Laptop nco: hom thiab txoj kev nce

RAM nco (RAM) yog ib feem ntawm txhua txhua lub computer. Nws yog siv los khaws cov neeg siv cov ntaub ntawv. Thiab tsuas yog tus ntaub ntawv uas peb yuav ua hauj lwm nyob rau ntawm no heev lub sij hawm ntawd. Nws yog ib nqi mus pib dua lub computer, thiab "RAM" ntxuav. Cia li hauv qab no peb yuav saib qhov txawv ntawm RAM thiab ib tug laptop PC.

Lub ntsiab yam ntawm

Random-mus saib nco (RAM) yog muab faib ua ob peb hom: DDR, DDR II thiab DDR III. Muaj kuj yog ib tug heev ancient: ROM, SRAM, SDRAM thiab DRAM. Tab sis nyob rau hauv qhov ntsiab lus teb, lawv tsis nyiam peb, vim hais tias qhov no yog lub xyoo pua xeem. Cov "RAM" nyob rau hauv ob peb qhov chaw muaj peev xwm tam sim no yuav pom. Tag nrho cov ntawm lawv siv xwb SRAM. Vim qhov no hom ntawm OP muaj ib tug kev kub ceev, nws yog feem ntau yog siv rau cov processor cache. Qhuav ntawm xws "RAM" kim thiab kim. Yog li ntawd, ua nrog cov coob loj ntawm lub peb-theem cache thiab raug nqi nyiaj loj.

DDR thiab DDR II heev maj mam fading. Lawv ceev thiab cov nyiaj ntawm lub cim xeeb tsis mus rau kev sib piv nrog DDR III. Niaj hnub no nws yog DDR III - pom RAM Laptop thiab PC.

Yuav ua li cas yog DDR?

Ob chav ntaub ntawv Rate yog lub "advanced" zoo ntawm SDRAM. DDR yog txhais los ntawm lus Askiv raws li "ob cov ntaub ntawv tus nqi". Qhov no txhais tau tias cov kev ceev ntawm cov ntaub ntawv pauv "RAM" nrog rau cov processor ob peb lub sij hawm siab tshaj hais tias ntawm SDRAM. Serial tooj, los tom qab cov tsiaj ntawv qhia lub cim ntawm OP. Qhov txawv nruab nrab ntawm lawv yog lub cim xeeb kawm ntawv.

Piv txwv li, tus thawj tiam ntawm DDR RAM nco tau khiav lag luam rau cov chaw tos tsheb loj zaus nyob rau hauv 100-400 MHz. Ib tug DDR III dawb do "ya" nyob rau lub log nyob rau hauv lub 800-1600 MHz zaus. Raws li, DDR III yog tsim los qhia kom tus loj tshaj xov tooj ntawm haujlwm ib ob thaum siv cov yam tsawg kawg tus nqi ntawm lub hwj chim. Nws yog qhov no parameter yog yam nyob rau hauv tej rooj plaub. Piv txwv li, lub cim xeeb ntawm laptop yuav tsum tau siv me me ntawm lub hwj chim los ua kom roj teeb lub neej. PC qhov chaw tsis yog tshwj xeeb tseem ceeb heev. Yog hais tias tsuas nyob rau hauv cov nqe lus ntawm nqi hluav taws xob nyob rau hauv feem ntau.

HDD

Sib nrug los ntawm ua hauj lwm, tej zaum cov kab lus "nco Laptop" txhais hais tias lub hauv ntaub ntawv cia ntaus ntawv. Qhov no thiaj li hu ua hard disk. Nws ua hauj lwm kuj yog tsis muaj dab tsi sib txawv ntawm cov kev tivthaiv uas yog tam sim no nyob rau hauv desktop computers. Ib tug txawv loj. Thiab tsis tooj mus rau yuav luag tag nrho cov lwm yam Cheebtsam ntawm lub laptop, lub zog tsav hloov yog muab rau tag nrho cov ntau dua los yog tsawg niaj hnub pab kiag li lawm. Cov txheej txheem tsis tau siv zog npaum. Raws li cov chaw tsim tshuaj paus qub tas tag nrho cov drives ua hauj lwm zoo nrog txawv laptops.

Xaiv cov pom RAM rau PC

Yuav kom raug xaiv pom "RAM" rau koj lub computer los yog laptop, koj yuav tsum paub ib co ntawm cov nuances. Thiab nyob rau hauv cov ntaub ntawv ntawm ib tug desktop computer txhua yam yog yooj yim npaum li. Nyob rau hauv thiaj li yuav ntxiv nco mus rau lub phau ntawv sau, koj yuav tsum tau kom nyob rau hauv lub siab ib tug ob peb tseem ceeb cov ntsiab lus, tab sis hais txog lawv yav tom ntej.

