Unlocking Turbo Boost

[UnlimitedB]

The reason why the cores are sitting at 1460Mhz is because of the reset of the power management options. Under default high performance makes the CPU stay at 100%.

I do find it weird why it would report no frequency.

I constantly do maintenance every month or two to clean up the dust in the fan and on occasion change the thermal paste. I will re-seat the CPU, but this will happen abit later as I am in the middle of a long report.

However in my opinion it is not a hardware issue but something software (Bios) related as I can see the processor functioning correctly when ThrottleStop is running.

Hi,

My mistake, I'd forgotten the power option was set to high performance - does it clock at a fairly steady 931MHz when set to Balanced?

Open windows Event Viewer, open up Windows Logs and select System - do you see any acpi errors relating to the embedded controller?

Yes out of 58,066 events, 30 are errors relating to ACPI.

There are alot of other errors too, should I be worried about them

I havent made much use of the event viewer in the past

Hi,

If the acpi errors releate to the embedded controller, this is more than likely a glitch in the way HWiNFO is accessing it - it may also explain the occasional 0MHz reading for Core0.

Regarding the other errors, post back with details of the most frequent ones.

I agree that it would be extremely useful to have access to more options in the bios menu and it would certainly help in trying to identify what's causing this issue, however I'm not aware of the current bios versions that are available, restricting the cpu - I will look into this further though.

Can you let me know if your Windows 7 installation is oem version or retail?

Hello

Windows installation is retail

There is a critical level error from source Kernel-Power (41), which relates to a reboot after a crash, however I don't think I have ever experienced a crash on this computer, maybe its something to do with the system not shutting down properly.

The other most repetitive is an error from source Disk (11) - the driver detected a controller error on \device\harddisk1\dr1

There are some other ones but they are infrequent and self-explanatory

In the 'warning' section there is something which is bothering me, there is constantly an error again by Kernel-Power (37) which states 'The speed of processor 4 in group 0 is being limited by system firmware. the processor has been in this reduced performance state for 71 seconds since the last report.'

The processor number and the time changes from one error message to the other.

Hi,

That Kernal Power ( 37 ) error pretty much goes along with the original problem, but not what's causing it ( heat would be the obvious answer, but the temps shown on HWiNFO don't show a problem ) - if you run a ThrottleStop log file, does it show the throttling to be caused by clock modulation and if it does, what type?

Can you give me a link to the page for your current bios version F.1D

In your Power Options, temporarily turn off Link state Power Management for both battery and plugged in.  While you're in the power menu, just check that the Maximum Processor State is showing 100% for plugged in and battery.

In ThrottleStop I just set the multiplier to Turbo and Turn the program on.

The clocks on stand alone are at x11 = 1.4Ghz, but it should be at least x12 =1.6Ghz, with the Turbo they go up to x20 = 2.6Ghz

I don't touch the clock modulation, it is set to 100%, the throttling is not caused by the clock modulations, but from the multipliers as it is intended.

I don't quite remember where I got that Bios from, http://www.mediafire.com/?pda8228gp9lmj9k

I am pretty sure the original source is HP but they have not put it up on this model's page.

The power options are already set as you have described them.
