    They do not, that was the case on 8570 and 8770 G5 and G6 (probably G4 too) have eDP on DP_D position of MXM slot, G1, G2 and G3 have eDP on DP_C so either a custom vbios is required to get picture on screen or a backlight cable mod. All zbooks have only eDP display connections. 17 g1 and 17 g2 have an eDP to LVDS converter on the display cable because they used LVDS displays, the GPU will read the display as eDP however.

    The RTX 5000 MXM from HP has different mounting holes for the heatstink + screw standoffs to attach the card to the motherboard, this is compared to the standard MXM cards. If you want to fit a P5200 in the 17 G6 you will need the heatsink from the 17 G5, and vice versa if you want the RTX 5000 in the 17 G5. You will also have to grind down the screw standoffs on the 17 G6 motherboard and either : - stick some thick rubber pad and screw the card down on that. - stick some thick thermal pad so that the card "sticks" to the motherboard via the pad + cools down a little bit (especially the extra VRAM chips on the bottom of the card) Hope this helps !

    Yes, you can use linux to flash the stock ES vbios. Overclocked ES vbios requires a hardware flasher. External keyboard is recommended yes.

    https://github.com/JadeRover/Nvidia-vBIOS-Clock-Power-Tweaker/releases It is pretty self explanatory, if you have any questions don't hesitate. you need CH341a bios programmer with 1.8v add-on module ! Also I recommend you half assemble the laptop (leave the keyboard + keyboard deck removed) to have easy access to the MXM gpu during flashing and testing, making sure the custom vbios works before assembling the laptop entirely.

    Yes this one will work, it had eDP on port DP_D. So in the dell bios -> Video, chosing switchable graphics enable or not will result with you getting an image on the internal display. With switchable graphics OFF you will get an FPS boost. Also feel free to overclock the engineering vbios with my utility, I can guide you through the procedure 😉

    Seing as your charger shut's off immediately, it is safe to assume that the main power rail (+19v) of your MXM gpu is shorted. The charger supplies the MXM slot directly, making it cut out with GPU installed = the MXM card is main power rail shorted. This is either due to a capacitor that shorted itself or a high side mosfet short, the high side mosdfet are driving a secondary power rail (+VCC_CORE, +VCC_VRAM, +VCC_PEX, +VCC_1.8v) Best case is a capactitor as it can't damage anything else, mosfet is more problematic as the secondary power rails I mentionned are all at <2v and they suddenly received +19v for a few milliseconds, this is enough to internally destroy the core or the vram chips. I would highly recommend you get a multimeter, even at your local hardware store it will be less than <10$ and very useful for future projects/life. With the multimeter you can trace down the short and then you will need a controlled power source, such as a lab bench PSU to inject a small voltage of 1v @ 2-3 Amps so that the shorted components warms up. Then the component must be replaced (this is more complicated) You can also go to a repair shop and tell them you think it is main power rail short because of charger cutting out immediately, if they do actual motherboard level repairs (not a given) they should be able to confirm it and tell you if the card is fixable.

    Hello, Sorry I am a bit busy with stuff that is not CPR lately. Can you send me your vbios ? I can have a look in the program + with HEX editor to understand what is going on.

    That's just the MXM standard of 10A, they copied it from their reference sheet probably. These arae the ones with the external power connector ? The connector is the same as the one in the XM and KM ? Yes I would agree with this, the simplest way to find out is to use a multimeter and touch one of the big pads while the computer is on, there isn't much risk as the pads are big and an accidental short to ground is unlikely. If this is the case, that it is not connected, the fix would be to solder a wire from the main power rail (19v when the charger is plugged in, 12v when the battery is), the other voltages, 5 volts and 3.3v are probably connected as they don't have an "NC" marker.

    Hello, I need to test that out, I still haven't figured out what inside the vbios is responsible for the boost to 1911Mhz vs 1708Mhz
  11. JadeRover
    This stock HP VR backpack bios worked to make the card post and get the core to 1911Mhz, I am trying to reverse engineer it to find where the 1911M hz limit is VS the 1708Mhz limit in the dell vbios. P5200_HP_ZVRG1.bin
  12. JadeRover
    Yes I though of that as well, I am also thinking of looking into the voltage table that should exist? I found some info of it for Pascal on the internet, that might be a way to unlock clocks or undervolting for these cards.
  13. JadeRover
    OK, so you set 4004mhz on vram and that allowed the card to oc the ram? I've done more testing on the downclocking of the card and I noticed that setting lower clocks just on the core clock list results in downclock + only downclocking on the limit clocks found in the vp profiles also results in downclock (both are independent). So that means that card reads both core clock list + vp profiles to set it's clock value. On my p4000 if I left the limit clock untouched and OC core clocks in the clock list, card would not OC, I also had to raise vp profile limits clocks. My program does both but it appears that this isn't enough for p5200, there must be another hidden "max" limit clock value, in our case 1708mhz. Now I will attempt to replace the p5200 vp section with the sections of GTX cards and p4000 to see if that resolves the issue. EDIT : Well I am starting to fear that the 1708Mhz is baked in deeper into the vbios or the driver as even when using a GTX Virtual P state table or parts of VP table of the MSI P5200 vbios I still hit the 1708Mhz wall... I still have some hope as I am pretty sure the MSI vbios does make the card boost to 1911Mhz (userbenchmark scores) as well as the HP zvr backpack vbios. + Some guy in china managed to boost the P3200 & P4200 to 1900Mhz & 9Ghz vram : P3200 : Search & P4200 : Search The MSI vbios flat out refuses to boot on my system. Pasting parts from the performance section into the working "dell" vbios results in no boot as well

    I've done some testing on my P5200, my utility can downclock the core no problem + GPU-z shows the correct base and boost clocks of my utility, so it is editing the correct core clock values.
  15. JadeRover
    Can you post the vbios that works with the 8ghz OC and the one that doesn't ? What vbios did you use as a base to test these OCs ? I can take a look at the differences
  16. JadeRover
    I experienced something similar with my p4000: Base memory was 6ghz. If I put any value >6ghz it would lock to 7ghz. And then it only applied 9ghz (4504mhz in my tool). Thus it appears quadros skip the 2nd memory oc? On my p4000 : 6ghz -> 7ghz -> 8ghz (skipped) ->9ghz On the p5200 : 7.2ghz -> 8ghz -> 9ghz (skipped) -> 10ghz (maybe)? You can try 10ghz if you are feeling lucky 😉 Also you said modifying core clocks ruins the memory oc? I'll get moving on shucking my p5200 and testing on it
