The motherboard is malfunctioning and causing issues.
Details: AMD Ryzen 7 5800X3D issue traced to MSI B450 Pro Carbon. Early non-max version had limited UI bios because of 16MB chips, causing AGESAs problems. Corsair LPX 16GB DDR4-3000 CL15 slots have been unreliable lately, making PC moves or desk bumps frustrating. Recent crashes are mostly Windows install or motherboard-related. Possible choices: Option 1 – sell the CPU, upgrade to new RAM and CPU, plus buy a whole system. Pros: fresh start; Cons: expensive, selling CPU feels risky, reinstalling Windows again, uncertain good AM4 boards now.
I tested a 5800x3d for years on a budget MSI B350M motherboard without any issues. It’s not necessarily your chipset, but you might be mixing it up with RAM. I’d avoid that route and stick to AM4 for a while longer. Newer GPUs should work fine. I now have a B550M MORTAR with Wi-Fi (just bought it mainly for the built-in Bluetooth). It’s simple but reliable. Think about getting a Gskill Trident Z kit—two sticks are great, especially if they include the stickers.
The restricted UI doesn't hinder performance. Soldering on a 32MB chip should be manageable if it is, which could be useful when purchasing another MSI B450 later. This model would be a good choice, but since it's outdated, consider buying a newer one around $50 or a used B550 if it offers similar specs without the high cost. For optimal results, go with the B550/X570 AORUS Pro/Master or the unified X570, though those boards won't fully utilize DDR4 5600+ features and are quite pricey.
