I'm in the process of building a PC with a Ryzen 9 9800X3D, an MSI B650 Pro VC WiFi motherboard, and a PNY 5080 graphics card. I recently traded for some Corsair Vengeance DDR5 RAM (the CMK32GX5M2B6400Z32 model) that runs at 6400MHz and CL32. Unfortunately, I overlooked the fact that this specific RAM isn't listed as compatible with my motherboard. While it functions at the base frequency, enabling EXPO or tweaking any settings causes it to fail to post. I've spent hours trying to sort this out and am considering switching to an X670 or B650 motherboard instead, but I want to avoid making another mistake. Does anyone have recommendations for a compatible board?

Have you tried dropping the RAM speed down to 6000MHz? Higher frequencies can be a hassle with Ryzen builds, especially if they aren't fully compatible. Lowering the speed might help you get it stable!
I actually tried that, and even adjusting to stock settings at 4800MHz still didn't post. The yellow DRAM light goes on, and I’ve let it sit for a while to see if it would stabilize, but no luck.
