RAM yog thaj chaw ua haujlwm rau lub processor. Thaum lub koos pis tawj tseem khiav, nws khaws cov ntaub ntawv, thiab cov program uas ua haujlwm tam sim no. Random nkag nco tsuas yog cia ib ntus, txij li tom qab rov pib dua lossis kaw lub khoos phis tawm, tag nrho cov ntaub ntawv uas nyob hauv nws yuav raug tshem tawm. Thaum xaiv RAM, koj yuav tsum them sai sai rau cov cwj pwm hauv qab no.
Cov Lus Qhia
Kauj ruam 1
RAM hom. Thawj kauj ruam yog los txiav txim siab seb hom kev nco ntawm koj lub computer motherboard txhawb nqa yog dab tsi. Cov qauv ntawm ib hom RAM tsis tuaj yeem raug tso rau hauv cov qhov uas tau npaj rau ntau hom. Yog li no, cov qib tau tsim nyob hauv ntau hom qauv:
DDR - niaj hnub no hom RAM no tsis muaj hnub nyoog, nws tau siv tsis yog hauv cov khoos phis tawj niaj hnub no.
DDR2 yog qhov kev nco tshaj plaws rau lub sijhawm tam sim no. DDR2 muaj peev xwm hloov 4 kis ntawm cov ntaub ntawv ib lub voj voog los ntawm cov hlwb ntawm RAM nti mus rau I / O tsis. Qhov qauv no muaj 240 pins, thiab nws qhov txheem txheem voltage yog 1.8 V.
DDR3 yog lub cim tshiab tshiab. Nws tso cai rau koj pauv 8 daim rau ib lub moos. Nws cov qauv tau tsim nyob rau hauv daim ntawv ntawm lub rooj tsavxwm nrog 240 pins, tab sis kev siv fais fab yog 40% tsawg dua piv rau DDR2, uas yog qhov tseem ceeb heev rau lub xov tooj ntawm tes thiab lub khoos phis tawm.
Kauj ruam 2
Bandwidth.
Koj lub khoos phis tawm yuav khiav tawm sai dua yog tias RAM lub npav tsheb npav sib txig sib luag ntawm cov npav tso tsheb npav. Tsis tas li, thaum txhim kho ob lub cim xeeb, lub khoos phis tawm tuaj yeem siv dual-channel hom (nws yog qhov tsim nyog tias ob lub RAM modules ua haujlwm rau tib lub sijhawm). Cov motherboard niaj hnub muaj peev xwm siv peb-channel hom, qhov no nws yog qhov tsim nyog los txuas peb DDR3 RAM modules.
Kauj ruam 3
Tus nqi ntawm RAM.
Cov qauv nrov tshaj plaws yog 512MB, 1GB, 2GB. Koj xaiv yuav nyob ntawm qhov koj xav tau computer siv rau. Piv txwv li, yog tias koj tsuas yog siv koj lub khoos phis tawm rau cov chaw ua haujlwm, tom qab ntawd 1GB txaus, tab sis rau cov gamers koj xav tau tsawg kawg 2GB.
