Hey everyone, I'm looking for some help with my PC build. I have an AMD Ryzen 9 7900X paired with an ASUS TUF Gaming B650-PLUS WiFi motherboard and I'm trying to run 4x16GB Corsair Vengeance DDR5-6000 RAM. The problem is that when I install all four DIMMs, the system fails to POST. It either gets stuck in a boot loop or shows the DRAM LED. Strangely, everything works fine with just 2 DIMMs in slots A2 and B2 at 6000MHz. When I add the other two sticks in slots A1 and B1, it won't boot, not even at lower speeds like 5800 or 5600. I've tried various solutions like resetting the CMOS, updating the BIOS, disabling EXPO, manually adjusting voltages, and even switching the sticks around, but nothing seems to work. Is this just a compatibility issue with the AM5 platform and high-speed RAM? Or should I consider returning this RAM kit and switching to 2x32GB instead?

Keep in mind, AMD CPUs are generally rated for a maximum of 3600 MT/s with four memory modules. It might be worth considering a 2x32GB kit instead if you can return what you have. That setup might give you better performance.
You might want to try disabling EXPO if you haven't done it already. Running the RAM at 4800 MT/s or lower could help with stability. But it sounds like you’ve already done some tweaking.
Yeah, I should've mentioned that I did disable EXPO, but still no luck.
Good point! I might just go that route since it's not even running at default speeds.
