Some AMD Ryzen™ processors are locked: you can't change the platform

Due to the low price, many domestic DIY players are very fond of the sea amoy large ship cargo, that is, the manufacturers dismantled the accessories, the common is a variety of scattered chip processors, but now the situation has changed, some AMD Ryzen™ processors are locked, can not change the platform to use.

In recent times, this matter has aroused the attention of netizens in overseas communities, mainly because some of Lenovo's computer hosts use AMD's PSB technology, which was originally used to improve system security and prevent computer startup from being attacked.

Processors that support PSB technology will verify the hardware manufacturer's UEFI firmware during the boot process to prevent unauthorized boot, but the consequence of it is that the processor will be "locked" and cannot be used if the platform is changed.

AMD's PSB technology, which is mainly used for EPYC server processors in 2020, began to be enabled by default in the Ryzen Pro product line at the end of last year, which is actually a commercial version of the AM4 platform Ryzen, and the technology is basically the same.

At present, the PC manufacturers that enable PSB technology are mainly Lenovo (other manufacturers may also have it, but the exposure is mainly Lenovo), which means that some of Lenovo's computer products cannot be started on other platforms after disassembling, and they are really going to become garbage.

Now this matter has not been fully reflected to the domestic sea tao market, after all, the Ryzen Pro has just been listed not long ago, there are not many dismantling goods, but we still have to be more careful, second-hand trading Ryzen processors to pay attention to.
