    Thanks for the great info in this thread. I already wondered why my laptop suddenly dropped in performance while I was playing.


    Now, what I would like to do is to undervolt the Quadro FX 770m.
    I successfully undervolted my desktop 8800GT, but the procedure I used there doesn't seem to work for the laptop graphics card.

    - GPU-Z isn't able to read the BIOS
    - nvflash isn't able to read the BIOS
    - I didn't find any BIOS on the net for the 770m

    Therefore I also cannot edit the BIOS via nibitor or a similar tool, to set new voltages.

    Therefore my question:
    Does anybody know a way to read the BIOS of the Dell Quadro FX?


    Additionally, as this failed, I wanted to work around the downclocking of the GPU by reducing the clockspeed step by step when it reaches critical temperatures (before the "real" hard-coded downclocking occurs), e.g. lower the speed by 50 or 100 MHz.
    Sadly Rivatuner doesn't allow me to access the extended settings that show up below my driver (it only says "Forceware detected").
    I also tried using nTune and the rules there with loading profiles according to temperature and/or CPU load, but that simply didn't work correctly. It always reverted back to my default clocks after some time.

    So, my second question, has anybody successfully used Rivatuner with the 770m, or made nTune work?






    And at last, some testings I have done regarding downclocking:

    Specs:
    Dell Precision M4400
    T9400 @ 2,53GhZ
    nVidia Quadro FX 770M
    BIOS Rev A09


    BIOS A03:
    - no notable downclocking of CPU
    - GPU starts downclocking at 98°C (temp according to GPU-Z)

    BIOS A09 (the one my laptop shipped with) and BIOS A14:
    - downclocking of CPU at 92°C
    - downclocking of GPU at 98°C

    The CPU "upclocks" (sp?) again when it reaches ~88°C
    Tests were done with Furmark and simultanously running Orthos tool.

    I was able to undervolt my CPU via RMClock from 1.250V to 1.000V, which resulted in a drop of maximum CPU temperature from 92° to 74°. Still not what I'm used to from desktop PCs, but a significant reduction.

    Hi,

    Is this still an existing Problem? I think about buying a M4400 with P8800 and the quadro 770m. I run older games (age of empires 2, tackmania) and Catia CAD-Tool. Ist there a heat and noise problem with these programms?

    Thanks
    Christian

    Hey chrissy1988,I have never had temp's as high as some people in this thread,even when I bought an X9100 ES to try,but I did replace my thermal compound on the processor's almost from day one.[over a year now]
    P series cpu's run very cool in this notebook probably as the heatsink's are designed for the 44 and 45w cpu's.
    My usage is Solidwork's [dassault's poor mans Catia ;) ] and most game's,of which,most older stuff doesn't give it too much of a workout,highest GPU temps I see are in the low 80's,which is fine imo.

    Newer bios's are much more relaxed on fan usage [quieter] but run warmer in general use because the fan won't even come on....being a lap user 90% of the time,I stick with earlier bios's for the heat reduction but I do find it annoying when playing a game as the fan is at full speed, compared to one notch down [a lot quieter] with the newer bios's.

    I'm planning to retire my M4400 from game playing and will likely get the upcoming alienware M15X for that,provided it come's with a 16:10 screen,but will definitely keep the M4400 for solidwork's as it has been a model of stability and good performance.
