Precision M6700 owner's thread

Looking closely it seems that the cables are from 13’, the shell is from 14’ and the antennas are from 15’!

My M6700 was working perfectly fine with the P4000 and eDP display, I don't remember when I used Optimus. The only thing "needed" is UEFI only, otherwise you need to wait 90sec for the legacy oprom to be skip each boot.

Hello. If you don't connect the eDP cable but only external hdmi, same waiting issue?

Hello
Soo my precision m6700 won't boot anymore. I had 32gb of ram (8gb in each slot), but now it won't boot with ram inserted in slots A and/or C, only B and D slots work. This happened to me once and after reseating CPU all four slots worked fine, but now that didn't work. I tried different CPU, cleaning CPU and ram module sockets, reseating ram modules, putting them in different slots but with no luck. Has anyone experienced this before?

You can put a "standard" eDP display in (like a 16:9 4K panel) but these will take a bit of work to get to "fit", the M6700 was released before the "standard" form factor for these panels had materialized (which Dell started using in Precision 7710). It's possible to fit one in, though. I'm not sure what it takes exactly, but I know that @TheQuentincc had a 4K panel working in the M6700 at one point.

 

The 120 Hz glossy "3D" panel that originally shipped in this system can be fit in without such worries. Sorry, I don't have the model number.

To fit a regular eDP 17.3" you basically have to cut the bottom mounting system from the display, then you need to center/wedge the display at the correct place, it's pretty simple.

I never tried that but I believe so since it's the M6700 bios figuring out what to do with the "new" legacy oprom from the dGPU iirc

Hello.

 

I got the RTX 4080 and 4070 to work in the M6700 in eDP without iGPU. In UEFI with legacy OPROM disabled. 

 

DP and HDMI out are working, it depends in the VBIOS DCB

 

Yes embedded MXM RTX cards display in eDP with my backlight mod v2 cable. It also fixes the issue with the ADLINK, PNY and Aetina Turing cards, where these card don't display anything on the eDP display.
