Processor and Cache Memory Settings. Part I

Hyper-Threading Function

(Hyper-Threading Technology)

This parameter allows the processor using the Hyper-Threading Technology (HT). It is used in the processors of Intel Pentium 4 and Core i7 and allows providing two command streams by each processor cores.

Possible values:

  • Enabled (On) – the support of Hyper-Threading Technology is on;
  • Disabled (Off) – the Hyper-Threading Technology is not used.

After switching the Hyper-Threading on a quad-core Processor Core i7 will be identified by Windows as octocyclic. But actual productivity depends on the nature of computer usage and may account to several per cent. There will be no speeding at all if the applications which you use are not multi-threaded.

CPU L1&L2 Cache

(CPU Internal Cache/External Cache)

This parameter switches on or off the cache memory of first and second level which is a part of a central processor in modern computers.

Possible values:

  • Enabled (On) – integrated cache memory is on;
  • Disabled (Off) – integrated cache memory is off that will lead to a substantial decrease in productivity (in several times).

There are separate parameters L1 Cache and L2 Cache in some versions of BIOS.

CPU Level 2Cache ECC Check

This parameter switches on the correction and control of errors in the cache memory of the second level. If you switch on this function by Enabled (On), the operating stability of the system will be increased while its productivity will be a bit decreased. If you switch it off by Disabled (Off), you can increase the system speed.
