Powermizer


Dunx

Recommended Posts

I seem to be having a problem with Powermizer. Basically I want maximum performance when on AC and max battery life when running on the battery. With the default Dell driver for my Inspiron 9400 with Geforce Go 7800 (78.59) everything works fine.

However when I try using any of the newer drivers (tried 83.40 and 83.91) with the modded .inf file the Powermizer software doesn't update the power setting i.e if I am running on AC then pull the power and run on battery it still thinks I'm running on AC.

I'm guessing that somwhere in the modded .inf there is a software switch that needs changing. Any help would be apreciated.

I searched around and couldn't find info on exactly what you wanted, but Teraphy (I think) did say this.

Virtually any power change will drop your GPU speed to "Max Power Savings" which is very slow, and will lock it there until you reboot. To work around it, you need to add or modify the following four lines in the [nv_SoftwareDeviceSettings] section of your inf:

HKR,, PowerMizerDefault, %REG_DWORD%, 1
HKR,, PowerMizerEnable, %REG_DWORD%, 0
HKR,, PowerMizerLevel, %REG_BINARY%, 01,00,00,00
HKR,, PowerMizerLevelAC, %REG_BINARY%, 01,00,00,00

This will disable PowerMizer and set your GPU to max performance.

You could try using this right here instead.

HKR,, PowerMizerLevel, %REG_BINARY%, 00,00,00,00
HKR,, PowerMizerLevelAC, %REG_BINARY%, 01,00,00,00

I assume the first PowerMizerLevel is for the battery, I am just guessing 0 is max battery though.

Someone else will need to confirm this.

I am betting it is a driver problem and not an INF problem, unless it works fine using a Dell INF.

You could try one of the more recent Dell drivers.

Look for one that says Dell in the title.

If it is a laptop Dell driver it has a Dell laptop INF that might have your card inside, along with Dell only settings.

If a Dell INF works and Pieter's doesn't should be narrowed down to around 10 or so HRK tweaks, which you test yourself or just copy some/most/all of them into Pieter's mod INF before you use it.

Thanks for the advice. I've tried everything you've suggested and been throught the .inf and changed a few things that sounded like they may make a difference. Still no joy though.

I guess that it must be a driver issue as you thought. There is a stange thing though, smartdimmer does detect the change in power source???? Stange that smartdimmer detects the change and powermizer does not?

Everything else with the new drivers and the modded .inf work OK. It's just powermizer that has a problem.

Same details posted logged in this time, so I can track it. doh!

Just one other thing, the Dell nVidia driver does work perfectly. I have posted the .inf settings as an attachment. If anyone has time to look though it and make suggestions on what make the difference between this and one of the modded .inf files from this site I would be grateful.

Hello,

i've got the same problems. I have installed the 84.20-driver with the standard-inf from this site but when I change the powermizer-settings this doesn't influence the temperature of my gpu.

Everything works fine with the original dell-driver but it's much slower than the newer nvidia-versions.

Has anyone an idea to fix this problem?

Any news on this yet?

I've just installed the 84.25 driver to resolve my screenflicker issues (It seems to help!).

But now I'm also experiencing the same problems as the people here.

Powermize does not detect when switching from AC to battery mode.

I'm currently working around this by manually selecting the battery saving mode when I'm on battery.

However, I don't like this solution. Hope a fix will be there soon.

It looks like only the drivers that were meant to be used with laptop GPU support PowerMizer.

i recommend v82.12 for 6200 because it is more stable and there is no problem with powermizer. Powermize detect when switching from AC to battery mode. Also no stand by problem such as 84.xx. i have packard bell R9220 with gforce 6200(manufactured by nec - bios 5.44.02.31.AA)

I have also heard some nice things from the 91 series, try 91.31 too.

Powermizer will only detect ac/battery when the Nvidia driver service is started.

The modded INF's leave it disabled by default due to an issue with that service crashing during shutdown.

Go to control panel, Administrative Tools, Services and look for Nvidia Display Driver Service. Right-click, choose Properties, and change startup type from 'Disabled' to 'Manual', then click OK. Right click the service again and choose Start.

Check your powermizer panel again and see if pulling the AC switches it to battery now.

With the service running you may get an annoying Application Error on nvsvc32.exe when you shut down the notebook.

My workaround is simply not to use shutdown.. i always sleep or hibernate anyway, and both those proceed without issue.

I've been fiddling with this all afternoon.. even tried mixing the nvsvc32.exe from my original, older, 78.11 dell driver (which works) into later driver releases from here.. no dice.. with nvsvc32.exe running, powermizer works but application error on shutdown. It simply cannot by 'stopped' by the service manager on these later drivers without a messy exit.. I don't know if it's a driver issue or an INF issue. It doesn't seem to be an issue with the service alone because, like I said, I tried the service from a known good release with a later set of drivers with the same result. This only affects notebooks as far as I know.

In addition to the problem with shutdown, I also found that my Laptop would not hibernate running anything but the Dell drivers. It just blank screened and doesn't do anything else. Had to power off manually (keep the power button pressed for 4 seconds) to get out of it.

Actually, looks like nVidia have added mobile GPU support to their latest drivers. Downloaded the 84.69 drivers and they work perfectly.
