in that case.

 

Have you tried re-applying thermal compound? That sometimes help with laptops that are a few years old.

I have that cooling pad and it's quite crap tbh

It works, i mean it does kick off a few degrees and keeps it just below the thermal throttle level, but i think there are better options than that one.

 

Getting a cooling pad, good idea, but not that one

I didn't meant that exact pad, i only gave an example

he should find a pad that fits his needs and is available in his country

True, and i'm just pointing out that that exact pad just isn't great.

Finding a good one requires research of course

Instead of disabling hyperthreading, try limiting the maximum CPU usage.  Go into advanced Power Options and either edit the maximum frequency or the maximum processor state.

 Games need more Ghz than cores if I am not wrong. No games need more than 4 cores, infact some new games also can't utilize full 4 cores.

 

I have i7 3770k with gtx 960. I disabled 2 cores (4 thread) on it and tested Raise of the tombraider and guess what it was working as usual as it was with 4cores(8 thread).

maybe you can open up the fan and give it a good clean up or even reapply newer better thermal paste

hmmm, though i want really bother even if it gets hot since if it overheats you can RMA it. The manufacturer has to make sure that it can run properly under more extreme conditions as well, if it gets too hot, it will just thermal throttle

You only have two cores. And every game from the past decade has used multiple threads. Not many games are optimized to use more than 8 threads though. 

 

Anyway, this is an issue of thermal throttling. At those temps, it will automatically be lowering the frequency. My suggestion is to just try it out. Cut back 200MHz and see how it runs.

What do you mean by "you only have 2 cores"

Too bad. But laptops are known to run hot. You are fine with 89C unless its throttling. Which I doubt since its brand new.

Don't disable HT. Use Intel Extreme Tuning to disable Intel Turbo Boost and do an undervolt of yes core offset. In my MSI GS72, this drastically improved thermals.

Exactly what I said. You've got a dual core CPU. Watch this to learn how Hyper-threading works:

Edit: Scratch that, you've got an HQ model. I thought it ended with a U. Almost all laptop CPU's are dual core.
