System fails to start after adjusting RAM frequency beyond 4800MHz

It's my first time assembling a PC. My configuration includes: Ryzen 5 7600, Msi Mag Tomahawk B650 motherboard, two 16GB DDR5 6000MHz RAM sticks (XMP enabled), Corsair RM850x power supply. So far, I'm only using the built-in graphics of the CPU. The issue is that the default speed for DDR5 RAM is capped at 4800 MHz. My RAM supports up to 6000 MHz, but when I try to boost it above that (including XMP), the system activates fans and RGB lights, but I don't see any connection to my monitor. I can't access BIOS or Windows, and the yellow RAM debug light flashes briefly. Resetting the CMOS brings everything back to 4800 MHz and works, but changing it again causes the same problem. I've already tried reinserting the RAM. The CPU cooling is stable at around 36°C, and the BIOS seems up to date. I'd prefer not to update it just in case, as I don't want any risks after assembly. Please help me if you can.

Do you see a choice labeled "XMP 1" that matches 6000MHz with precise RAM timing and voltage settings (like 30-36-36-76 at 1.4V)? If not, what does this "XMP 1" feature actually do?

It mentions Profile1: DDR5 6000MHz 30-36-36-76 1.400V as per the specifications, but the settings fail to apply when saved.

It's frustrating when this occurs, but it seems your CPU/Mobo setup isn't syncing well with the RAM configurations. You might want to attempt a manual RAM overclock, as it could be addressing some underlying timing issues. While the slower speeds aren't ideal, they probably won't significantly impact overall performance.

Your motherboard features four RAM ports. Are your memory modules positioned with a gap of one slot between each other?

Exactly as the motherboard manual states. Perhaps I can locate some YouTube videos about overclocking RAM.

Your specific kit might not be listed in the QVL. Could you share the exact RAM model? For Corsair, their identifiers are examples like CMH32GX5M2X6000C30. Keep in mind, the Vengeance RGB DDR5 6000 CL30 is available in the QVL, while standard DDR5 CL30 Vengeance isn't. This affects whether XMP/DOCP/XPO features are supported.

It seems it isn't on the priority list. I should have examined it more thoroughly. The performance won't be affected much, though it's still unfortunate.

Just a reminder, QVL isn't a simple "get this or not" list. It's about confirming the product performs as rated, anything outside those specs is uncertain, and results aren't guaranteed. You can still experiment, but success isn't assured.
