Dotaz: Ryzen HW bug

[majales]

Zdravím, Jen by mě zajímal jak vlastně AMD vyřešilo ten Ryzen HW Bug, protože se zdá že se znovu objevuje..

Řešil někdo z vás výměnu procesoru přímo u AMD?

Můj Ryzen 5 1600, ze 41 týdne (UA1741SUS), test kill-ryzen (https://github.com/suaefar/ryzen-test) - Deska ASUS PRIME B350-PLUS, BIOS 1002 09/29/2017, RAM 16GB (2x8GB) 2400MHZ

Tak zpět.. Byla to moje chyba. Originální kill-ryzen.sh je pouze pro ubuntu 17.04, pod 17.10 se z kvůli nějakému konfliktu gcc-7.1.0 nezkompiluje a vyhodí chybu. Upravil jsem kill-ryzen.sh skripty a změnil to na gcc-7.2.0. Kompilace běžela více jak 1h 30m bez problému.

Není 1:30 málo? Jsem měl za to, že to muselo běžet tak týden.

BTW chybnej ryzen by ti měli vyměnit, pokud máš ten s chybou a při výměně poukážeš na to že si shazuje kompilaci.

Jestli tu chybu opravili vydáním novýho firmware to si nejsem jistý.

[majales]

Podle reportu to shazovalo spolehlivě ty Ryzeny s HW bugem do 10 minut.. pravda mohl jsem to nechat běžet déle.. ještě to vyzkouším.

[pc2005]

S vypnutým SMT byl ten čas delší. Ale myslím, že mám tu časovou informaci z nějakého původního testu nebo přímo z reálné kompilace v gentoo.

Jinak použitý ryzen je podle phoronixu asi OK.

it appears to affect Ryzen CPUs manufactured prior to week 25

[Lukáš Zapletal]

Opatchoval jsem mu (autorovi kill-ryzen.sh skriptu) Fedoru, na jakým distru to nejde?

Každopádně já jsem měl kus co padal po 5 minutách, po 10 dnech se supportem a 25 dnech bez CPU mi poslali novej, kterej jede jak má. Ale SMT mám zatím vypnutý, nechci laborovat je to můj pracovní stroj a 8 vláken mi stačí.

[Vladimír Čunát]

To jste tedy šel přes klasický reklamační proces u prodejce? Já jsem dlouho doufal ve vyřešení microcodem, ale zřejmě marně.
