CPU Hyper-Threading

Common Options : Enabled, Disabled

Quick Review

This BIOS feature controls the functionality of the Intel Hyper-Threading Technology.

The Intel Hyper-Threading Technology allows a single processor to execute two or more separate threads concurrently. When hyper-threading is enabled, multi-threaded software applications can execute their threads in parallel, thereby improving their performance.

The Intel Hyper-Threading Technology is only supported by the Intel Pentium 4 (officially only those 3.06GHz and faster) and the Intel Xeon processors. Please note that for Hyper-Threading to work, you should have the following :-

- an Intel processor that supports Hyper-Threading
- a motherboard with a chipset and BIOS that support Hyper-Threading
- an operating system which supports Hyper-Threading (Microsoft Windows XP or Linux 2.4.x)

Since it behaves like two separate processors with their own APICs, you should also enable APIC Function in the BIOS, which is required for multi-processing.

It is highly recommended that you enable CPU Hyper-Threading for improved processor performance.
