AMD admits that the EPYC Rome server chip will crash after running for 1044 days.

CTOnews.com June 4 news, AMD recently released EPYC 7002 "Rome" server chip guide, admitted that due to the existence of BUG clock countdown timer, resulting in the second generation of EPYC chip kernel jam 1044 days after normal operation.

Servers using the EPYC chip need to be restarted every 2.93 years, and AMD officials said they would not fix the BUG.

AMD says in the guide that the reason for this problem is that the kernel cannot leave the CC6 power saving mode (Core C6 State), which lowers the voltage and clock frequency. AMD clarified that the timing of the error may depend on spread spectrum modulation and REFCLK frequency reference.

After detailed calculation, Reddit user acid_migrain believes that the actual time that caused the jam is not 1044 days, but 1042 days and 12 hours.

CTOnews.com Note: AMD launched the EPYC "Rome" series of server chips in 2018, and some customers have reported this problem to AMD. The plan put forward by the foreign science and technology media technewsspace is as follows:

1. Restart the server every 1044 days

two。 Disable CC6 power saving mode

AMD said that there are no plans to fix the vulnerability, foreign technology media technewsspace believes that either the repair cost is too high, or the number of affected users is small.
