GNU MP (GMP) teegi arendajad, mis pakuvad funktsioone, et teostada aritmeetilisi operatsioone keerukusega, on hoiatanud kasutajaid AMD Ryzen 9000 seeria Zen 5 mikroarhitektuuriga protsessorite korduva rikke kohta GMP teegi testimisel. \u00dcks arvatav p\u00f5hjus on protsessorite kahjustamine, mis on p\u00f5hjustatud \u00fclekuumenemisest, mis tekib GMP funktsioonide intensiivsel t\u00e4itmisel. Probleemi p\u00f5hjaliku anal\u00fc\u00fcsi l\u00f5puni ei soovitata kasutajatel aktiivselt GMP-d kasutada s\u00fcsteemides, kus on AMD Zen 5 CPU. <\/p>\n

Mured on seotud CPU AMD Ryzen 9950X (AMD Zen5 X16 4300MHz) korduva riknemisega, serveris<\/a> projektide testimisstruktuuris. Esimene rike juhtus 2025. aasta veebruaris, mille j\u00e4rel protsessor vahetati garantii alusel. Augusti l\u00f5pus juhtus olukord uuesti ja garantii alusel vahetatud CPU, mis oli installitud teise toiteploki ja emaplaadi s\u00fcsteemi, l\u00f5petas samuti t\u00f6\u00f6 samade \u00fclek\u00fctmise tunnustega (kiibil tekkis pleekinud ala, mille l\u00e4bim\u00f5\u00f5t on umbes 1 sentimeeter).

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

Esialgsete andmete kohaselt kasutab GMP teek liiga intensiivselt MULX-instruktsiooniga ts\u00fckleid, mis viib AMD Zen 5 s\u00fcsteemides energiatarbimise m\u00e4rkimisv\u00e4\u00e4rse suurenemiseni v\u00f5rreldes lubatuga ning jahutuss\u00fcsteemi, mis on valitud vastavalt spetsifikatsioonile, ei suuda kuumenemist kompenseerida. M\u00f5lema rikke ajal viidi l\u00e4bi test, kus k\u00e4sitsi kirjutatud assembleri ts\u00fcklid, mis koosnesid \u00fchest MULX-instruktsioonist, tekitasid maksimaalse koormuse. <\/p>\n

S\u00fcsteemides kasutati emaplaate Asus Prime B650M-K ja Asus Prime B650M-A WIFI II, samuti toiteplokke Corsair SF450 ja Corsair RM650. M\u00f5lemates konfiguratsioonides kasutati jahutuss\u00fcsteemi Noctua NH-U9S, kuid esimesel juhul oli radiaator paigaldatud keskele, teisel juhul aga tootja soovitusel nihutatud poole, kus soojus on tugevam. <\/p>\n

Teatatakse, et teisel juhul oli termopasta jaotatud eba\u00fchtlaselt (\u00fchel pool oli kiht \u00f5hem) ja t\u00e4ielikult ei saa v\u00e4listada, et teine rike oli p\u00f5hjustatud vale radiaatori paigaldamisest. CPU Ryzen 9950X puhul on teavitatud, et jahutusv\u00f5ime peab olema 170 W (TDP, Thermal Design Power), samas kui kasutatud jahutuss\u00fcsteem tagas jahutusv\u00f5ime 165 W. Puuduolevad 5 W kompenseeriti korpuse lisatuulikutega ja toas olnud madala temperatuuri abil, mis oli umbes 20\u00b0C. M\u00f5lemad protsessorid eba\u00f5nnestusid p\u00e4rast mitme kuu t\u00f6\u00f6tamist suure koormuse all. Samuti on projekti infrastruktuuris juba pikka aega kasutusel veel \u00fcks server<\/a> samas konfiguratsioonis ja sama koormuse tasemega, ning sellega ei teki probleeme.
