Hi people,

I've looked all around all google search possible and still couldn't find examples of p-states from users using similar processor t23xx(I am using a t2390 1.87GHz), so I came hear to ask for an opinion about my voltages.


here is the results for a sysctl -a | grep throttle:
kern.exec: unknown type returned
kern.cputhrottle_curfreq: 800
kern.cputhrottle_curvolt: 940
kern.cputhrottle_freqs: 800 1067 1333 1600 1867
kern.cputhrottle_factoryvolts: 940 1052 1164 1276 1388
kern.cputhrottle_ctl: 1551
kern.cputhrottle_auto: 1
kern.cputhrottle_targetload: 30


The PStateTable was automatically populated from the ACPI, I don't know but comparing it to the processor specs (http://processorfinder.intel.com/details.aspx?sSpec=SLA4H)
VID Voltage Range: 1.075V-1.175V those voltages (kern.cputhrottle_factoryvolts: 940 1052 1164 1276 1388) seem too harsh.

Is it normal to have these notebook processors exceding their VID for some reason?

I am thinking of setting the PState Table on the Info.plist manually like this:

CODE
<key>PStateTable</key>
            <array>
                <array>
                    <integer>1867</integer>
                    <integer>1175</integer>
                </array>
                <array>
                    <integer>1600</integer>
                    <integer>1150</integer>
                </array>
                <array>
                    <integer>1333</integer>
                    <integer>1125</integer>
                </array>
                <array>
                    <integer>1067</integer>
                    <integer>1065</integer>
                </array>

                    <integer>800</integer>
                    <integer>940</integer>
                </array>
            </array>
        </dict>



What would you guys recomend?

Thank you.

Hello.
You can also use VoodooPower by Superhai. It allows you to override voltage settings diffining a voltage range in the Info.plist.

if I was to use VoodooPower, Do I just need to put the UserVoltageMax/UserVoltageMin setting and it calculates the voltages in between?


example:
CODE
                      
                                <key>UseEfiFsb</key>
                <true/>
                <key>UserVoltageMax</key>
                <integer>[b]1175[/b]</integer>
                <key>UserVoltageMin</key>
                <integer>[b]940[/b]</integer>
                <key>VoltageOverride</key>
                <[b]true/[/b]>
                <key>VoltageProbe</key>
                <true/>  // ---> [b]Do need to change it to false when using the voltage override?[/b]




I do have tried to start using VoodooPowerMini yesterday.. but man, it offer all those override voltage settings and threeshold;hysteresis, but I found it odd that it doesn't have any option on that to show on the terminal all the p-states table it is using, but it do have and option to show just the current one, I think it lacks a complete overview of the kext stats like the one we can have with Intelenhancedspeedstep, plus when I tested it yesterday the notebook became a "shutdown russian roulette" as sometimes it shutdowns ok and sometimes it doesn't that's why I am still using IntelEnhancedSpeedstep

In my view, for my use, the only feature that is better on VoodooPower is the hysteresis value, the one which avoids frequent steppings when the processor don't need it.

Thank you for your input.

One more thing, do you think that those 1.276V 1.388V voltages could have damaged my processor?

thank you.

You could try the new v1.4.9 (get it from project website) which has an option to auto-create a PState table for you if one can't be found through ACPI, or if you supply -autopstate option to the kernel while booting (at the bootloader prompt). The minimum voltage is currently fixed at 984 mV because there seems to be absolutely no general formula to find it. The max voltage is read directly from the CPU that the BIOS has set up at boot time. The remaining values are linearly interpolated. The number of Pstates depends on your fsb frequency and max cpu speed, and can range from 6xFSB to max cpu freq, in steps of 2xFSB.

Also, for those who prefer sysctl interface, a new version 1.5.0 is being tested right now which has a couple more features, among which are a few new sysctl keys: "kern.cputhrottle_usage" which displays the % of time your computer has stayed in each of the frequencies (pstates), "kern.cputhrottle_avgfreq" which shows a weighted average frequency (by amount of time your computer has stayed on it), and "kern.cputhrottle_totalthrottles" which shows how many times the cpu freq was throttled so far. Turning kern.cputhrottle_auto on or off also finally works now. This version will be uploaded in a few days once I've made sure there are no fatal bugs (like with 1.4.5).

Does it work only with the Voodoo Kernel?
I'd rather not disable AppleIntelCPUPM because that will break S3 sleep.

I wonder what processor is that from mercurysquad:
CODE
kern.cputhrottle_freqs: 800 1067 1333 1733
kern.cputhrottle_factoryvolts: 716 780 860 1084
is it a pentium-M or t2370 core2duo? cause if that's a c2d it gives some voltage margin to set.

I would like to change my minimum voltage to 850~900, but can't find much information on other users experiences.

Beerkex'd, wow. wacky results, for now i think this kext will not work with intelcpupowermanagement enabled at all cause it already do the speedsteping on macs.

I just tried the last version 1.4.9 but it stalls a little on bootup it finds just one pstate from ACPI, and on bootup it gives:

WARN IOKit CPUs not found
Auto-throttle could not be started

even when i tried with Pstatetable setted.. so I am sticking with 1.4.0 version for now and turning auto on with a startup item..

kern.cputhrottle_curfreq: 800
kern.cputhrottle_curvolt: 940
kern.cputhrottle_freqs: 800 1067 1333 1600 1867
kern.cputhrottle_factoryvolts: 844 940 988 1036 1116
kern.cputhrottle_ctl: 1551
kern.cputhrottle_auto: 1
kern.cputhrottle_targetload: 30

one question, it wont set 844mv, the minimum voltage it sets is 940mv, is it possible to set less than 940mv?

The last version of IntelEnhancedSpeedStep support Snow to 64 bit?

Thanks
