Cov txheej txheem ntawm cov tshuab computer hauv paus muaj xws li RAM. Nws yog siv los khaws cov ntaub ntawv thaum ua ntau yam haujlwm. Lub hom thiab cov yam ntxwv ntawm RAM yog nyob ntawm kev ruaj ntseg thiab kev ceev ntawm cov kev ua si thiab software. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv qhov no kom zoo, ua ntej tau kawm cov lus pom zoo.
Xaiv RAM rau lub computer
Tsis muaj dab tsi nyuab hauv xaiv ib lub RAM, koj tsuas yog xav paub txog nws cov tseem ceeb tshaj plaws thiab xav txog tsuas yog pov thawj kev xaiv, vim muaj nce fakes nyob rau hauv khw muag khoom. Cia peb saib ob peb qho kev xaiv uas koj yuav tsum tau them sai sai rau ua ntej koj yuav.
Saib kuj: Yuav ua li cas saib xyuas kev nco txog kev ua haujlwm
Cov qib siab ntawm RAM nco
Kev ua ntau yam dej num yuav tsum muaj ntau yam cim xeeb. PC rau chaw ua hauj lwm ua haujlwm yuav txaus 4 GB, uas yuav cia koj ua hauj lwm zoo rau 64-ntsis operating systems. Yog tias koj siv strips nrog tag nrho cov peev txheej tsawg dua 4 GB, ces koj yuav tsum nruab 32-ntsis OS hauv lub computer.
Cov kev ua si niaj hnub no yuav tsum tau tsawg kawg 8 GB ntawm lub cim xeeb, yog li thaum lub sij hawm no qhov kev pom zoo, tab sis sij hawm dhau los koj yuav tau yuav ib lub phaj thib ob yog tias koj yuav mus ua si tshiab. Yog tias koj npaj mus ua haujlwm nrog cov kev pab cuam los yog tsim kom muaj lub tshuab ua si haib, ces nws pom zoo kom siv li ntawm 16 mus rau 32 GB ntawm kev nco. Ntau dua 32 GB yog yuav tsum tau tsis tshua muaj neeg pom, tsuas yog thaum ua haujlwm heev.
Hom RAM
Lub computer cim hom DDR SDRAM tab tom ua, thiab nws muab faib ua ob peb yam. DDR thiab DDR2 cov outdated, niam motherboards tshiab tsis ua haujlwm nrog hom no, thiab hauv khw muag khoom nws yuav nyuaj rau nrhiav kev hom cim xeeb. DDR3 tseem siv tas li, nws ua haujlwm rau ntau yam qauv niam txiv tshiab. DDR4 yog qhov tseem ceeb tshaj plaws kev xaiv, peb xav kom yuav qhov cim xeeb ntawm hom no.
RAM loj
Nws yog ib qho tseem ceeb uas yuav tau them sai sai rau tag nrho qhov loj ntawm qhov kev tivthaiv kom tsis txhob yuam kev cov ntawv tsis zoo. Ib lub computer zoo tib yam yog qhov loj ntawm DIMM, qhov twg cov neeg muaj npe nyob rau ntawm ob sab ntawm lub voj voog. Thiab yog tias koj ua tau raws li lub prefix SO, ces lub phaj muaj lwm qhov ntau thiab siv feem ntau hauv cov laptops, tab sis qee zaus nws tuaj yeem pom muaj nyob hauv monoblocks lossis cov tshuab computer me me, vim qhov kev luj ntawm qhov system tsis tso cai txhim kho DIMMs.
Qhia kom meej zaus
Cov zaus ntawm RAM cuam tshuam nws cov ceev, tab sis koj yuav tsum them sai sai seb koj motherboard thiab processor txhawb qhov frequencies koj xav tau. Yog tias tsis yog, tus zaus yuav poob rau ntawm ib qho uas yuav ua tau tshaj lub Cheebtsam, thiab koj tsuas them tus nqi rau lub module.
Thaum lub sij hawm, qauv nrog frequencies ntawm 2133 MHz thiab 2400 MHz yog qhov feem ntau nyob rau hauv kev ua lag luam, tab sis lawv cov nqi tsis txawv ntau, yog li koj yuav tsum tsis txhob yuav thawj qhov kev xaiv. Yog tias koj pom cov hlab xo nrog cov zaus tshaj 2400 MHz, ces koj yuav tsum xav txog tias qhov no yog qhov ua tiav vim nws tsis siv neeg siv XMP technology (eXtreme Memory Profile). Tsis yog txhua tus niam ntawv them nyiaj yug nws, yog li koj yuav tsum tau ceev faj thaum xaiv thiab muag.
