Ngaba i-Latest Generation ye-PC Memory Impact PC ininzi?
Imemori yeDDR3 isetyenziswe kwihlabathi lePC iminyaka emininzi ngoku. Enyanisweni, kubonakala ukuba yimizuzu emibini emininzi yememori yokukhumbula imilinganiselo. Oku kuye kwaba ngumthengi kubathengi njengoko kuthethwa ngentengo yeememori ezifikelelekayo kodwa kubhekiselele kwiminyaka emibini edlulileyo ukuba iikhomputha zethu ziye zithintela ngesivinini sememori. Oku kubonakala ngokucacileyo njengoko siqala ukwenza imisebenzi enzima kakhulu efana nokuhlelwa kwevidiyo yedesktop kunye nokusetyenziswa ngokukhawuleza njengendlela yokuqhuba ngokusemgangathweni .
Ngokukhutshwa kwe-chipset ye-Intel X99 kunye ne-Haswell-E kunye nabapro processors base-Intel Core ngoku-6, i-DDR4 ngoku ibe ngumgangatho osetyenziswayo kwiikhompyutheni zobuqu. Imigangatho yaveliswa emuva ngo-2012 kodwa ibe yiminyaka emininzi kule migangatho ekugqibeleni yenza ukuba ithengise. Ngoko makhe sifumane ukuba yintoni enye utshintsho le standard memori eyoyizisa kwi-PC.
Ixesha elikhawulezayo
Kanye njengoko kungeniswa kwemigangatho ye-DDR3, i-DDR4 ngokuyinhloko ikulingana ngesivinini esheshayo. Ngokungafani ne-DDR2 ukuya kutshintsho lwe-DDR3 nangona, ukunyuka kwejubane kuya kuba yinto encinci kuba sele ithathe ixesha elide ukuba i-DDR4 yamkelwe yoshishino. Imemori ye-JDEC ye-JDEC esheshayo imemori ngoku isebenza nge-1600MHz. Ngokwahlukileyo, imemori entsha ye-DDR4 iyaqalisa ngo-2133MHz, eyinqanaba lokunyuka kwamaxabiso e-33%. Ngokuqinisekileyo, kukho imemori ye-DDR3 efumaneka ngesivinini ukuya phezulu kwe-3000MHz kodwa le nto ikhunjulwe imemori ehamba phambili emgangathweni kunye nezidingo zamandla aphezulu. Imigangatho ye-JDEC ye-DDR4 iphinda ichaze kwi-speed ye-3200MHz ephindwe kabini umda we-DDR3 1600MHz okhoyo.
Njengokuba kunjalo nezinye izilwanyana, ukunyuka kwenyuka kuthetha ukunyuka kwama-latencies. I-Latency ibhekisela ekubeni kuthatha ixesha elingakanani umlawuli weememori ukuba athathe umyalelo wokufikelela kwimemori kwaye ngokuqinisekileyo ufunde okanye ubhale kwiimodyuli zeememori. Ngokukhawuleza kunokuba imemori ifike, umjikelezo ojikelezayo uthabatha ukuthatha umlawuli ukuwuqwalasela. Le nto ihamba ngeyure ephakamileyo, i-latence eyandisiweyo kaninzi ayichaphazeli ukusebenza ngokubanzi ngenxa yokunyuka komda wendlela yokuthetha idatha kwimemori kwi-CPU.
Ukusetyenziswa kwamandla aphantsi
Amandla asebenzisa iikhomputha yinkxalabo enkulu xa ubheka kwi-market computer. Amandla angaphantsi atshiswayo, ixesha elide liyakwazi ukusebenza kwiibhetri. Njengoko kunye nesizukulwana ngasinye sememori ye-DDR, i-DDR4 iphinda iyanciphise inani lemandla efunekayo ukuze isebenze. Ngeli xesha, amazinga ombane ayehlile ukusuka kwi-1.5 volts ukuya kwi-1.2 volts. Oku kungabonakali kuninzi kodwa kungenza umehluko omkhulu kunye neenkqubo zekhompyutha. NjengoDDR3, i-DDR4 iya kufumana umgangatho ophantsi weevili kunye nokuvumela iimfuno zamandla aphantsi kulezo nkqubo ezilungiselelwe ukusebenzisa olu hlobo lomemori.
Ngaba Ndiyakwazi Ukuphucula I-PC yam kwiD Memory4?
Emuva kwenguqu ukusuka kwi-DDR2 ukuya kwi-DDR3, inkumbulo ye-CPU ne-chipset yayihluke kakhulu. Oku kwakuthetha ukuba ezinye zeebhodi zamabhinqa ezivela kwixesha likwazi ukuqhuba i-DDR2 okanye i-DDR3 kwi-motherboard efanayo. Oku kukuvumela ukuba ufumane inkqubo yekhompyutheni yedesktop nge-DDR2 ethe xaxa kwaye uphucula imemori ku-DDR3 ngaphandle kokufaka indawo yebhodi lebhodi okanye i-CPU. Le mihla, abalawuli beememori bayakhiwa kwi-CPU. Ngenxa yoko, ayiyi kuba nayiphi na i-hardware yokuguqulela engasebenzisa zombini iDDR3 kunye neDDR4 entsha. Ukuba ufuna ukusebenzisa ikhompyutha esebenzisa i-DDR4, kuya kufuneka uhlaziye zonke iinkqubo okanye ubuncinane i- motherboard , i-CPU kunye nenkumbulo.
Ukuqinisekisa ukuba abantu abazami ukusebenzisa imemori ye-DDR4 kunye neenkqubo zeeDDR3, ipakethe entsha ye-DIMM yenziwe. Zibude obufanayo njengeedyuli zeDDR3 zangaphambilini kodwa zinenani eliphakamileyo lezikhonkwane. I-DDR4 isebenzisa iipalati ezingama-288 ngokuthelekiswa neengxelo zangaphambili ezingama-240 zangaphambili kwiinkqubo ze desktop. Iikhompyutha zee-laptop zijongana nobukhulu obufanayo kodwa nge-260-pin I-SO-DIMM ifaniswe ne-204-pin pin for DDR3. Ukongeza kwendawo yokupaka, inotshi yee modyuli iya kuba kwindawo ehlukileyo ukukhusela iimodyuli ezifakwe kwiDDR3.
