CPU Multiplier Changes~~

Sup guys~


Just wondering,

I have an overclocked E8400 running at 3.6 [400 x 9]
but I'm just sitting here looking at Core Temp [the application] and watching my Core's [#0/#1] frequency changing...

looks like this at first:

[-] Processor #0
[-] Core #0
- Frequency: 2400.03MHz (400.01 x 6.00)
- Bus Speed: 1600.02MHz (400.01 x 4)
- etc...
[-] Core #1
- Frequency: 2400.03MHz (400.01 x 6.00)
- etc...


then changes to:

[-] Processor #0
[-] Core #0
- Frequency: 3600.05MHz (400.01 x 9.00)
- Bus Speed: 1600.02MHz (400.01 x 4)
- etc...
[-] Core #1
- Frequency: 3600.05MHz (400.01 x 9.00)
- etc...



Keeps changing back and forth while I'm looking at it...
is this normal? or is it a motherboard feature? like power saving or something?

thanks in advance~

Its a power saving feature, if you use CPUID to watch it you will also see that the voltage changes when it does that, the lower voltage means lower current which in turn leads to less power used.

Thats Normal dont worry.
Saves power, but also lets your CPU run cooler which leads to the fan not having to spin as fast which then leads to less Noise.

A truly great feature.
