Ryzen 1600 2 Cores 4 Logical Processors

BaylissLad · Aug 13, 2017

Hello. My new Ryzen 1600 is only using 2 cores and 4 logical processors (threads). I have the latest BIOS update and my previous CPU was also AMD (AMD Athlon X4 860k).

My motherboard is the MSI B350m Gaming Pro, if you need that.

probably not the news you were hoping for.

@SoggyTissue My msconfig only goes up to 4 cores, which is currently checked. And I was seeing if there is any other way before doing a fresh install of windows because, knowing my luck, that won't work either.

Is this the same install from your previous 860k build ??

If so new windows install mate , its still using core/ thread specs from your old CPU.

there was a time i loved installing ... used to do it every week. now its just a pain in the a$$. i feel your pain.

BaylissLad · Aug 13, 2017

Okay. Why would it be showing 2 cores 4 threads by the way? My old CPU was a quad core? @madmatt30
Yeah, pretty annoying @soggytissue

(assumption): could be that windows defaults to a duo core system, detects a hyperthreading capable cpu and throws out this result.

we all know how sloppy windows can be, i wouldnt bet against this being true.

Look the windows msconfig boot advanced options option.
That sets how many threads windows will use.

BaylissLad · Aug 13, 2017

@Geofelt I should have 12 threads, aswell as 6 cores. http://prntscr.com/g7yppi

BaylissLad :

Exactly, can you change the number 4 to 12?

BaylissLad · Aug 13, 2017

geofelt :

No, I would have shown the drop down but Lightshot never wants to come up when i hit Print Screen so I had to click it manually. It only goes up to 4

geofelt · Aug 13, 2017

For whatever reason, windows is detecting a 4 thread cpu.
Is your motherboard bios up to date?
There have been many issues with ryzen motherboards.

There is also the possibility that the processor is defective and is not supplying the correct thread info to windows at boot time.

Do one thing, run Cinebench and see if your CPU is getting an average-ish score, or maybe a UserBenchmark test to see if your CPU is at or above average. If it is scoring fine, you at least know only the info is wrong, but the processor still has 6 cores and 12 threads.

BaylissLad · Aug 13, 2017

Shektron :

Got a score of 404. From other benchmarks on the internet, people are getting about 1000.

@geofelt My BIOS is up to date.

Thanks for the help guys. I will be reinstalling Windows and seeing if that fixes the issue.

Shektron · Aug 13, 2017

If reinstalling Windows doesn't fix it, your processor might be defective. Make sure none of the CPU pins are bent, and there is no damage to the processor. If it still doesn't work, you'll most likely have to RMA it.

completely new chipset/cpu...

YOu can try looking up how to do a sysprep, or,...

Nuke and pave, delete partitions, quick format/reinstall fresh! (the sure way to not be using old/incorreect chipset/cpu drivers, default MS drivers, etc...)

urbancamper · Aug 14, 2017

If you are not using a fresh install of Windows the problem is something you made yourself. You can not expect to change platforms from Intel to Ryzen and have windows give proper readings, or for that matter expect all cores to work. After your fresh install, all will work fine.

Don't forget to download the latest drivers, and use them, not the ones on your disk.

Reinstalling Windows worked! Thanks guys!
