Windows will use the Intel graphics until you boot up a game, I don't think you can get around this as the 1070 needs the Intel graphics to run. If you force the 1070 to run for everything then you are basically running the system in PEG mode, which it cannot do with the 1070. If you find that you are getting really bad performance when you try to run a game then you are getting the weird power throttling issue that most (or all) of us had with the 1070. You can reboot into the BIOS and switch to iGFX mode, then reboot back into the BIOS to select SG mode again. This usually gets the card running properly. You may find that you have to do this every time you turn the laptop on to play a game. It's annoying but it only takes a minute or so.

Have you tried booting with the HDD/SSD and dedicated GPU removed?

So there is no need to use SG mode in the R1 or R2 these days if you have a compatible card in the primary slot? Unless you want to use an NVMe adapter of course.

The 460M was released with the R3 so you will have to run a modded Nvidia driver to get that card to work. AMD cards don't have this issue so they are much more PnP than Nvidia. Since you already have the ATI card, the heatsink bracket you already have should work fine with the 8970M. If you switch to Nvidia you will have to find the Nvidia bracket for the R1/R2. From memory, the standoffs are shorter than those for the R3/R4 and later.

Great job and thanks! I'm sure he will understand.

Hopefully @ssj92 can assist you with this. You seem to have got further than other people with the 10 series cards so I wish you luck getting it working properly.

The 675M will work but it's not plug and play. You will require a modified Nvidia driver to get the card to work. It's not overly difficult and there are plenty of guides out here on how to do it.

Lot's of people have tried bypassing the UEFI issue but unfortunately with no success so far. The 880M's are the best Nvidia cards. The AMD R9 M290x is also an option and doesn't require modifying the display driver like the Nvidia cards.

Awesome! I'm glad another board has been resurrected! If only Dell released the information on how to fix this issue 15 years ago!

I just used an old 4-pin fan cable so you should be good with anything that matches up.

I have never worked on an R1 before, I have one but the board is dead. I've worked on a few R2's though. I was under the impression that the 600M series worked in the R1 but I'd have to do some research before I'm sure. The old NBR archive is available and it will have plenty of information that can help you.

That's what I found as well. I know it works in a Dell M6800 as I guy here on eBay was selling them with the Tesla. He wouldn't tell me how he got the card to work though.

I tried an m6 in one of my 60hz Rangers and it wasn't detected no matter what I tried. Maybe I just got a defective card though.

Yes I believe that is the port but it's been a while since I did it. Yes, the wiring is exactly the same as for the M15x. If you follow the wiring guide you shouldn't have an issue. I have done this fix on the M15x and M17x R1/R2. Let me know if you have any issues when you get to try it.

Yeah, it usually always costs way more to refurbish these old laptops than you think it will. Once you have to start replacing GPUs, the costs can really add up. It's more for the fun of it though, like you say. Keep in mind that these laptops will usually not boot if everything isn't hooked up properly, including the keyboard. It was a weird design idea which they scrapped from the R3 onwards. You'd think that the system was completely dead until you realised that the keyboard ribbon cable wasn't seated properly. Good luck with the refurb!
