Se presume que el da\u00f1o a los procesadores fue causado por el sobrecalentamiento que ocurre al ejecutar intensamente las funciones de GMP. Hasta que se complete un an\u00e1lisis completo del problema, no se recomienda a los usuarios utilizar activamente GMP en sistemas con CPU AMD Zen 5.    <\/p>\n<p>Las preocupaciones est\u00e1n relacionadas con el fallo recurrente de la CPU AMD Ryzen 9950X (AMD Zen5 X16 4300MHz) en <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/server\/dts-newyork\/\"   title=\"servidor\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2824\">servidor<\/a> la infraestructura de prueba del proyecto. El primer fallo ocurri\u00f3 en febrero de 2025, tras lo cual la CPU fue reemplazada bajo garant\u00eda. A finales de agosto, la situaci\u00f3n se repiti\u00f3 y la CPU reemplazada bajo garant\u00eda, instalada en un sistema con otra fuente de alimentaci\u00f3n y otra placa base, tambi\u00e9n dej\u00f3 de funcionar con los mismos s\u00edntomas que indicaban sobrecalentamiento (se form\u00f3 un \u00e1rea descolorida en el chip, de aproximadamente 1 cent\u00edmetro de di\u00e1metro).     <center><img decoding=\"async\" alt=\"Posible da\u00f1o en la CPU AMD Zen 5 al usar la biblioteca GNU MP\" src=\"\/wp-content\/uploads\/2025\/08\/8e4062192dba7c057c2afdfc07fabb34.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>    <\/p>\n<p>Seg\u00fan datos preliminares, la biblioteca GMP utiliza ciclos con la instrucci\u00f3n MULX de manera demasiado intensa, lo que causa en sistemas con AMD Zen 5 un consumo de energ\u00eda significativamente mayor de lo declarado, y la incapacidad de compensar el calor con el sistema de refrigeraci\u00f3n seleccionado de acuerdo con las especificaciones. Durante ambos fallos, se realiz\u00f3 una prueba con ciclos assembler manuales con una instrucci\u00f3n MULX, que gener\u00f3 la m\u00e1xima carga.     <\/p>\n<p>En los sistemas se utilizaron placas base Asus Prime B650M-K y Asus Prime B650M-A WIFI II, as\u00ed como fuentes de alimentaci\u00f3n Corsair SF450 y Corsair RM650. En ambas configuraciones se utiliz\u00f3 un sistema de refrigeraci\u00f3n Noctua NH-U9S, pero en el primer caso el radiador se instal\u00f3 en el centro, mientras que en el segundo, seg\u00fan la recomendaci\u00f3n del fabricante, se desplaz\u00f3 hacia el lado con mayor calentamiento.     <\/p>\n<p>Se observa que en el segundo caso, la pasta t\u00e9rmica no estaba distribuida uniformemente (en un lado la capa era m\u00e1s delgada) y no se puede descartar completamente que la segunda falla fue causada por una instalaci\u00f3n incorrecta del radiador. El CPU Ryzen 9950X tiene una necesidad de disipaci\u00f3n de 170 vatios (TDP, Potencia de Dise\u00f1o T\u00e9rmico), mientras que el sistema de refrigeraci\u00f3n utilizado proporcionaba una disipaci\u00f3n de 165 vatios. Los 5 vatios faltantes se compensaron con ventiladores adicionales en la carcasa y una baja temperatura en la habitaci\u00f3n, que era de aproximadamente 20\u00b0C. Ambos procesadores fallaron despu\u00e9s de unos meses de operaci\u00f3n a alta carga.
