Just upgrade my AB350 Fatal1ty ITX bios to 5.30 and now i can OC RAM to 3600 which is awesome. But the downside is GPU Bus type from x16 3.0 to x8 3.0. I checked by both AIDA64 and GPUZ, all reported same. Pretty sure this is an bios problem b/c i experienced the same on BIOS 3.60 but it's gone with 3.40 (or vice versa b/c i'm not remember well T.T) Anyone have same problem? Sorry for my poor English b/c it's not my native |

Try to find GPU bus type in UEFI. In my 4.71A version (not published official by ASRock) i have 3 settings in Advanced: - PCIe x16/2x8 Switch - PCIe x16 Switch - Promontory PCIe Switch all should be set to Auto. P.S. can you specify the RAM symbol? ------------- AB350 Gaming-ITX/ac 10.31 BIOS| Ryzen 5 5600| G.Skill Flare X 2x8GB @ 3466 14-14-14-28| Zotac RTX 5060 SOLO| Kingston KC3000 1 TB M.2| SilentiumPC Supremo M2 Gold 550W V2| Plywood case 24x22x21 cm |
