Dell Precision M6700 Owners Thread

980M does not require a physical mod in this system. You might have to adjust the thermal pad positions slightly because of the extra VRM that was added compared to Kepler cards.
I don't know what the power use is. I don't think it matters that much. If you are gaming on battery power, the system is capped at 100W power draw total and that always causes the GPU to throttle down. For light work, Optimus is engaged and the GPU power draw will be minimal.

 

And 20 bucks worth the 30-40% gain performance? And with the 240w is enough or should I get the 330w if I am planning serious gaming ie Battlefield V and future Doom Eternal and all those crazy games incoming? Mine game with the i7 3740qm so I guess with 16gb should be more than enough for gaming

 

330W won't do you any good. It will work, but it will not increase the power available to the system. (We checked this out when playing with Pascal cards in the M6700/M6800. There is an internal limitation of some sort that prevents additional power from being used.) Doesn't really matter, though, you can fully load the CPU and a GeForce 980M on the 240W PSU. It is only the Pascal GPUs that start pushing this too hard, causing the CPU to be clocked down if the load on the GPU is too high.

 

Pascal as far I have seen here needs a special lcd right? But why then 1060 and beyond don’t work? And they are on fair price on eBay.

The only part that makes me think is that the seller list the 980m just like that so I don’t know if it’s a Clevo or MSI one, whereas the 970m is from an Alienware and it should be plug and play.

And the maxwell line install drivers right away or it needs mod the drivers?

 

Pascal doesn't require any special lcd (only on the premiercolor lcd the brightness is not working -> 100% all the time), you need to have a pascal card and to flash a compatible vbios with the M6700, and as far as I know only the Quadro P4000 and P5000 are supported by the M6700
For your 980M there is different version of mxm, you need to get a 82x105mm mxm 3.0B card


Maxwell is very easy to run on the M6700, nearly all card are compatible, you might need to flash a non-HP vbios if you get a HP card then you need to modify the inf file which is very easy when you get it

 

Well I will pull the trigger for the 980m p series are way out of my budget lol May be in a few years It will be cheaper but 900+ dollars I would get the new Precision line with Xeon lol.

Is that Clevo or MSI? for tech details is it the revision with directx 12 instead directx 11 fl 12?

And it is plug and play right?

 

Clevo or MSI 980M should both work fine. They will all work the same. It is mostly plug and play. You might have to swap the "X bracket" piece on the bottom if the screw size doesn't match up with your heatsink. You can take the bracket off of your K4100M. It is glued on and will require heating up before it can be removed. Otherwise you just drop it in, mod the INF, and good to go.

Quadro P4000 and P5000 work in M6700 but only with modified vBIOS. (And you can't use the M6700 to flash the vBIOS because nothing will boot; you have to do that with a different system or dedicated hardware flasher.) Technically other cards may work but a workable vBIOS would have to be found. I had a P5000 in my M6700 for a while but I had to get rid of it, something was causing it to BSOD periodically (infrequently, once every week or two). Some other people have reported stable systems, though.

These cards are the same as GeForce 980M spec-wise, that would be cheaper if you don't need the pro features that they have.

 

That copper on the pic that is covering ... it’s normal or not? K4100m I have just have the normal x bracket instead that copper, if you know what I mean.

M series of Quadro are damn expensive when you can get the same performance on gtx 9xx too bad they are not as the Kepler series on price range as the 7xx and 8xx

 

The copper is not normal. It appears to be (part of?) a heatsink, and easily removed if you just take out the screws?

 

Yes it seems screws can be removed, do you know or have any clue what’s going on those gtx on aliexpress? I have seen gtx 970m cheaper than eBay, but then I remember the famous cheap lga 2011 motherboards from China...
