Need Help: Geforce GTX 1070n Successfully Installed in a G1 Zbook 15 but it's not perfect yet

I'm running the following specs


i7-4700MQ @ 2.4Ghz or 3.4Ghz Turbo(Apparently I can overclock this another 3 or 400Mhz)
16 GB Ram soon to be 32GB
win 10 Anniversary edition
500GB Sata 3 SSD
MXM3.B GTX 1070n with Msi Non-Gsync Bios posted by Stas.b85 (I'd like to try a non gsync vbios from a Dell/Alienware that uses Optimus/Hybrid GFX and the MXM version of the GTX 1070n)

Some things need troubleshooting are listed in order of importance:

-When Hybrid GFX is on(I tried Auto and Enabled) the Intel iGPU displays to the laptop screen and my 1070n card can't see the laptop screen, or output to the screen or render games when the laptop screen is the main screen but the 1070n can output via DP to external screens and handle GPU duties if the external screen is the main screen

-The CPU fan runs at max speed with this MXM in it, I assume it is because the Mobo can't read the temp sensors of the 1070n card and I think I can get around that with a more compatible vBios probably one from a Dell will due if not there are temp sensitive fan regulators I can get off ebay and I already ordered one that will ship straight outta china.




( Way less important)
- if I turn off hybrid gfx the device/model id of the laptop changes from 1909 to 197B which requires the nvidia driver inf to be modified again with the "new" laptop model ID and the driver needs to be reinstalled but gpu never comes back on after the "gpu driver install" flicker and the the system beeps until reboot when it comes back on the driver isn't installed

 

Is your machine having 120Hz Panel ? HybridGFX from the way it sounds, seems to be like an Optimus/MUX implementation, Does this Zbook have HW MUX switch ? To make the machine switch to the dGPU/PEG mode like the older Ivy AW and Haswell PGA AWs and now Pascal BGA AWs.

If you are running with the 1070N with iGPU seems like Intel FDI is working (60Hz) (??). Your screen specification is important...yes you said eDP but still, I'd like to know if it's 120Hz or the 60Hz, iirc HP Zbooks have the eDP to LVDS converters on the mobo like the MSI GT83 VR which has a 60Hz panel but uses internal LVDS to eDP conversion.

As we all know Pascal needs eDP outputs or FDI enabled machines like M17x R4 with 60Hz can pull it off with Optimus/SG mode.

P.S - Would be cool if you can share on how you did (Pictures please, love to see the guts ) the 1070N MXM3.0b upgrade onto a MXM A machine...

 

Mind you I have I have 2 of them, one is stock and a good reference system however this one is dedicated to the 1070n MXM project in both cases so long as Hybrid Gfx is on all video to the laptop screen comes from the iGPU. On my stock system the 3d stuff is rendered by the quadro card even if I'm only using the laptop screen so that should be FDI working as it should

BUT
on my 1070 system the dGPU stands aside and lets the iGPU handle everything except for external monitor connections


Not sure about all the Muxing but if I turn off Hybrid GFX the laptop model device ID changes from 1909 to 197b and the iGPU deactivates and the dGPU takes over but installing the nVidia driver in this mode can only get as far as the "gpu driver install" flicker and then it just stays on a blank black screen beeping with long intervals inbetween

again when Hybrid Gfx is on in bios all video to the laptop screen comes from the iGPU so that should be FDI working as it should so that should be the diff between Muxing and using FDI right?



The screen is that popular 15.6 AOU IPS and it is 60hz

My systems is really jacked up right now right now once it is all neat and tidy I will post a thread called Something like "Bga OEMs Hate Him" and include pictures of the results from all the desoldering, dremeling, drilling and resoldering I did

I forgot that I had read someone got it working that way. Do you recall who it was? I'd love to get there vBios

 

Yeah seems like it..as your screen is 60Hz & Pascal working.

It's a Quadro card, you can't flash that on this GeForce GPU.

I think @triturbo should know more about HP Zbook machines, Nevertheless amazing work +rep bud !!

 

Much Appreciated and thx for the Rep!

@triturbo would you like to weigh in at all on this?

 

What version of windows and what driver are you attempting to mod and install?

 

Im using win 10 pro and the latest version of the mobile driver from nvidia 381.65 in which case it has installed without issue with Hybrid GFX on but it will not fully install when hybrid Gfx is off

 

Guys I fixed it!

I caused the problem by having an incomplete knowledge of nVidia INF modifications basically I used Nulls guid to setup everything and I just used a random Section ID and since his guide doesn't describe what they are for or how to mod them I never bothered to but when I went to rewatch the SoundOfLenses video on getting a 965m to work with his Zbook15 I realized he modified the section042 and added the NVSupportOptimus = 1 after trying just that and failing I looked into it all a great deal more and found that you need all 3 of the following in the section you choose for an nvidia card to work with optimus:

rplacd/optimus.md

Long story short I'm an idiot and the things I didn't know that I didn't know caused the problems I spent hours trying to fix through trial and error smh, total rookie mistake

Now that the proof of concept stage is Over I have to build a proper cooling solution

 

Step by step.. but a HP Zbook with a 1070, that's not gonna be easy to cool..
Can you post pics of the machine ? Thanks !

