Titel: Kloksnelheid CPU DS916+
Bericht door: GuidoG op 31 januari 2019, 11:49:40
Ik lees in deze review het volgende "De processor heeft 4 cores en een kloksnelheid van 1,6GHz. Indien nodig kan dit automatisch worden verhoogd naar 2,56GHz."

Klopt dit? Zo ja, hoe zou ik dat dan kunnen doen? Welke gevolgen heeft het?

Dat zal waarschijnlijk wel kloppen. Er staat automatisch, dat doet hij dus als hij het nodig heeft, dus er is geen manier om dit zelf te doen.

Oh aha, dus ik maak er al gebruik van zonder dat ik dat door heb. Dank je wel

Zijn energie en warmte besparende technieken van de cpu.
Als de cpu continue of volle snelheid zou draaien zonder dat het nodig is. wordt hij onnodig warm en slijt dus meer en verbruikt meer energie.

Beetje tech ;) :

Citaat
6.3.5.1
Package C0 State
The normal operating state for the processor. The processor remains in the normal
state when at least one of its cores is in the C0 State or when the platform has not
granted permission to the processor to go into a low power state. Individual cores may
be in lower power idle states while the package is in C0 State.

6.3.5.2
Package C1/C1E State
No additional power reduction actions are taken in the package C1 State. However, if
the C1E sub-state is enabled, the processor automatically transitions to the lowest
supported core clock frequency, followed by a reduction in voltage.
The package enters the C1 low power state when:
•  At least one core is in the C1 State.
•  The other cores are in a C1 or lower power state.
The package enters the C1E State when:
•  All cores have directly requested C1E by means of MWAIT(C1) with a C1E sub-state
hint.
•  All cores are in a power state lower that C1/C1E but the package low power state is
limited to C1/C1E by means of the PMG_CST_CONFIG_CONTROL MSR.
•  All cores have requested C1 using HLT or MWAIT(C1) and C1E auto-promotion is
enabled in IA32_MISC_ENABLES.
No notification to the system occurs upon entry to C1/C1E State.

6.3.5.3
Package C6 State
A processor enters the package C6 low power state when:
•  At least one core is in the C6 State.
•  The other cores are in a C6 or lower power state, and the processor has been
granted permission by the platform.

Power Management
•  The platform has not granted a request to a package C7 State but has allowed a
package C6 State.
In package C6 State, all cores have saved their architectural state and have had their
core voltages reduced to zero volts.

6.3.5.4
Package C7 State
A processor enters the package C7 low power state when all cores are in the C7 State.
In package C7 State, the processor will take action to remove power from portions of
the system agent.
Core break events are handled the same way as in package C6 Stat
