    Big thanks for the PB5 Service Manuals.

    Of particular interest is the display output setup in the PB5 with Thunderbolt 3 present.

    There's seemingly 5 outputs from the NV GPU to various ports (HDMI2.0, mini-DP1.4, Thunderbolt3, USB Type-C+DP and EDP->MUX). Granted, most Nvidia GPUs are software limited to 4 display outputs, it appears that if you run it in Optimus mode (so the Intel iGPU runs the internal panel), you could then drive a total of 5 displays from this rig.

    I've not looked over them but often one of those DP signals is shared with say the TB3 or USB port.

    Typically this is the case. They are labelled separately in the Block Diagram at the very least (IFPA, IFPC, IFPD, IFPE and IFPF).

    The DP signal to TB3 uses a DP repeater (link), presumably to keep the signal noise-free when transporting across the motherboard. Interestingly, it's only DP1.2.

    I'm in the process now on waiting for a PB50RF-G so I'll know soon enough ;)

    Also of note, the MUX chip is listed as a ParadeTech PS8331 (haven't seen it listed in previous systems).

    As a note for the models with the 4k OLED it's optimus mode only due to the Nvidia chip not having the right brightness control interface.

    So let's say i decide to run a specific software only with rtx 2070 on a PB51RF-G with 4k oled display.
    (right click on the icon--->"run with graphics processor"--->"High-performance NVIDIA processor).

    Since i can only be on "hybrid mode", the igpu will not only send to the display the frames created by the nvidia gpu but at the same will allow me to increase or lower brightness even if i'm actually using rtx 2070, whose function at this point is only to originate the frames ?

    Yes the 2070 would be a co-processor only with commands sent to it by the IGP.

    I am going to definitely recommend this site for Clevo, there are links not only to service manuals but various useful software as well as BIOS files, notebook specific bios update instructions, and other useful and hard to find things such as these.

    So... Would anyone here have service manuals for the Clevo PC50Dxx series, as well as the X170SM-G laptops? This is the bleeding edge.. even Sager doesn't have these laptops on their support page, and they're selling them.

    Nothing to really download yet, it comes on the machine.

    The only manuals that come with the machines are the Concise User Guide, and the expanded User Guide. In both of those, they mention absolutely nothing about which drive slots are which. The Motherboard doesn't even have legends on them this time, apart from a generic "Sata/NVME/Optane" silkscreen. I'm looking for a Drive 0, Drive 1, Drive 2 specification, if there even is one, since NVME has thrown all sense of order out the window. I have been able to determine that the SATA, non-NVME M.2 is next to the Subwoofer, and no NVME drive is detected there. I am having some interesting issues with a 4TB Raid0 across 2 NVME Samsungs, and an 8TB NVME storage drive. So far, I can swap the RAID0 drives into any of the NVME slots and it works swimmingly, but the moment I plug the 8TB into any slot while in RAID, Windows goes belly up with a kernel_security_check_failure BSOD. I believe this is happening on the Driver verification process on the initial load in of the Kernel.. I don't know why RAID is fouling it though, since it works fine when non-RAID.

    Another issue I have found, (and audio types might want to take note of this) Is that the dedicated Microphone jack has very poor filtering on the power supply for that circuit. The onboard microphones are clear, and the headset microphone is clear, but the Stereo Microphone jack has a terrible DC-DC Bump converter whine being passed to the audio input. I suspect that there are a couple places for capacitors to be placed that would wipe that problem out, the trick is that only the "Service Manual" has the schematics to find out where those pads are. And yes, I use the schematics in troubleshooting, diagnosis and repair of the laptops VERY OFTEN.
