X server crashed after the driver installed's reboot on rtx 2080

I bought a zotac rtx 2080 last week with a Z390 aorus elite. And I want to fit them into ubuntu system.
As I tried 18.04 and 16.04 with different version drivers(ppa and .run also), I always got the same crashed after reboot.

Linux jiarung 4.15.0-45-generic #48~16.04.1-Ubuntu SMP Tue Jan 29 18:03:48 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Try reseating the card, check in another system, then RMA.
