Udviklerne af GNU MP (GMP)-biblioteket, som tilbyder funktioner til at udf\u00f8re aritmetiske operationer med vilk\u00e5rlig pr\u00e6cision, har advaret brugerne om en h\u00e6ndelse med gentagen fejl p\u00e5 AMD Ryzen 9000-processorer baseret p\u00e5 Zen 5 mikroarkitekturen under testning af bibliotekets funktionalitet. Det antages, at skaden p\u00e5 processorerne skyldes overophedning, der opst\u00e5r under intensive udf\u00f8relser af GMP-funktioner. Indtil en fuldst\u00e6ndig analyse af problemet er afsluttet, anbefales det ikke aktivt at bruge GMP p\u00e5 systemer med AMD Zen 5 CPU. <\/p>\n

Bekymringerne skyldes gentagen fejl p\u00e5 AMD Ryzen 9950X (AMD Zen5 X16 4300MHz) p\u00e5 serveren<\/a> testinfrastrukturen for projektet. Den f\u00f8rste fejl opstod i februar 2025, hvorefter processoren blev udskiftet under garanti. I slutningen af august gentog situationen sig, og den erstatte CPU, som blev installeret i et system med en anden str\u00f8mkilde og et andet bundkort, stoppede ogs\u00e5 med at fungere med samme symptomer, der vidner om overophedning (der dannedes et misfarvet omr\u00e5de p\u00e5 chippen med en diameter p\u00e5 cirka 1 centimeter).

\"Mulig<\/center> <\/p>\n

If\u00f8lge forel\u00f8bige oplysninger bruger GMP-biblioteket for intensivt cykler med MULX-instruktioner, hvilket f\u00f8rer til en betydeligt h\u00f8jere energiforbrug p\u00e5 systemer med AMD Zen 5 end oplyst, og til at k\u00f8lesystemet, der er tilpasset specifikationen, ikke kan kompensere for opvarmningen. Under begge skader blev der udf\u00f8rt tests med manuelle assembly-cykler med \u00e9n MULX-instruktion, der skaber maksimal belastning. <\/p>\n

P\u00e5 systemerne blev der brugt bundkort Asus Prime B650M-K og Asus Prime B650M-A WIFI II, samt str\u00f8mkilderne Corsair SF450 og Corsair RM650. I begge konfigurationer blev Noctua NH-U9S k\u00f8lesystemet brugt, men i det f\u00f8rste tilf\u00e6lde blev k\u00f8leribben installeret centralt, mens den i det andet tilf\u00e6lde blev flyttet mod den side, der genererede mere varme, i henhold til producentens anbefaling. <\/p>\n

Det bem\u00e6rkes, at i det andet tilf\u00e6lde blev termopastaen ikke fordelt j\u00e6vnt (p\u00e5 den ene side var laget tyndere), og der kan ikke udelukkes, at den anden fejl blev for\u00e5rsaget af forkert installation af k\u00f8leren. CPU Ryzen 9950X har et krav om varmeafledning p\u00e5 170 W (TDP, Thermal Design Power), mens det anvendte k\u00f8lesystem sikrede en varmeafledning p\u00e5 165 W. De manglende 5 W blev kompenseret af ekstra bl\u00e6sere i kabinettet og den lave temperatur i rummet, som var omkring 20\u00b0C. Begge processorer svigtede efter et par m\u00e5neders drift under h\u00f8j belastning. I projekts infrastrukturen anvendes der derimod allerede en anden server<\/a> i den samme konfiguration og med det samme belastningsniveau, og der opst\u00e5r ikke problemer med det.
