Dezvoltatorii bibliotecii GNU MP (GMP), care ofer\u0103 func\u021bii pentru efectuarea opera\u021biunilor aritmetice cu precizie arbitrar\u0103, au avertizat utilizatorii cu privire la un incident de defectare repetat\u0103 a procesoarelor din seria AMD Ryzen 9000, bazate pe microarhitectura Zen 5, \u00een timpul test\u0103rii func\u021bion\u0103rii bibliotecii. Se presupune c\u0103 deteriorarea procesoarelor a fost cauzat\u0103 de supra\u00eenc\u0103lzire, ap\u0103rut\u0103 \u00een urma execut\u0103rii intensive a func\u021biilor GMP. P\u00e2n\u0103 la finalizarea unei analize complete a problemei, utilizatorii nu sunt sf\u0103tui\u021bi s\u0103 foloseasc\u0103 activ GMP pe sistemele cu CPU AMD Zen 5. <\/p>\n

\u00cengrijor\u0103rile sunt cauzate de defectarea repetat\u0103 a CPU AMD Ryzen 9950X (AMD Zen5 X16 4300MHz) pe server<\/a> infrastructura de testare a proiectului. Prima defectare a avut loc \u00een februarie 2025, dup\u0103 care procesorul a fost \u00eenlocuit \u00een baza garan\u021biei. La sf\u00e2r\u0219itul lunii august, situa\u021bia s-a repetat \u0219i CPU-ul \u00eenlocuit \u00een baza garan\u021biei, instalat pe un sistem cu o alt\u0103 surs\u0103 de alimentare \u0219i o alt\u0103 plac\u0103 de baz\u0103, a \u00eencetat, de asemenea, s\u0103 mai func\u021bioneze cu acelea\u0219i semne care indicau supra\u00eenc\u0103lzirea (pe chip s-a format o zon\u0103 decolorat\u0103, cu un diametru de aproximativ 1 centimetru).

\"Posibil\u0103<\/center> <\/p>\n

Conform datelor preliminare, biblioteca GMP folose\u0219te cicluri cu instruc\u021biunea MULX prea intensiv, ceea ce duce pe sistemele cu AMD Zen 5 la un consum energetic semnificativ mai mare dec\u00e2t cel declarat, \u0219i la imposibilitatea de a compensa \u00eenc\u0103lzirea cu sistemul de r\u0103cire ales conform specifica\u021biei. \u00cen timpul ambelor deterior\u0103ri, a fost efectuat un test cu cicluri de asamblare manuale cu o singur\u0103 instruc\u021biune MULX, gener\u00e2nd o sarcin\u0103 maxim\u0103. <\/p>\n

Pe sisteme au fost folosite pl\u0103ci de baz\u0103 Asus Prime B650M-K \u0219i Asus Prime B650M-A WIFI II, precum \u0219i surse de alimentare Corsair SF450 \u0219i Corsair RM650. \u00cen ambele configura\u021bii a fost utilizat un sistem de r\u0103cire Noctua NH-U9S, dar \u00een primul caz radiatorul a fost instalat central, iar \u00een al doilea, conform recomand\u0103rii fabricantului, a fost deplasat spre partea cu \u00eenc\u0103lzire mai mare. <\/p>\n

Se observ\u0103 c\u0103 \u00een al doilea caz, pasta termoconductoare a fost distribuit\u0103 neuniform (pe o parte, stratul a fost mai sub\u021bire) \u0219i nu se exclude complet c\u0103 a doua defec\u021biune a fost cauzat\u0103 de o instalare incorect\u0103 a radiatorului. Procesorul CPU Ryzen 9950X are un TDP (Thermal Design Power) declarat de 170 W, iar sistemul de r\u0103cire utilizat asigura un transfer termic de 165 W. Cei 5 W lips\u0103 au fost compensa\u021bi cu ventilatoare suplimentare \u00een carcas\u0103 \u0219i o temperatur\u0103 sc\u0103zut\u0103 \u00een camer\u0103, care se \u00eencadra \u00een jurul valorii de 20\u00b0C. Ambele procesoare s-au defectat dup\u0103 c\u00e2teva luni de func\u021bionare la sarcin\u0103 mare. \u00cen infrastructura proiectului, pentru alte sarcini, un alt procesor este utilizat de mult timp, serverul<\/a> \u00een aceea\u0219i configura\u021bie \u0219i cu acela\u0219i nivel de sarcin\u0103, f\u0103r\u0103 a avea probleme.
