messenzer

I want to connect the laser core x, but when I connect it, it keeps turning off. The screen doesn't come out.
But try again again and again, put plug it in, it can work again.
I can't power off or reboot cause doesn't not operate.
A pcie warning and whea logger appears in Windows Event Viewer, but I can't fix it in cmos.
What's the problem? Help me.

Hi,

Turn on the EGPU and plug in a USB stick or other USB device on the standard USB next to USB-C. And make sure that the Intel Thunderbolt is caught in the BUS of HWINFO (software).

Hi,

Turn on the EGPU and plug in a USB stick or other USB device on the standard USB next to USB-C. ...

I tried to effort for using egpu with 7735hs very many many many times.
And finally find method only one.
Method is below.
*must using TB3 cable(3ft)
1. turn on the power(7735hs)
2. turn on egpu power after must 5second
3. don't turn off power. System down if 7735hs shutdown.
4. but hibernate mode is not system down.

This is try list.
1. change the cable(Orico TB4 cable 1.5m, TB4 cable 50cm, Sky USB4 cable 1.5m)
2. change the body(7735hs) to new one.
3. change the power adapter.

all that same :(

1. Green screen showed in windows If connect to egpu after booting. (cmos is normally showed)
2. Egpu is can't turn on if using TB4 and USB4 cable. It looks like a problem with egpu power.
3. It is not operate egpu when I connect hdmi to egpu after hdmi connect to 7735hs.

I wanna solve this problem :(
