Question New i5 13600k uses only 2 cores

[Eddie Mitza]

I've recently build a new PC, but the system uses only 2 cores/4threads out of the 14 cores/20 threads my i5 13600k has.
I also have an issue with my new 2x16 GB Corsair Vengeance 6400 Mhz CL 32 1.4V RAM sticks, which emit a high pitched noise when enabling XMP in the bios
Is the CPU broken? What about the RAM problem? Help.

Did you do a clean install of OS, or put a drive in out of your old rig?

Try resetting the motherboard if the above is not so.

I'm using the old drives with the old OS.
How do I reset the motherboard?

Either by clearing CMOS, or removing the battery on mobo.

Do a clean install and see if the issue resolves.

By "Either by clearing CMOS" do you mean by pressing the CLR_CMOS button on the mobo?

That would be the one, but I suspect this is an issue caused by using your old OS without performing a clean install.

 

[Dark Lord of Tech]

Usually a clean install of the os helps.

God, I hope that's the case. I've been scared s***less.

It is a bit confusing.
Unless you have a workstation, you will have only a single processor.
Your 13600K has 6 performance cores and 12 performance threads.
You also have 8 efficient cores.
Likely, your windows is set to use only 2 cores, perhaps you reused your windows c drive.

If you leave the number of processors box blank, you should activate all of your cores/threads.

Yes, I am using my old windows C drive, but my previous processor was an i5 7600k which has 4 cores and 4 threads and it worked fine.

I've already done the msconfig thing, it only shows the 4 threads there.

You might be able to correct it by refreshing your chipset driver, however I would expect other bugs and issues to be a constant factor moving forward.

Do yourself the favor, now, and just wipe and reinstall OS. Future you will appreciate the efforts of past you.

 

[Eddie Mitza]

Okay, it's fixed, for now. I've done 2 things, I've let the msconfig number o processors box unchecked and I've also uninstalled the old mobo's app center and installed the new one's instead. I don't know which of the two fixed it, but I'm happy it did.

Now there's the XMP profile issue which baffles me greatly.

I was about the reinstall the OS after a back-up anyway, but I thought I would use the old OS to test the components and such. I didn't anticipate the old OS can impact the hardware so much.

 

[punkncat]

To be fair, if this was just a 'normal' generational jump from one architecture to another refresh (on Intel) it probably would have worked fine. The issue is that the 13th gen isn't a refresh of 7th, it is 'wholly new' since 12th and the drivers have no idea what to do with it.

Make a clean install.

You moved 6 generations up. I would rather surprise if you don't have any issues without a clean install.

Your problems or at least some of them might be resolved, but still new issues might arise. Make a clean OS installation.
