Ucuphe ixesha, inkumbulo kunye nokusebenza PC

maxa wambi lwesigama ikhompyutha uxabela xa iyonke. Ngenxa yoku, umsebenzisi kwaye ngexesha elinye umthengi lokugqibela ujongene neengxaki ezithile yokuzikhethela xa uthenga ikhompyutha okanye uhlaziye lwesimo zayo. Ukuze enye yeempawu lubalulekileyo PC na ekuthiwa-ixesha. RAM iphawulwa njenge parameter kwamaza, esebenza kuwo kwakunye ubungakanani ukulibaziseka unyango nezinye iimodyuli ze-computer.

Ngaphambi kokuba siphendule lo mbuzo yintoni na ixesha, sichaza lo mgaqo esisiseko RAM - imemori yofikelelo oluzenzekelayo.

ntoni "yemvu" Indlela

imemori yofikelelo oluzenzekelayo (RAM, RAM) - yenye yeyona ibalulekileyo yayo nayiphi na ikhompyutha. Igcina okwethutyana iinkcukacha eziyimfuneko ukulungiselela ukusebenza kumqhubekekisi. Le transfer ulwazi kule meko yenzeka ngqo unit yokugcina kwi isiqalo okanye kwimemori ekhethekileyo ultra-fast. Ngamagama alula, inkumbulo - a IMicrochips ezimbalwa ukugcina ulwazi kuzo zonke iinkqubo yomsebenzisi aphilileyo. Kodwa ngaba akukwazeki ukuba ukugcina yonke kwi hard drive yakho, loo nto kwakhona inkumbulo? Ngelishwa hayi. yonke Ingongoma ngesantya nokuthembeka. I-hard drive Idiski sisixhobo ngoomatshini kunye ngesantya esisezantsi yokusebenza (xa kuthelekiswa iimfuno CPU) kunye anezibonelelo ezimbalwa. RAM akanawo ezi neengxaki, oko ngokukhawuleza, yaye ubomi yawo ixhomekeke kwinani hits.

ngezigaba

Kukho iindidi ezimbini memory zezi:

• SRAM - uhlobo RAM static;
• DRAM - inamandla uhlobo RAM.

Ngaphandle lwaya emazweni onke iimpawu zobugcisa ekuqondeni SRAM-memory kunokuthiwa imicwe ezinjalo ukuzila. Kwaye ukulibaziseka ukudluliselwa data kwibhloko RAM kwenzeka ngoko nangoko. Ngelishwa, iindleko eziphezulu impumezo loo eyahlukileyo. Ukongeza, ivolyum kwimodyuli memory zimiselwe yobukhulu enkulu ngokwentelekiso transistors. Iimodyuli SRAM zisetyenziswa ultra-fast cache imemori, esetyenziswa kwi abaqhubekekisi, drives hard kunye nezinye iimodyuli computer.

Uhlobo RAM olutshintshatshintshayo - kodwa onke imicwe yesiqhelo buxande, apho ibekwe phezu motherboard. Le imemori has ngexabiso eliphantsi kakhulu kunye nomthamo ophezulu. Kodwa yiyunithi kuneengxaki zawo;

• Ekubeni strip uqulathe capacitor, kuyimfuneko ukuba rhoqo "kwakhona" umwisele ukuze data azilahleki. Lo msebenzi lwenziwa yi-CPU. Kodwa xa ukungena imemori elibanjwe yonke imisebenzi kunye nayo.
• Isantya yale iplanga incinane kakhulu static.
• Lidlala indima ebalulekileyo kwaye ekhethiweyo kakuhle ixesha. RAM ininzi kakhulu kwaye aqhelelkileyo azisoloko nako ukubonisa imveliso eyimfuneko ngenxa kokulinganisa eliphezulu.

