Post subject: nVidia - Vista - 8600GT Go - 2d/3dlow/3d performance settings
Archived from groups: alt>comp>periphs>videocards>nvidia (more info?)

Hello!

I got a laptop with a nVidia 8600GT go running on Vista Ultimate 32-bit.
The Bios settings for the 8600GT include 2d, 3d low and 3d performance
settings which are apparently related to power saving states of the OS.
When I switch between the differen power settings of Vista (high
performance, balance, power saving), the clock speed only changes from 3d
performance to 3d low. It never goes down to the 2d clock speeds. Even if I
turn of aero and run on battery, the GPU clock speed remains on 3d low.

So I wonder now, which are the dependant factors for the selection of GPU
clock speed related to the power saving state. Is there a way "to tell" the
OS when to use which clock speed setting. If I run Vista on battery I would
prefer the lowest clock speed possible (2d).

Thanks in advance!

How are you accessing the BIOS settings for the 8600GT on your laptop? What
laptop? nVidia has a 'PowerMiser' applet for the 8600GT Mobile but this in
not available under Vista. My Dell Inspiron 1520 laptop has the nVidia
8600GT Mobile, but no access to the 8600GT Mobile BIOS is provided.

You could install ATItool - if it works with Vista. You will see three sets
of sliders: One for 2D, one for 3D low power, one for 3D performance, each
set having a gpu core speed slider and a memory speed slider. Set the 3D low
power to match the 2D settings, (you could even lower the 2D / 3D low
settings further and see if you still get adequate 2D & aero performance)
and save that profile. ATItool will allow you to restore those settings on
bootup. I'm guessing that Vista aero sets itself to 3D low power while all
3D games appear to use 3D performance mode.

RivaTuner also has the same feature. One or the other should do the job.

ATItool 0.27b http://downloads.guru3d.com/download.php?det=725#download
RivaTuner 2.05 http://downloads.guru3d.com/download.php?det=163

I tried both applications before. Overclocking/Underclocking works only with
pevious dirver versions but not with the 16x.xx drivers - the clock speeds
are locked when using these drivers.
The only way for me to change the clock speed is throuch changing them in
the VBIOS directly.
I wonder what determins the choice of the clock speed. When I disable aero,
the clock speed remains on 3d low.

My laptop is a ASUS VX2s. I cannot access the VBIOS directly. Actually it is
embedded into the normal BIOS.
I found somebody who helped me editing the VBIOS settings.
But anyway, with RivaTuner or ATITool you can see the settings for the three
clock speed modes. And, at least for me, using drivers before the 16x series
allows me to change the clock speed.

Perhaps there is not a significant difference in power consumption between
2D and 3D low in the laptop card when processing 2D content?

I will try my Dell 1520 with ATItool and post any interesting results. I
selected an 85 Watt-hour battery over the 56 Watt-hour battery and gotten
decent enough battery time for word processing/Internet
browsing/digital-music-on-hard-drive use to not worry about the display
adapter power consumption yet.

Two interesting things about my Dell;

holding the [Fn] key down while turning on the system with the power button
boots into the Dell Diagnostic System (automatic and
manual-with-a-graphical-interface)

the 8600M GT is in a socket (according to nVidia that allows an upgrade for
8xxxM cards.)

Good luck.

The 8600 GT in my Asus VX2S is not upgradeable.
My main purpose is to reduce the heat emission when running the latop in low
power mode to prevent the fan to go on. Currently it stays on its lowest
level which is not noticable when being in a normal environment. Only if it
is completely quiet you can hear it. I only want to know if it ever turns of
if the GPU is cooler (and therefore it should run in 2d mode).

I found a post in a forum that states the nVidia 158.45 driver allows Power
Miser in Vista. It will automatically choose among the three power profiles
(2D low power, 3D low power, 3D full speed) according to 3D content and
AC/battery status for a notebook with the nVidia 8600M GT.

I've found that when the CPU is cool enough that many times the fan runs at
a such a slow speed that I can only hear it by placing my ear against the
exhaust port. The Dell diagnostics will check the fan speed at 90% and
100%, as well as at 0% (fan off.)

I think I found the reason why:

Here is a link to the pdf-file describing on page 8 why I cannot get Vista
to run the lowest GPU clock speed:

The only reason why this was impemented like this could be that nVidia/MS

I have installed ATITool on my Dell 5120 laptop the nVidia 8600M GT (Vista
Home Premium.) ATITool shows the three speed settings in the profiles (2D
low power, 3D low power, 3D performance.) Operation in Vista Home Premium
with Aero, all display effects enabled, MS Media Player and IE7 running,
ATITool shows a GPU clock speed of 170 MHz and a graphics memory clock of
100 MHz (the 2D low setting). When I click on the '3D View' button in the
ATITool Window the GPU clock speed and the graphics memory clock speed
immediately jump to the '3D performance level (475 MHz/400 MHz.) When I
click the '3D View' off, the GPU clock speed and graphics memory clock speed
don't change for 15 - 30 seconds or so and then drop to the 3D low power
setting (275 MHz/ 200 MHz); then after another 15- 30 seconds the GPU clock
speed and graphics speed drop down to the 2D low power setting (175 MHz/100
MHz.) I assume this delay is to prevent the speeds from inconveniently
bopping up and down as short term demand changes.

I conclude that the 8600M GT power saving features work correctly with my
Dell 1520 ( E7300 2.0 GHz 4 MByte L2 cache Core 2 Duo mobile) and Vista Home
Premium (drivers supplied with the system.) You should check with ASUS and
ask that they explain/correct the problem you experience with graphics power
saving, as the three speed settings definitely DO work for my Dell.

(Also, for what it is worth, your 8600M GT probably IS upgradeable as it
would use the same socket as the other nVidia 8x00M cards, and nVidia is the
only producer of the 8x00M series. Whether or not power consumption or heat
production could be handled by your laptop is another question [I don't have
any data on the 8700M cards.])

| Sebastian, have you made any progress with your 8600M GT?
_____

I have used ATITool with my Dell 1520/8600M GT/Vista notebook and found that
all three speed sets are activated when appropriate. (See my earlier post
in this thread.)

Now that the ambient temperature is lower with the approach of Winter here
(Atlanta, ~ 18 C - 7 C) the cooling fan(s) in my Dell 1520 are off at
startup and continue to be off as long as the CPU and GPU temperatures are
low (battery and AC).

When I boot up the 8600M GT speed starts at 475/400 and then settles down to
170/100. When I start the 'Spider Solitaire' game in Vista, the speed jumps
to 475/400 when the cards are dealt, but then settles down to 170/100 while
I move single cards and stacks. Each time a new round of cards is dealt the
speed jumps up again. The same pattern occurs with 'Hearts'. For the
"Chess Titan' game in Vista, the speed stays at 475/400 as long as I play at
the rate of 20 seconds or so per move. The above speed patterns hold
whether the system is on battery or AC.

I have tried overclocking the 8600M GT and had reasonable results. So far I
have tried 550 MHz/475 MHz (vs. 475 MHz/400 MHz stock) and been able to run
3DMark. After a few more runs and attempts at a higher overclock I'll post
the results.

Good luck with your 8600M GT.

I can overclock mine up to 580/500. Which is more on the better side...

Unfortunately my GPU does not clock down to 175/100 (2d settings). I might
have screwed up something but the system runs like a charm right now so I
won't try to install it from the scratch only to see if this resolves the
problem... XD

Thanks for the help anyway!