 

I have pictures but it was in an embarrassingly janky state as I worked on proof of concept(getting drivers and games etc working)

I will post the pictures when I am done

 

Congrats Bro!

 

Thanks!
Your thread was a huge inspiration

 

If you're getting a black screen and device disconnection sound during install and a black screen on reboot you're having the issue a lot of people are having. It's a driver issue. Use the older 378.78 or 378.92 drivers and it should install fine.

 

there is no black screen on reboot the driver install either fails or Windows rolls it back but in any case I'm betting the problem was caused by the section ID I used in the driver inf, i'm working on a custom cooling solution so I can't test it right now but when I'm ready I'm going to try using the section ID of the stock card instead since that was setup in the unmodded nvbli inf

 

pic inside?

 

I'm not done just yet. I had gotten my janky cooling up to version 2.0 but discovered 2 issues 1st was that my interim heatsink design ended up pressing down on my custom fan causing it to grind
AND
The fan stops spinning after it's initial spin up

Between these 2 issues I had to pull the whole thing apart I have since received more parts in the mail and begun modify the replacement fan moving the leads from it's factory 5pin micro blade to 4 pin

Next is a bunch of dremeling hopefully the whole thing is complete by end of weekend

 

Sorry that I'm late (not very frequent lately), glad that you sorted it out and of course - congrats! Good luck with the cooling! How have you wired the fan? I have a scheme where both are linked and rotate at the same speed. I'm yet to try it myself though. And as everyone above - pics or it didn't happen

 

I currently have the fan connected via the removed odd power connector I initially intended to use pwm to manage both fans but the laptop mobo sets the fan to full speed when the 1070 is installed and I can't get the popular laptop fan utility to control the fans on either of my z book 15s

What is this fan scheme you have planned?

lol yeah I'll have to post some pics soon

 

Not even HWInfo controls the fans?

As for the linked fans - basically the second gets only power and ground. Have to check it again.

 

i'll have to try it

 

@Ashtrix @sasuke256 @Mobius 1 @triturbo
Some of the trials and tribulations in photos

The interim design didn't need to fit in the case it just needed to keep the card cool enough during testing

The current phase of this project is my final cooling system which should entirely fit inside the laptop

 

Not according to https://www.hwinfo.com/forum/Thread-IMPORTANT-Fan-Control

wouldn't that make the fan run at full speed?

 

what the actual ****

 

?

It's not pretty but you got to break a few eggs to make an omelet

 

I see, that's unfortunate.

Nope. It (slave fan) would run according to the main (master) fan, given the fan control works properly in first place, which seems is not the case.

I'm with you, but from personal experience I know that it takes some till one arrives at a more eye-pleasing setup, no matter what was/is the task in question.

And I salute you for that - function over form!

The main downside is that the MXM-B takes-up valuable space, so you have to either compromise on the fan size, or on the radiator size, or both if you want a fully self-contained system. Do a shared setup (incorporating the CPU side), this way you'll get closer to the desirable temps, while maintaining the stock look. Overall 15"-not-very-thick machine, what the ZBook 15 is, is on the smallish side for fitting and properly using MXM-B, especially 100W+ one. Anyway, kudos for the enthusiasm and keep it up!

 

I see, I think this scheme would work in a 3 pin pre pwm setup not sure about post pwm, others have also suggested, 2 fans on one header may blow the header

thx!

you aren't lying there my friend, the last setup I tried had the pipes crushing the fan and preventing the top piece that holds keyboard and buttons from being installed.

I'm going to dremel that top piece

I'm considering going shared if things don't work out as planned, I already reordered the stock cooler due to having damaged mine through failed bending attempts

 

Works for M18x-R2 upgraded with 2x980ms - the second GPU fan doesn't spin at all, so @clevo-extreme fixed that. So I dug that pdf and the whole story is somewhere in between. You get the PWM signal from the main fan, power and ground you can get from wherever you want, the tach remains under question. In the M18x-R2's case, there's a header for this fan and they just get the PWM signaling from the main, while keeping the rest (P, G, Tach) connected. Not sure if we get the tach as well how it is going to affect both fans' speed or control.

 

Ok I see, what you mean now this was what I was originally planning on doing until my 1070 caused the mobo to go to set the fan to full speed and stay there. I thought you were suggesting an alternative scheme, my bad.

 

Slow and steady

 

Like lambs to the solder???

 

Ugly, but progress is progress should be done this weekend
