predpokladám že problém s pamäťou, čo myslíte ?

Můžeš ji zkusit vyměnit a otestovat, ale moc to na paměť nevypadá.

Dostal som chybne pc a zistit, v com je problem. Problem bol v RAM. Prejavovalo sa to tak, ze vzdy sa zhodila ina apka. A casto dosledkom bolo restart X servera (lebo ak poskodila nejaku kniznicu, casto GUI (lebo pamet prvkov na zobera dost pamete - v porovnani s inym vyuzivanim RAM), tak casto i s X (proste sa to zosype).

Ale co sa tyka hlasiek, tak podobny styl ako mas ty (ale bola iba jedna apka a potom sa zopisalo).

Memomy cack sa da zrobit lahko, tak sprav.

Jo, řekl bych, že to je možné. Paměť nebo něco po cestě.

• ECC to asi nemá?
• Ideální by bylo to vypnout a přes noc spustit memtest.
• Pokud si to nemůžeš dovolit, tak alespoň user-space program memtester.
• Taky pomůže spočítat hodněkrát po sobě MD5/SHA hash nějakého velkého souboru a dívat se, jestli vychází pořád stejně.

Nuž, medzi 369 sekundou od štartu a treťou hodinou po štarte ten systém nezaznamenal absolútne nič? To mi skôr pripadá ako nejako humorne nastavený power management v nejakom domácom ojazdenom multimediálnom centre ktorý zletel na cca 3 hodiny do sleep to ram pričom zdroj nemusel zareagovať dosť pružne. Čo je to za server, ako je starý, a je na rovnakej fáze ako elektrické vykurovanie?
