Random nkag nco yog thaj chaw ua haujlwm rau kev khaws cia ib ntus ntawm cov ntaub ntawv tam sim no. Cov ntaub ntawv los ntawm lub cim xeeb ntawm random nkag tau muab tshem tawm thaum lub hwj chim muab tua, i. E. qhov nco no yog qhov hloov. Kev ceev ntawm lub khoos phis tawm yog txiav txim siab dav dav los ntawm cov yam ntxwv ntawm RAM, lossis RAM (Random Nkag Nkiag).
Cov Lus Qhia

Txhawm rau kom muaj qhov loj me me nco rau ntawm koj qhov system system, koj yuav tsum nrhiav kom pom yam twg ntawm cov cim xeeb koj lub motherboard txhawb nqa. Mus rau lub chaw tsim khoom lag luam lub vev xaib thiab paub cov teeb meem no. Muaj peb yam ntawm RAM siv nyob rau hnub no:
- DDR - hauv ib qho kev ua haujlwm, 2 tus lej ntawm cov ntaub ntawv kis tau los ntawm txhua tus I / O tsis. Qhov module (luam tawm cov ntawv Circuit rau ntawm qhov uas tus lej cim xeeb daim tawv muag) muaj 184 pins. Qhov muab cov mov hluav taws xob yog 2.5 V. Lub cim xeeb no twb yuav luag qub thiab tsis txaus siab los ntawm cov niam tsev tshiab;
- DDR2 - cov ntaub ntawv hloov chaw yog 2 zaug siab tshaj li ntawm DDR, i.e. 4 txoj hauv kev ib puag ncig, kev khiav hauj lwm voltage 1, 8 V thiab 240 tiv tauj ntawm module;
- DDR3 - hloov tsheb 8 me me ib lub voj voog ua haujlwm. Yuav tsum tau tsuas yog 1.5V muab voltage. Ib yam li DDR2 module, muaj 240 pins.
Qhov qis dua ntawm cov khoom siv voltage, qhov ntsuas kub zoo dua ntawm cov cim xeeb lub cim xeeb thiab tag nrho cov kab ke ua ib qho. Qhov no tseem ceeb heev rau cov laptops.

Ua tib zoo saib thaum yuav thiab sim txhim kho RAM strips ntawm lub motherboard: daim ntawv foos ntawm txhua yam peb ntawm kev nco txawv nyob hauv qhov kev tso kawm ntawm tus yuam sij (qhov) ntawm cov pins. Lub laj kab ntawm ib hom tsis tuaj yeem raug tso rau hauv ib txoj kab txuas rau lwm hom yam tsis muaj qhov tawg rau cov qauv lossis pob qhov. Qee cov motherboard muaj qhov txuas rau DDR2 thiab DDR3, tab sis tsuas yog kev nco ntawm tib lub hom tuaj yeem ua haujlwm tib lub sijhawm: ob qho los yog DDR2 lossis DDR3.

Tus cwj pwm tseem ceeb ntawm RAM yog bandwidth. Nws yog sib npaug nrog cov khoom ntawm lub moos ntawm lub moos thiab tus nqi ntawm cov ntaub ntawv kis hauv ib lub moos kev voj voog. Nco ntsoov tias lub cim xeeb moos ceev yuav tsum sib phim qhov system tsheb npav moos ceev - lub cim xeeb siab nrawm tsuas yog tsis txaus siab los ntawm motherboard. Qhov high-speed module yuav ua haujlwm ntawm qhov system tsheb npav lub cav, thiab nws lub peev xwm zoo kawg yuav siv sijhawm.

Cov sijhawm nco tseem ceeb yog qhov tseem ceeb - tus lej ntawm kev voj voog nyob nruab nrab ntawm cov sij hawm tuaj txog ntawm kev hais kom ua thiab nws ua tiav. Tsawg dua sijhawm ua tiav, qhov kev ua haujlwm siab dua. Tsis yog txhua tus muag muag xav tias nws tsim nyog los qhia txog qhov ntsuas no, yog li, ua ntej yuav ib lub cim xeeb, mus rau hauv lub khw tsim lub vev xaib thiab ua tib zoo kawm tag nrho cov yam ntxwv

Kev ua haujlwm sib luag ntawm ob qhov cim xeeb zoo ib yam yog hu ua dual channel hom. Hauv qhov no, kev hloov ntaub ntawv ob yog ob npaug. Txhawm rau kom cov modules tau lav zoo tib yam, nws zoo dua yuav cov khoom siv - cov khoom siv uas tsim los ua haujlwm hauv ob-channel hom. Cov qauv hauv cov khoom siv no tau sim thaum ua haujlwm ua ke.

Disconnect qhov system chav tsev ntawm lub hwj huam muab. Tshem tawm cov sab vaj huam sib luag thiab ntxig rau lub cim xeeb cim xeeb mus rau hauv cov sib txuam qhov cuam tshuam kom txog thaum koj hnov hnov. Cov yeeb yaj kiab yas thaiv cov kab txaij nyob rau hauv lub qhov qhib yuav tsum kaw. Tom qab tig lub computer, thaum pov npav hlau, qhov loj me ntawm RAM qhia nyob rau kab thib ob ntawm lub vijtsam. Yog tias lub cim xeeb tau txais kev txhawb nqa los ntawm cov niam tsev thiab koj tau nruab rau cov qauv kho kom raug, lub kaw lus yuav ua kom pom qhov raug.
