Lub cim xeeb zoo rau lub computer yog dab tsi? Feem ntau cov khoos phis tawj cov lus qhia tshwj xeeb zoo li sau lub cim xeeb lossis RAM tam sim tom qab CPU. Hauv phau ntawv qhia no, peb tshawb txog ob yam tseem ceeb ntawm RAM saib hauv computer specifications: tus nqi thiab hom.
Nco Ntsoov txaus?
Txoj cai ntawm tus ntiv tes xoo rau txhua lub khoos phis tawj los txiav txim siab seb nws puas muaj lub cim xeeb txaus yog saib cov kev xav tau ntawm software koj npaj siab yuav khiav. Tshawb xyuas lub vev xaib rau txhua daim ntawv thov thiab OS uas koj xav khiav. Nrhiav kom paub qhov yam tsawg kawgthiab pom zooqhov xav tau.
Ntau RAM ntau dua qhov tsawg kawg nkaus thiab tsawg kawg yog ntau npaum li qhov siab tshaj plaws tau teev tseg qhov xav tau yog qhov zoo tagnrho. Daim ntawv qhia hauv qab no qhia txog lub tswv yim dav dav ntawm yuav ua li cas lub computer yuav khiav nrog ntau lub cim xeeb:
- Yam tsawg kawg: 4 GB
- zoo: 8 GB
- Smooth Sailing: 16 GB lossis ntau dua
Cov kab uas tau muab yog qhov kev qhia dav dav raws li kev ua haujlwm suav nrog. Nws yog qhov zoo tshaj plaws los xyuas cov kev cai ntawm cov software npaj los txiav txim siab zaum kawg. Qee lub tshuab ua haujlwm siv lub cim xeeb ntau dua li lwm tus.
Yog tias koj npaj siab yuav siv ntau dua 4 GB ntawm lub cim xeeb ntawm lub khoos phis tawj Windows, koj yuav tsum muaj 64-ntsis operating system kom dhau los ntawm 4 GB teeb meem. Nws tsis tshua muaj teeb meem tam sim no vim tias feem ntau PCs xa nrog 64-ntsis versions. Tseem, Microsoft muag Windows 10 nrog 32-ntsis versions.
Puas Hom Tseem Ceeb?
Hom kev nco tseem ceeb rau kev ua haujlwm ntawm lub computer. DDR4 tau raug tso tawm thiab muaj rau ntau lub khoos phis tawj desktop ntau dua li qhov qub. Muaj ntau lub khoos phis tawj uas siv DDR3. Nrhiav seb hom kev nco twg yog siv rau hauv lub computer, vim nws tsis hloov pauv, thiab nws tseem ceeb heev yog tias koj npaj yuav hloov kho lub cim xeeb yav tom ntej.
Feem ntau, lub cim xeeb tau teev nrog cov thev naus laus zis siv thiab nws lub moos ceev (DDR4 2133 MHz) lossis nws qhov phiaj xwm bandwidth (PC4-17000). Hauv qab no yog ib daim ntawv qhia qhia txog hom thiab ceev nyob rau hauv qhov kev txiav txim ntawm ceev tshaj mus rau qeeb tshaj plaws:
- DDR4 3200 MHz lossis PC4-25600
- DDR4 2666 MHz lossis PC4-21300
- DDR4 2133 MHz lossis PC4-17000
- DDR3 1600 MHz lossis PC3-12800
- DDR3 1333 MHz lossis PC3-10600 / PC3-10666
- DDR3 1066 MHz lossis PC3-8500
- DDR3 800 MHz lossis PC3-6400
Cov kev nrawm no yog txheeb ze rau qhov theoretical bandwidths ntawm txhua hom kev nco ntawm nws lub moos ceev thaum piv rau lwm qhov. Lub tshuab computer tsuas tuaj yeem siv ib hom (DDR3 lossis DDR4) ntawm lub cim xeeb. Qhov no tsuas yog siv los ua kev sib piv thaum CPU zoo ib yam ntawm ob lub khoos phis tawj.
Cov no kuj yog JDEC cov qauv kev nco. Lwm lub cim xeeb ceev muaj nyob saum cov qauv ntsuas no. Txawm li cas los xij, cov kev ceev no feem ntau tshwj tseg rau cov khoos phis tawj uas yuav raug overclocked.
Dual-Channel thiab Triple-Channel
Ib qho ntxiv ntawm kev ceeb toom rau lub computer nco yog dual-channel thiab triple-channel configuration. Feem ntau cov khoos phis tawj desktop tuaj yeem muab kev txhim kho kev nco bandwidth thaum lub cim xeeb tau teeb tsa ua khub lossis triple, hu ua dual-channel thaum nws nyob hauv khub thiab triple-channel thaum nyob rau hauv peb.
Yog tias lub cim xeeb sib xyaw, xws li 4 GB thiab 2 GB module lossis qhov sib txawv ntawm qhov sib txawv, hom dual-channel yuav tsis ua haujlwm, thiab lub cim xeeb bandwidth yuav qeeb me ntsis.
Nco ntsoov nthuav dav
Lwm qhov kev txiav txim siab yog qhov nco ntawm lub computer tuaj yeem txhawb nqa. Feem ntau cov khoos phis tawj desktop zoo li muaj tag nrho ntawm plaub mus rau rau lub cim xeeb ntawm cov laug cam nrog cov qauv teeb tsa ua khub.
Cov khoos phis tawj me me feem ntau tsuas muaj ob lossis peb qhov RAM. Txoj kev siv cov slots no tuaj yeem ua lub luag haujlwm tseem ceeb hauv qhov koj tuaj yeem txhim kho lub cim xeeb yav tom ntej.
Piv txwv li, lub computer yuav tuaj nrog 8 GB ntawm lub cim xeeb. Nrog plaub lub cim xeeb slots, lub cim xeeb no tuaj yeem nruab nrog ob lub cim xeeb 4 GB lossis plaub 2 GB modules.
Yog tias koj tab tom saib yav tom ntej nco kev hloov kho tshiab, nws yog qhov zoo dua los yuav lub khoos phis tawj siv ob 4 GB modules vim tias muaj qhov muaj rau kev hloov kho yam tsis tas yuav tshem tawm cov modules thiab RAM kom nce tag nrho cov nyiaj.
