Namuhla sibheka ukubambezeleka yimemori. Kuyini futhi kungani lesi sici edingekayo ubuchwepheshe bama-computer? Lapho kutholakala ukusetshenziswa kwawo? Indlela yokufeza ukubaluleka best of lesi sici?
mayelana RAM
Ngakho sikubiza idivayisi ekhethekile, equkethe idatha futhi ezenziwe egijima ngenkathi izinqubo ikhompyutha. Ngenxa ijubane isinyathelo yayo, izenzo njengenhlangano phakathi ulwazi etholakala kwi-hard disk, futhi processor. I kuyaqondakala kakhulu abantu abaningi isici inani RAM. Kulokhu, egijima umthetho ukuthi eside kangakanani, ngcono kithi. Empeleni manje ukusebenzisa i-Inthanethi, ubuke ama-movie sisebenze iningi izinhlelo ewusizo ulahlekile 2GB. Kodwa ukuhlolwa ukusebenza isetshenziswa, futhi eziningi nezinye nemingcele, ezifana imvamisa. Ikhombisa ingakanani idatha angadluliselwa phezu ibhasi per unit isikhathi. I emikhulu imvamisa, ayanda izinga ulwazi. Kodwa uqaphele ukuthi busekelwa CPU kanye umbadlana. Noma ake okunye ukukhetha, akunjalo owaziwa - ukungaphumeleli. Ngakho ngokuthi ukubambezeleka nesikhathi amasignali lapho zivela okungahleliwe ukufinyelela inkumbulo. I-computer ukusebenza kancane eziyosebenza, kube nomphumela omuhle kakhulu ngokuya kahle ngokuhamba kwesikhathi vela.
Izici ukungaphumeleli
Esigabeni esandulele, kulahleke isikhathi esisodwa esibalulekile. Kanye imvamisa ukubaluleka RAM uyanda futhi uya ngokuya RAM ukungaphumeleli. Yini engcono ke ukuba ukwehlukaniswa iziqephu? Indlela ukukhetha izinkomba ucishe jikelele? Kubhekwe sokusebenzisa ngokuyimpumelelo onobuhle eziningana inkumbulo. Ngakho, uma kukhona ezimbili, futhi usebenza kwimodi ezimbili-siteshi, lo ijubane ukudluliswa kwedatha izokwenyuka. Ukuze wenze lokhu, wasebenzisa ibhodi kumele ukufakwa Slots ezithile (okuyinto ngokuvamile zabelwe ngombala owodwa). Lapha kukhona sici: akudingekile ukuthi kwakunokuningi okwakumelwe esilinganayo inkumbulo. Kodwa maqondana imvamisa, kuyinto efiselekayo lapha ukuze uthole ngengozi ephelele. Kungenjalo bazosebenza anenani ezijulileyo ezimbili.
Kuyini inkumbulo ukungaphumeleli
A theory kancane. Ngakho ngokuthi summation Kwenziwa usebenzisa Coefficient ekhethekile nengaphethwe imisinga reverse transistors ukuthi zifakwe ulayini imemori chip esetshenziswa ngamunye, futhi ngesikhathi ukushintsha. Kungase kubonakale xaka, kodwa nokucabanga okungamanga. Ngakho, ukubambezeleka incike nobuningi chips ukusebenza. Into ezithakazelisayo wukuthi akusiyo ngokulingana. Ngamanye amazwi: the ephansi ubambezelo, ngcono umsebenzisi. Ake sibheke isibonelo. Sifuna ukuba kwethu yezinto inkumbulo computer yayilingana gigabytes ezimbili. Singathembela umugqa owodwa, okuyinto uyosinika 2GB. Kodwa lena akuyona indlela engcono. Kulokhu, kungcono ufake imigqa emine, ngamunye ne-512 MB. Kufanele futhi acabangele umthelela umbadlana, kanye nezinhlobo RAM ukusetshenziswa. Module amisiwe ngesisekelo ubuchwepheshe obufanayo, awukwazi oluzobhekelela ukuthi yakhelwe ubuchwepheshe ezahlukene. Lokhu kwenziwa ukuze kuvinjelwe umonakalo ngesikhatsi operation indlela izimo okungahlosiwe ezinjalo.
