i recently put in this quad core before i had a dual core but i am now noticing my intel i5 4460 seems slow when streaming and the msconfig is telling me it only has 2 cores. does anyone know what is wrong here?

MrMckelvey,

You've already observed that Windows 10 is still configured for 2 cores in "msconfig", where the "Number of processors" or active cores can be changed. This setting is easy to miss, so you just need to get back to the right place in msconfig.

On your keyboard, press the "Windows" key and the "R" key to get the "Run" window, then type "msconfig" and hit "Enter".

In the "System Configuration" window, click on the "Boot" tab, then click on "Advanced options".

In the "BOOT Advanced Options" window, the box for "Number of processors" should be unchecked, and have a greyed out "1". This is the default...

then i would check the BIOS to see how many cores are reported. it sounds like because you came from a dual core that the BIOS didn't automatically enable the other 2 cores so go into BIOS and enable them or defaulting your BIOS may work too

Check BIOS for system information. How many cores does it report?
I believe you haven't formatted your system after upgrading the processor. First ensure it is truly quad core using BIOS. If it is positive, then format/reinstall your Windows. Otherwise return the processor.

MrMckelvey,

You've already observed that Windows 10 is still configured for 2 cores in "msconfig", where the "Number of processors" or active cores can be changed. This setting is easy to miss, so you just need to get back to the right place in msconfig.

On your keyboard, press the "Windows" key and the "R" key to get the "Run" window, then type "msconfig" and hit "Enter".

In the "System Configuration" window, click on the "Boot" tab, then click on "Advanced options".

In the "BOOT Advanced Options" window, the box for "Number of processors" should be unchecked, and have a greyed out "1". This is the default setting, which means Windows will use all available physical and logical cores.

Regardless of what it says, click on the "Number of processors" box, change the number to "4", then click "OK".

In the lower right side of the "System Configuration" window, check the "Make all boot settings permanent" box, click "Apply", click "OK" then restart your rig.

If this fixes the problem, you should have 4 cores in CPU-Z, and your rig should behave accordingly.
