Qhov sib txawv ntawm SO-DIMM, U-DIMM, R-DIMM, thiab LR-DIMM nco modules

SODIMM (Small Outline Dual In-line Memory Module) Cov qauv me me dual hauv-kab nco module

Nws yog hom khoos phis tawj nco module, feem ntau yog siv hauv phau computers thiab lwm yam kev siv uas muaj qhov xav tau ntau dua rau qhov loj. Yog ib hom computer memory module. Piv rau DIMMs, SO-DIMMs muaj ib daim ntawv me me (kwv yees ib nrab ntawm qhov loj ntawm DIMMs ib txwm). Yog li ntawd, SO-DIMM feem ntau yog siv hauv cov khoos phis tawj laptop thiab lwm yam kev siv uas muaj qhov xav tau siab rau qhov loj. Yog li-dimms muaj nyob nrog 72 tus pin (txhawb 32-ntsis cov ntaub ntawv hloov chaw) lossis 144 tus pins lossis 200 tus pins (txhawb 64-ntsis cov ntaub ntawv hloov chaw).

Txhawm rau kom ua tau raws li qhov xav tau ntawm lub cim xeeb loj ntawm cov khoos phis tawj phau ntawv, SO-DIMM (Small Outline DIMM Module) kuj tau tsim, uas yog me dua li tus qauv DIMM loj, thiab tus naj npawb ntawm cov pins tsis zoo ib yam. Yog li-dimms kuj txawv raws li SDRAM thiab DDR lub cim xeeb tshwj xeeb, nrog SDRAM SO-DIMMs tsuas muaj 144 tus pins, thaum DDR SO-DIMMs muaj 200 tus pins. Tsis tas li ntawd, phau ntawv nco muaj ob lub interfaces, MicroDIMM thiab Mini Registered DIMM. Lub DDR ntawm MicroDIMM chaw nres nkoj yog 172pin, thiab DDR2 chaw nres nkoj yog 214pin. Mini Registered DIMM muaj 244-PIN chaw nres nkoj thiab feem ntau yog siv rau DDR2.
Unbuffered DIMM

Xa mus rau lub lag luam desktop yam tsis muaj buffering, yog qhov feem ntau nco module ntawm kev ua lag luam.

Thaum Ntxov SDR nco mods, nrog rau hom Buffered, tau dhau los tsis tshua muaj. Buffered memory module thiab Registered memory module hais tom qab tsis yog tib yam, Buffered memory module yog qhov chaw nyob thiab tswj cov teeb liab los ntawm qhov tsis, tsis muaj sijhawm hloov pauv (tsis muaj latency yog qee qhov); Lub Registered memory module khaws chaw nyob thiab tswj cov teeb liab thiab ua rau cov zis thaum lub moos tom ntej tuaj txog.
Sau npe DIMM

Nws qhov chaw nyob thiab tswj cov teeb liab los ntawm kev sau npe, lub moos los ntawm PLL theem ntsuas phoo, tso rau hauv qhov chaw ua haujlwm thiab kev lag luam server.

Registered memory modules, piv nrog Unbuffered memory modules, qhov zoo yog tias nws yooj yim dua kom ua tiav lub peev xwm siab dua thiab ruaj khov ntawm ob theem module thiab qib motherboard, tab sis rau ib qho kev nyeem thiab sau ntawv nkaus xwb, nws yuav lag ib lub voj voog.

LRDIMM (Load - Txo DIMM)

Hloov chaw siv cov ntawv sau npe nyuaj, LRDIMMs siv cov buffers yooj yim. Buffering txo cov hluav taws xob thauj khoom ntawm lub hauv paus motherboard, tab sis muaj kev cuam tshuam me ntsis rau lub zog thiab kev ua haujlwm nco. Tsis zoo li RDIMMs thiab LRDIMMs, uas tso cai rau cov chaw tsim khoom lag luam tso ntau cov qauv ntawm txhua lub cim xeeb channel. Raws li qhov tshwm sim, LRDIMMs tau tsim los kom muaj qhov ntim loj ntawm lub cim xeeb yam tsis muaj tus nqi latency siab.

Los ntawm kev siv cov thev naus laus zis tshiab thiab kev ua haujlwm qis dua, LRDIMM tuaj yeem txo qhov kev thauj khoom thiab lub zog siv ntawm lub tsheb npav neeg rau zaub mov, thiab pab kom lub tsheb npav neeg rau zaub mov kom ua tiav kev ua haujlwm ntau dua thiab ua kom muaj peev xwm txhawb nqa lub cim xeeb.

Kev sib piv:
1. Los ntawm qhov kev xav ntawm tus nqi, RDIMM kuj yog nruab nrab. Lub peev xwm me me UDIMMs pheej yig dua, tab sis vim yog cov txheej txheem tsim khoom siab, UDIMMs muaj peev xwm tseem kim dua li RDIMMs. Lrdimms kim dua RDIMMs thiab UDIMMs.

2. Los ntawm kev pom muaj peev xwm, tsuas yog LRDIMMs tuaj yeem txhawb nqa qhov siab tshaj plaws tag nrho lub peev xwm. Txawm li cas los xij, lub peev xwm nco tau xav tau rau cov ntawv thov loj feem ntau tuaj yeem ua tiav los ntawm kev siv RDIMMs.

3. Los ntawm qhov kev xav ntawm lub ntsiab zaus, tsuas yog RDIMM txhawb 1.6GHz tam sim no, uas tuaj yeem muaj ntau dua bandwidth thiab teev qeeb.

4. Los ntawm qhov kev xav ntawm kev ncua, txawm hais tias UDIMM muaj qhov ncua sij hawm tsawg tshaj plaws ntawm tib zaus, RDIMMs tuaj yeem txhawb nqa 1.6GHz, thiab siv ntau zaus kom txo qis.

5. Los ntawm qhov kev xav ntawm kev siv hluav taws xob, LRDIMMs yog qhov siab tshaj, thaum RDIMMs thiab UDIMMs yog qhov qis tshaj.
