I’ve just bought the core x chroma and a dell XPS 9300 and put a EVGA 2060 Super in the egpu generally all works fine except a few windows crashing when disconnecting but the main issue is the usb was out don’t work very well device like mice and keyboards intermittently disconnects for a few seconds and then reconnects.

has any one else experienced the kind of issue and for a solution, currency Razer support I’d requesting an RMA but I don’t the the hardware is faulty

Does it happen even when you’re using only one port like mouse for example? Chroma X is similar with Core v2 has different lane to control io ports but there’s still bandwidth limitation so put too much pheriperals like using dongle might invite the issue.
For crashing when disconnecting, did you using external or internal monitor, and also switch off the 2060 inside Core chroma x before doing it? Driver crash may be the culprit.
yes ive tried with the mouse being the only attached device which is a wired mouse so no dongle, crashing happens with external monitors.

im not sure how to switch off card card before disconnecting ? can you please let me know.

Thanks 🙂

Ah so you didn’t switch off the nvidia dgpu on your blade? Sometimes it works fine but it might be a reason for the crash, driver crash, since this is optimus laptop, pc have to detect which gpu should work if you don’t disable dgpu it will maybe confuse choosing one, because without it literally 3 gpu might active, Intel, nvidia dgpu inside your Blade and 2060 in enclosure. You should disable dgpu on egpu setting, I use razer graphics switcher on my advanced 2018, but according some user it doesn’t work on their model, but you can manually disable it through device manager, display adapter and en/disable it by right clicking.
Try that first maybe it relates also to io port unstable connection.
Thanks the laptop is actually a Dell XPS 13 9300 but I have found I can eject the Graphics card from hot plug switch does a more stable disconnect the main issue I have it the USB port freeze on my mouse.
FYI Just an update the Ethernet port has also become problematic but i've got a swap out happening shortly
@bolto90 what steps did you take to set up your xps 9300? I can get mine to connect to the graphics card (AMD Radeon RX5700) but the frame rates are very low. I can't understand why as the laptop egpu set up seems to work for others on the forum.
Nothing special really just installed the drivers for the gpu from Nvidia and disable the link power states stuff link in the link below.

I’m not a big gamer to be honest but benchmark all come back pretty good
