Question My eGPU is not working.

[Killian Preston]

When I plug the egpu into the mPCIe slot on my laptop it does this:

I adapted mPCIe to PCIe 1x then adapted PCIe 1x to PCIe 16x.

The mPCIe adapter I bought: https://www.amazon.com/gp/product/B07GTH26X5/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

The PCIe 1x to 16x adapter I bought: https://www.ebay.com/itm/4PIN-USB3-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

Please help me it would be great, thanks.

1. Your pic link appears to be broken
2. your mPCIe slot might not be enough for graphics
3. PCIe x1 is absolutely not enough for graphics. Not matter what 'adapter' you glue onto it.
4. How are you powering the GPU? That molex thing is absolutely not enough

Also, what are all the parts in this system? To include the GPU and what OS?

It is a hp EliteBook 840 G1 with a Core i5-4300U. I am trying to use a Gtx 1060 6gb. I have a power supply plugged into the power input on the graphics card and both adapters. I am running windows 10 pro.

I got my egpu to work on my old laptop, but when I plug it into the pcie on my new laptop it doesn't work. I think it is an issue with the laptop trying to take the graphics card video and feed it through the internal display. It doesn't seem to be the whitelist stopping it because it starts up without an error message when there is no network card installed.

Although a PCIE 3.0 1x is about 1GBps transfer speed, it would still be enough bandwidth to run a GTX 1060 at about 45% of it's full potential or a bit slower than a GTX 1050. The issue though is your particular laptop may have a white-list that only allows qualified or certified hardware to function on the slot you are trying to use. You would need to find a way to trick it or white-list it to function.

How do I do that?

I'm not sure why I missed it before, but I just had another look at what parts you bought and what you said in the original post. So not only did you adapt the parts incorrectly it looks like you bought at least one wrong part. The only part you bought that might work (but probably won't) is the 1x mPCIE adapter, but you never mentioned how you are powering the video card externally. That 1x mPCIE adapter also requires external power so it was never going to work in the first place.

You need to externally power the video card with a power supply that will need to be jumpered so you can turn it on from it's own switch. You may also need to get a different mPCIE adapter like this one https://www.banggood.com/Mini-PCI-E...p-1011222.html?rmmds=search&cur_warehouse=USA

Edit I should clarify that the power supply I meant is just a regular computer system power supply like this https://www.newegg.com/corsair-cx-series-cx450-450w/p/N82E16817139201.

I have both my adapters externally powered. I know the adapters and gpu work fine because they work on my old laptop and not my new one.

Ok, well then you just need to get your parts whitelisted on the laptop to function if that is actually why it's not working. I've never done it before and I have no idea if it's even possible on your laptop without destroying it.

It could still be that the slot just won't accept the hardware you are trying to use if there is no whitelist. I can't really help you honestly.

Ok, well thank you for trying.

Hello, I am having the exact same problem as shown in the picture, I have a elitebook 820 (which I guess is very similar to yours). Although I am using the complete EXP GDC Beast setup through mPCIE. Although I made it work on a different laptop (Dell Latitude something) but it just doesn't work on my Elitebook 820. If someone has the solution or if you have made it to work then please let me know. It will be really appreciated. Thank you in advance.
