Hello!
I want to ask for help in understanding the problem. I have an MSI GT70 (4.gen) laptop with which I want to use a desktop graphics card using an mxm adapter. I give link pictures.


2022-02-14-1887.jpg


Separately, everything works well. The vga was tested, flawless. (rtx 2080)
With a Gigabyte geforce 970 desktop graphics card, this laptop and adapter pair worked flawlessly. The RTX 2080 is not good.
The driver goes up, installs, but the GPU-Z is incomplete, dedicated vga is not present. I tried other vbios versions ..... in vain, same bug. External display works in hdmi mode, but no vga menu, all basic.
I have an open bios for my laptop with lots of setup options. Is there anything I can do to prevent vga from being disabled? VRAM? Something setting like magic.

I do not know what to do. Is there any hope or should I not force this?
DDU doesn't help.
Error code 43 in Device Manager after installation.

You should not use those anti-static bags to sit live electronics on. Many are designed to keep static "OUT" of the bag by conducting electricity around the outside of the bag. In other words, the exterior layers are often conductive, not insulating by design.

Instead, use a hard, flat surface like a wood cutting/bread board, or plain brown cardboard.

Laptops should not be used on beds either. A hard flat surface allow air in the bottom vents.

Sorry, but I am not following. You say "separately", everything works well, flawless and I am assuming you meant the RTX2080 too. How did you test the RTX 2080 "separately"?

And then in the next sentence, you say the 2080 is not good.

I don’t use anything on a bed, it’s just a photo of the hardware. It is set up on every table, put together. Unfortunately I translate, my English is very bad, but I try to put it clearly.
The vga was tested separately and had no problem with it. It was tested by a professional mechanic. A friend of mine also tested it under linux, vga was also there. True, the graphic test gave only a 50% result based on a "Superposition" score. I think it gave a score of up to 90 - 100W after consumption. It was weird, but it was present, it worked, it was VRAM. My laptop can't bring up the graphics hardware.
Something is wrong no matter what I do ..... there was a driver modification, although it is not necessary here. I'm hoping there may be some motherboard bios command that can help.
I can't contact the Chinese master man.
Everything was tested separately, both the adapter and the vga. The laptop is also flawless. There was a Chinese link that was deleted unfortunately. The inventor's side.

The warning about the anti static bags is that they conduct electricity on the outside - its how they work.

With a GPU and nothing connected? You're probably fine.
Anything with power, even a battery? Not worth the risk. As an easy example you could short the back of the CMOS reset pins and have to redo BIOS settings on a motherboard, or you could trip a safety fuse with a laptop if you short out the power somehow

I understand that and thank you for the warning. The trouble is that I don't understand why the rtx 2080 vga adapter, which was purchased recently, doesn't work.
The photos above include 2 photos from a professional laptop specialist. I tested the adapter and converter with him. It was good. One gtx 970 and one rtx 2080 super were tried.
The gtx 970 vga was good. The rtx 2080 super wasn't good, but it was a semi-faulty vga. He died later. At the moment my vga adapter is flawless just not going with the laptop.
My friend says it is not EFI compatible. I think that's stupid. The vga works in a desktop machine. (Linux test .... photos) Then later I took it to another professional workshop to test it. There I already had my own vga adapter exam. This rtx 2080 was tested. He was flawless, according to the master. Tested under Win10. There was also a VRAM test.

It's like the vga is wrong, but I know it's not. Good in a desktop machine.
Only my laptop doesn't carry it.
I have 2 identical MSI laptops. It produces the same thing for both.

With HDMI connection. There is and there is no. I made a new system in vain. Something is disabled.
There is a fantastic bios in the laptop.
Many settings are available from there.
Can't this help?
I thought before I give up, I'll try here. I would have gone to the "notebookreview" page, but it was closed. Maybe it's because of people like me. :-((((((

I've never dealt with external GPU's on laptops, so i'm not the right person to answer these questions - i'd say test the PCI-E riser from a desktop PC and confirm the rise and power setup is functional.

MR007RM just an idea. Remove the battery,go to Device Manager,expand Batteries and disable "Microsoft ACPI-Compliant Control Method Battery".
Next,DDU and reinstall the driver. If it doesn't work i would advise you to continue your troubleshooting in the proper forum: https://egpu.io/forums/.
Good luck.

