I don't have done a lot of VBIOS flashing, I'm just a passionate electronic engineering student that likes to play around with electronics and IT stuff ?
Today I experimented with changing values of resistors in a "suspicious" array on my Palit P106-100.
Out of 7 of them, 6 of which didn't do nothing, 1 changed the PCI ID from 1C07 (P106-100) to 1C47 (nothing) with no possibilities of chosing intermediate values.
I'll play around more with the PCB in the next days and post updates here.
@UnrealEngine4 a lot of people seem to like the CH341a with SOIC clip for under $10. I myself have an old EZ2010 programmer but that needs the chip de-soldered so I cannot speak for those other ones but sometimes the loading on the programmer when used with the clip may be too much for it to work properly. I think @Falkentyne has a SkyPro or something (maybe I'm thinking of satellite TV lol) so maybe he'll comment. Lots of different programmers out there, even RasberryPi can be used.
In circuit, ie. without de-soldering / removing the chip.
As for signing drivers it's not so hard to self sign but still need testsigning enabled for Windows x64. Otherwise its certificate needs to be chained to a certification authority which last time I looked costs about 400-800 a year. I sometimes write my own crude drivers and don't have that kind of money just to sign a temporary driver so use testsigning all the time and FWIW never have had a problem with it except for one time with some Chinese hackers.. No, I'm only kidding, about the hackers. Besides I'm pretty sure getting a hacked driver from a large and well known Company approved isn't going to happen.
Given that the ass has fallen out of mining lately, maybe nvidia and it's partners should remove the driver restrictions and market these as egpu cards instead? I mean hell, if you wanted a really cheap and effective egpu, aside from the driver fiddling, the P106 is ideal, no money wasted on ports you aren't going to use, or anything
I have to wonder.
The original setup was using the P106 as the main GPU but outputting over the onboard video out.
The attempt to SLI the P106 with a 1060 didn't work out.
BUT, would it be possible to install two P106's with the hacked drivers, then SLI those, while still outputting video over the onboard video out ports?
Because if you could... that's a lot of power for a very small amount of money.
As far as limitations go about using nvidia control panel, you could try throwing a third card in of a different generation (or the same), but only enabling SLI on the P106's, i recall a long time ago having two GTX 580's and a GTX 460, and running the 580's in SLI with the 460 as physx slave, so in rough theory, the third card would be used to bypass the control panels demand for video output, allowing you to go in and setup SLI between the two P106's, then use the original method to run the cards through the onboard video connector.
looking at hi res photos of the back of the PCB of the P106 card, if we look at the lower right hand side does that not appear to be a DVI connector .... looking at a GTX1060 on fleabay it appears almost identical.
the number of pins are identical. a bit of solder wick and some soldering skills .... and a molex type DVI connector ? and output?
We didn’t recommend using the Chinese driver in our mining GPU video, but now, we’ll show you how to make Nvidia’s drivers work for yourself – And how to go deeper.

How to mod the P106 driver
Make sure Secure Boot is disabled and Windows is in testsigning mode
Check your motherboard manual for information on how to disable Secure Boot
Testsigning can be enabled by opening up a Command Prompt or PowerShell as administrator, then typing:
bcdedit /set {current} testsigning on
bcdedit /set {current} nointegritychecks on
This can be done for a single boot by going to Start -> Power -> Restart and holding shift while clicking Restart, then choosing Troubleshoot, then Advanced Options, then Startup Settings - Once you get to the menu, choose to disable driver signature enforcement.
After restarting, you’ll know it worked if some text is displayed in the lower right corner of your desktop
Download and extract the GeForce driver using 7-Zip
In the extracted folder, go to the Display.Driver folder and open nv_dispi.infusing Notepad++
Search for lines containing 1B87 (P104-100), 1BC7, (P104-101) 1C07(P106-100), and 1C09 (P106-090)
Change each line's Section number to match the 1C06 (GTX 1060) line - On 416.34, that means from Section110 to Section108
On the third set of lines, the Section numbers will be different; Again change it to match the 1C06 (GTX 1060) line - On 416.34, that's Section109 to Section107
Save the file
Install the driver as normal – Windows will complain that it’s unsigned; Click allow.
Right-click the desktop, go to Display Settings, then Graphics Settings
From here, you can force any game to use the P106 to render while your integrated GPU is used for display output.
How to perform the SLI mod
Make sure Secure Boot is disabled and Windows is in testsigning mode
Check your motherboard manual for information on how to disable Secure Boot
Testsigning can be enabled by opening up a Command Prompt or PowerShell as administrator, then typing:
bcdedit /set {current} testsigning on
bcdedit /set {current} nointegritychecks on
This can be done for a single boot by going to Start -> Power -> Restart and holding shift while clicking Restart
After restarting, you’ll know it worked if some text is displayed in the lower right corner of your desktop
Install both graphics cards you wish to attempt SLI with
The first three characters of the PCI device ID MUST match to enable SLI
To find out what the device ID is, right-click the start button and click Device Manager
In the Display adaptors list double-click the card you want to check.
Under the Details tab, click the drop-down and then click Hardware IDs.
It will look like this: PCI\VEN_10DE&DEV_1F07&SUBSYS_86701043&REV_A1
VEN_10DE means Nvidia, while DEV_1F07 is the device ID – In this example, an RTX 2070. So in order to run SLI, the other card’s device ID will have to also start with DEV_1F0
Download and install the GeForce driver as usual
Download and extract the DifferentSLIAuto package
Go to C:\Windows\System32\DriverStore\FileRepository and sort by date
Go into the newest folder beginning with nv_dispi.inf
Copy the nvlddmkm.sys file to the DifferentSLIAuto folder
Open the install.cmd file in the DifferentSLIAuto folder in Notepad++
Replace the three mentions of nv_dispi.inf in install.cmd with the folder name we got the nvlddmkm.sys file
Open the nvlddmkm.sys we copied in a hex editor (HxD)
In HxD, go to Search, then Find, then click the Hex Values tab
Search for 79050fba6b240e
Position the cursor at the start of these values
Replace with C7432400000000 (no need to delete first, just type over it)
Save the file
Reboot into Safe Mode with Networking
Click Start, then Power, then hold shift while clicking Reboot
In the menu that comes up, click Troubleshoot, then Advanced Options, then Startup Settings (on some PCs, this may be behind a “show more options” arrow) - Once the PC reboots, press 5 on the screen that appears.
Run install.cmd in the DifferentSLIAuto folder as administrator
Reboot into normal mode
Enable SLI (hopefully)
