Cov txheej hauv lub koos pij tawj tseem ceeb muaj xws li RAM. Nws yog siv los khaws cov ntaub ntawv thaum lub sijhawm ntau cov haujlwm. Qhov kev ruaj khov thiab ceev ntawm kev ua si thiab software nyob ntawm hom thiab cov yam ntxwv tseem ceeb ntawm RAM. Yog li, nws yog ib qho tsim nyog yuav tau xaiv cov khoom siv no ua tib zoo, muaj yav tas los kawm cov lus pom zoo.
Xaiv RAM rau lub computer
Tsis muaj dab tsi nyuaj hauv kev xaiv RAM, koj tsuas yog xav paub nws cov yam ntxwv tseem ceeb tshaj plaws thiab xav txog cov kev xaiv pov thawj xwb, txij li cov khoom cuav tau nce ntau hauv cov khw. Cia peb saib ob peb txoj hauv kev uas koj yuav tsum them sai sai ua ntej koj yuav.
Saib ntxiv: Saib xyuas RAM li cas rau kev ua haujlwm
Cov qib siab ntawm RAM lub cim xeeb
Ua ntau cov haujlwm xav tau qhov sib txawv ntawm cov cim xeeb. Lub PC rau kev ua haujlwm yog txaus 4 GB, uas tseem yuav cia koj kom xis nyob ua haujlwm ntawm 64-ntsis OS. Yog tias koj siv cov cim nkhaus uas muaj tag nrho cov ntim tsawg dua 4 GB, tom qab ntawd tsuas yog 32-ntsis OSs yuav tsum muab nruab rau hauv lub computer.
Cov kev ua si niaj hnub yuav tsum muaj tsawg kawg yog 8 GB ntawm kev nco, yog li tam sim no tus nqi no yog qhov zoo dua, tab sis dhau sijhawm koj yuav tau yuav ib tus neeg tuag thib ob yog tias koj yuav mus ua si tshiab. Yog tias koj npaj ua haujlwm nrog cov kev pabcuam nyuaj lossis tsim kom muaj lub tshuab muaj zog, ces nws raug nquahu kom siv los ntawm 16 txog 32 GB ntawm lub cim xeeb. Ntau dua 32 GB yog qhov tsis tshua muaj, tsuas yog thaum ua txoj haujlwm nyuaj heev.
RAM Hom
Lub cim xeeb hauv computer xws li DDR SDRAM tab tom tsim tawm, thiab nws tau muab faib ua ntau yam tshwj xeeb. DDR thiab DDR2 yog qhov kev xaiv uas tsis tsim nyog, niam tshiab tsis ua haujlwm nrog hom no, thiab hauv khw muag khoom nws nyuaj rau nrhiav hom kev nco no. DDR3 tseem nquag siv; nws ua haujlwm rau ntau tus qauv niam tshiab. DDR4 yog qhov kev xaiv zoo tshaj plaws; peb pom zoo xaiv lub RAM no.
Qhov loj me RAM
Nws yog ib qho tseem ceeb heev uas yuav tsum them sai sai rau txhua qhov ntev ntawm qhov feem, thiaj li tsis yog yuam kev tau txais qhov tsis yog. Lub koos pij tawj raug pom muaj los ntawm DIMM qhov loj me, qhov twg cov neeg nyob sib txuas ntawm ob tog ntawm lub cim. Thiab yog tias koj ntsib SO ua ntej, lub phaj muaj ntau qhov sib txawv thiab feem ntau siv hauv laptops, tab sis qee zaum nws tuaj yeem pom hauv monoblocks lossis cov khoos phis tawj me me, vim tias qhov loj me ntawm qhov system tsis tso cai koj teeb DIMM.
Qhia pes tsawg zaus
Qhov ntau zaus ntawm RAM cuam tshuam txog nws qhov ceev, tab sis koj yuav tsum them sai sai seb koj lub motherboard thiab cov processor txhawb nqa cov zaus uas koj xav tau. Yog tias tsis yog, tom qab ntawd qhov zaus yuav poob mus rau ib qho uas yuav siv tau nrog cov khoom sib txuas, thiab koj tsuas yog them tshaj rau tus qauv.
Lub sijhawm no, cov qauv uas feem ntau ntawm kev ua lag luam yog cov zaus ntawm 2133 MHz thiab 2400 MHz, tab sis lawv cov nqi tau zoo ib yam nkaus, yog li koj yuav tsum tsis txhob yuav thawj qhov kev xaiv. Yog tias koj pom cov hlua khi nrog qhov zaus tshaj 2400 MHz, tom qab ntawd koj yuav tsum txiav txim siab tias qhov zaus no tau ua tiav vim nws tsis siv neeg nce siv XMP technology (eXtreme Memory Profile). Tsis yog txhua tus motherboard txhawb nws, yog li koj yuav tsum ua tib zoo xaiv thaum xaiv thiab yuav.
Lub sijhawm ntawm kev ua haujlwm
Lub sijhawm luv luv ntawm cov sijhawm ntawm kev ua haujlwm (Sij Hawm), lub cim xeeb nrawm yuav ua haujlwm. Cov yam ntxwv qhia txog plaub sij hawm tseem ceeb, uas lub ntsiab tseem ceeb yog latency (CL). DDR3 yog tus cwj pwm los ntawm latency 9-11, thiab rau DDR 4 - 15-16. Tus nqi nce nrog qhov zaus ntawm RAM.
