AMD zistila príčinu tepelného poškodzovania Ryzenov 7000, vydala upravený BIOS

Značky: AMDZen / RyzenCPU

DSL.sk, 27.4.2023


Spoločnosť AMD identifikovala hlavnú príčinu spôsobujúcu v niektorých prípadoch extrémne zahrievanie poslednej generácie desktopových procesorov AMD Ryzen 7000 vyúsťujúce do tepelného poškodenia a vydala novú verziu softvéru AGESA zabraňujúcu týmto problémom, ktorú výrobcovia dosiek zahrnú teraz do svojich BIOS-ov.

Spoločnosť o tom informovala v stanovisku poskytnutom hardvérovým serverom, napríklad Anandtechu.

Stanovisko detailne nepopisuje všetky uskutočnené opatrenia. Avizuje ale uskutočnenie opatrení v napájaní na AM5 doskách, ktoré zabránia používaniu CPU mimo limitov špecifikácie, a uvádza jedno konkrétne opatrenie, limitovanie pracovného SoC napätie procesora na maximálne 1.3 Volta.

AMD tak čiastočne potvrdila skoršie neoficiálne informácie, podľa ktorých sa problémy môžu vyskytnúť práve pri SoC napätí minimálne 1.4 Volta po manuálnom zvýšení alebo aktivovaní EXPO profilu pamätí. Podľa skorších neoficiálnych informácií sa najskôr poškodia tepelné senzory a tým sa znefunkční ochrana proti prehriatiu, tieto informácie stanovisko neuvádza.

Ako sme upozornili, užívatelia sa na problémy sťažujú najmä v poslednom čase a v prípade modelov 7000X3D s veľkou L3 cache, problémy sa vyskytujú ale aj pri ostatných modeloch Ryzen 7000. Okrem procesora môže prísť aj k poškodeniu dosky.

K problémom môže prichádzať po manuálnom pretaktovaní ale tiež po zapnutí profilov pamätí technológie EXPO. Technológia EXPO, Extended Profiles for Overclocking, je technológiou oficiálne podporovanou AMD, výrobcami dosiek a pamätí, ktorá umožňuje aktivovaním EXPO profilu zvýšiť takt pamätí. Po zapnutí EXPO profilu sa pre stabilný beh ale typicky automaticky zvyšuje aj pracovné SoC napätie procesora.

Hoci EXPO je oficiálne podporované automatické pretaktovanie pamätí, podľa Tom's Hardware sa na poškodenie procesorov pri zapnutí EXPO nevzťahuje záruka. V aktuálnom stanovisku AMD odporúča užívateľom, u ktorých sa vyskytol tento problém, aby kontaktovali podporu spoločnosti.

Novú verziu AGESA spoločnosť už poskytla výrobcom dosiek a vydanie nových verzií BIOS-ov očakáva AMD v nasledujúcich dňoch. AMD odporúča všetkým užívateľom, aby si na AM5 doskách následne BIOS aktualizovali.

Uskutočnené opatrenia podľa AMD nemenia možnosti pretaktovania pamätí pomocou EXPO alebo XMP alebo zvýšenie výkonu pomocou PBO technológie.

Ak si vezmeme Apple za prikladnu firmu (nie v zmysle dobra, spravna ci 1tky na ZS), tak pravo na opravu ma velmi dobry zamer. Horsie to je uz s definiciou a praxou. Preco pri tvorbe zakonov neparticipuju osoby ako vecne negativne naladeny L. Rossman?

Tak potom nech prestanu udavat pri ramkach frekvenciu prave pri aktivovanom expo. Kolko krat si clovek kupi napriklad 3600 MHz pamete, ktore su ale defaultne 2800, alebo i menej.

To je všetko tak trochu marketing výrobcov RAM.

Napr. ako 2133MHz CL11 DDR3 RAM, no oficiálne procáky podporovali (garantovali podporu) pre 1066 či 1333 MHz (už presne nepamätám. Dosky uvádzali aj viac, do aleluja. Kľúčová je vždy podpora procesorom.

Toto uvádza AMD pre 7800X3D:
Max Memory Speed
2x1R DDR5-5200
2x2R DDR5-5200
4x1R DDR5-3600
4x2R DDR5-3600

Intel uvádza pre i9-13900K:
Memory Types
Up to DDR5 5600 MT/s
Up to DDR4 3200 MT/s

Toto sú garantované frekvencie. Ostatné ber tak, že ide o OC. Ak predáva Kingston 1800 MHz DDR3 RAM, je to už OC.

Súhlasím ale s Tebou, že je to na uváženie.

Žiadne EXPO a XMP som nikdy nemusel používať. Proste nastavím manuálne frekvenciu, časovanie a napätie podľa OC profilu (vyčítaš zo specsheet výrobcu alebo cez CPU-Z). Minúta nastavovania. Potom máš istotu, že do ničoho iného nestrkáš nos. Celý život to takto robím a nikdy nebol problém.

A z akého dôvodu to nastavuješ na vyšiie niečo, než na aké je to normálne stavané? Aj do žiarovky doma púšťaš 250V namiesto 230V či ako?
Odpovedať Známka: -4.3 Hodnotiť:
 

Ono je to stavané na viac ako si myslíš. Preto máš nejaké minimum, ktoré musí dať všetko, a nejaké optimum, čo niektoré dávajú a iné nie.
A o tom to je. Či chcem minimum, optimum, alebo maximum za svoje peniaze

Tvoj príklad je z tohto dôvodu na holý kokot.

veď výrobca RAMiek Ti predáva 6000 MHz DDR5 RAMky, no sú to priamo ním OCnuté 5200ky trebárs

každá RAMka podporuje niekoľko JEDEC režimov a väčšinou 1-2 OC režimy. to OC sú to, čo predáva tie karty, teda rozdielnosť čipov, každý zvláda niečo iné, potom sa pozbierajú podobné a pretaktujú od výroby viac, predáva sa to potom drahšie

a ak nastavíš tieto OC parametre manuálne v biose, tak vlastneš spravíš to isté ako by si zapol Expo, ale zmeníš len to čo ty chceš, máš to pod kontrolou

Príčinou je to, že výrobcovia dosiek prebrali napájacie limity pre X3D CPU z tých non-X3D CPU a problém bol na svete. Zatiaľ čo 7600X/7800X/7900X a ostatné bez 3D cache s napätím SoC vyšším ako 1.4V problém nemajú, pre modely s 3D cache je to otázkou života a smrti.

AMD limity neuzamklo v AGESE. To ale neznamená, že keď výrobca dosiek mení niečo, čo defaultne nie je uzamknuté, je inak v poriadku.

AMD v stanovisku uvádza, že EXPO a PBO budú plne využiteľné aj s uzamknutým SoC napätím na 1.3V. Otázkou zostáva, na kerú riť SoC napätie bolo vôbec zvyšované, keď to prakticky nemá význam ...
