Razvijetelji GNU MP (GMP) biblioteke, koja pru\u017ea funkcije za izvo\u0111enje aritmeti\u010dkih operacija s proizvoljnom to\u010dno\u0161\u0107u, upozorili su korisnike na incident s ponovnim otkazivanjem procesora serije AMD Ryzen 9000 temeljenom na mikroarhitekturi Zen 5 tijekom testiranja rada biblioteke. Pretpostavlja se da je o\u0161te\u0107enje procesora uzrokovano pregrijavanjem koje nastaje prilikom intenzivnog izvo\u0111enja GMP funkcija. Dok se ne zavr\u0161i potpuna analiza problema, korisnicima se ne preporu\u010duje aktivno kori\u0161tenje GMP-a na sustavima s CPU-om AMD Zen 5. <\/p>\n

Strahovi su izazvani ponovnim otkazivanjem CPU-a AMD Ryzen 9950X (AMD Zen5 X16 4300MHz) na serveru<\/a> testnoj infrastrukturi projekta. Prvo otkazivanje dogodilo se u velja\u010di 2025. godine, nakon \u010dega je procesor zamijenjen u okviru jamstva. Krajem kolovoza situacija se ponovila i zamijenjeni CPU, koji je instaliran u sustavu s drugom napajanjem i drugom mati\u010dnom plo\u010dom, tako\u0111er je prestao funkcionirati s istim znakovima koji ukazuju na pregrijavanje (na \u010dipu se stvorila obezbojena podru\u010dja promjera otprilike 1 centimetar).

\"Mogu\u0107e<\/center> <\/p>\n

Preliminarni podaci sugeriraju da biblioteka GMP previ\u0161e intenzivno koristi cikluse s uputom MULX, \u0161to dovodi do zna\u010dajno ve\u0107eg potro\u0161nje energije na sustavima s AMD Zen 5 nego \u0161to je navedeno te do nemogu\u0107nosti kompenzacije grijanja hladilnim sustavom odabranim u skladu sa specifikacijom. Tijekom oba o\u0161te\u0107enja izvr\u0161en je test s ru\u010dnim asemberskim ciklusima s jednom MULX uputom, koji stvara maksimalno optere\u0107enje. <\/p>\n

Na sustavima su kori\u0161tene mati\u010dne plo\u010de Asus Prime B650M-K i Asus Prime B650M-A WIFI II, kao i napajanja Corsair SF450 i Corsair RM650. U obje konfiguracije kori\u0161ten je hladnjak Noctua NH-U9S, ali je u prvom slu\u010daju hladnjak postavljen u centar, dok je u drugom prema preporuci proizvo\u0111a\u010da pomaknut prema strani s ve\u0107im grijanjem. <\/p>\n

Istaknuto je da u drugom slu\u010daju termalna pasta nije bila ravnomjerno raspore\u0111ena (s jedne strane sloj je bio tanji) i potpuno se ne isklju\u010duje mogu\u0107nost da je drugi kvar uzrokovan pogre\u0161nom instalacijom hladnjaka. CPU Ryzen 9950X ima deklariranu potrebu za hla\u0111enjem od 170 W (TDP, Thermal Design Power), dok je kori\u0161teni sustav hladjenja osiguravao hla\u0111enje od 165 W. Nedostaju\u0107ih 5 W nadokna\u0111eno je dodatnim ventilatorima unutar ku\u0107i\u0161ta i niskom temperaturom u prostoru, koja je iznosila oko 20 \u00b0C. Oba procesora su prestala raditi nakon nekoliko mjeseci pod optere\u0107enjem. U isto vrijeme, u infrastrukturi projekta za druge zadatke ve\u0107 du\u017ee vrijeme koristi se jo\u0161 jedan server<\/a> u istoj konfiguraciji i s istim razinama optere\u0107enja, i nema problema s njim.
