Yes. Mobile drivers have extra registry keys that disable that, but proprietary/unique mGPU solutions on notebooks don't (like Lenovo's GT650M SLI and GT755M SLI notebooks) and desktop drivers don't either.

Physically yes. BIOS-wise, not yet.

You need to use an external screen to use 3D vision with an external kit. nVidia are money hungry.

I think the current systems need a very drawn-out process to switch from XTU. Clevo's fault.

Try using throttlestop alone to fiddle and setting current limit to 256A (I've seen some notebooks have 255A as highest; this may work too). Your CPU is throttling pretty hard though... it says 4GHz but that score should be closer to 3.4

If you could create a utility to adjust fans and the keyboard backlight feature while we did not have Hotkey software installed, you'd be doing all current-gen clevo notebook owners a ridiculous favour.

There is no publicly available mod for the P750DM2-G. I don't understand why you flashed a P750ZM BIOS mod to it. Even the P750DM-G BIOS would not work.

Not with Prema mod & vBIOS.

Use DDU to clean and shut down for your nVidia drivers, then install the card, then boot up and install drivers fresh. That's the best way. Otherwise, that's basically all you need to do it, as far as I know.

If it will help, I can definitely try. I don't know if I have the correct tool to bake it, though. Does it need to be artifacting in all games? So far it's only been one or two. The other issues (99% util at ~60% of the other card, random split-second freezes once every couple hours, etc) are universally persistent though.

Yup, that's it. Suggest prema mod on the GPU too after you install it but stock vBIOS should work.

@Khenglish any thoughts? This is what the dead 780M looks like I scrutinized them as best I could, but as far as I can see, the working former slave 780M and the barely-working former primary 780M looked exactly the same on all the VRMs, the core, the back, etc. If I didn't have different thermal pastes on the primary and secondary and you swapped them around while I was away from the system I wouldn't be able to tell them apart (except that ID tag near the core, of course). Anything I could try? And/or would you want to buy the dying 780M off of me?

You will likely need a Prema mod. 180W and 980M should be generally sufficient if at stock and undervolting the processor, I think. The only issue would be whether your cooling can handle it, but I think it should be ok.

Okay, so card swap was a success. Primary card now in the slave slot displaying the same features. Less heavy artifacting with SLI on, none with SLI disabled. Confirmed card is near dead, down to single 780M.

Oh yeah, for certain I will.

Will try swapping the GPUs tomorrow. It seems up until about 50% load on the primary card it's fine, and beyond that it has problems. Hopefully on single GPU the slave card will work fine as the primary.

Any advice on restoring proper functioning life to my poor poor workhorse? It's artifacting in some games, has random single-second stutters/not-smooth in others, and just performing extremely sub-par in others. Also, I cannot use NVENC to record anything (though CPU-based recording works). Slave card seems to have no issues (I think, anyway... not sure) so if worse comes to worst I can still run single GPU for a while by swapping the cards, but I'm still going to be down a card and single GPU gets extremely hot for me here. I have used DDU clean & restart and installed drivers fresh and still has problems (before I even enabled SLI) so I know it's the primary card. Any black magic, voodoo, or any other thing I can use? Or maybe someone has a dusty old 780M laying around I can source for somewhat cheap? Or do I just sell this (single GPU, with second GPU cheap for parts) and go on the prowl for a new system entirely? Here's an example of the artifacting in one game. Watch the flickering lights all over:

Ah. Makes sense I guess. Maybe it's all about the models. I know the SM & SM-A series could undervolt (at least with prema mod). I know the ZM/DM can as well. Didn't know the P6xxSx couldn't. Can the P6xxRx I wonder?

Just run DDU and use 372.54 drivers. Should be fine. Also, ugh, W10. Hate that thing.

You can undervolt CPU in BIOS though. My model can too; I just don't because sometimes it resets.

That's pretty great! Let us know if you ever manage T1 instead of T2 =D

Did you use both the system and video BIOS mods?

BE ENTHUSIAST. GET 230W BRICK FROM P670RS. PUSH TO LIMIT WITHOUT BREAKING SYSTEM. OVARCLOOK. BWAHAHAHAHA ETC.

I doubt. 188W from the wall would have to be around 96% efficiency for you to actually be hitting a direct limit. It's possible but I don't think so; I suspect you should be able to at least burst-pull 200W from the wall. You could always consider using the 230W brick that's on the pascal P6xxRx models as an upgrade, though. Should have the same connector.

Yeah, just try reinstalling windows. And make sure you get logs of all of this if your company won't recompense you for it.
