    Can you post some picture of the mentioned board you’ve got? I’d really like to the way it’s supposed to be implemented. My way would be to just manually solder the eDP data channels and smBus lines directly to the MXM slot on the PCB. Another way might be to use the dell wireless display port next to the WiFi card(that weird long mPCIe port). The extra pins are for the video signal which is just eDP/HDMI. These signals do either come from the MXM slot or the PCH and are switched Via MUX. This might be the easiest entry point as you could just design a breakout board for the signals. Does anyone know if there are bios or EC limitations that would prevent this to work?

    I’m actually planing on doing this along with connecting the dgpu straight to the mDP connector. In theory it should be possible by adding the eDP and smBus lanes to the mxm slot. Thing is, I don’t know if software modifications are necessary for this to work(bios). There’s also the problem that the DP signal is fragile af. Both wires of each lane needs to have the almost exact same length and impedance

    Interesting, thought this wasn't a thing anymore since often cards have different vBios versions for different amounts of memory. Are there any sources for how to place the resistors for specific memory sizes like for a 980M or 1070M(ex. the MSI version)
  4. DoenerBoy123
    Would be interesting to know what part of the vBios needs to be modded in order to use that amount of memory. Id really like to try something like that on an old GTX 980

    I had the same Issue and also tried that, but this does not seem to fix this(at least in my case). As I mentioned above, you first have to refresh the bios chip with a dump of whatever version. This makes the usb backflash working again which is what your machine brings back to life. I had to desolder the bios chip in order to be recognised by the CH341A programmer, probably because the 3.3V rail draws too much current. My theory is that this Intel HD memory setting bricks the Intel ME portion of the rom which is absolutely necessary for the machine to run. This would explain why the USB backflash method does not work in this case as the ME is responsible for the usb flashing process(as far as I know) @simon h Depending on where you live and if you are willing to, you can sent me your board and I can try to revive it the way it worked for me. Just PM me

    For those who might be interested, I've done something similar to a Zotac GTX 1070, also to increase the available power. There are three unused pads left for a total of 10 MOSFETs. The powerstage for the Vcore circuitry consists out of 5 phases, so at the end you have 2 MOSFETs per phase. The stock config has two phases with 2 MOSFETs and three with 1 MOSFET per phase. I already saw a few cards that had these single MOSFET phases burned up, which is another reason why I did this. All these mods were made on a PCB preheater and with leaded solder to decrease stress on involved components. After that I flashed the vBios from the MSI GT72 to raise the powerlimit from 90W to 115-120W I hope that my text is not too confusing, I'm quite tired ....

    Try Nvcleaninstall. In my opinion this is a little bit easier and you have more control over the driver intsallation like telemetry and stuff like that

    This thread is a little bit old now but I want to to give an update about this mod. It’s already a few months past since I’ve mod this card and so far the results are pretty good. I’ve took the mosfets off of an old half working quadro and a 680m I’ve had laying around. The soldering itself was not a big deal, but requires some experience. The maximum power draw with the prema vbios seems to be around 170 watts. The test was done with furmark for a very short time to see how much this card can pull(this was with a 200mhz oc on the core, voltage untouched). In most games the power consumption goes up to around 140-150 watts max with the temperature settling at 65-70 degrees(M17x R4)
  9. DoenerBoy123
    I can recommend NVCleaninstall. In my opinion, this is easier than modding the driver manually and this gives you more control about telemetry and other stuff.

    In the M18x and many other notebook's the MXM slot is wired directly to the main power rail without any switch in between. Even when the notebook is turned off there is voltage present on the slot. This is also why lot's of notebook's with shorted GPU's will trigger the PSU's short circuit protection when plugging in. My guess would be that there is no switch on the adapter board that disconnects the SSD and it's voltage regulator from the main power rail/MXM slot when turned off. This means the SSD is always on and drawing power. It's the same like an external HDD with it's own PSU turned on but without USB being connected to it

    I think it doesn't really matter which template you choose, at least that's the case with my GTX 1070 mobile. I just took the standard template for the 1070 mobile and it worked fine without even having the same hardware id

