    Kupiłem niedawno kartę graficzną Radeon HD X2600XT AGP posiadającą 512 mb pamięci i 128 bit. No i gdy zauważyłem że coś jest nie tak z chłodzeniem bo gdy grafika się nagrzała w grze wyłączał się monitor i dawało go dary później włączyć (teraz już to rzadko występuje). Włączyłem Everesta i tam pisało, że karta ma 256 mb i 64 bit. Ja od razu na stronę PowerColour (tylko z tej firmy ta karta wyszla na 512 mb) i tam nic nie pisalo o tym że karta ma coś w stylu TurboCache. Popatrzyłem po forach i szukałem o tej karcie. Znalazłem gościa co w GPU-Z wykrywało mu normalnie 512mb/128bit. Próbowałem sterowniki ten co on mial i nic. Wyjąłem kartę i tam pisalo ze ma ona 512 mb i ilość kostek pamięci się zgadzała.

    Kartę kupiłeś używaną z Allegro ?
    Co u Ciebie pokazuje GPU-Z ?

    Kupiłem nową ze sklepu. I GPU-Z pokazuje dokładnie to samo co Everest. Ja przypuszczałem, że może mam za wolne złącze AGP na płycie głównej bo gościu z tego GPU-Z mial AGP 8x na plycie głownej a ja mam AGP 4x na plycie glownej.

    Proszę poszukac porady w supporcie oraz na forum producenta tego systemu operacyjnego. Temat zamykam.
