Difference Logical processor

Hi,

I have a questions regarding Our Server DL 360 Gen9 with windows 2012 r2 installed.

On one server the processor detect :

Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz, 2397 Mhz, 8 Core(s), 8 Logical Processor(s)

while other server with same type and same OS detect:

Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz, 2397 Mhz, 8 Core(s), 16 Logical Processor(s)

Is there any setting or something that I missed, or it comes with the board it self?

Thaks,