    Some people replaced the stock fan with one from the m14x R1 as this fan can push much more air. Unfortunately these fans are hard to get as lots of sellers sell "R1 compatible" fans which is not what you want. The R1 one has similar shaped blades like the gpu fan which is the reason why they are so good.
  13. DoenerBoy123
    As far as I know a copper plate between heatsink and die is actually essential as pascals core has less height. To get back to the main topic, I have some plans to try the modification and if I'm lucky I have some time at the weekend. I'll defenetly post some updates, even unsuccesful ones!
  14. DoenerBoy123
    Okay that might be the difference! Are you able to control all the fans independently or do you control all three at once and does the card work at it's desired speed? I was also thinking about using an Arduino and a temperature probe to build something like a Pam fan controller, but that was before I found the fan to be partially working.
  15. DoenerBoy123
    That's what I thought too. In my case the fan works after some warming up and then without issues(GPU heats up to arround 65-70* in idle, fan turns on after some time, now put some load on the GPU and the fan will continue to spin like with a compatible card). I found out that there's actually another thermal sensor on the pcb which monitors the MXM slot ambient temperature which might be responsible for this behaviour. If you look at the HWmonitors's entry to the EC you see that theres no GPU temperature listed with the zotac card. If you use another card like the 980M theres an entry for the GPU, so the EC "sees" the card. I went through the MXM 3.1 spec sheet and found out that MXM specifies some pre defined adress values for the smBus which is how the EC reads the temperature. I think zotac used some diffrent adress values which might be why the EC is unable to read the temp. The adress can't be changed by a using a different vBios, rather there should be some resistors on the card to set the adress. Maybe here are people with more knowlege about smBus and might wanna help solve the problem? As the card semms to be based on the GeCube one, people with those cards can help? Edit: Here's the spec sheet for MXM 3.1 and the thing about the smBus adresses i meant: https://www.module-store.de/media/pdf/d9/a4/43/MXM_Specification_v31_r10.pdf

    Good to know and somehow sad. I'm gonna try this mod the next days when I may have some time. I think it's actually not that hard. As example, the MUX chip used for the mini DP is a Maxim MAX14998. This chip has two inputs, one coming from the PCH and the other coming from the MXM master slot. The inputs of this chip can be changed by setting the switch pin either high or low. So, if my theory is correct I have to disconnect this pin from the EC and pull it low in order to activate the output coming from the MXM slot(according to the schematics). This goes for all outputs, but these have different switches(same principle as described). I dont know about the 1080. I've heard that these card are hard to handle in dGPU only laptops as the eDP output makes some problems(was never intended to be used). My card seems to have the original zotac vBios and works fine as I'm using optimus. Another problem with these zotac cards is the non working fan control, guess that has something to do with the smBus

    Hello, I recently installed the zotac GTX 1070 (these MXM GPUs out of their zBoxes) in my M18x R2 and so far everthing works fine(besides the strange fan behaviour, but thats another topic). As the lack of LVDS support I have to use the GPU in SG mode, so it's running over the iGPU. When connecting an external monitor I noticed that its also connected just to the iGPU which is bad for me as I want to use a high refreshrate screen. I digged through the schematics of the laptop(easily avialable) and noticed that the video outputs are switched by MUX switches that are controlled by the EC. My question now is: is there any way to switch these chips by software like a bios setting or something else? Otherwise I would just set them manually as these chips just get an high or low signal to change the input.

