Pascal is signed with a Hash that changes each time you modify a single bit in the bios. These guys found a way to rebuild the hash that validates the check done by the falcon module on the nvidia core.

Actually I don't know about that, guys like on imac forums modder M0bile found ways to sign pascal vbioses to make them work with their iMacs. They modified the display table definitions, power limits, clocks, etc... iMac 2011 Maxwell and Pascal GPU upgrade | Page 21 | MacRumors Forums They haven't been clear on how they did it, supposedely using this : GitHub - envytools/envytools: Tools for people envious of nvidia's blob driver.

Hi, I tried your method and it worked ! Awesome ! thanks for the tutorial. currently running in 10 bits mod on a quadro M3000M

Saw the pics that's some modding! Rip to that doner motherboard, killed for a 10 cents component ☠️ Tbh, even just a wire shorting out the resistor would have been enough. So 1070 goes in after 980m? And do you have ideas for the cooling mod? You'll prob need to solder more heat pipes + you can add a fan in the ODD bay as you are using the sata port with a very compact msata port, smart.

Great, good to hear the mod was successfull ! Glad I was able to help, enjoy the killer machine ! That's a huge amount of power you have in your ands, how are the temps ? The single fan must be doing a lot of work.

I tested the 1060 MXM but got black screen with backlight on (because of the mod). I had some white static lines that popped up for 1s but the screen was black all of the time. I could hear that the laptop booted into windows, spamming shift played the "sticky keys warning" sound. What I didn't try, and I should have, is testing the p3000 without the mod to see if the DP signal from the gpu on DP_C would be displayed on the internal lcd. It would be complicated to remove my solder prob now, but not impossible, I'll see if I have the time. I'll do some more tests also, like putting 1060 inside the dell 7720 that has eDP on DP_D and seing if the 1060 outputs. I have a 1060 bios with output on D. Looking at the 1060 MXM pcb, THE 3 PNL signals are going somewhere, the tracks are connecting to deep parts of the pcb so we'll see.

Yes it did work, there is no PWM transitor, only a selector that choses between the MXM_PWM and PCH_PWM (pic below) Yes, Zotac 1060 from a en1060 zbox (mini desktop), it has 2 DP and 2 HDMi so they probably used DP_C for HDMi but I'll test soon, I still have the OG vBIOS that was on the card when I got it. Hmmm, yes I know that it's the MXM gpu that sends the 3 pins to the LCD (more correctly to the switcher between MXM and PCH signals that then go to the screen). I wasn't clear ? I know that the mod consists of forcing 3.3v on these pins to make the lcd, it's backlight and it's PWM signal all show 3.3v logic... which forces them on. The lid switch is connected to ENABLET so that closing the lid turns off the screen. Switching the laptop off stops +3VS (where I connected the 3 signal pins) so that also turns off the screen, quite a complete mod honestly ! And yes I didn't want to buy an RTX card, cheapest one is 145 euros for RTX3000 (almost more than zbook 17 g3 + 1060m)

Haha I wasn't going to give up that easy friend ! So I did get it to work ==> eDP screen connected directly to a pascal GPU in the MXM slot ! (but not in the way I planned ... ) So I solder blobed the PNL_PWR_EN + PNL_BL_EN + PNL_BL_PWM (pins 23, 25, 27 on the MXM slot respectively) and connected them to 3.3v. The screen still turns off if I close the lid or put the laptop to sleep, but no suprise the brightness control is stuck at 100% (maybe adding an external arduino or micro controller to send a PWM to control backlight as a fix ??) HOWEVER the 1060M has NO DP ON PORT DP_C, only HDMi !! so with the 1060M in the slot, turning on the laptop gives me 1 second of white lines then black screen. I checked multiple bios and schematics of laptop that use soldered and MXM 1060M. All those that I saw have freaking HDMi on DP_C (pic below of a clevo motherboard, IFPC = DP_C for soldered GPUs) I'm starting to think that the 1060M doesn't have the capabilities for DP on DP_C, the only evidence that I found is that on the MSI GT72VR schematic (pic below) that uses a 1060M MXM, it looks like it should have DP on DP_C. Anyone has a vbios of GT72VR 1060 MXM ? It then gets fed into a SN75DP159 chip that has it's input as HDMI signals so I'm guessing that GT72VR 1060 MXM vbios has dual mode DP on DP_C (?) Anyway I got a for parts precision 7720 with a P3000 MXM gpu (45 euros for the whole laptop what a steal !), looking at it's schematic, the vBIOS of the p3000 should have DP on port C to meet the requirements of the 7720 schematic bloc diagram (pic below). And what do you know, it outputs directly to the eDP screen of the zbook 17 g3 !!! (Finally, I was starting to feel that the zbook 17 g3 was cursed after hours of searching for a DP on DP_C vbios...) So the technique of soldering the 3 PNL_ signals to 3.3v should allow any GPU that has DP (Display port) or eDP output on the same path as the eDP connector for the laptop screen (usually DP_D but for my zbook it's DP_C) will work. Thanks again @SuperMG for pointing me in the right direction. Also, I flashed the p3000 vBIOS on the 1060M with a programmer to see if it would at least display but still nothing.