Lub sij hawm nruab nrab ntawm kev ua haujlwm
Lub sijhawm luv ntawm kev ua tiav ntawm kev ua haujlwm (sijhawm), lub sijhawm ua haujlwm yuav ceev dua. Cov yam ntxwv qhia tau tias plaub lub sij hawm tseem ceeb, uas lub ntsiab yog qhov nqi latency (CL). DDR3 yog tshwm sim los ntawm latency ntawm 9-11, thiab rau DDR 4 - 15-16. Tus nqi nce nrog rau zaus ntawm RAM.
Multichannel
RAM yuav ua hauj lwm hauv ib leeg-channel thiab multi-channel hom (ob, peb, los yog plaub-channel). Nyob rau hauv ob hom, cov ntaub ntawv teev tseg ib txhij nyob hauv txhua lub module, qhov no muab kev nce rau hauv kev ceev. DDR2 thiab DDR motherboards tsis txhawb ntau cov channel. Yuav tsum yog cov qauv zoo tib yam los pab rau hom no, kev khiav lag luam nrog cov sib txawv ntawm cov tuam ntxhab sib txawv tsis ruaj khov.
Los pab kom muaj hom kabmob dual-channel, koj yuav tsum muaj 2 lossis 4 slats ntawm RAM, peb-channel - 3 lossis 6, plaub-channel - 4 lossis 8 tuag. Raws li txoj kev sib tw dual txoj hauv kev lag luam, nws yog kev txhawb siab rau txhua tus niam txiv niaj hnub, thiab lwm ob yam yog cov qauv kim heev. Thaum txhim kho qhov tuag, xyuas cov connectors. Cov koog ntawm dual-channel hom yog kwv los ntawm kev ua ib daim kab xev los ntawm ib qho (feem ntau cov connectors muaj xim sib txawv, qhov no yuav pab ua kom haum).
Kub sib txawv
Lub xub ntiag ntawm no feem ntau tsis yog ib txwm tsim nyog. Tsuas yog DDR3 nco nrog lub siab heev tau kub heev. Niaj hnub nimno DDR4 txias, thiab radiators tsuas yog siv los ua ib qho kev dai siab. Cov neeg tsim tawm lawv tus kheej yog cov zoo li overpriced rau cov qauv nrog no ntxiv. Nov yog qhov peb xav kom txuag thaum xaiv ib lub rooj tsavxwm. Radiators kuj tuaj yeem cuam tshuam nrog installation thiab sai sai ua clogged nrog plua plav, qhov no yuav ua rau cov txheej txheem tu tsev ntawm lub tshuab.
Tshem nyiaj rau cov khoom siv nrog teeb pom kev zoo ntawm cov tshav kub hloov, yog tias nws yog qhov tseem ceeb rau koj kom muaj lub rooj sib ntsib zoo nkauj nrog teeb pom kev zoo rau txhua yam uas ua tau. Txawm li cas los xij, tus nqi rau cov qauv no yog siab heev, yog li koj yuav tsum tau them tshaj yog tias koj tseem txiav txim siab tau txais cov tshuaj qub.
System board connectors
Txhua hom kev nco tau teev muaj nws tus kheej hom ntawm lub qhov motherboard. Nco ntsoov sib piv cov yam ntxwv ntawm ob yam no thaum nriav khoom. Ib zaug dua peb nco qab tias cov motherboards rau DDR2 tsis tau ua ntxiv, kev daws teeb meem tsuas yog xaiv ib qho qauv ua lag luam hauv khw los yog xaiv los ntawm cov kev xaiv siv.
Sab saum toj manufacturers
Muaj tsis ntau manufacturers ntawm RAM rau lub lag luam tam sim no, yog li xaiv qhov zoo tshaj plaws yuav tsis yooj yim. Crucial manufactures optimal modules. Txhua tus neeg siv yuav tsum xaiv qhov kev xaiv zoo tagnrho, tus nqi yuav los kuj zoo siab.
Qhov nrov tshaj plaws thiab pom tau tias yog Corsair. Lawv tsim lub cim xeeb zoo, tab sis tus nqi rau nws yuav ua tau me ntsis overpriced, thiab feem ntau cov qauv muaj ib lub tshuab hluav taws xob built-in.
Ib qho tsim nyog tseem ceeb yog Goodram, AMD thiab Transcend. Lawv tsim cov qauv siv lag luam uas ua tau zoo, ua hauj lwm ntev thiab xwm yeem. Ib tug tsuas yog yuav tsum nco ntsoov tias AMD feem ntau tsis sib haum nrog lwm cov qauv thaum sim mus pab rau ntau hom channel. Peb tsis pom zoo kom yuav Samsung los ntawm cov foes nquag thiab Kingston - vim hais tias kev pluag tsim thiab tsawg tsawg.
Peb tau saib cov ntsiab lus tseem ceeb uas tseem ceeb txaus siab rau thaum xaiv RAM. Xyuas lawv tawm thiab koj yuav twv yuav raug hu ua txoj cai yuav khoom. Ib zaug dua kuv xav kom lawv mloog cov lus qhia nrog cov niam txiv nrog, kom nco ntsoov khaws qhov no.
