Disable hyperthreading on a GE70 20E

Hi all,
before starting another flame war on hyperthreading (HT): yes, I know what it is. Yes, I'm certain I want to turn it off. Reasons below.
On my previous laptops (both HP) turning it off was about as easy as going to the BIOS and disable the hyperthreading. I've been through the complete Aptio setup utility that was installed on the laptop, but there's no option for disabling the hyperthreading to be found. I can find it in the online manual of Aptio, but not on my computer.
Does somebody have an idea if it's possible to access that option without having to flash the BIOS? I'm not keen on doing that on a laptop for obvious reasons...
Rationale for turning of the HT:
I run multiple single-threaded programs for advanced statistics and modeling. Right now my 4-year old HP with an i5 dual core of a previous generation outperforms my brand new MSI with an i7 quad core 4th generation when running the models. I bought this laptop to avoid having to connect to the HPC for every model I want to run, but for the moment I'm still losing more time waiting on the results than on that old piece of craHP of mine.

The other option is to just do it within Windows. Which is probably even easier.
Control Panel->Power Options->Change Plan Settings (for whatever power plan you use)->Change Advanced Power Settings->Scroll down to Processor Power Management->Maximum Processor State->Change each to 99% instead of 100%.
I guess this disables TurboBoost and not Hyperthreading.

MSI GE70 20E - Crackling Audio

I have an MSI GE70 20E laptop. I have constant crackling from all audio devices. I have tried headphones, USB headphones, internal speakers, and HDMI to a TV. All of these still crackle during any type of playback. I have tried reinstalling drivers for audio and video and I have uninstalled and reinstalled sound blaster cinema. I have tried disabling my audio devices from the system devices menu one by one. Nothing will get rid of this stupid crackling. I have noticed that it is worse when I am doing something more demanding, like playing video games, but it is always there. Someone please help me fix this.

Same Problem here. My name is Sebastian and I am from germany so please forgive my spelling errors. I did buy a MSI GT70 20C (from Bios) with Windows 8. I did upgrade to Windows 8.1 and have so far no Problems with the machine beside the sound cracking and popping. I can even run a CD without that noise. Like the fellow comrade who did open this thread I did try everything to solve the Problem.
Please Help me! What Information do you need to solve the problem?

In Yosemite, how to disable hyperthread ?

Hi ~~~
I use macbook pro 2011 late and yosemite.
I already use disable hyperthread.
But upgrade to yosemite, hyperthread is not dead
In Win7 (bootcamp), hyperthread is still alive.
I want to disable hyperthread.
How do i do ?
Please Let me know this method...
Have a nice day....

The same happens in Mac OS 10.8.5.
Edit:
It seems turning OFF "Open Documents as Tabs" in "Prefs>User Interface" fixes the problem for me.

System running hotter after disabling Hyperthreading!???

Hi,
I've been running my 875P in a system quite happily for the last few weeks and the Thermaltake Spark 7 has been keeping the CPU nice and cool and a decent 30c but after installing updated drivers for a modem here i found that the system crashed unless i disabled Hyperthreading - obviously the drivers don't get on with HT enabled...
Anyway, since disabling Hyperthreading my system now runs at a much warmer 42c! which is a hell of a difference from 30c average temp.
Would disabling Hyperthreading make this much of a difference ie would the CPU get hotter as its doing more work or somthing?
Its a P4 2.8Ghz 800fsb btw.
Any ideas?

yeah, BIOS v1.8 made no difference.
I'm running StatBar as i usually monitor performance and the temp is hovering around 42c with 0% CPU useage.
Hmmmm... this sucks.
Well, its the poor drivers for the modem i blame, as everything else worked with HT enabled and ovbiously it would be enabled if the drivers worked properly.
I'll only have to put up with it for a couple more months as i'll be getting dsl here and so a new modem will be going in.
I don't like it running that hot though, but its the noise from the fan thats annoying me more than anything! ;-)
So you say look through the other threads? So would you say that disabling HT in any MSI BIOS makes the CPU work harder or hotter etc is this right or would disabling HT on any mobo behave in the same way?

GE70 20E WLAN Erratic and Slow.

I just got a brand-new GE70 20E laptop. Unfortunately I cannot get more than 5mbps download speed over the Wireless LAN. Ive been using Speed Test and sometimes it kicks to 25mpbs but then it looks like it's slowly being throttled back to 5mbps.
I know it's not my router/network as none of my other devices are experiencing this problem. I've tried updating the drivers, bios, firmware and even tried updating to Windows 8.1 and I'm still having this issue.
Please help. If I can't get this fixed by tomorrow, it's going back.

What WLAN adapter do you have?

Permanently disable hyperthreading

I am a software engineer with a startup that makes a mathematical optimization system (linear and integer programming). Our software is already multi-threaded, and it runs much faster when hyperthreading is disabled. This is true on all platforms we've tested, including the 2009 'Nehalem' Mac Pro.
In OS X, I know you can temporarily disable hyperthreading through the Processor preference pane, as well as through the hwprefs command in Terminal. However, hyperthreading is turned back on if you resume from Sleep or reboot OS X. And worse, I cannot figure out how to disable hyperthreading if I boot into the 64-bit kernel.
Bottom line: is there a permanent way to disable hyperthreading on the 2009 Nehalem Mac Pro? On a Windows or Linux system, I know that I can disable hyperthreading in the BIOS; I'm looking for something equivalent for a Mac Pro. Thanks.

