Dell Precision M6700 Owners Thread

Most of the time the M6700 is docked and a display is attached to the DVI port so off course the NVIDIA is selected. But also when i start the M6700 undocked the mentioned problem is present. I've disabled the hibernation of Windows 10 so every machine start is from the scratch so it is completely independent from docking influences.

For testing I completely removed the NVIDIA driver via DDU and reinstalled v419.35 without issues. Still the 980m is not completely disabled so the situation persist. Please check hwinfo and check in the sensors window if your M5000M is requiring any wattage and also the clocks of memory and cpu core itself are on the minimum settings instead of 0 like it shloud be. For the M4000M in my Precison 7710 it is like that.

 

The P5000 in my system is pulling aaround 4.5W. (I expected as much, it was in use docked all day.) Not sure what you're asking about the CPU and memory clock speeds? Are you talking about on the GPU? They stay at the minimum level (140 MHz / 200 MHz) and not 0 as you say, and again what I expected, the GPU is not powering off after being docked. I was able to get it to go idle by disabling/enabling the device in Device Manager.

 

Sorry, it was to late last night. I meant GPU clock off course

When running on battery with my Precision 7710 or my Alienware 15 R3 the corresponding discrete graphics cards are completely disabled according to hwinfo (zero power consumption, zero values for gpu clock and vram etc.). In my M6700 this is never the case, even it was not docked before. After a complete new restart of Windows without anything attached to the notebook the power draw of the discrete card should be zero in any case.

But I will test enabling/disabling via device manager this evening - we will see what happens - my guess so far, the 980m will still be active

 

Yes, it appears they "fixed" that in the latest drivers. That's too bad. I wonder what "bug" they were fixing....

 

Yesterday I tested disabling/enabling of the 980M via Device Manager in the following sceanrio:
1. M6700 booting on battery (no externals attached at all): power consumption GPU ~5W
2. Disabled 980m via Device Manager: poor thing power consumption or visibilty of gpu not checked in hwinfo...
3. Enabled 980m via Device Manager: power consumption GPU again ~5W

Thinking about testing 419.67 driver (including INF modding) but will use settings for 980m instead M5000M in NVIDIA inf file first. After that I will try the M5000M settings. At least there is an older NVIDIA driver laying around (I guess 411.*) which I modded and used successfully before for the K2200M installed in my M4800.

 

Hi, I realise today that I have the same problem as you actually, I bought a non working GTX970M 6Gb (msi) with one dead mosfet for 40€ but replaced it with one on my K4000M, after that it work "fine", except that I needed modded inf file in order to have it "working" in the device manager.
So I tried with the 418.81 notebook drivers from nvidia, replaced with my "hardware id" on two different space in the inf file, then my 970m got regonized but nothing run on it, everything run on the intel HD4000 even if the 970m is clocked over 1GHz. I'm running with optimus enabled in the bios.
Maybe the problem is with windows 7 ?
Can someone mod me the inf file for the 419.67 with that information in the picture below? (only the inf file)
Thanks a lot

 

Anyone else having issues with random shutdowns on battery? I have an m6700 with the 120hz 3D screen and a K3000M, if it stays plugged in everything works fine, and even if I unplug it and run on battery it works except the GPU is locked to 135Mhz, (Perfcap idle) I've tried new drivers, older drivers, Nvidia inspector, nothing. This is less important as im waiting on a new GPU anyway (MXM RX 480), what has been annoying me is under CPU load the laptop just shuts off on battery. It's not dependent on battery level either, I've had it shut off at 15%, around 65%, even at 100%, about 10-15 seconds after starting a CPU stress test the laptop just shuts off without warning and I have to reinsert the battery (or plug it in) to boot it again, I don't think its the battery, I replaced it like 3 months ago and the main board was also replaced ~2-3 Months ago (I do have another *mostly* functioning main board that I could swap in to test if that could be the issue. I figured I would test if it was power draw related by stressing the GPU but its stuck at 135Mhz so I have no way of testing it :/ (it didn't shut down under GPU load)

 

The only case mine m6700 shutdown on battery is when both my CPU (3840QM) and GPU (GTX970M) is running.
I'm curious about your M6700, how do you put a 120hz 3d screen on it ?

 

Mine shuts down on battery under CPU load, the GPU is limited to 135Mhz on battery for me for some reason... I think its a bad battery because it won't turn back on until you remove the battery or plug it in. As for the 120hz screen, you need a 3D display cable (it has a sticker that says '3D' on it. I'll link images when I am not on mobile. The panel is a Samsung LTN173HT02.
Edit: on desktop now, here is a picture of what I am talking about, you can find it by googling 'M6700 3D display calbe'
It uses eDP so there will be no optimus (iGPU) with the 3D display.

 

I think that the gpu locked to low frequency is normal on kepler unless you got an unlocked vbios, with my old K4000M I would have 135MHz in load with the stock vbios when on battery and as soon as I flashed a new bios I got the full performance on the K4000M on battery, the cpu was running at 1.2GHz but when I forced it to base clock (without turbo) with throttlestop my m6700 would shutdown as well.
Thanks you, but you got a dell RGB/IPS screen at first ? or you got the LVDS one ? do you try any 4k display ? and do you try with another gpu than the kepler you have ?
I never teardown my display assembly, but appart for the eDP on the board and on the display, what is the use of the two others connectors ?

I really need to unlock the cpu multi/tdp and BCLK as well the undervolt/overvolt (hard)mod on mine before I got the 3920XM
What is the best frequency we can got H24 on XM cpu on this M6700 ?
