Task Manager not showing right amount of cores.

[Xian07]

Its an old cpu and after a long time i went into the task manager and it only shows 1 core and 2 logical processors even though the intel site mentions 2 cores and 4 threads.

Cpu: Intel Core i5 3337U
Site: http://ark.intel.com/products/72055/Intel-Core-i5-3337U-Processor-3M-Cache-up-to-2_70-GHz

Picture of task manager is included.

Right click the graph, and select change graph to logical processors. Then it'll show you the amount of threads available to the scheduler.


All the best!

Im talking about the amount of cores and logical processors.

i will highlight them in this pic:

 

[Suzuki@1473780084@1473780163]

Oh, my apologies!

It should say 2 cores, 4 logical processors. It's possible that it's a bug in task manager.

Please try checking it again using a dedicated CPU tool, download: http://www.cpuid.com/softwares/cpu-z.html

Report back.



All the best!

Im starting to get scared, cpu-z also shows 1 core and 2 threads.

Core means the # of cores in the processor. Logical processors means # of threads per core. Hyperthreading means 2 logical cores. T/M might not be reading your processor right. if you have a dual core processor. Interesting it is showing the same in CPUID. Yep, something is wrong with the reading of or the processor.
W.P.

 

[Xian07]

But cpu-z also shows 1 core and 2 threads ???

 

[Xian07]

Any suggestions on how to fix it ?

 

[TbsToy]

No, I don't. Test equipment is needed. It appears that the processor is functioning properly based on what T/M is showing though. Maybe just a glitch that doesn't affect the functionality. If it performing well it might not be a problem.

OP, open up the "mainboard" tab and find motherboard make & model. It's possible that you can re enable cores and threads if they're disabled in BIOS. Have you tried restarting your PC, was it working before?

 

[Xian07]

Thx guys i found the solution by myself.

What i did was:
Open run
type msconfig
went to the boot tab
then selected advanced options
then there was a check mark to select number of processors
the check mark was checked and even though it was selected at 2 cores
i unchecked the mark and restarted
and done

THX guys for all your help, but i dont know how those settings got changed in msconfig.

Probably some power saving feature. All is good now?

 

[Xian07]

Maybe i dont know, but yea all is good now thx guys for all the help

 

[Suzuki@1473780084@1473780163]

Now you can finally relax. Enjoy the extra performance, which you didn't have until now. 😛

 

[Xian07]

Lol yea but i have another question,
the intel site says the turbo frequency is 2.7 ghz so whats that ?
does it like get activated under load or do u have to activate it yourself ?

 

[Suzuki@1473780084@1473780163]

Since it's a laptop, it's highly likely that you got some manufacturer bloatware on there which is going to make sure that it's got it's own power saving feature, and probably won't run at the full 2.7 GHz.

A desktop on the other hand, would be default to "Balanced", which is min. processor: 5%, max. processor: 100%. I highly recommend just using "High Performance" all the time, because a lot of power saving features will want to try to lower your hard drive so that access is slower, though saves power.

In some laptop batteries, enabling "High Performance" could damage it, but it's not really an issue in modern laptops I don't think. I do recommend using the laptop with the charger plugged in, in this mode, just in case. "High Performance" is min. processor 100%, max. processor: 100%, and won't slow down other components either.

 

[TbsToy]

That is the turbo boost, (max), speed and it will spool up to that as loads increase. Notice the multiplier in CPUID. No intervention on your part is needed.
W.P.

Oh ok anyways thx for the help im gonna do some tests between (1 core and 2 threads) and (2 core and 4 threads).

 

[maxgoldberger]

You dont understand how much you saved me from not being able to sleep for a week that shit worked and i cant thank you enough <3 you may never see this but i have to thank you some how

 

[Xian07]

I got sent an email. So i did see it. I'm glad that this thread helped you as well

I am experiencing these same symptoms with dual socket xeon 2630v3. I should have 32 threads but sometimes I see 1,2,3,4,5,6,7,8,9,10,12, and 20 threads.