Types of RAM

Okwangoku, kukho iindidi 4 memory iimodyuli:

• DDR - kuphelelwa uhlobo RAM esetyenziswa kwi iikhompyutha ezindala kakhulu.
• DDR2 - ezifana iibhloko ze RAM lisekho kungafunyanwa iiPC abadala arhente zikarhulumente kunye namaziko emfundo. Isantya yale memory awuvumeli ukuba ukumelana nezicelo enzima mihla, kodwa kwanele lwenkqubo yokunikeza igama okanye ijonge i-Internet.
• DDR3 - lo mnqongo memory ixhaphakileyo. Ukusetyenziswa kwamandla yi-40% ngaphantsi kwe uhlobo owandulelayo, ezifana memory isantya yokusebenza iphezulu kakhulu.
• DDR4 - kwemvelo of RAM. Ezi iminqongo alukabinako ukwanelisa ngokupheleleyo zonke neemfuno umsebenzisi mihla. Xa unit uqwalaselo elilelona uyakwazi ukunika igalelo elenziwayo ilingana 34.1 GB / c.

memory laku

Ngoku siyazi into RAM. Kaloku, yintoni na ixesha? Oku kulibaziseka phakathi ukuthumela kunye nokuphunyezwa umyalelo memory ibhasi, nto leyo ulinganiswa kwimijikelo.

DRAM iqulathe iiseli zadityaniswa kwimiboniso emacala-mabini. Isakhiwo iyafana emkhusaneni, apho kukho iziza cell. Ukufikelela kwiindawo isilawuli kufuneka bazi idilesi zabo, equka amanani kumqolo lomhlathi (ezihambelanayo). Kwimiboniso ngamnye ubukhulu obufanayo iiseli adityaniswa ebizwa ngokuba yi-iibhanki.

Ngoko ke, lo umlawuli weposi onikeza umqolo yebhanki RAS idilesi uphawu lokuqala. Emva koko ke ukufuna elayinini kuyimfuneko - yinto RAS umjikelo ixesha ku CAS Makungalityaziswa. Emva koko, eli gosa uthumela inani kwikholam ne-CAS-uphawu. impendulo Kulindelwe kwisicelo eso kuthiwa CAS kokukhala. Ixesha ebizwa RAS Precharge umyalelo lixesha ophakathi komgca zokuvalwa lokuvula-, Active ukuya Precharge Delay - phakathi okuvula kunye imiyalelo yokuvala. Umyalelo Rate - yeyona lekhefu Ubuncinane phakathi amaqela amabini.

Xa uthenga entsha ibhari RAM kunokuba lula kakhulu ukugqiba ixesha. RAM ebhalwe scheme eqhelekileyo: DDR3 (frequency) CAS kokulinganisa - RAS to CAS UKULIBAZISA - RAS Precharge - Cycle Ixesha, eneneni Kubonakala ngathi DDR3 2133 9-12-12-28.

Kukuphi na okulunge ngakumbi - memory ngokukhawuleza okanye ngaphantsi kokulibazisa?

Into yokuqala ukunikela ingqalelo ixesha. RAM nge aqhelelkileyo kunokuba kade, ngenxa yokuba isibheno kumqhubekekisi unalo kwisantya asezantsi kakhulu, kwaye ngoko ke iadvanteji iya alukhange luqokeleleke ndaweninye. Kwangaxeshanye, ukulibaziseka zisoloko kwinqanaba umgangatho, Kakade ke, ukuba anithanga ubeke laku RAM ngesandla.

Ngoko ke, umzekelo, ka-DDR2 memory of 1600 6-7-6-18 ngokukhawuleza kakhulu DDR3 1866 9-9-9-24. Njengoko ubona, kwimeko yesibini sibe isizukulwana ogqibeleleyo RAM ngeqondo eliphezulu, kodwa ukulibaziseka kakhulu ezikhawulezileyo nje le nto. Ngokuthenga inkumbulo entsha, zama ukukhetha umfuziselo unalo ulibaziseko minimum kunokwenzeka. Le ndlela ukuqinisekisa wena eliphezulu ukusebenza computer xa iyonke.
