CPU not clocking down after Win 8.1 update

[Van Diemen]

As title.

Prior to the Windows 8.1 update, my PC would auto adjust its CPU clocks.

after the the 8.1 update CPU is stuck @4.5MHz.

anybody else experienced a similar issue?

It wont clock down as in 'Cool n Quiet' or you cant change the clock in bios?

I have win 8.1 but haven't noticed anything. My CnQ is switched off though.

PC specs or WTF? really mate. You may need a bios update tbh, there's one for AMD CHV owners already.

I have two CHVF-Zs to update

Haven't really noticed anything different though.

Wont clock down in Windows.

have now set the BIOS to stock settings and the CPU still will not clock auto down in Windows (remains on the 3.9MHz turbo clock)

Is your windows power scheme set to high performance?

 

[ALXAndy]

No bios updates so for now you're SOL

Is your windows power scheme set to high performance?

Nope, that was the first thing I checked.

It's set to Balanced

A friend had this problem and he reset his bios to default like 3 times then booted, windows then downclocked...he then overcloked as normal and it was OK. Was very odd when he told me.

Even so when you go to advanced settings, what is the minimum processor state set at?

In a similar boat here. Windows 8.1 and CPU stays on full whack all the way through. (Different setup obviously).

Funny thing is, when I go through the Advanced Settings the minimum/maximum processor state is missing from the options where it is normally found. So I can't even tell it not to use as much CPU power.

CPU-Z just shows the CPU jumping from 1.1Ghz (x12 multiplier) and 3.7Ghz (x37 multiplier) (CPU is 3820). I'll check for a Bios update to this (Asus RIVE), but this seems really weird.

Did a straight upgrade and not a reinstall, so that might have impacted on a few things.

Yep even after I have set the advanced settings.

minimum CPU state is set to 5%, but I have tried all sorts of settings combinations.

Was all working well before the 8.1 update.

I'm stumped

Tried restoring it to before the update and seeing if it happens again after you update?

The Windows 8.1 update done some odd things to my machine. Had to blank it and start from scratch and put everything back on. Aside from a couple of reg edits it was working like Windows 8 again after this.
