Missing CPU threads

[hacksmack]

I just recently bought a core i3 3240 for my dell optiplex 7010 sff. But in task manager it is showing up only as 2 cores and 2 threads can anyone help me out? Must mention though I think I have bent some pins on the socket but managed to bend them back as the system still does boot just with missing threads. But when comparing cinebench r15 scores I got 205 which is on par with others. Is there a system bug not showing the additional cores or have I actually broken something. Someone please help

How many logical processors does Task Manager say you have?

Pretty sure the i3s just recently became 4 cores. The one you have is a 2 core with hyperthreading. So 2 cores 4 threads.

 

intel ark confirms:

if it  only state 2 threads then see if you have hyperthreading enabled in bios.

But then shouldnt task manager state the number of logic processors as well?

It only states 2 for the logical processor when Im pretty sure it should say 4.

Might be related to those bent pins you mentioned.

so then I assume it is actually still possible for the pc to boot even if some pins dont work? and im not sure but does hyperthreading affect cinebench scores cause my cpu still scores around the same

Bending pins shouldn't matter, unless you crossed a power supply pin with something.

 

Two places to check would be the BIOS/UEFI to make sure the option for Hyperthreading is enabled and in msconfig -> Boot -> Advanced to make sure that Windows isn't restricting itself on how many logical processors to use.

Ah gotcha but how do I go about with it on the optiplex bios cause it isnt the typical laid out bios choices. I have searched but dont see an option that allows me to unlock the threads.

[NoobCase]

If you download cpu-z how many cores/threads does it show? ( first tab, bottom right corner)

 

again se my edit. Check your bios

[Toasted Waffles]

Your Chip isn't technically a Quad core - It is a Dual Core with Hyper threading. So you will have 4 threads and 2 Logical cores.  I would check the BIOS to make sure the hyper threading isn't disabled - I know on some pre-builts this is the case. I would also double check the pins and see if you can correct them.

Which optiplex?

is it the tick box for number of processors? I have clicked and applied and when restarted the cpu went to 1 core 1 logical processor

This would technically work, but Task Manager will still report how many logical processors there are if they're not enabled.

The chip is a dual core with hyperthreading, but the 2 cores are phsyical processors, not logical. The extra 2 threads are logical processors.

I assume the pins are fine considering it booted without a hitch. Not entirely sure if the system can still boot with broken pins or whether it wont at all

yeah but im still seeing 2 core and 2 threads

Depending on what pins are broken, the PC will boot. Ground pins aren't usually a concern since they're all over the place, but voltage pins and other pins may cause it to not work.

ah okay but that goes back to my previous question. Since I have 2 missing threads shouldnt I be having lower cinebench scores? But my test shows that it performs the same as other unaffected cpu

It would depend on if the other CPU tested was running with all 4 threads enabled.

 

One thing you could do is try comparing directly between another CPU identical to yours with all 4 threads enabled, and see if there's a performance difference between the two. Also check results against an indentical CPU with just 2 threads enabled.

Well I went on youtube to observe the same cpu bench. on the cinebench they used it said 2 cores 4 threads (for me it was 2 cores 2 threads) but both him and I obtained the score of 205

Try finding results of 2 cores 2 threads and see if there's a difference.

alright will have to hunt around thx
