DDR3 vs DDR3L
Muaj qhov sib txawv me ntsis ntawm DDR3 thiab DDR3L hauv qhov tshwj xeeb raws li DDR3L yog hom tshwj xeeb ntawm DDR3. DDR3, uas sawv cev rau Ob Chav Cov Ntaub Ntawv Rate hom 3, yog hom RAM qhia hauv xyoo 2007. Tam sim no, nws yog hom siv ntau tshaj plaws ntawm RAM module rau PCs nrog rau cov khoom siv mobile xws li laptops. DDR3 xav tau qhov hluav taws xob ntawm 1.5V los ua haujlwm. Muaj ib hom tshwj xeeb ntawm DDR3 hu ua DDR3L, uas yog hais txog tus qauv qis voltage ntawm DDR3. Nws siv 1.35V es tsis txhob 1.5V li no lub zog siv tsawg dua. Cov qauv ntsuas hluav taws xob tsawg tsawg no tau siv dav hauv cov khoom siv mobile vim tias lawv siv lub zog tsawg dua uas ua rau lub roj teeb ntev dua.
DDR3 yog dab tsi?
DDR3, uas sawv cev rau Ob Chav Cov Ntaub Ntawv Tus Nqi Hom 3, yog hom Dynamic Random Access Memory (DRAM), uas tau los ua tus ua tiav ntawm DDR thiab DDR2. Nws tau tso tawm rau lub lag luam hauv xyoo 2007 thiab niaj hnub no feem ntau cov khoos phis tawj thiab laptops hauv khw siv DDR3 ua RAM. Qhov tshwj xeeb voltage rau DDR yog 1.5 V thiab, yog li ntawd, nws siv zog tsawg heev thaum piv rau nws cov thawj coj DDR thiab DDR2. DDR3 tus qauv tso cai chips mus txog 8 GB. DDR3 RAM muaj rau ntau zaus xws li 800, 1066, 1333, 1600, 1866, 2133 MHz. Lub DDR3 RAM module siv rau tus kheej lub computer muaj 240 tus pins thiab qhov ntev yog 133.35 hli. Lub DDR3 modules siv rau ntawm lub laptops hu ua SO-DIMM thiab nws qhov ntev me dua nrog qhov ntev ntawm 67.6 hli thiab tsawg tus pins, uas yog 204 tus pins.
DDR3L yog dab tsi?
DDR3L yog hom tshwj xeeb ntawm DDR3 RAM qhov twg tsab ntawv 'L' hais txog tus qauv qis qis. DDR3L tsuas yog siv 1.35V, uas yog 0.15V qis dua qhov siv hauv DDR3. Qhov zoo ntawm kev ua hauj lwm nyob rau hauv ib tug tsawg voltage yog hais tias lub hwj chim noj yog tsawg. Kev siv hluav taws xob tsawg dua txhais tau hais tias lub roj teeb zoo dua tuaj yeem ua tiav. Vim tias qhov no DDR3L feem ntau yog siv hauv cov khoom siv mobile xws li laptops thiab cov khoom siv embedded es tsis yog hauv PCs. Ib qho ntxiv kom zoo dua ntawm kev siv hluav taws xob tsawg yog qhov tsim hluav taws xob tsawg dua, uas yog qhov tseem ceeb dua rau cov khoom siv mobile compact. Lwm qhov tshwj xeeb xws li kev nco ceev, zaus thiab cov txheej txheem yog tib yam li hauv DDR3. DDR3L RAM feem ntau muaj xws li SO-DIMM modules uas yog 67.5 hli muaj 204 tus pins es tsis ntev DIMM modules. Yog vim li cas yog tias DDR3L yog tsom rau cov khoom siv txawb thiab lawv muaj SO-DIMM qhov.
D DR3 thiab DD R3L yog dab tsi?
• DDR3L yog hom tshwj xeeb ntawm DDR3 qhov L yog hais txog tus qauv qis qis.
• DDR3 xav tau qhov hluav taws xob ntawm 1.5V thaum DDR3L xav tau 1.35V xwb.
• DDR3L siv zog tsawg dua DDR3.
• DDR3L ua kom muaj cua sov tsawg dua thaum piv rau DDR3.
• DDR3L feem ntau yog siv hauv cov khoom siv txawb xws li lub laptops thiab cov khoom siv kos thaum DDR3 feem ntau yog siv hauv cov computers ntawm tus kheej. Txawm li cas los xij, tus re yog cov khoom siv txawb, uas siv DDR3 ib yam nkaus.
• Tus nqi lag luam ntawm DDR3L module yog siab dua li tus nqi lag luam ntawm DDR3 module.

Summary:
DDR3 vs DDR3L
Qhov sib txawv tseem ceeb ntawm DDR3 thiab DDR3L yog nyob rau hauv qhov tshwj xeeb voltage. Voltage specification rau DDR3 yog 1.5V, tab sis qhov voltage rau DDR3L yog tsawg, uas yog 1.35V. Tsab ntawv L hauv DDR3L yog hais txog tus qauv qis qis. Raws li DDR3L yog hom tshwj xeeb ntawm DDR3 tag nrho lwm yam tshwj xeeb tshwj tsis yog qhov hluav taws xob tseem zoo ib yam. Vim tias DDR3L xav tau qhov hluav taws xob tsawg dua, nws siv hluav taws xob tsawg thiab tsim hluav taws xob tsawg. Yog li ntawd, DDR3L tau dav siv rau cov khoom siv txawb uas xav tau lub roj teeb ntev dua.