    I had the same problem. You need to reflash the bios chip with a dump from another machine. After that you have to use the backflash method to get it working again
  19. DoenerBoy123
    Got a little update, it’s working again! it was actually the bios which was the culprit. I removed the SPI Rom chip and flashed a dump from another machine(thanks to the guy from Reddit who send me the dump). After that the backflash was working again(and necessary) and I downgraded back to A03. After lot’s of beeps I finally got a picture and it’s working fine now 😄
  20. DoenerBoy123
    Yes, it’s actually almost the same issue. The only difference is that I had no problems before at all. I changed these setting to get some performance increase as I’m running this thing in SG mode(GTX1070). I’ve done the CMOS reset in 3 different ways: 1. I unplugged the battery and waited some time. 2. I unplugged the battery and shorted the battery pins on the board. 3. I left the battery in place and shorted the clrcmos and reset ME pins on the board. These pins are hidden under the msata cable. These can also be found in the schematic which is easily available in the internet. At this moment I rather think it’s the Intel Management Engine firmware which is corrupted. I believe that as this piece of software is absolutely necessary as this initializes CPU. That’s also why it’s not possible to completely disable this junk. For me this would also explain why the reflash method does not work like in the past. The bad thing about that is that this firmware sits on its own rom on the board, so just taking the bios file and using an external programmer seems impossible without having a dump from that exact rom

    Hello guys I've got a pretty weird problem with my M18x R2. I already searched the web but couldn't find an answer. A few days ago I changed some settings in the bios, if I remember correctly DMVT Pre-Allocated. After saving this setting the notebook refuses to even POST. I get no beep errors or anything. If I press the power button the system turns on, the LEDs turn on and then the system shuts itself off. I already reset the CMOS, the IME, tested different hardware configurations and so on. If I remove all the memory sticks I actually get the memory error code. At this point I'm pretty sure that the bios got corrupted for some reason when I saved these settings. Did anyone had a similar problem and got a solution for this? I repaired lots of notebooks but never had an error like this... EDIT: The Bios installed is the a15 unlocked which worked fine until recently. Overall there were no problems at all indicating different kind of problems. I also tried the backflash method with the A03 Bios but the system refuses to read the USB stick. I've used the same stick as last time I reflashed the Bios.
  22. DoenerBoy123
    Thanks for the info! Have you just add the additional MOSFETs or did you replace all with matched ones?

    Hello guys, I have some questions regarding the GeForce GTX 980M. I'm using this card for 2 almost two years now and it's still impressive how much power this card has, especially if you think about the age. I was first using this card in my M17x R4 until I got a M18x R2 for an outstandingly cheap price. I upgraded the M18x with the 980m from the M17x and everything worked fine. As the cooling is better than the 17 I flashed an unlocked vBios(svl7's bios) to get the full potential out of this card. This was working fine for the last two weeks until yesterday. I played GTA V for two hours. Temperature was fine and the card pulled around 110-120w. Then suddenly the screen went black and the overcurrent protection of the PSU(330W Dell/Delta) took place. After a few minutes of measuring I found the GPU, specifically one of the MOSFETs to be the culprit. I replaced the MOSFET with one I found on a K2100M I had lying around(it's the same part, CSD87350D). The card works perfectly fine again and beside the MOSFET luckily noting else was damaged. Long story short: How much can the power stage withstand with three MOSFETs and does it make sense to add the other three "missing" ones? And how much current can the MXM port of the M18x R2 deliver without being damaged?
  24. DoenerBoy123
    That was what I thought too, but on the other hand the 7970M seems to work fine without modifing the systems bios(works by using a vbios with enduro disabled). I may gonna try diffrent vbios versions. Found one that seems to be compatible with the clevo d9000f which, I guess, shares software parts of the bios as it's from the same era.
  25. DoenerBoy123
    Hello, I have an old Clevo W870CU lying around here for some time now which I got pretty cheap due to a faulty CPU vcore capacitor. I now got my hands on an Alienware M18X r2 with two GTX680M's that I wanna reuse as I upgraded this old boy to a single 980M. I installed the GPU and got the BIOS splash screen and the notebook even booted into Windows. After several seconds I noticed that the indicator lights started to blink while the GPU fan was ramping up to full speed. A few seconds later the notebook shut itself down without warning. I then went into the BIOS and saw that the GPU was recognized as "GPU UNKNOWN". Now my assumption is that the vBios is incompatible and that I need to flash another one(like how it is with MXM in general). Has anyone ever done this upgrade on that notebook and has some experience to share how to get this thing working? GPU Is the Dell GTX680M 2GB
