Windows Vista and Intel C1E throttling.

[JN]

Hi Guys,

I've been researching a very annoying problem with Vista and the C1E function on Intel chips (changes multi and voltages dynamically to save power).

On a machine I built for [Ins] we was finding that when idle in Vista his multi would drop from x8 down to x6. Everything throttling related (C1E, Thermal throttling, etc) was disabled in BIOS but this wasn't helping.

It would seem that Vista is so "intelligent" that it looks directly at the features of the CPU to see what power saving features it has, and uses them regardless of BIOS settings (at least on most Abit boards).

We're testing this software tonight to see if it fixes the issue:

http://cpu.rightmark.org/download/rmclock_22_bin.rar

It has the ability to turn off C1E and a whole host of other features on the chip.

Thought this info might help someone

Imma have a butchers at this tonight

Downloading and trying in 10, i had this problem, vista dropped my multi from 9 to 6

Reading around it looks like its been affecting lots of other boards too, so it wouldn't surprise me if everyone on vista is affected but don't realise it.

Let me know how you get on with that soft..

Hmm imma take a look later on

Right well the first thing i noticed is how much more accurate it is than CPUz. It gave a live display of my multi fluctuating. I've locked it now (as far as i can tell) and im reading up on the other more advanced options, looking very useful though. Someone should do a simple registry hack that turns C1E off totally tbh.

Core Name is wrong and is reading the same as Intel Thermal Monitor and the core temp is the same as coretemp (also wrong) so they are obviously using the same sort of script, one that doesnt like E4300s yet

I also cannot tell if the app needs to be running for the changes to remain applied

I'm going to test this on my PC tonight as well, as damn Vista is driving me mad setting my multiplier to x6

Grrr!!!:cussing:

hmm i wonder if thats why my cpu scores on some benchmarks suck so bad buy i havet seen my mhz drop at all in cpuz when its on.

 

[ionicle]

just a thought:

put F@H on

then its at 100% use, and vista can do nothing

Do any of you using vist have issues with aquamark my gpu score will be well over 14k but cpu score drops all way down to 6k were xp they both were over 12k far as i can tell on mine i see no thottling.

It wouldn't surprise me if that's just down to Vista. I always felt like Vista was constantly doing something in the background even when my machine was idle, whereas XP seems to lay more dormant when not being used.

That fancy ass glass effect is to cover up the camera lense that MS is using to spy on you, recording your behaviour.

Conspiracy theories ahoy!

My processor stays where is was put at all times btw

I have SpeedStep & C1 Halt enabled in my BIOS. It doens't bug me. I usually run WCG and that keeps my processor pegged but it's nice when it's just idling.

 

[Toxcity]

Have to love how clever Vista is!

maybe a bit too clever!

 

[Bal3Wolf]

lol aquamark and 3dmark 06 benchmark alot slower for me but 05 03 i got my highest scores ever pcmark 04 was bout same. Ms spying wouldnt be the first time im sure they got a world wide cam network probly.

Can anyone please please please help me with this before I put my foot through my PC (and I'm really not kidding).

Whatever I try I cannot get my PC to use the x8 multiplier, it just refuses to budge from the x6. I'll screenshot every single window if needs be but so far I've had to:

1. Turn off the Windows User Account settings cos it kept blocking the RMclock app on startup

2. Ticked "Enable Enhanced Halt State (C1E)"

3. Turned off "Enable Thermal Monitor 1"

4. Turned off "Enable Thermal Monitor 2"

5. Turned off "Enable Extended Throttling"

Any ideas?

Please help me before I totally go mad!!!

Disable C1E matey - that's what throttles your CPU

 

[NickS]

Ye I just went in BIOS and disabled C1E and SpeedStep and it doesn't throttle anymore. Make sure you have both disabled guys!

For you P5B users, its right under CPU Options (iirc).

change your power management to high performance to. Might try changing cpu min and max to 30% min 100 % max.
