GNU MP (GMP) teegi arendajad, mis pakub funktsioone aritmeetiliste operatsioonide teostamiseks suvalise t\u00e4psusega, on hoiatanud kasutajaid AMD Ryzen 9000 seeria Zen 5 mikroarhitektuuriga protsessorite korduvate rikete kohta GMP teegi t\u00f6\u00f6testimise k\u00e4igus. Eeldatakse, et protsessorite kahjustus on tingitud \u00fclekuumenemisest, mis tekib GMP funktsioonide intensiivse t\u00e4itmise ajal. Enne probleemi t\u00e4ielikku anal\u00fc\u00fcsi ei soovitata kasutajatel aktiivselt kasutada GMP-d AMD Zen 5 protsessoritega s\u00fcsteemides. <\/p>\n

Mure on tekkinud AMD Ryzen 9950X (AMD Zen5 X16 4300MHz) protsessori korduvate rikete t\u00f5ttu serveril<\/a> projekti testimis infrastruktuuris. Esimene rike toimus veebruaris 2025, p\u00e4rast mida asendati protsessor garantiiga. Augvisi l\u00f5pus kordus olukord ja garantiiga asendatud protsessor, mis oli paigaldatud teise toitebloki ja emaplaadi alla, lakkas samuti t\u00f6\u00f6tamast samade \u00fclekuumenemise tunnustega (kiibil tekkis pleekinud ala, mille diameeter on umbes 1 sentimeeter).

\"V\u00f5imalik<\/center> <\/p>\n

Esialgsete andmete kohaselt kasutab GMP teek liiga intensiivselt MULX k\u00e4ske, mis toob kaasa AMD Zen 5 s\u00fcsteemidesse oluliselt suurema energia tarbimise kui v\u00e4idetakse, ning ei suuda jahutuss\u00fcsteem, mis on valitud vastavalt spetsifikatsioonile, soojust kompenseerida. M\u00f5lema kahjustuse ajal viidi l\u00e4bi test k\u00e4sitsi koostatud assemblerits\u00fcklitega, millel oli \u00fcks MULX k\u00e4sk, genereerides maksimaalse koormuse. <\/p>\n

S\u00fcsteemides kasutati emaplaate Asus Prime B650M-K ja Asus Prime B650M-A WIFI II, samuti toiteallikaid Corsair SF450 ja Corsair RM650. M\u00f5lemas konfiguratsioonis kasutati jahutuss\u00fcsteemi Noctua NH-U9S, kuid esimeses juhul oli radiaator paigaldatud keskele, samas kui teises, tootja soovituste kohaselt, nihutati see poole suurema soojuse suunas. <\/p>\n

On m\u00e4rgatud, et teisel juhul oli termopasta jaotatud eba\u00fchtlaselt (\u00fchel k\u00fcljel oli kiht \u00f5hem) ja v\u00e4listada ei saa, et teise rikke p\u00f5hjuseks oli radiaatori vale paigaldamine. CPU Ryzen 9950X puhul on vaja jahutust 170 W (TDP, Thermal Design Power), samas kui kasutatav jahutuss\u00fcsteem tagas jahutuse 165 W. Puuduolevad 5 W kompenseeriti korpusesse paigaldatud lisaventilaatoritega ja madala toatemperatuuriga, mis oli umbes 20\u00b0C. M\u00f5lemad protsessorid eba\u00f5nnestusid mitme kuu p\u00e4rast k\u00f5rge koormuse all. Samas on projektis muude \u00fclesannete jaoks juba pikka aega kasutatud veel \u00fchte server<\/a> samas konfiguratsioonis ja sama koormuse tasemega ning probleeme ei esine.