You're aware though of how effective CUDA is for compilers, computational and scientific and anything parallel I would assume.
I constantly hear about linux performance being better, and I think Windows 7 has eliminated a lot of issues and better optimized.
And then, software development 101 is here:
http://discussions.apple.com/forum.jspa?forumID=728
Intel works closely with, and has updated their compiler libraries but then it takes time to actually learn how to use, and I often get the feeling developers are being pulled away to work on the latest iGadget and iOS and a really optimized Mac OS X for Nehalem etc once Snow Leopard is put to bed - is further out and lower on priority.

Want to disable hyperthreading on MSI A6200

I have a MSI A6200 (Core i3-350M etc.). I would like to disable hyperthreading to get lower latency for professional real-time audio use [1]. I think hyperthreading is enabled -- at least, Core i3 is a dual-core chip and Linux sees four CPUs.
I see lots of threads on the board about enabling hyperthreading, but information about disabling it is hard to come by. I had a quick look in the BIOS settings, but didn't see anything obviously related to hyperthreading or SMT.
Also, if I have to flash the bios to get this, and I want to go back to hyperthreading = enabled later, how?
Thanks,
James

for low-latency applications, i strongly suggest to disable hyperthreading: it
may increase throughput, but at the cost of latency. some time ago, i have done
some benchmarks on the effects of hyperthreading on the scheduling latency of
the os. it was raising the worst-case latency by about 250 microseconds. (for a
block-size of 64 samples at 44100hz, it would reduce the performance in the
worst case by about 20%).
btw, i doubt that hyperthreading will speed up any number-crunching application.
from my understanding, it is better suited for server/database workloads.

What's current BIOS version installed?
Look in BIOS Setup, System Information.

Fn touchpad Disable/enable not working on Msi GE70 20E

I recently got a MSI GE70 2OE 011NE with Windows 8, when i got it the Fn key wasnt working properly, some of the shortcuts worked, but to disable/enable touchpad didnt, i then downloaded the touchpad driver from this website, and then it worked.. then i updated to windows 8.1.. and after that once again it didnt work, but now it seems like the fn key doesnt work at all.. and my touchpad was disabled when i updated, wich means i cannot enable the touchpad again now.
i tried both touchpad drivers from this site, for both win 8 and win 8.1, wich didnt work.
What can i do to make the fn key work ?
update: apparantly some of the fn short cuts works.. for ie. sound, brightness and backlight keyboard brightness.. just not the enable/disable touchpad :(

Try doing the EC reset procedure....
1. Turn notebook off.
2. Remove AC adapter.
3. Remove battery.
4. Let the notebook sit there for about 20 minutes.
5. Come back, insert battery.
6. Add AC adapter.
7. Power on and see if its working now.

How do I disable Hyperthreading in 10.6.7 on my 2011 MacBook pro 2.2ghz quad?

I'm rendering a scene using Maya 2011, and it's only using two of the four cores in the batch render. I've read that Maya doesn't play well with Intel's Hyperthreading, so I want to turn it off while rendering. There isn't any processor preference pane, so I don't know how to do that. I've read it can be reinstalled from Xcode, so I downloaded it, but I've searched it up and down and can't find anything about processor or CPU preferences.

You better know what your doing
Lets see far as I can tell installing Xcode installs CHUD tools which you can set via the command line hwprefs
If you got Xcode 4 installed, do a 'man hwprefs' and see if it pulls up the manual.
If so the command is
hwprefs -v cpu_ht=false
hwprefs -v cpu_ht=true
(last one turns it back on)

Ge70 20e not utilizing 750m gpu

Hi I just bought a new ge70 everything was running beautiful until yesterday. Games where playing greaton about medium to high settings. Yesterday while trying to can some unessasary backround prossess I think I disabled something I sshouldn't have. Anyway after going to services and restarting everything in there things seemed to be back to normal. When it wasnt I coulnt access nvidia control manager go online or even get audio to work. Now I have all that stuff running ok again my performance in games has completely tanked and nothing I do (lower quality ingame) force use 750 in 3d nvidia settingson each game etc seems to fix the problem. I have a suspicion that its trying to use the intel card instead of the nvidia one. My question is if I was to redownload the new nvidia drivers for it should this fix the motherboard selecting the correct gpu for the right applications like it was? I have very limmited data where I am atm and want to know if it wont be a waste of precious data to do so.will that reset it back to the way it was

Possibly you disabled another service you should not have disabled.
Check whether you have NVidia Display Driver service runs?
otherwise I suggest resetting as possibly you disabled some services which may be needed in the future.
A tip is when you want to disabled some service, rather than putting as disabled, set as manual instead, in case another service need that.

MSI GE70 20E Touchpad problem

Hi, I have a problem with the new touchpad driver. After the latest update for Elantech touchpad there is problem if usb mouse is connected then disconnected touchpad stops working. I connected usb mouse again and went to check touchpad settings and there under Elan tab there is check box where description is something like "if usb mouse is connected disconnect touchpad automatically" (sorry for the bad translation but I use finnish windows)
If you uncheck the box you can use touchpad but its always on. Fastkey (Fn+F3) doesnt work if box is checked.
I did reset the old driver and touchpad works as it is supposed to but isnt driver updates supposed to be better?
Anyone else have the same problem?
I use Windows 8.1

Excellent!
Glad its sorted, MSI recommend you run that once every 3 months to keep your battery in best shape
