Hi all, I'm new around here. I am experiencing a little issue with my setup.

Specs:

  1. Laptop - DELL XPS 13 model 7390 2in1, i7-1065G7, 16GB DDR4 3733MHz, Iris Plus Graphics

  2. eGPU - Razer Core X Chroma with an ASUS STRIX GeForce GTX 980 4GB inside.

Windows I am running is Windows 10 Pro 64 bit, ver.21H1

I normally run everything through "external monitor only" that is linked to the GPU via straight HDMI wire. I don't use the laptop screen while it's plugged into the GPU. I use only one monitor with the GPU.

The issue I am experiencing is, if the laptop is turned off, I plug in the thunderbolt cable, leave it for a few seconds and then turn on the laptop (with the monitor plugged into the GPU), it will stay forever on the DELL post logo and won't boot into windows. I have found a workaround, by unplugging the HDMI cable from the graphics card (it boots fine if the monitor is unplugged), booting the laptop up and once it boots to windows, plugging the HDMI again. Then the output changes from internal screen to external monitor and I can use it as intended. I hope you can imagine how annoying that is, having to re-plug the cable every time I turn the laptop on, not to mention the increased wear & tear I will cause on the HDMI port. I have tried different configurations, DP-DP cable, DP-HDMI, DVI-HDMI, HDMI-HDMI, nothing changes. I have reinstalled the nvidia driver after changing the GPU (even though it's the same exact driver)

I had an RTX 3070 borrowed for a day as a test before installing this GTX 980, and I do not think I recall having that issue. I've only started noticing it after changing the graphics card. I could borrow that 3070 again to verify that for certain, of course. I also can get my hands on a GTX 1070 and a GTX 1080Ti for testing if need be.

Did anyone experience something like this? Is that something that's expected to happen due to using HDMI? I have enabled Thunderbolt boot and pre-boot support, PCI-e behind thunderbolt etc, everything is all turned ON.

I would appreciate any suggestions or help.

I have found out the solution to the problem, so i'll post it here in case someone else needs in future. It's not ideal, but i believe there is no ideal solution in this case.
 
The short answer is - don't use old graphics cards.
 
The detailed answer is - i got two GPUs to test instead of my gtx980. i got a 1070 and a 3070. i have tested them both and both of them work absolutely spot on, whereas the 980 has issue with booting while plugged into a monitor.
I have done some cross-referencing and i suspect it may have something to do with the fact that GTX980 was released a year before the TB3 standard was. The GTX1070 was released a year after TB3 was released, so it may have some better tech made to work with thunderbolt devices. I don't think there's need to expand on the RTX3070.
So the end conclusion is - if you're going for a Thunderbolt 3 eGPU case - make sure that you pair it with a GPU that has been released after the date when TB3 came out (December 2015)
 
Good Luck Everyone!

@_lomax_, I have some info/Data on this one! I have an XPS 13 9310, Using Razer Core X Chroma and a 1070

It took me like a month to work around the issues I have

Every time I boot up the PC and the Razer is plugged in to the laptop, I get a pop up from the BIOS [I think] asking me if I want to boot from the EGPu - If anyone knows what I need to do to get rid of that I would love you 5ever

When it does give me that message, I usually have to unplug it, then do a hard reset holding the power button, when I boot it back up it says there was an issue restarting and asks if I want to continue or turn off/restart the laptop

After I click turn off and reboot it, I can then plug in the EGPu and everything works perfect. 

BUT even unplugging the EGPu and plugging it back in will break everything, I have to go back through the hard reset, then power off from the BIOs then boot it back up

 

Also if you have any tips on settings to improve performance I am all ears

 

 

OH And last thing, do you think the new Razer Kunai Fans would work to replace the fan? Hate having RGB on just one side, even though I just use a basic white glow, looks odd with the fan side not having any color 

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Hi David Lang,

I am nowhere near an expert on the matter, i have also since then moved to a full size desktop and i don't use the eGPU anymore.

That being said, afaik the PCI-e eGPU is not hot-swappable and you should avoid plugging/unplugging the eGPU while the laptop is powered on.

I used it while having it permanently hooked up to the laptop.

Additionally, Razer Core X Chroma can serve as your laptop's PSU, as it can provide up to 100W of power through the TB3 cable.

Make sure that in your BIOS, you have enabled all the options that pertains to thunderbolt.

As for the fans, i wouldn't be able to give you insight as i haven't done any modifications to my box. But afaik as long as you can wire the fan in to power it on, there shouldn't be any complications.

Hope this helps!

Lomax
