XXHighEnd

Some may wonder how to reduce the CPU frequency. I tried something simple for this :)

I go to Power Options (in Control Panel) and I select "Change Plan Settings" (located at the right of the power scheme that you use).

In the next window that appears, scrolling through the different options, you should see "Processor power management". Open the sub options by clicking of the "+" sign.

You will see "Minimum processor state". Click also on the "+". For the example, adjust the value to 50%.

You will also see "Maximum processor state" sub option. Click on "+" sing, then adjust the value the same as the one you entered for the "Minimum processor state".

Then click "OK".

It worked for me, but at a certain point, even adjusting these to lower values will not really change the CPU frequency. This should be the "lowest" adjustments you can make - possibly because going lower either is a physical limit that the motherboard BIOS allows, or it would need further tweaking directly at the BIOS level...

This will work provided that something was not done in BIOS to "block" the OS from managing the CPU frequency...

If only the BIOS was better explained, it would be easier to do this at the BIOS level. It's the different designations used that are complicated...

EDIT: I have W8, but this should be applicable to W7 the same.

WRONG IDEA !!!

You (and nobody) should do this, because it mangles with XXHighEnd settings and nothing will work, up to burning your processor.

Besides that it doesn't help a thing, like you said it yourself Alain.

More besides that, what you're trying to do is perfectly arranged for by XXHighEnd itself.

Lastly, I am pretty sure you just tried this on a fresh install which makes you look through another glass then when not. But this is a wild guess and a bit unpredictable.

Peter,

I should have precised that I use "No Tweaks" to allow for that... And I understand that there could be conflicts with XXHE if the XTweaks are applied...

I have to admit though that to "force" a frequency to stay at a certain underclocked state eludes me ?

Alain

No Alain. This is about rather complex things and how the OS responds to what and which does not anticipate any mangling from individual elements in there. There is spades more of them and only when they are consistent it is allowed to do it. And then even I am hoping to apply all correctly.

Remember the 100% cpu usage W8 reports ? same sort of thing. And my response to that you also know : I don't use the setting which implies that. Just to be sure, never mind SQ changes to even the better.

Normally I have these kind of responses (posts) when people will mess up their OS unintendedly. This time however they will smoke their cpu. You can if you want, I could have easily with all my own efforts, but others should not experience such a thing.

By the time I know (read : worked on) how you all can set your frequency to 470MHz or whatever it is I can reach, it will be in XXHighEnd or made known otherwise.
Deal ?

Deal :)

Thanks Peter.

Hi Peter,

I have reduced my cpu frequency to 2 Ghz through the BIOS. Is this correct way of doing it or should I set it to the default setting the manufacturer had supplied it with?

I did notice a slight improvement in SQ with the lower frequency as compared to the default(3.33 Ghz, I think).

In my case XTweaks are on as per my sig.

Do it like that is okay Arvind.

Peter

Ah ? Well I have reduced the frequency through BIOS also... My mistake was to think that it would not be harmful to reach the same result through Windows Power Options...

Alain

Would be easier if we have a clear explanation on what can be done and what can´t and if can be done how to do it correctly, if it must be done in the BIOS and not in the OS, with XTweaks ON or not, etc.

Best regards,

Hi,

I'v been playing with declocking for a while since Peter mentioned this a mothe or two ago. Now that the ATx supply problem is fixed I can easily hear the differences of settings.

Rather than adjusting the CPU clock frequency down, I have been lowing the clock multiplier in bios. Standard setting on my PC is 32x giving 3.2ghz cpu frequency, lowering it to 24 improved dynamics detail level and blackness it can go as low as 12 but I'm sat listening to 18 and on my PC, this appears to be a sweet spot. Very nice.

Nick.

Hi Nick,

Thanks for the input. I have to talk myself into being more precise with what I did, because it is the ratio that I turned down to 12, this after moving the AI (ASUS) overclocking from "AUTO" to "MANUAL". I am not sure if that "MANUAL" is a prerequisite, but I did not want the motherboard to go up and down...

Regards,

Alain
PS: Have you tried filters to eliminate noise from DC to DC convertes ? I am not sure I am using the right designations, but I saw this:

Could this be a good alternative to the expensive linear power supplies that would power a pc ?