Yes, That's what I found as well, my g3 has edp on port DP_C of MXM slot. Problem is no vbios for 1060 has edp on C and I can't find a way to mod the bios to change DP outputs. Do you think running standard DP to DP_C with hardware mod could work to drive eDP? What should I look for to do this you think? Thanks

@SuperMG Hi, this is a great mod and could be essential for MXM upgrades !! Where you able to see if a laptop with only DP (display port) output on DP_D would run the eDP screen ? Wouldn't there be issues like screen brigthness adjustments and such ? (heck as long as it outputs a clear picture I wouldn't mind tbh) I would be intrested to try this on my 1060M because it outputs DP on DP_C (that is where my eDP screen is connected on the schematic of my zbook 17 g3) Thanks

Hi, this is a cool mod So these are custom 12v ish motors for the fan ? I might attempt this if all it requires is a small boost circuit, aliexpress has quite a few. I could try bumping it up to 6 or 7 volts, that hopefully won't burn out the fans. My zbook 17 g3 with gtx 1060 has a hard time keeping the gpu cool even when fans are set to the max. Could you maybe open the heatshrink tube that's around the booster circuit ? It's to see if the other wires, TACH and PWM are connected to the board he is using. thanks

Hi, I have a Zbook 17 g3. Not exactly the same motherboard as the Zbook 15. I have a similar issue where I would like to run a GTX1060 MXM off the eDP internal lcd directly (without switchables graphics). When I enable dedicated graphics mode I get a black screen but connecting HDMi to a secondary monitor does make it work. I have a boardview of the Zbook 15 g3 and I assume the display configuration is the same with the 17 g3. I have retraced the signals and this is what I found : Zbook 15 g3 =============== DP_C --> eDP mux (4 lanes) --> eDP conn DP_D --> VGA mux (2 lanes) --> VGA conn DP_B = DP2 (4 lanes) --> TBT_DP_1 mux --> Alpine Ridge (TBT controller) --> HDMI or USB_C_1 or USB_C_2 DP_A = DP1 (4 lanes) --> TBT_DP_1 mux --> Alpine Ridge (TBT controller) --> HDMI or USB_C_1 or USB_C_2 The problem that I think is happening is that the MXM G3 zbooks (maybe G4 too but not sure) use a non standard display arrangement. Normally you would have (basing my self off a dell m6700 schematic here) DP_D --> eDP DP_C --> HDMi or DP DP_B --> HDMi or DP DP_A --> HDMi or DP having DP_A, DP_B or DP_C being fed into the Alpine ridge thunderbolt controller to achieve the thunderbolt port outputs. The HDMi/DP switching is done inside the alpine ridge so if you have HDMi output it should mean that you also have at least one display port being fed into the alpine ridge (if HDMi is fed into the alpine ridge it won't work, alpine ridge only accepts display port input) What we need to do is vbios moding to redifine these display outputs on our MXM gpus ! Still haven't found a way to do this unfortunately

That is shunt modding indeed 😉 What you want is to lower the resistance of the shunt resistor I mentionned. Currently it's at 5 mOhms To do this, you can get another 5 mOhm shunt resistor from another laptop (dead motherboard) and solder it on top of the current one, effectively dividing the resistance of the shunt by 2 You can also order some resistors of other values, like 3 or 4 mOhm and solder them on top of the current one Or you can also go the easy way and solder 2 or 3 strands of copper wire on top of the resistor. And you can also go all YOLO and just put a big blob of soler to bridge the resistor making a diy <1mOhm resistor 😄 Bottom line is you really want to solder something solid on it, don't put liquid metal. Here's an example

Found the schematic So the DC jack and docking connector both have the same resistor that measure current meaning there is just one to short. Here it is : (low res couldn't find a better pic) It's the huge resistor near the battery conn and above the RAM, same side as the CPU.

Hi ! That's some epic modding, respect for keeping that old machine running under load ! What do you mean by that, you made a custom plug ? Is it a plug with resistors ? I think the max charger you can connect to HP workstations is 230W with a 100K resistor between VCC and ID pin. You are bang on the money, what you need to do is find the power input shunt resistor that is used by the power management IC. You need to short it so that it's resistance is lower and the laptop will kick in the overcurrent protection for more than 217w load. Running wires from the main power rail (tapping in on the motherboard and not on the barrel jack conector) to the MXM slot isn't a bad idea, it will take some of the load off of the internal power rails on the motherboard so it won't get as hot. Not sure how two PSU's will help, just run your modified 350W (showing up as a 230w orignal HP ?) through the dockin conn. For the shunt resistor, there might be one that is specific for the docking connector power input. One thing to consider is the docking conn is an array of pins and these might heat up under 10+ AMPS of load. If you feel like it heats up too much, use the barrel connector as it will have lower resistance and thus lower power loss. I'll look up schematics for you HP, they should show which shunt resistor to short out. Good luck !
