    I have upgraded my server from 2008 r2 to 2012 and one thing I noticed, it's not utilizing the second processor (second physical socket), further investigation got me confused. Please refer the picture above.


    NOTE: this processor DO NOT SUPPORT hyper-threading; hence there should be only 8/8 not 4/8 or 8/16/

    From msconfig Boot|Advanced Options check the number of processors enabled.

    I understand, but that configuration is not about physical CPU units. It's about Threads.

    to justify, I have shown an example between the server(on the right) and my PC(on the left). My PC has 3930k which is 6/12 CPU.

    also NOTE: for some reason the server is only showing two processor (it was showing 4 instead some time ago)

    You may need to check with the mobo manufacturer about firmware compatability.

    I think that's irrelevant. As it did work with 2008 R2.

    I am pretty sure it's windows problem.

    Hi,

    Though it worked with Windows Server 2008 R2, it doesn't indicates it's a os related problem. It may also relate to hardware compability with Windows Server 2012. For this kind of issue, we suggest involve hardware vendor for further investigation.

    I agree with Ruby.  If the BIOS is not up to date to support Windows Server 2012 you can have all sorts of anomalies.  That's why vnedors are constantly updating their BIOS - to make it work with the changes in the operating systems.

    Another to check would be whether or not you have core parking enabled on your system.  I have never used it because I do just about everything on virtual servers and that means you keep the host at full power.  But core parking, in essence, diables cores as the load on the system goes down.  From your first image, it looks like you are hardly running anything on the system, so if care parking is enabled, it might have turned some cores off.  Change the power setting to maximum and see if anything comes back.

    But my first action would be to check for the latest BIOS.  Even if it appears to be working for you, if the vendor has a BIOS for 2012, there is a reason they released it.

    Have you installed the manufacturer's motherboard drivers yet? The ones that come with windows might not support dual socket functionality. I'm less prone to thinking that it's a BIOS issue, myself, but that doesn't mean it's impossible. The fact that the full 8 cores are showing in Device manager suggests that the OS *is* seeing them, but is being stopped from accessing the second socket. This may be due to a driver issue.

    Did this server come from the manufacturer with 2 processors or did you add one at a later date.  If you added it at a later date, there could be a processor version or stepping issue that Windows Server 2012 is more picky about that Windows Sever 2008 R2 was not even though they are the same speed and model.   Saw something similar in a HP DL360 G5 a few years ago.

    Please run the most current BIOS and Firmware updates for your server system.

    Also, verify the settings in the BIOS to make sure that legacy SMP settings (for older Linux kernels and the like) are _not_ enabled.

    Verify the Hyper-Threading, TurboBoost (5506 may not have), and C3/C6 states. CPU does not support the first two. Also, ARK shows TXT is _not_ supported so there may be some issues with certain server components.

    NOTE: And this is very important!

    Your snip of the Hardware --> Processors shows 8 processors. So the OS IS seeing both CPUs.

    CPUz has a CPU selector in it. Your snip of CPUz is showing ONE CPU. Make sure you Right Click and RUN AS ADMIN on CPUz or it may not poll for CPU information correctly.

    Your Task Manager has many views for the graphs/performance counters. Make sure you select the Logical Processors view to see all of them.
