Mon système ne reconnaît qu'un seul cœur de CPU et un seul thread (j'ai également eu de nombreux problèmes pour faire en sorte qu'Ubuntu se charge sans décrocher). Le système d'exploitation fonctionne très mal, quelle que soit la charge.
Here are the system specs:
OS: Ubuntu 19.04
Motherboard: Gigabyte Z390 AORUS PRO WIFI
RAM: 16GB
Storage: ATA Samsung SSD 860; ATA WDC WD10EZEX
