How to disable HyperThreading on HP BL660c servers?

You can disable HyperThreading in BIOS

We have HP BL660c server running windows server 2008 R2 and we are supposed to disable Hyperthreading.

In task manager we used to see 64 cores under performance tab.
we required only 32 cores.

- Goto BIOS, select System Options and press Enter
- Select processor options and press enter
- Select Intel(R) Hyperthreading Options and press enter
- Select Disabled and press enter
- Come out of BIOS, once the system boots check in task manger you will see the processor count will be reduced by 2.
