Precision M6700 owner's thread

Weird, after installing the M5000M and 3940XM, my machine refuses to even POST if I connect the ribbon left on the palmrest labelled "media".

It goes into some kind of failstate with the CPU fan going to 100% and then the machine reboots.

OK, found out the problem, one of the contact pads in the ribbon was bent backwards, fixed.

Runs like a champ now with the 3940XM / M5000M combo. Installed the latest driver using NVcleaninstall and adding the device ID:

This is with +135MHz on the core clock, can't go any higher in Afterburner. The temps are amazing too, card is running inthe 60*C range under full load.

I repadded it using 1.5mm Arctic thermal pads and also repadded the CPU VRM part and added some thermal putty between the PCH and the heatsink. No idea what they were trying to achieve by having a bare bit of aluminum hanging above the PCH without a thermal pad inbetween.

I've seen it on both of my 6700's already.

 

I was also looking at swapping the screen bezel for a one with the webcam and it looks like there must be some interconnect board in the lid itself as the webcam model doesn't have any extra cables going to the mainboard.

Okay, I reinstalled the OS and now for the love of all that's holy I can't reinstall the driver. Getting a black screen + reboot during install of the modded driver, weird.

Ok, so its quite specific to drivers. I found out that 55x release still works, 57x causes a crash and reboot.

Not sure if it's just me but M5000M doesn't support Optimus??

It definitely does, I used it for years in my M6700.

I had issues with it not working when I first put the card in and it was because the driver INF mod was done wrong. I have notes about doing the mod manually (properly) over here — https://www.nbrchive.net/forum.notebookreview.com/threads/precision-7530-precision-7730-owners-thread.820539/page-253.html#post-10937563

You have to pay attention to different subsystem ID depending on whether Optimus is enabled or disabled in the system. If the driver is installed off of the wrong one then the flags for Optimus will not get set and it will not work.

(I would assume that NVcleanstall can handle this, but I never used that.)
