CPU core problem

Dmac9244 · Apr 10, 2014

My computer has a 6-core CPU, the AMD 6100. Now, I know that windows task manager should say that this is actually 3 cores, 6 logical processors, which should be correct. Actually, it says 1 core, and 2 logical processors. I noticed this recently, and in the past it has said the before mentioned 3-6 combo. Is this a BIOS problem? I'm wondering why my CPU is not being used to its full potential. Is there any way I can test if all cores are working? I'd really like to know why this is happening...

Oh. You might want to know some more...
I have a windows 8.1 computer with these (simple) specs:
AMD 6100 CPU @ 4.2 Ghz
BIOSTAR TA970 motherboard
Corsair CX 430 M
Cooler Master Hyper 212 EVO CPU fan
AMD (Why can't I remember this!?) HD7850 GPU
Some generic DVD writer combo disk drive
2 Hard drives- a 1T backup HDD and a 750 GB HDD SDD combo

CPU-Z also says 2 cores.

Here's a copy and paste answer I gave to someone else just the other day:

winkey+r, type in "msconfig" and hit enter, click the boot tab, click advanced options, make sure Number of Processors is unchecked. Click ok, then click apply, exit and restart.

Once restarted all 4 of your cores should be enabled and will show up on programs like real temp like this:

Hope this helps you out as well!

I am sorry to say that this solution didn't work. I believe it's either a BIOS thing, or a problem with the cores themselves. Is there any way I can do a test of all the cores on my computer?

You can reset your bios settings by clearing cmos. Just remove the battery for 1min (cpu is off) and start back up. You can go into bios and return default settings as well. Please update us! Hope that works then! Also consider updating to the latest bios.

I do have the latest BIOS, and it's a bit harder than that to reset my BIOS. I have a jumper, and this jumper is under my GPU. I'll get back to you as soon as I get to doing this.

Be advised you may lose any overclock settings you have saved. Just a precaution. Perhaps screen shot or write down your settings if you have an oc setting saved in your bios.

LOL, I fell for that one too when I installed my Xeon. Previously having an I5, I set it to use 4 cores, little did I know that was a maximum of 4 cores, so my Xeon showed up at 2 cores, 2 thread!

Well... Currently overclocking is happening through AMD CPU Overdrive. It's probably not the best way, but it works. Can you tell me how I can overclock in the BIOS? I have a BIOSTAR TA970.

I recommend finding a detailed guide for your specific motherboard if possible. In the mean time this video is a good place to start learning:

Also I found this:
http://www.overclock.net/t/946407/amd-motherboards-vrm-info-database/0_100

I haven't read through it in detail but you may find it useful as well.

Resetting the BIOS worked! Thank you for your help, I probably wouldn't have thought of doing that. Probably because I'm not thinking about it that much.

jnewegger23 · Apr 10, 2014

I'm glad we helped! Now go have fun!

Dmac9244 · Apr 10, 2014

I noticed in the first video you gave me that the guy's BIOS is very graphical in the way that it has those tabs and everything. Is this specific to that motherboard, or can I get that?

jnewegger23 · Apr 10, 2014

It's probably specific to his board.

Dmac9244 · Apr 10, 2014

That makes sense.

Okay... Overclocking over here now, In HWMonitor, should temperatures for the Motherboard TMPIN2 sensor be hitting over 60 degrees C during Prime95 Stress test, at 3.8 GHz CPU Speeds? All my other temps are fine, this one is just bothering me a little bit.

jnewegger23 · Apr 13, 2014

As long as it's not that high during normal load (gaming etc) then you're good. Prime 95 is abnormally tough. Not the worst temp I've ever seen but you don't want to stay there for sure.
