All AMD Ryzen Threadripper Pro 5000WX processors of the recently introduced Chagall series are officially “tied” to Lenovo P620 workstations. The information is supported by documents discovered on Lenovo’s website stating that these chips can only be used in its standard systems.
Lenovo uses the PSB (Platform Secure Boot) feature to “bind” the Ryzen Threadripper Pro 5000WX chips to its systems. Its support is built into all modern AMD enterprise-class processors. According to the description, the function is a powerful anti-malware protection that offers security against remote attacks on software. In addition, PSB is used as a tool against hardware theft. It eliminates the possibility of using a stolen CPU as part of another system. However, PSB only works if the stolen processor is used in a third-party PC.
The feature “binds” a specific processor to a specific motherboard model from a specific manufacturer using special BIOS firmware keys. It is impossible to “unclip” the chip from this motherboard and use it on another board. It should be clarified that the “binding” is done at the time of assembling a particular workstation and not directly at the AMD factory. That is, in this case, Lenovo is directly involved in “tying” the processors to its P620 stations.