Yog li ntawd, rau cov kev xaiv ntawm OP PC koj yuav tsum paub cov nyiaj pab ntau tshaj bus ceev kev txhawb los ntawm koj motherboard. Nws ua rau tsis muaj kev nkag siab rau yuav "RAM" nrog ib zaus ntawm 1300 MHz, Yog hais tias koj "motherboard" txhawb nqa 1600 MHz. Ces koj yuav tau xyuas seb qhov ntim ntawm "RAM". Yog hais tias koj tsis npaj rau tov txhua yam ntawm "tseem ceeb tshaj plaws ua hauj lwm", uas yuav tsum tau txaus, "lub bar" qhov luaj li cas ntawm 16 GB.

Tsis tag li ntawd no, koj yuav tsum ua raws li thiab rau tus nqi ntawm cov hluav taws xob noj. Yog hais tias koj yuav poob "voracious" nco, lub peev xwm ntawm koj lub hwj huam mov tej zaum yuav tsis txaus los mus xyuas kom meej tias tag nrho cov Cheebtsam ntawm koj lub computer. Nyob rau hauv tus neeg mob ntawm portable devaysa txhua yam yog ntau yooj yim. Piv txwv li, lub cim xeeb ntawm laptop feem ntau yog tas rau txog lub hwj chim noj. Thiab nws yog heev muaj txiaj ntsim rau tus tswv tsev.

Xaiv cov "RAM" Laptop

Ua ntej hloov qhov yuav tsum tau mus nrhiav tau tawm yog dab tsi "sawb" koj tau ntsia. Qhov tseeb hais tias qhov thiaj li nrov DDR muaj ib qho kev nthuav subspecies - DDRL. Qhov no lub cim xeeb nrog cov uas tsis muaj zog noj. Yuav kom xaiv tau qhov "tseeb" nco rau lub ASUS laptop, piv txwv li, muaj mus nrhiav nws DDRL. Qhov no lub tuam txhab feem ntau tsim xws li ib tug ntaus ntawv rau hauv lawv cov laptops. Thaum koj ntxig ib laptop ob tug sib txawv los ntawm txhua lwm yam nti, muaj ib tug teeb meem ntawm lub Cheebtsam thiab lub computer tsuas yuav tsis ua hauj lwm. Yuav kom txiav txim seb lub hom ntsia "RAM" Peb pom zoo kom siv Aida 64. Nws lub meej piav qhia.

Nyob rau hauv thiaj li yuav xaiv lub cim xeeb rau ib tug laptop, koj yuav tsum paub ntau ntxiv thiab cov zaus ntawm nws cov log tsheb. Qhov no yog tsis yog ib tug PC, thiab ntawm no muab OP zaus yog tsis tso tawm. Yog hais tias koj muaj "RAM" yuav tsum ua hauj lwm rau 1066 MHz, thiab qhov yuav tsum tau mus yuav li.

Ua RAM

Ib txhia laptops muaj ib qhov rau ib qho ntxiv OP. Qhov no, ntawm chav kawm, tsis txhais hais tias nws muaj peev xwm ntxiv mus rau infinity. Feem ntau, cov chaw tsim tshuaj paus nruj me ntsis txwv tus nqi ntawm lub cim xeeb tau. Feem ntau cov ntaub ntawv no yog teev nyob rau hauv cov kev cov ntaub ntawv ntaus ntawv.

Yuav ua li cas kom lub cim xeeb rau ib tug laptop? Qhov yooj yim xaiv - mus yuav ib tug "bar" ntawm tib pre-ntsia. Qhov no yuav pab tau kom nrog lub ntim thiab zaus ntawm lub tsheb npav. Nyob rau hauv tas li ntawd, tsis muaj teeb meem ntawm cov khoom. "Slats" RAM los ntawm ntau cov neeg muag khoom yog tsis yog tshwj xeeb xav "ua phooj ywg" nrog txhua lwm yam.

Yog hais tias koj xav los hloov tag nrho cov RAM ib zaug, ces ua ntej koj yuav tau kawm ib co yam ntxwv ntawm koj lub OP. Piv txwv li, lub tsheb ceev, lub siab tshaj plaws volume, thiab tus nqi ntawm cov hluav taws xob noj. Thiab tsis tau, nws yog pom zoo kom yuav ob "daim hlab" ntawm lub tib lub chaw tsim tshuaj paus. Tsawg yuav ua rau muaj kev tsis sib haum. Xaiv RAM rau ib tug laptop yog ib qho tseem ceeb rau koj nco ntsoov txog lub specifications. Nco ntsoov tias lub tsheb npav zaus thiab voltage matched.

xaus

RAM tso cai koj lub computer los qhia txhua yam nws muaj peev xwm ua. Cov xaiv txoj kev nyob rau hauv cov ntaub ntawv no yuav ua rau kom qhov kev kawm ob peb lub sij hawm. Ntawm cov hoob kawm, yog tias koj ua yuam kev, koj muaj peev xwm "dai" lub tag nrho qhov system. Tab sis nrog rau kev pab los ntawm no tsab xov xwm thiab ib co ntawm cov kev pab cuam koj yuav xaiv tus "muaj tseeb" nco rau phau ntawv sau thiab PC.
