Default FX2800M - driver 260.19.44 - adaptive clocking not working

I run Opensuse 11.3 with KDE 4.5 on a Dell M6500 with a FX2800M video card and an i7 Q 840 processor. Kernel version is 2.6.34.7-0.7-default. More precise (uname -a):
2.6.34.7-0.7-default #1 SMP 2010-12-13 11:13:53 +0100 x86_64 x86_64 x86_64 GNU/Linux.

I installed nvidia's driver 260.19.44. Afterwards I noticed that adaptive clocking is not working.

The graphics card always (!) runs with maximum speed, i.e.:
graphics clock at 600 MHz, memory clock at 1000 MHz, processor clock at 1500 MHz.

The 4 possible performance levels are displayed though. However, an automatic clock frequency reduction does not occur at any time.

This is in strong contrast to a FX 1800M on a Dell M4500. There the graphics card adaptively reduces its clock rates down to the lowest level when no 3d applications or only KDE's 3D effects are running.

I can reduce the clock rates manually via enabling coolbits in xorg.conf and reducing the clock rates by hand in the nvidia settings panel.

However, even settings as
Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x3333;"
in xorg.conf do not trigger an automatic adaptive clocking.

This is true also for beta driver 270.26.

Is this a driver problem or a defect of the graphics cards ?

Hello moenchmeyer,
NVIDIA is trying to repro this issue in house Bug ID: 801575. Need some more info from your side :
- Please attach nvidia-bug-report.log by running `nvidia-bug-report.sh` as root
- Are you facing same issue with GNOME desktop as well ?
- Have you installed KDE 4.5 from distro CD/DVD or externally from suse repository ? If from online suse repository , then let us know the packages path ?

Hello moenchmeyer,

The closest system we were able to find was the M6500 with Quadro 3800M. The system design is the same, but it has a faster GPU. Clocks were working correctly on this system.

These sorts of issues are usually due to ACPI bugs in the SBIOS, kernel, or GPU driver. Could you try updating your SBIOS to the latest available version?

Hello,

attached you find the requested nvidia-bug-report.log. Actually it does not tell much more than the kernel version.
Regarding gnome : I shall install it and provide some information soon.

Regarding your remarks about SBIOS:
What is an SBIOS in comparison to a normal BIOS ? The Bios on the Dell M6500 is Dell's latest namely version A06.

Repository used for KDE 4.5:

http://download.opensuse.org/reposit...openSUSE_11.3/

Installation of the KDE programs was done via Yast.

By the way : I think the problem with adaptive clocking was the same for KDE 4.4 which was orginally installed together with the basic Opensuse 11.3 system.

Attached you find a screenshot of the nvidia settings program.

I meanwhile checked adaptive clocking with Gnome. No difference so far. The grka is running at maximum speed all the time.

I in addition tried the 270.26 Beta driver. No difference either.

Furthermore I tried reducing the clock frequencies manually by using "clock frequencies" in "nvidia settigs" (with the 260.19.44 driver running) and got a total freeze of the X11 system some seconds later when moving a window on the KDE screen. No visible reaction to mouse or key input any more after that. Had to restart the whole system.

Very similar to the instability problems reported at

Sorry for any confusion. The SBIOS is the System BIOS (a.k.a "regular BIOS"), as opposed to the VBIOS, or Video BIOS. We were also testing with System BIOS A06 as well.

I should add that the graphics card reacts when disconnectiong the power cable.

Then it reduces clock speed to performance level 2 - and remains there. It never reduces to performance level 1 or 0.

I.e., when using battery power it runs constantly at
Graphics clock = 383 MHz, Memory Clock = 301 MHz, Proc. Clock = 767 MHz

As soon as the power cable is attached again the graka runs constantly at performance level 3.

I've got the same machine and my dynamic clocking is working under [K]ubuntu 10.10 - but the dynamic clocking is sometimes (= at least 1x a day) freezing my system...

More informations about that are in the thread http://www.nvnews.net/vbulletin/showthread.php?t=160348

Some days ago I tested the behaviour of my card for Windows 7, too. There, I see the same strange behaviour - the card runs at maximum speed all the time. Of course this affects not only battery time but also the thermal behaviour of the M6500.

As "Chris M" sees a reduction of clock frequencies in Ubuntu and Nvidia confirmed a clock frequency reduction for a FX3800M I tend to assume that my card has a defect or that its hardware was somehow hampered/misconfigured by Dell.

Can somebody from Nvidia confirm that a normal FX2800M should reduce its clock frequencies for my kernel and the driver in question ?

By the way: I contacted Dell last week. The Dell tech guys I had some discussions with were really astonished that Nvidia cards reduce their clock frequencies at all. This seemed to be real news for them. No comment ....

Chris, I quickly read through your thread. The interesting thing is that you even have problems when you disable the powermizer in your xorg.conf. A manually disabled powermizer corresponds in some way to my situation where no adaptive clocking is working under whatever conditions.

Therefore, I played around a bit on my M6500. Enabling 3D effects, opening a lot of different applications, firefox, libre office etc.. What I can confirm is that I observed some freezes of X11, too, on my system with Opensuse 11.3 and with the 260.19.44 driver for the FX2800M.

However, I did not see any problems at all whilst working the last 3 days with Opensuse 11.3 and 11.4 on a Dell M90 with an FX1500M and Nividia driver 260.19.29. Strange, isn't it ?

Yes, we normally expect this GPU to be able to switch clocks for power management purposes. When we tried to reproduce your problem we saw that our system changed clocks normally.
