Isiqophi ezingavamile ekhaya

Cishe, akunakwenzeka ukuba abalandeli imidlalo yama-computer yesimanje yinto ukujabulisa ngaphezu entsha leyehlukene ihluzo ikhadi, okuyinto has a high amandla ama. Isizathu salokhu itholakala lokuthi ukuthi onjiniyela umdlalo ukukhulula ngaphezulu isisetshenziswa khudlwana ihluzo isicelo adaptha, kanjalo babangele isithakazelo kule nkampani NVIDIA imikhiqizo AMD (phambilini obuwaziwa ngo ATI), kuleli uhla babe ihluzo amakhadi enamandla. Nokho, lolu lwazi akunakwenzeka ukuba akumangalisi muntu: emashalofini computer nje "waqala ukugcwala" onobuhle ezahlukene izixazululo kusukela AMD NVIDIA - njengoba isisho, yonke ukunambitheka kanye nesabelomali.

Uma senza ngokwengqondo uhambo kweminyaka eyishumi emuva ngesikhathi bese ubuza abadlala sendlela ukhethe ikhadi eliphezulu ohlelweni lwakhe amageyimu, impendulo uzonikezwa uvivinyo ezifanele kanye nokubuyekeza ku-intanethi. Wawunodonga ukubaluleka inani yamapayipi, inqubo ubuchwepheshe, ukubanda, umsindo ezingeni namanye izici. Kwathi ngesikhathi isitatimende ukuthi emva ukuthenga iminyaka 1-2, kungase kudingeke ukuba prozharka ividiyo - akekho ukholwe, ucabangela la mazwi njengengxenye ihlaya. Maye, njengoba kuvamisile, ngokoqobo kuye kwanyatheliswa kokuqagela lalinamandla. Manje prozharka ikhadi ividiyo - kuba ezijwayele ngendlela eziningi ukuze alulame kudivayisi ... Kodwa ake zonke ukuze.

Isici esiyinhloko lanoma iyiphi ividiyo - Ihluzo processor. Lokhu chip esikhulu kakhulu ihlanganiswe izingxenye izingxenye zalo electronic. Ngokuvamile kuba kurediyetha lensimbi fan kurediyetha noma ukushisa ipayipi (esimweni Ukupholisa yokwenziwa). Nokho, wonke chip - akuyona processor. Ingxenye esemqoka nengaphakathi okuthiwa, bagxila encane emnyama sikwele-chip posted on textolite isisekelo. It adjoins kurediyetha. Crystal kuyinto chip ne sebuningini umlenze-lead soldered ezihlalweni ku base enkantolo textolite. Laba oxhumana, kakhulu kangangokuba okwesikhathi eside isikhathi nokunamathisela ngomthofu wenziwa ku ezenzakalelayo inhlangano imigqa. Ngezinye contact ngamunye ibholo solder, okuyinto elicibilikile, uxhuma emlenzeni chip ndawo. Kodwa kanjani konke okungenhla ahlobene prozharka isiqophi? Ukuxhumana ngqo.

Ekuqaleni kuka-2005, abanikazi abaningi NVIDIA ihluzo amakhadi aqala ukukhonona ukuthi amakhadi ngaphandle kwesizathu kuyekile ukusebenza. Izimpawu zihlukene: Amabha noma izikwele esikrinini; ukungakwazi ukufaka umshayeli; Siphela kanjalo isikhathi sokuphumula kwimodi 3D, kanjalonjalo. Khona-ke, kwakukhona imibiko nezinkinga ezifanayo ne-AMD imikhiqizo, nakuba "ubuholi" Ngaphezu kwakho koke, wayevela NVIDIA. Bhala off bonke kuya "intukuthelo hot" kumadivayisi kwakungenakwenzeka njalo, ngakho-ke, wasikisela ukuba wonke iphuzu yonke engaphelele nokunamathisela ngomthofu chip ekhadini ihluzo. Nokho, ngo-2008 i-NVIDIA neyaziwayo abampofu izinga solder ... esikhaleni phakathi chip kanye substrate chip, okungukuthi, isici sangaphakathi. Abanye oxhumana solder ibhola kungenzeka ukuthi ingabi khona ngokuphelele, ngakho ngenxa yemvelo namachibi ukumelana akulezi zindawo luyanda, okuholela izinkinga ezaziwayo. Ngakolunye brazing kwaba engaphelele ngenxa lemali enganele solder.

isiqophi ezingavamile - lena ngenye yezindlela ukuzama ukubuyela ikhadi okuyiphutha "ukuphila." Kuyadingeka ukuba asuse ngokucophelela yonke uhlelo Ukupholisa ngomoya, futhi izingxenye plastic, nezixhumi futhi capacitors electrolytic ucwecwe ukugoqa. Beka ihluzo ikhadi kuhhavini phezu Kwe-dielectric Heating base chip phezulu. Nika amandla Ukushisa ukuze 200-230 degrees. Kule modi, ikhadi efudumele 20 imizuzwana. Cisha kuhhavini kancane (!) Wavula umnyango ukuhlela Ukupholisa kancane kancane.

Ngemva ikhadi ezifana operation ungenza. Isikhathi sokuphila kwayo ngemuva lokhu ezinsukwini ezimbalwa iminyaka engu 2-3.
