Hello helpful community member:

I'm trying to create a six-monitor setup for my MSI Summit laptop, which has Thunderbolt 4. This is for work, not gaming. I bought a Razer Core X Chroma and a card with six mini DisplayPorts (VisionTek Radeon 7750 2GB GDDR5 6 4k, AMD Eyefinity 2.0, PCI Express 3.0). I’ve tried setting this up several times and always with the same result. I install the graphics card in the enclosure. I connect the enclosure to the laptop with the provided Thunderbolt 3 cable. I power on the laptop and the Core X Chroma and all seems good. The Chroma lights come on. Windows sees the graphics card and I install the recommended driver. I then test it by plugging in a couple monitors and they work. Everything seems fine… except… when I restart my laptop, it enters a loop of BSOD “ACPI_BIOS_ERROR,” then restarting to the “Preparing automatic repair” screen, and then back to BSOD “ACPI_BIOS_ERROR,” and the loop continues. I can press and hold the power button to shut down the laptop, but it automatically restarts. The only way to turn it off is to disconnect the power cord and then press and hold the power button, which does shut it down without a restart.

--I have updated the laptop BIOS. That hasn’t impacted anything.

--I have connected the laptop to the Core X Chroma without the graphics card installed and the result is the same, so this doesn’t seem to be the fault of the graphics card or the graphics card driver.

--I bought the Core X Chroma on Amazon and had this problem, so I returned it and bought a new one Core X Chroma behaves the same way, so it doesn’t seem to be a faulty Core X Chroma.

POTENTIAL CLUES?

--In the 6-8 times I’ve done this process, I’ve never seen the Core X Chroma’s window “Approve Thunderbolt devices” window where one is supposed to select “Always Connect.” That’s strange.

--I have managed to turn the laptop on without the BSOD loop by pressing and holding the firmware reset button on the bottom of the laptop for 45 seconds and then forcing the laptop to power down three times and then pressing repeatedly the F3 button on power up. But this only works about 1 in 5 tries. I honestly don’t know if doing these things has any effect of if it just randomly sometimes starts without the loop. After I get into Windows, I either repair or do a system restore to make it functional again, and then my laptop is good as new, until I connect it to the Core X Chroma again.

I have a Prestige 15 with an 11th gen and chroma and have the same issues. I've gone through all the power recommendations turning off power save etc. ddu/drivers, disabled the dgpu in the os and the error always comes back, I noticed flashing the bios update reset something and it starts working and then it fails again as soon as it's started without the egpu plugged in. I haven't tried the ec reset yet will try it next time.

It's like a conflict or something needs to be changed in the bios settings but I can't make any sense of the advanced settings (hold left ALT+right CTRL+right SHIFT+FN-F2).

@dadudeondacouch, My MSI Summit E15 laptop is currently stuck in the loop of “Preparing automatic repair” --> BSOD “ACPI_BIOS_ERROR” --> Restart --> and looping from there. Nothing I try is allowing Windows to boot. Have you found a way out of the loop?

@steve47, for me reflashing the bios is the only way, it reboots several times and then boots normally, I couldn’t even boot to a usb drive to reinstall or repair when the loop occurred.

it’s got me stumped at the moment it’s like it sets something off in the bios and the only way to reset it is to flash it.

@dadudeondacouch, Thanks! I'm relieved that my laptop can now boot Windows. Now let's hope for some guidance on connecting our laptops to the Core X Chroma enclosure! : )

I decided to order a MasterCase EG200 eGPU enclosure. It arrived today. It was nearly plug-and-play with my MSI Summit 15. I'm going to return the Razer Core X Chroma. It's a shame, because I'm paying an extra $100 for an enclosure with fewer USB-A ports, no Ethernet port, and I need to use one of my laptop's USB-A ports to power the MasterCase EG200. But it is a bit smaller, so there's that. Thank you to @dadudeondacouch and the rest of the egpu.io community for helping me through this process.

@steve47, Yeah I understand it's a bit of a headache to deal with but I'm slowly figuring it out.

So far this is what I have...

Starting the pc with the Razer Core X Chroma plugged in causes no issues at all.

I have to disconnect the device using the app in the taskbar which disables the gpu in device manager and then unplug the egpu before shutting down or the bsod will occur next boot. This is what causes the whole issue.

 

My current workaround is to do the above when shutting down and I used gpedit.msc to add a user login script (powershell) to detect if the device is connected and re-enable it if it is this will go on every 30 seconds for 10 minutes

Script to do this is at https://egpu.io/forums/pc-setup/script-poll-for-egpu-enable-it-and-disable-dgpu-when-its-detected/

@dadudeondacouch, Thanks for that update. I returned my Razer Core X Chroma and bought a MasterCase EG200 for the same graphics card. This doesn't have the BSOD problem. But my laptop does freeze about every other day and I need to hold down the power button to reboot. It seems to happen when it's coming out of sleep or going into sleep, but I'm not certain on that yet. The freeze once prompted a window asking me to send a bug report to AMD because "your graphics card malfunctioned" or some such - so it does seem to be eGPU related. I'm wondering if either Windows or the graphics driver hasn't yet made compatibility updates for Thunderbolt 4 laptops/PCs. I'm hoping that when I update to Windows 11, maybe this issue will somehow go away.
