I7-6700k No Longer Hyper-Threads

Go to solution Solved by Dockmaster,

I still have no idea what happened. I did a full reinstall of windows and all is well.

 

 

Hello All,

 

I've got a 6700k that randomly has stopped hyper-threading. It is paired to a MSI Z170-A Gaming M7 with current UEFI. I've confirmed that both the Windows Task Manager and CPUz both show as 4 cores, 4 threads. I've also confirmed in the bios that hyper-threading is enabled as well as cycled the setting to see if that would resolve. Anyone got any ideas on if there is some sort of hardware failure with the chip / motherboard, or if I've just missed something obvious? 

 

Thanks for any help ahead of time!

Open msconfig and make sure Number of processors is not checked. Push OK and reboot.

Whoops, sorry. Noticed yesterday, however, I know Hyper-Threading was working about two weeks ago when I rebuilt Win10.

OK. I just opened mine to see if there was anything for HT, there does not look to be.

Clear cmos and update the bios.

There is no way to turn on HT in windows.

The only option is to force 8 cores vs unchecking number of processors.

 

To find out if windows actually sees the threads...

 

Open CMD type wmic and hit enter.

The type 

CPU Get NumberOfCores,NumberOfLogicalProcessors /Format:List

hit enter.

Will show number of cores and logical processors.

If it says 4 and 4, it's a bios issue.

I'm assuming you meant 'wmic cpu get...'

That being said, I think this has to be a Windows OS issue...not sure how.

I booted up Ubuntu from a live USB and ran a few commands on that side. lscpu does infact show 4 cores and 2 threads per core. htop not only sees the hyper-threaded cores, but also reports work being done by them. 

 

I've reached the end of my Google-Foo. Does anyone know where/how Windows would be not seeing these, when clearly the Bios / *nix are?

Well that is interesting.

 

I don't do Windows Diagnostics. I believe you are in the wrong section, this is Hardware diagnostics thread. 

 

I am sorry.

Even more bizarre. Device Manager sees all '8' cores.

This is a stupid question but do you have the latest windows update installed
