    I have a 4 x 10 core (80 threads) machine. I've installed windows server datacenter 2012 and now i'm only able to use 2 cpu. Windows server datacenter 2012 only allows 2 cpu per license key. I do have 2 license key but i got no idea where to input the 2nd key. I'm only using 1 license right now. When i use cinebench, the cpu usage stays at 50% in the task manager.
    I've been searching everywhere for an answer. Can anyone help me? o_O

    I'm not wrong.. Yes it supports 64 physical processors but you'll need to buy 32 licenses to be able to use the 64 processors.

    I think it is something else with your cinebench. You assign one key to the server and that is it. You allocate the second key (in other words buy it and hold on to it). You do not enter a second key or 32 keys anywhere, only one key goes into the server, the rest you hold for legalities.

    The question on why your Cinebench is not showing properly I cannot answer that.

    Correct, the restriction is "on paper" ONLY, it is not enforced in any way by the OS

    Yes!

    i'm unable to get 100% cpu usage from softwares i'm using like 3ds max and cinema 4d. The softwares are supposed to allows max cpu usage. Windows server 2012 isn't allowing this. Without hyper-v installed i'm unable to use more than 50% cpu usage. With hyper-v installed i'm able to use 64 threads only on the OS. I'm not using any VMs and don't really need more than 1 user on my OS..

    Any info about this issue would help me greatly.

    Thx

    Get a little app that produces constant CPU traffic, or use any single-threaded app and insert an endless while loop. Start it 10 times. Then open the task manager, enable all CPU views. Watch if all your CPU cores are busy. Does this help?

    don't know if this will help but I' using a Dell Precision T5500 Workstation with Xeon E5620 CPU and WS2012DC I can see in the Processor 8 CPUS and I can utilize more than 50% when I'm using divx converter. I activated this windows using KMS

    Maybe the reason you are not utilzing more than 50% of your CPU is something else is the bottleneck like your Harddisk. I use a 512GB Kingston SSD as an OS harddisk

    I hope this will be of help

    In programming terms endless while loop means execution of the program until the stop-conditions of the loop will never be done (program will run forever until you will not stop it manually).

    A quick way to get the 10 while-loops, is to open 10 powershell windows and type/paste: while ($true) {}
