CPU Speed.

So ok... Here's the deal.

I just installed CPU-Z in order to check my memory timings (since I just updated BIOS, just wanted to make sure everything was ok), so in the process I stumble upon my CPU speed, and it reads ~1358 MHz!.

What is going on?

the multiplier changes under load

So are you saying that I'm getting the whole 2.7 GHz of my processors speed under load?

Hmmm... Interesting.

So what's behind this CPU underclock when not under load? Windows 7? The Processor itself?...

Because I clearly remember that my CPU read 2.7 GHz (using CPU-Z) under Vista 24/7, but this was also under a different BIOS.

there you go. different bios may read it differently, different OS as well

This is usually controlled via bios or some mobo manufacturer software. I think its called Speedstep or EIST. Stress your cpu with some program and see if it bumps it up to the correct speed. If so then what the other poster said is the case. You can usually turn it off in bios if you choose to. Its not a problem to have on, but is sometimes recommended to turn it off if you overclock your cpu.

Thanks for all the help guys.

when you flashed the bios to a new version, it probably started at "optimal settings," which in your case, seems to include as a default setting a cpu throttling feature to lower frequencies during non-load (as the others have stated prior to my post). depending on the bios, whenever you flash, you will have to go back into the bios and reset all of your specific settings back to what they were set at before the bios flash. (my bios, for instance, gives me the option when flashing to erase everything or only update specific items while leaving my changed settings intact).

Hmmm...

The thing is, I'm a big chicken when it comes to BIOS, I only change basic stuff like... Memory timings, Boot order, etc...

I would never mess up with something like 'CPU throttle'.

I'm even scared of disabling AMD's 'Cool n Quiet' feature lolz.

It has to be something new that ASUS wanted to incorporate into their new BIOSes.

EDIT: Thanks BTW.
