Ochungechungeni lwe-AMD EPYC 2018 (βRomeβ) lwamaphrosesa weseva alethwe kusukela ngo-7002, olwakhelwe phezu kwe-βZen 2β microarchitecture, kubonakale iphutha ngenxa yokuthi iphrosesa iqhwa ngemva kwezinsuku eziyi-1044 zokusebenza ngaphandle kokusetha kabusha isimo. ukuqalisa kabusha isistimu). Njengendlela yokusebenza ukuze uvimbele inkinga, kunconywa ukuthi ukhubaze usekelo lwemodi yokonga amandla ye-CC6 noma uqalise kabusha iseva ngaphezu kokukodwa njalo ezinsukwini eziyi-1044 (cishe iminyaka emi-2 nezinyanga eziyi-10).
Ngokolwazi olushicilelwe yi-AMD, i-hang ibangelwa ukwehluleka okwenzeka lapho umgogodla weprosesa uzama ukuphuma kumodi yokonga amandla ye-CC6 (i-core-C6, yehlisa i-voltage uma ingasebenzi) lapho isibali sikhathi sifinyelela ezinsukwini eziyi-1044 ngemuva kwe-CPU yokugcina. setha kabusha (isikhathi esisithathayo ukwenzeka singahluka kuye ngokuthi imvamisa ye-REFCLK).
I-AMD ayinikezi incazelo enemininingwane yembangela yokwehluleka. Uma sibheka umcabango oshicilelwe ku-Reddit, ukubanda kwenzeka lapho ikhawunta kurejista ye-TSC (Isitembu Sesitembu Sesikhathi), esibala inani lemijikelezo yomsebenzi ngemva kokusetha kabusha, imvamisa engu-2800 MHz ifinyelela inani elingu-0x380000000000000 (2800 MHz * 10) ** 6 * 1042.5, okungukuthi ngemva kwezinsuku ezingu-1042 namahora angu-12).
Azikho izinhlelo zokushicilela ukulungiswa kweziphazamisi. Inkinga yahlala ingaziwa isikhathi eside njengoba isikhathi eside sokugcina singejwayelekile kumaseva, okuthi, ukuze agcinwe esesikhathini samanje, kumele aqaliswe kabusha ngezikhathi ezithile ukuze kufakwe izibuyekezo ze-kernel noma kuthuthele ekukhishweni okusha kwesistimu yokusebenza. Kodwa-ke, izindlela zokusatshalaliswa kwe-Linux zokuvuselela i-kernel ngaphandle kokuqalisa kabusha, kanye nemijikelezo yokulungisa emide (Ubuntu, i-RHEL kanye ne-SUSE isekelwa iminyaka eyi-10), ingaholela ekutheni amaseva ahambe isikhathi eside ngaphandle kokuqalisa kabusha.