Multichannel
RAM muaj peev xwm ua haujlwm hauv ib-channel thiab ntau hom channel (ob, peb lossis plaub-channel). Hauv ob hom, cov ntaub ntawv yuav muab sau ua ke hauv txhua qhov, qhov no muab kev ua tau zoo ntxiv. Cov niam tsev ntawm DDR2 thiab DDR tsis txhawb nqa ntau cov channel. Yuav tib qho tib qho qauv kom thiaj li siv tau hom no, kev ua haujlwm ib txwm nrog kev tuag los ntawm cov tuam ntxhab sib txawv tsis lav.
Txhawm rau kom ob-channel hom, koj xav tau 2 lossis 4 RAM qhov, 3-channel - 3 lossis 6, plaub-channel - 4 lossis 8 tsuav. Raws li rau ob-channel hom kev ua haujlwm, nws tau txais kev txhawb nqa los ntawm yuav luag txhua lub motherboard niaj hnub, thiab lwm qhov ob yog tus qauv kim xwb. Thaum txhim kho cov tuag, saib ntawm cov txuas. Qhov ob-channel hom tau hloov los ntawm kev teeb tsa cov ib daim hlab los ntawm ib qho (feem ntau cov txuas sib txuas tau muaj xim sib txawv, qhov no yuav pab txuas tau kom raug).
Cov pa taws ua kom sov
Lub xub ntiag ntawm cov khoom tiv thaiv no tsis yog tsim nyog tas li. Tsuas yog DDR3 lub cim xeeb nrog lub siab siv yog kub heev. Niaj hnub nimno DDR4s yog txias, thiab hluav taws xob tsuas yog siv los ua dai kom zoo nkauj xwb. Cov neeg tsim khoom lawv tus kheej zoo overestimate tus nqi ntawm cov qauv nrog xws li ib qho ntxiv. Qhov no yog qhov peb xav tau khaws cia thaum xaiv pawg thawj coj. Lub tshuab hluav taws xob tseem tuaj yeem cuam tshuam nrog cov kev teeb tsa thiab sai sai nrog cov hmoov av, qhov no yuav ua rau cov txheej txheem ntawm kev ntxuav chav ua haujlwm.
Ua tib zoo saib cov pob hluav taws xob sab nraub qaum ntawm cov cuab yeej ua kom sov, yog tias nws yog qhov tseem ceeb rau koj kom muaj lub rooj sib txoos zoo nkauj nrog lub teeb pom kev zoo ntawm txhua yam uas tuaj yeem. Txawm li cas los xij, tus nqi ntawm cov qauv zoo li no yog ntau heev, yog li koj yuav tsum them nyiaj tshaj yog tias koj tseem txiav txim siab kom tau txais kev daws teeb meem qub.
Txuas rau motherboard
Txhua cov npe cim xeeb muaj nws tus kheej hom txuas ntawm lub kaw lus tswj hwm. Nco ntsoov sib piv ob yam ntxwv no thaum yuav khoom siv. Peb nco ntsoov koj ib zaug ntxiv tias motherboard rau DDR2 yog tsis tau tsim dua tshiab, kev daws teeb meem tsuas yog xaiv cov qauv qub nyob rau hauv lub khw lossis xaiv cov kev xaiv siv.
Cov tuam ntxhab sab saum toj
Tsis muaj ntau lub tuam txhab RAM ntawm lub khw tam sim no, yog li nws tsis yog qhov ntau los xaiv qhov uas zoo tshaj plaws. Kev lag luam tseem ceeb tsim cov qib siab zoo tshaj. Txhua tus neeg siv yuav muaj peev xwm xaiv qhov kev xaiv zoo tshaj plaws, tus nqi kuj yuav ua rau koj xav tsis thoob.
Cov hom nrov tshaj plaws thiab paub tau yog Corsair. Lawv tsim cov cim xeeb zoo, tab sis tus nqi yuav nce siab me ntsis, thiab cov qauv feem ntau muaj cov ntsuas hluav taws xob hauv.
Tseem muaj nqis sau cia yog Goodram, AMD thiab Transcend. Lawv tsim cov qauv pheej yig uas ua tau zoo, ua haujlwm ntev thiab ruaj khov. Nws yog tsim nyog sau cia tias AMD feem ntau tsis sib haum nrog lwm tus qauv thaum sim qhib rau ntau hom channel. Peb tsis pom zoo kom Samsung yuav vim yog cov ntawv sau cuav thiab Kingston - vim tias kev sib dhos tsis zoo thiab qhov tsis zoo.
Peb tau soj ntsuam cov yam ntxwv tseem ceeb uas koj yuav tsum them sai sai rau thaum xaiv RAM. Kuaj lawv thiab koj yuav twv yuav raug hu ua txoj kev yuav khoom. Ib zaug ntxiv Kuv xav tau them sai sai rau qhov tsis tau ntawm cov qauv nrog cov motherboard, nco ntsoov txiav txim siab qhov no.
