R\u00e9cemment, AMD a fourni une nouvelle version d\u2019AGESA aux fabricants, la ComboAM4 1.0.0.3 ABB. Cette derni\u00e8re optimise notamment les tensions et fr\u00e9quences des Ryzen 3000<\/a>. Gigabyte l\u2019a d\u00e9ploy\u00e9e sur ses cartes m\u00e8res des s\u00e9ries 300 et 400. Malheureusement, le firmware supprime \u00e9galement la fonctionnalit\u00e9 PCIe 4.0. <\/p>\n\n\n\n

On sait depuis longtemps qu\u2019AMD ne voit pas l\u2019activation du PCIe 4.0 sur des cartes m\u00e8res d\u2019anciennes g\u00e9n\u00e9rations d\u2019un bon \u0153il. Outre Gigabyte, plusieurs fabricants, comme Biostar<\/a> ou Asus<\/a>, avaient toutefois activ\u00e9 la fonctionnalit\u00e9. Le journal des modifications<\/a> de la version BIOS F42a, qui concerne les chipsets X470 \u00e0 A320, stipule qu\u2019en “raison de la version 1.0.0.3 ABB d’AGESA, le support PCIe Gen4 a \u00e9t\u00e9 supprim\u00e9 lors de l’utilisation d’un CPU Ryzen 3\u00e8me g\u00e9n\u00e9ration (Matisse)”<\/em>. Notez que Gigabyte a rajout\u00e9 le “en raison” a posteriori<\/em>, comme en t\u00e9moigne une capture d’\u00e9cran partag\u00e9e par Guru3d<\/a>. Il faudra attendre que d’autres fournisseurs publient eux-aussi cette version du BIOS pour leurs produits afin d\u2019avoir la r\u00e9ponse d\u00e9finitive.
