Hi, In my region AMD RYZEN 5 3500X 100-100000158CBX is available. However the CPU support page for this board B550M Pro4 says Ryzen 53500X (100-000000158). So there is no CBX after 158 in the part number. Is AMD RYZEN 5 3500X 100-100000158CBX supported by this board£ Thanks. |

It should be, from what I can tell, CPUs with the suffix CBX tend to be sold/imported from China directly. I would guess it stands for China BoXed£ Given it is just a suffix I am fairly sure it will work with any board that supports the standard Ryzen 5 3500X (without the suffix). If it were based on different silicon it would have a different model number, not just a suffix. Basically CBX models are typically sold in China, based on what I can find on the web. It's probably just something added to verify they comply with local Chinese laws and regulations. I don't see why it would not work. I don't see any CBX suffix parts listed on any QVL so I suspect it actually means nothing to compatibility. -------------
