Ētahi atu te mau melo o te piha haapiiraa pūtea

I tua atu ki te "pou e toru" o te mākete ao, i runga i te pūtake o te maramara HD 7770 aroaro o ratou hua kamupene ingoa pērā i ASUS, MSI, Kikapaita, VTX, PowerColor me etahi atu. Na reira, karangatia te kaipānui te ki te whakatau poto ki o ratou hua.

O enei rama taa'eraa hua MSI. Ko te take i kua whakawhanakehia te kaiwhakanao kore anake te pūnaha tautauā kamupene mo te maramara hou, engari i hanga ano hoki etahi whakapainga i roto i te huānga PCB. Ko te hua ko tetahi o te utu tino i roto i te kāri pūtea motuhake. Ko te pūmanawa ki te titaria ona iti, engari i roto i te rite ki te whakairoiro rite mahi whāurutau muhu ore.

ASUS māngai iti rawa oti PCB AMD HD 7770, Heoi, kei te pai-mohiotia te pūnaha meangiti kamupene, te whakawa i nga arotake o tangata, ka whakaara ake te reira e rave rahi mau uiraa. Hei tauira, e kore e matau maha kaiwhakamahi te wera totohu whakapā ki te wāhanga poari taiawhio. I roto i te meka, haunga te GPU wera pūhiko e pängia ana me kōwae mahara, e hoki etahi take e kore e matao tōtika.

Na te aha e pā ana ki te tahi atu rama? Ratou tino arongia i roto i tenei arotake, no te mea te hua e whai AMD PCB me wiria noa ki reira he mātao, e taea whakauaua te tahi mea ki te ohorere i te kaihoko pea.

I roto i te mutunga

Ko te whāurutau ataata e hāngai ana i runga i te HD 7770 i AMD, te tuatahi o katoa koutou e taea e tūtohu e ki kaiwhakamahi katoa, te hunga e moe tākaro i roto i te mahi kēmu i ngā tautuhinga iti, me te reo i hanga ki te iti o te haumi. Haaputuraa i te moni ko kore anake te utu o te HD 7770 hua i roto i te mākete kāinga. nui te reira i te wāhi i konei nui, me te kāri ataata mana kohi iti e kore e rapua e te tangata nona o te aroaro mana supply kaha (450 Watts nui mo te rorohiko rite te katoa).

Kaua e wareware ki taua overclocking ko te taurangi anake e ka e taea ki te tau torutoru ki te whakapai ake i te mahi o nga whakaaro tawhitotia ki te oaoa i te kēmu hou i roto i te mākete rorohiko te kaiwhakamahi. e kore te kāri Video runga maramara AMD HD 7770 hangaia ki te mahi i roto i te whakaterenga tamau o te matua whakairoiro me kōwae mahara. Ki te hiahia koe i te mahi tika i roto i te aratau noa, kia utu koutou kanohi he mārama e kore i roto i te kōwae pūtea piha haapiiraa.
