All Ryzen CPUs are potentially affected. See: https://community.amd.com/thread/215773 Not all Ryzen CPUs are affected, only ones produced until some time during the spring (week 25 CPUs are said to be good). It is a good idea to flash the latest BIOS before doing anything else. Many Ryzen bugs can be worked around with BIOS supplied firmware. The segfault bug might not have a firmware fix, though. AMD asks customers to mess around with CPU voltages before RMAing their CPUs. That's just disrespectful and a little bit silly, IMO. -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ cfarm-users mailing list cfarm-users@lists.tetaneutral.net https://lists.tetaneutral.net/listinfo/cfarm-users
