Ga masu kananan gine-gine da cewa son kafa da kansu Radeon HD 6870, da halaye na wannan katin ba zai iya wasa kadan ko ba rawa, idan sun kasance su iya gane a cikin shasi akalla 275 mm. By kanta, da 10-lokaci makirci da aka yi amfani da daidai domin tabbatar da mafi barga aiki na na'urar, kazalika da samar da masu amfani da ƙarin zaɓuɓɓuka cikin sharuddan graphics hanzari zuwa ga so darajar.

Ya kamata a sake a lura da cewa a cikin masana'antu tsari da wannan katin amfani na musamman aka gyara m Soja Class II misali, tare da abin da cimma iyakar karko, mafi ƙasƙanci yiwu dumama abinci, sarƙoƙi, kazalika da kyau kwarai m da kara amfani da na'urar.

A baya gefen na hukumar

Daban-daban haske Manuniya, located a kan Reverse gefen buga kewaye hukumar, damar musamman gani tantance yadda lodi graphics core, a matsayin stabilizer na da ikon samar da na'ura na samar da tsauri sharuddan sauyawa aiki zamani kamar yadda ya cancanta. Wannan ya sa ya yiwu gaba daya ya kashe ba dole ba manzilõli, a yayin da cewa akwai isasshe low matsa lamba a kan totur.

Ga kananan controls, ta hanyar da thermal ikon da aka kunna, kazalika da musamman GPU kariya, don tabbatar da aminci da na'urar lokacin da ake ji wani irin ƙarfin lantarki ne da muni. Hakika, wadannan ayyuka ne dace kawai don wani fairly kunkuntar kewayon kwararru ta amfani da kayayyakin aiki su kwantar da katin a kan aiwatar da "nitrogen" gwajin, don haka talakawa masu amfani ba da shawarar a ciyar da wasu tsanani gwaje-gwajen, wajen yin matsananci overclocking na'urorin da kawai stock mai sanyaya.

Har ila yau, kuma baya da gefen jirgin, a Bugu da kari ga ambata gyara, mai hawa katin mai sanyaya. Saboda haka, duk main abubuwa a Radeon HD 6870 da aka sake nazari sama, suna located a gaban gefe na PCB, game da shi, samar da mafi m sanyaya su.

haši

Sau da yawa barshi cikin Radeon HD 6870 reviews ne tabbatacce, kuma sau da yawa shi an haɗa ba kawai tare da abin da halaye da kuma kudin wani ba na'ura, amma kuma ya nuna gaskiyar cewa shi na samar da wani babban wadatattun tsarurrukan yawan dangane yiwuwa godiya ga nauyi na haši da kuma musamman adaftan.

Saboda haka, ana iya gani sau daya da connector for dangane da wata gada CrossFireX, dangane da wanda wani mai amfani iya lokaci guda hada biyu accelerators for kirga hadaddun graphics effects.

Bugu da kari ga misali PCI-Express bas, da katin kuma za a iya powered by biyu shida-pin connector located a gefe na katin. Ba da nisa daga gare su akwai irin ƙarfin lantarki ma'auni maki, kazalika da yanayin canji, wanda zai gudu mai sanyaya.
