Tw\u00f3rcy biblioteki GNU MP (GMP), kt\u00f3ra udost\u0119pnia funkcje do wykonywania operacji arytmetycznych z dowoln\u0105 precyzj\u0105, ostrzegli u\u017cytkownik\u00f3w o incydencie ponownego awariowania procesor\u00f3w serii AMD Ryzen 9000 opartych na mikroarchitekturze Zen 5 podczas testowania dzia\u0142ania biblioteki. Przypuszcza si\u0119, \u017ce uszkodzenie procesor\u00f3w by\u0142o wywo\u0142ane przegrzaniem, kt\u00f3re wyst\u0119puje podczas intensywnego wykonywania funkcji GMP. Do czasu zako\u0144czenia pe\u0142nej analizy problemu u\u017cytkownikom nie zaleca si\u0119 aktywnego korzystania z GMP na systemach z procesorami AMD Zen 5. <\/p>\n

Obawy s\u0105 spowodowane ponownym awariowaniem procesora AMD Ryzen 9950X (AMD Zen5 X16 4300MHz) w serwerze<\/a> infrastrukturze testowej projektu. Pierwsza awaria mia\u0142a miejsce w lutym 2025 roku, po czym procesor zosta\u0142 wymieniony w ramach gwarancji. Pod koniec sierpnia sytuacja si\u0119 powt\u00f3rzy\u0142a, a wymieniony w ramach gwarancji CPU, zainstalowany w systemie z innym zasilaczem i inn\u0105 p\u0142yt\u0105 g\u0142\u00f3wn\u0105, r\u00f3wnie\u017c przesta\u0142 dzia\u0142a\u0107 z tymi samymi objawami, wskazuj\u0105cymi na przegrzanie (na chipie powsta\u0142a odbarwiona strefa o \u015brednicy oko\u0142o 1 centymetra).

\"Mo\u017cliwe<\/center> <\/p>\n

Wed\u0142ug wst\u0119pnych danych biblioteka GMP zbyt intensywnie wykorzystuje cykle z instrukcj\u0105 MULX, co prowadzi na systemach z AMD Zen 5 do zu\u017cycia znacznie wi\u0119kszej ilo\u015bci energii ni\u017c zadeklarowano oraz niemo\u017cno\u015bci zrekompensowania ciep\u0142a systemem ch\u0142odzenia, dobranym zgodnie ze specyfikacj\u0105. W trakcie obu uszkodze\u0144 przeprowadzano testy z r\u0119cznymi cyklami assemblerowymi z jedn\u0105 instrukcj\u0105 MULX, kt\u00f3re generowa\u0142y maksymalne obci\u0105\u017cenie. <\/p>\n

W systemach u\u017cywano p\u0142yt g\u0142\u00f3wnych Asus Prime B650M-K i Asus Prime B650M-A WIFI II oraz zasilaczy Corsair SF450 i Corsair RM650. W obu konfiguracjach zastosowano system ch\u0142odzenia Noctua NH-U9S, jednak w pierwszym przypadku radiator by\u0142 zamontowany na \u015brodku, a w drugim zgodnie z zaleceniem producenta przesuni\u0119ty w stron\u0119 z wi\u0119kszym nagrzewaniem. <\/p>\n

Zauwa\u017cono, \u017ce w drugim przypadku pasta termoprzewodz\u0105ca by\u0142a rozprowadzona nier\u00f3wnomiernie (z jednej strony warstwa by\u0142a cie\u0144sza) i ca\u0142kowicie nie mo\u017cna wykluczy\u0107, \u017ce druga awaria by\u0142a spowodowana niew\u0142a\u015bciwym monta\u017cem radiatora. W procesorze CPU Ryzen 9950X wymagana jest moc cieplna wynosz\u0105ca 170 W (TDP, Thermal Design Power), a stosowany system ch\u0142odzenia zapewnia\u0142 odprowadzenie ciep\u0142a na poziomie 165 W. Brakuj\u0105ce 5 W zrekompensowano dodatkowymi wentylatorami w obudowie oraz nisk\u0105 temperatur\u0105 w pomieszczeniu, wynosz\u0105c\u0105 oko\u0142o 20\u00b0C. Oba procesory uleg\u0142y awarii po kilku miesi\u0105cach pracy pod du\u017cym obci\u0105\u017ceniem. W mi\u0119dzyczasie w infrastrukturze projektu do innych zada\u0144 od d\u0142u\u017cszego czasu wykorzystywany jest jeszcze jeden serwer<\/a> w tej samej konfiguracji i z tym samym poziomem obci\u0105\u017cenia, i nie wyst\u0119puj\u0105 z nim \u017cadne problemy.
