    I tested with the Cicichen heatsink, it's poor performance way way poorer than the M6800 with bad heatpipes... Waste of 100 USD to be honest. 3 heatpipes full copper, can't handle 150W... Heaven benchmark good temperatures but... On M6800 I get 245FPS and on M6700 I get 170FPS... Furmark seems similar, mostly throttled because of the thermal throttle. Userbenchmark doesn't power throttle. I get 86% on M6800 and on M6700 66%. Both laptops can do 150W max on the MXM slot. I compared the numbers and only one of the benchmark had a bad result, the rest were the same as on M6800. But I don't understand why there's a big FPS gap in Heaven benchmark... The temperature stayed the same for both M6700 and M6800 heatsinks. The 3940XM is way better than the 4940MX in scores, so that's not a CPU issue.

    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?
  13. 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.
  14. 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?