Okay, I understand now. Thanks for clarifying.

Right! Going by the picture, I was afraid you were applying power while the card was sitting on the anti-static bag. Because the outer layer of those bags are designed to conduct electricity, power applied to the card could be shorted out.

I can only assume, since the card works for other people in their systems, that there is some sort of power issue. This guide for the card says you need both a 6 and 8-pin power connection. I see in one of your screen shots that it looks like those are connected. Just wondering if the supply is actually doing its job there. Have you verified your connections are correct and work?

OP
Just a query
How are you Starting your PSU the one that supplies Power for the external Graphics Card ( paperclip trick on ATX 24 pin Connector ).
Are you Sure its Suppling power to Graphics Card ?

BINGO! You are a God. :peace::clap::love: That is the key to the solution. I did what you said yesterday. Then I ran out of all my beer and brandy.
I will give you a link to see the result. https://prohardver.hu/tema/gamer_notebookok/hsz_76584-76584.html
Thank you very much for your help. To all the people who commented on the problem. This mxm adapter is very good.
Who still loves your old laptop, this world, mxm connection ......this can be a good option for keeping alive. A unique implementation.
There will be another tuning later. A 3070Ti or 3080 as soon as I have enough money to do so.

Nice project! Does it works with its screen or do you need an external monitor?

The internal screen also works, only the fan rotates at full speed. Sg mode is not very good. Auto and PCIe are better.

@MR007RM i'm glad it worked out but you also need to understand the logic behind it. What you did is basically simulate desktop enviorment.
What NVIDIA did(to prevent desktop GPU's to be used that way,as eGPU) was to check for a presense of a battery and if there is one it would cripple or disable the GPU(usually ERROR 43 in Dev. Manager). But that changed at some point and those possums at NV decided to start blacklisting DEV_ID's instead(no solution is found as of now). So to summarize,that workaround will be possible until certain driver and your next step should be to find out which one is it(that basically will be the last driver that you'll be able to install). When you have time,start installing every driver pass yours and when you find the last one possible,install it and stick to it.
Other then that,enjoy your much more powerful laptop. :toast:

Very nice! This one is the best modding that i ever heard about gt 70. I ll try with one 3060 as soon as possible. I need to find a unlocked bios as well.

SG Is basically Intel GPU first(aka Optimus),you don't want that as i already saw it's set to MUXED.
IGFX: Intel GPU only !!!
PCIe: I'm not sure about this one to be honest.
PEG: Logically thinking here,this should be the one you set it on( PEG is short of PCIe Graphics) but there were many reports in the past that you'll lose the display and CAN'T recover afterwards. So i would not risk it !!!!
AUTO: That's your safe bet,just make sure whenever(in BIOS) says MUX/MUXED to be enabled.

P.S. Jeez....i just checked the link you posted and saw that you're with the latest driver,so....disregard my previous post. It sure doesn't apply to your situation.

PCIe option looks for a display adapter connected via the PCIe lanes from the south bridge.
PEG option is the same as above, only difference is that the lanes are from the cpu

The laptop has seen and used these cards so far.
Quadro k3100m, geforce 880m, 980m, 1070m, Quadro P5200 (mobile), RTX 5000 (mobile) ..... and now desktop rtx 2080.

The bios is from the techinferno forum. It was given to me by a bios expert a few more years ago.

Thanks to the adapter, the driver goes up to the card without modification. It doesn't matter what brand of vbios.

@MR007RM you OK do some small experiment on your end? No worries about damaging something,worst case scenario will be to reinstall the driver again,but i highly doubt it that it will come to this. I just want to see if it's possible to keep your battery on(enable the ACPI-Compliant Control in Dev. Manager) and still have the eGPU working,without showing the ERROR 43. Let me know.

If I turn it on afterwards, there will be no interruptions. There is a battery and there is also a vga card. If I enable it under Windows, the battery will come up and everything is old.

I'm not sure, but there may be a problem with RTX cards. I heard I read that a gtx 1070 worked flawlessly. I also tested a gtx 970 card and it was absolutely good.
