I do know that AM5 with full bank memories, has an issue with memory clocks being dramatically down. And it defaults to 3600MT/s without any tweak on the BIOS.
My question is, some (probably rare) people manage to boot with 5200/5600MT/s with decent timings. But my system (With CPU: 9800X3d, MotherBoard: Asus B850M-PLUS II, RAM: SK Hynix "Klevv" CL30 6000Mhz 16G RAM x4). And I only manage to boot with 4400MT/s | 34-36-36-76 like in the screenshot.
My question is, am I on the low side? filling all four slots makes it closer to the silicon lottery or it is just really rare? And any possiblites to try tighten the timings?
