    Just get a 100% working CMOS battery, set the bios to UEFI and no LEGACY OPROM and there you go. RTX Ada working on eDP 1080p 120Hz. No Optimus, no MUX Switch. If we set to UEFI and LEGACY OPROM enabled, the GPU displays 4-5 blinking on the top left corner of the screen and then... Nothing. No boot, laptop stays on. Now I need to figure out how to disable the LEGACY OPROM. I'll probably disassemble the whole laptop, unplug the eDP LCD and force the boot to HDMI out. Legacy works with HDMI because I tried once and I can disable LEGACY OPROM so I'll obtain the eDP display back. I enabled the legacy oprom to use the shell grub...

    90W no issues. So anything above 100W = issue. Are your VRM/Coils cooled? Thermal pads touching the heatsink? You should try with the RTX 5000 HP variant and see the results. It's a 110W to 115W max TDP card and see if the TDP issue persists or not. HP is better because the GPU has the backlight pins integrated in the circuit board.

    Anything eDP is related to the dGPU unlike the M6800. The M6800 can do iGPU or dGPU in eDP. The M6700 has 40 pins and 4 lines so that's good. Easy 1080p 120Hz and 1440p 120Hz. The M6800 is stuck at 1080p 60Hz.

    I already did that, very hard to remove the soldered joints but was able to get a working battery.

    Me and one guy weren't able to get the RTX 3000 from HP to work with the M17X R4 eDP. In LEGACY and in UEFI. It's a 8 beeps. However with a M6700 eDP, the RTX 3000 from HP works in both LEGACY and in UEFI. Also you have the ADLINK version of the RTX 5000 which means your card lacks the backlight pins.

    MSI afterburner has the same power functionality as the the shell smi one.

    Okay let me try. Everytime I switch the settings, it get resetted maybe because of the CMOS battery, that's why I gave up. Let me switch that.

    Hello, they are impacted by the TDP bug, 40W or fluctuating between max TDP to 40/55W. So it's not worth it since they are limited by the Optimus MUX Switch. I got the M6800 to work with the modern RTX Ada and there was no TDP bugs.

    Did you use the drivers version 525 or 528.24?

    The laptop stays on, no boot, nothing. Before it does some HDD status led blinking and then nothing. So power isn't an issue because the laptop would immediately force shutdown. Memory isn't an issue. Unplugging the CMOS isn't solving the boot issue. The pc boots externally in HDMI out by unplugging the eDP LCD cable, so it's none of these issues...

    Hello. If you don't connect the eDP cable but only external hdmi, same waiting issue?
  12. SuperMG
    No it's not... It doesn't use 100% TDP on the BIOS. This is also wrong. And we're talking about the M6700. Also no other VBIOS are compatible with this GPU.
  13. SuperMG
    No this is wrong. Both are eDP, same connectors. It's eDP on DP_D for both, the same as on the RTX 3000 from HP.

    Hello people. I managed to get the RTX 4080 to work on the M6800 eDP UEFI version. No Haswell TDP bugs, displays on eDP and can do 154W max. The same GPU worked on the Clevo P570WM eDP 120Hz 3D laptop (UEFI, 2012, Ivy bridge) However, I tried to use this GPU (with the backlight mod cable) on the Dell Precision M6700 with the eDP 120Hz screen and... It doesn't work. eDP cable is plugged with the backlight mod and the computer doesn't boot, laptop stays on eDP cable is unplugged with the backlight mod cable computer doesn't boot, laptop stays on HDMI is plugged, eDP cable is unplugged with the backlight mod and the computer boots to the bios (external display) The RTX 4080 has eDP on DP_D. The M6700 has eDP set on DP_D. The M6800 also has eDP on DP_D. So what's the difference between the M6700 and M6800? Why it doesn't work? The RTX 3000 from HP works on both laptops. So the maximum I can do for the M6700 is RTX Turing from HP? Any help?

    Hello. Mine has an issue too. I had the RTX 4080 working on it, I removed it. Then days later I put a P5200 and 980M both didn't even work. GPUs COLD. I tested the GPUs on two different laptops and they work. Funny thing is that the pc boots to Windows without any display (Windows start-up sound), also no DP and HDMI out. So the bios isn't corrupted. I tried to hold the power button for 30s too. I don't know if that's sufficient to reset the CMOS. What should I do? Edit: ok 4080 and P3000 work (eDP and UEFI VBIOS) P5200: not work (eDP non-UEFI VBIOS) 980M: not work (no eDP out and UEFI VBIOS). So it seems like the BIOS checks those, if the results are false then the GPU doesn't get powered, so a black screen with no outputs.

    Will the M6700 DC board be compatible with your cable and screen?
  17. SuperMG
    At least you don't have Intel Optimus with an old mux switch
  18. SuperMG
    Yeah because the drivers are locking the TDP control. You need to obtain some older drivers that allows you to control a laptop GPU TDP. There was a 2023 driver allowing you to unlock the MSI afterburner/Nvidia Inspector TDP control. I forgot its version.

    Even if you do this, the GPU has a Vbios TDP limit. You need to edit your vbios I guess. The shunt resistor is efficient if you want to drop the TDP from let's say 150W to 125W because you can't do Vbios edits. It's risky too. I wouldn't try this. @ssj92tried to do a shunt mod on his laptop for the MXM slot for his AW18 R1 but it didn't work for him. He wanted to fix the weird TDP bug from Haswell LVDS systems. Just try the HP RTX 5000, if no issues, sell your ADLINK or use the ADLINK in a pure-eDP system and see if the issue persists.

    No I didn't. I only did Clevo and Dell. eDP with newer cards could work in full UEFI but I don't know how to get full UEFI to work, that's why the newer RTX Ampère and Ada don't work. I have a M6700 for sale, with LVDS and eDP 120Hz screen. And the custom RTX heatsink
  21. SuperMG
    I got the RTX 4080 in pure-eDP to work on M6800, the only problem is the heatsink for the temps. I don't have any TDP bugs, it's full speed. M6700 can do max RTX 5000 Turing. Everything new won't work on eDP, need to use LVDS for newer cards.... (HDMI out is full performance)

    3060 is massively bottlenecked by Intel Optimus and the old mux switch. 3060 has also the weird 40W TDP bug on Haswell based systems that use Intel Optimus. 3060 works great on pure-eDP
  23. SuperMG
    HP and ADLINK aren't the same company. ADLINK doesn't make and provide MXM cards for them. HP is a blue PCB with a different core offset and a different layout for the VRAM. Just search "HP RTX 5000 MXM" on the internet. Yes these are the power resistors, the same I have on my RTX Ada MXM cards. Also why is the 5000 you bought has a black PCB but the one you got is the green PCB with the ADLINK marking? That's sketchy, even though the same is very identical.
  24. SuperMG
    But the Quadro Pascal such as P5000 and P5200 will work on Dreamcolor. I got the RTX 3000 from HP to work with the Dreamcolor in PEG of the M6700 and the P3000 did display in PEG but ACPI error due to the VBIOS.
  25. SuperMG
    I don't think. No. I wouldn't be able to get the P3000, P5200, RTX 3000 HP to work on this laptop with the 120Hz screen, I got 8 beeps.