ukuqokwa
Uma uke wabheka kudivayisi, ungase ubone into efana lokhu okulandelayo: "I-RAM ukubambezeleka: CL9". Kusho ukuthini? Lesi sibalo kukhombisa ukubambezeleka athize kwenzeka phakathi ekuqaleni ukuthumela ikheli ikholomu imemori futhi, ngokulandelana, langempela ukudluliswa kwedatha. Digital equkethe lisho ukubaluleka ezidingekayo ukuze kuqale inqubo. Zincane kangaka, ngcono kithi. Ngakho-ke njalo kunesidingo ukucabangela lesi silinganiso lapho ukhetha inkumbulo.
izinhlobo amadivayisi
Ithuba ngokuhlukana isebenzisa double idatha isilinganiso (DDR), okungase elihunyushwe njengoba double idatha isilinganiso. Izibonelo zokuqala kwalezi zinto zobuchwepheshe kuye 184 contact. voltage yabo ejwayelekile kwaba 2.5 V fetches idatha ye 2 izingcezu ngemjikeleto ngamunye. Kodwa esikhathini sethu, basuke kubhekwe akusebenzi futhi manje cishe noma kuphi futhi kunoma iyiphi izimo esetshenziswa. zanamuhla futhi kubhekwa DDR2 ezivamile. It ikuvumela ukuthi ukhethe ilungelo 4 izingcezu ngomjikelezo iwashi. I module yakhelwe njengoba ephrintiwe wesifunda ibhodi, okuyinto has 240 izikhonkwane (120 ohlangothini ngalunye). Izinga supply voltage ngoba 1.8V kubhekwa DDR3 empeleni esasisesisha. He isinyathelo esisodwa ungakwazi lakhetsiwe ku 8 izingcezu idatha ukwenza. Wenza ebhodini wesifunda, has 230 izikhonkwane. Kodwa standard supply voltage kulokhu kuphela 1.5 V Kukhona futhi kakhudlwana futhi DDR4, kodwa lobu buchwepheshe obusha, okuyinto namanje nzima kakhulu ukuhlangabezana.
umthamo
Kakade siqeda i-athikili mayelana ukubambezeleka yimemori. Okuye ibike, kwanele ukuba baqonde omningi walo ulwazi OP. Futhi uqedele - ubungako bokudlulisa. Ngakho, kuhle, kusukela inkumbulo ukubaluleka lesi sici kufanele zifane usayizi ipharamitha processor. Cabanga ngalo mbuzo, ucabangela ukuthi siye eshiwo ngaphambili imodi embaxambili-siteshi. Sine processor ukuthi umthamo - 10.600 MB / s. Sabe Ungasetha module RAM, izimfanelo okuzoba 5.300 MB / s. Ngohlelo, bayoba ukunikeza umthamo ofanayo-bandwidth. Kodwa ungakhohlwa ukuthi amamojuli kumele imvamisa efanayo. Futhi okungcono wukuthi nabo babe umthamo ofanayo, ababezikhiqiza nomkhiqizi eyodwa futhi akhiqizwa batch olulodwa. Khona-ke lo ukubambezeleka inkumbulo azothanda esiphansi Inani kungenzeka. Uma sikhuluma imodi embaxambili-siteshi, ke ngokuqondile lezi zenzakalo ukuthengisa Kit. Lokho okubizwa ngokuthi i amasethi ekhethekile ukuthi elungiselelwe umsebenzi kakade. Kufanele kuqashelwe ukuthi kungenzeka ukusebenzisa imemori futhi kabani komkhawulokudonsa kunaleyo processor. Kodwa ukubambezeleka akuyona kakhulu abathintekayo, ngisho noma umehluko iphindaphindeke.
isiphetho
Njengoba ubona, the ukubambezeleka memory - lena isici esibalulekile kakhulu. Ikakhulukazi olumnandi Kuyaphawuleka ukuthi ingathinta hhayi kuphela ohlangothini hardware, kodwa futhi ngiphakamisa ukucushwa yekhompyutha yakho. Kodwa-ke, kusadingeka ukuba uyigcine ngaphakathi ezinengqondo futhi ezingaphezu kuka-Quad imodi akusebenzi. Cha, yebo, uma uthanda, ungakwazi futhi amakhadi inkumbulo 512 MB ukwakha lwekhompyutha olungase ngizibonge isivinini ukucutshungulwa 8 GB. Kodwa ukusebenza kwe uthathe leso sinyathelo kungaba kunalokho ezingabazisayo. Kungcono ukuhlala kuleli cala 4 amabhodi, ngamunye okuzodingeka 2GB.
