Can you please elaborate your post concerning what you are asking. Also please post your computer information as per AMD Forum rules: INFORMATION REQUIRED WHEN POSTING A QUESTION .
Are talking about the plastic bracket that is used to install the Ryzen CPU/APU to the motherboard?
Hi and thank you. Yes "AMD Carrier SP3" is the part name for the orange plastic carrier. I cannot find anywhere that sells them.
Someone else asked the same question here at AMD Forum: AMD ThreadRipper mounting bracket replacement?
As I commented on that thread, Open a AMD EMAIL Support ticket and see if they can guide you on where to get another Orange Carrier Frame for your Ryzen.
Better yet, open a AMD WARRANTY REQUEST FORM and see if AMD will send you a replacement under warranty; https://support.amd.com/en-us/warranty/rma
Someone else I believe was able to find a source that sold them separately but I couldn't. It seems like the Carrier frame is part of the CPU as a whole and not sold separately.
