Txoj kev rov qab los rau xyoo 2014, Corsair's Dominator Platinum nco yog qee qhov kev lag luam zoo tshaj plaws uas yuav tsum tau muab - hom tshiab DDR4, ntsuas ntawm qhov nrawm txog li 3300MHz thiab muaj nyob rau hauv cov khoom siv plaub-stick tag nrho ntawm 16GB ... rau tsuas yog $ 900. Txij thaum ntawd los, muaj peev xwm tau nce mus ntxiv, nrog 8GB thiab 16GB sticks tam sim no dhau los ua qhov qub, thaum cov nqi tau poob qis. Ntau zaus kuj tau maj mam nce mus rau lub sijhawm, thiab xyoo 2020, 3200MHz RAM yog suav tias yog lub hauv paus ceev rau kev tsim cov peev nyiaj, nrog 3600MHz yog qhov kev xaiv ua haujlwm siab uas tsis muaj nqi hauv ntiaj teb. Niaj hnub no, peb tab tom sim cov kauj ruam tom ntej - 4000MHz RAM - kom pom qhov txiaj ntsig zoo ntxiv uas peb tuaj yeem nrhiav tau.
Niaj hnub no cov kev tsom xam nyob ib ncig ntawm Intel kev sim platform, qhov twg peb tau sim cov khoom siv 4000MHz RAM ntawm zaus ntawm 3200MHz txog 4000MHz hauv 200MHz nce ntawm cov khoom siv ntsuas CL19 lub sijhawm. Peb kuj tau dipped peb cov ntiv taw hauv dej ntawm RAM overclocking, nrog cov txiaj ntsig ntawm 4200MHz overclock, ntxiv rau nruj CL16 lub sijhawm los ntawm 3200MHz txog 4000MHz. Peb kuj tau sim peb cov khoom siv RAM uas peb muaj ntawm tes ntawm lawv qhov chaw XMP kom pom seb koj puas tuaj yeem cia siab tias yuav muaj kev hloov pauv loj ntawm RAM los ntawm cov tuam txhab sib txawv ntawm tib qhov ntsuas ceev. Qhov ntawd yog kaum plaub qhov kev teeb tsa sib txawv ua ke, uas yog vim li cas qhov kev sim no tau siv qee lub sijhawm los ua.
Raws li ib txwm muaj, kev ua si yuav yog peb lub hom phiaj tseem ceeb, nrog rau peb lub npe uas peb nyiam sim, tab sis peb kuj snuck hauv qee cov ntsiab lus tsim ua haujlwm kom pom tias RAM ntau dua lossis lub sijhawm nrawm tuaj yeem ua qhov txawv ntawm lwm qhov xwm txheej ib yam nkaus. Peb kuj tau sau cov lus qhia ceev ceev rau cov neeg siv khoom RAM, muab qee cov cai yooj yim ntawm tus ntiv tes xoo thaum koj nyob tom tsev lossis hloov kho lub PC gaming.
Rau peb qhov kev sim, Corsair muab ob 8GB sticks ntawm lawv Vengeance RGB Pro DDR4-4000MHz RAM, nrog XMP 2.0 lub sijhawm ntawm 19-23-23-45 ntawm 1.35V. (Cov khoom siv tam sim no muag rau £ 180 hauv UK thiab $ 185 hauv Asmeskas, tab sis koj tuaj yeem nrhiav pheej yig dual-channel 16GB 4000MHz CL19 cov khoom siv rau ib puag ncig $110 / £115 Yog hais tias koj tsis fussed txog RGB teeb pom kev zoo los yog ib lub hom phiaj.) Ua tib zoo saib, cov tshwj xeeb sticks muaj ib tug Corsair version tus naj npawb ntawm 4.31, qhia tias lawv siv Samsung B-Die nco chips. Qhov no yog RAM hom kev xaiv rau cov neeg nyiam Ryzen thaum ntxov vim qhov ua tau zoo dua nws muab, thiab nws yuav tsum ua tau zoo ntawm Intel platform thiab. Tau kawg, kev suav nrog RGB LEDs nyob rau ib tus zuj zus ntawm Corsair RGB Pro yuav muab kev txhawb siab rau kev coj ncaj ncees hauv lub sijhawm ntev.
Wb tham me ntsis txog txoj kev. Benchmarking yog txhua yam hais txog kev tshem tawm ntau qhov sib txawv raws li qhov ua tau kom ntseeg tau tias koj cov txiaj ntsig zoo ib yam. Tej zaum yuav muaj qee qhov sib txawv ntawm qhov sib txawv, tshwj xeeb tshaj yog thaum kuaj hauv-kev ua si ncej-tus nqi, tab sis qhov tseeb qhov no yuav raug txo kom ntseeg tau tias koj cov txiaj ntsig tau rov ua dua thiab sawv cev. Qhov no yog qhov tseem ceeb rau kev sim daim npav daim npav, tab sis mus ob npaug rau CPU kuaj qhov chaw sib txawv ntawm ib puag ncig lossis ib qho haujlwm tseem ceeb pib hauv keeb kwm yav dhau tuaj yeem hloov pauv koj cov txiaj ntsig. Kev ntsuam xyuas RAM yuav siv qhov no mus rau lwm qib, vim tias peb cia siab tias yuav pom qhov kev ua tau zoo ib feeb nce raws li qhov zaus maj mam nce.
Txhawm rau muab qhov zoo tshaj plaws rau peb tus kheej kom tau txais txiaj ntsig zoo, peb yog li ua tsis taus qhov kev coj tus cwj pwm zoo li qub ntawm 9900K hauv peb qhov kev sim ntsuas, ntsuas nws rau nws txhua tus tub ntxhais turbo zaus ntawm 4.7GHz nrog ntau cov tub ntxhais txhim kho kom ntseeg tau tias lub zog txwv tsis pub dhau. ua ib qho teeb meem. Peb AVX offset tau teeb tsa rau 0, rau ib qho haujlwm AVX hauv peb qhov kev npaj ua haujlwm, thiab CPU kiv cua ceev tau kaw rau 100 feem pua los xyuas kom meej tias qhov kub thiab txias tsis ua rau lub tshuab ua kom lub zog ntawm txhua qhov chaw.
Nrog rau 9900K, peb tau siv cov khoom siv siab kawg thoob plaws, nrog rau Gamer Storm Castle 240mm AiO, Asus Maximus XI Extreme motherboard thiab 1TB ntawm NVMe ceev ceev los ntawm XPG. Peb daim npav duab yog peb qhov kev xaiv ib txwm muaj rau kev sim CPU, Nvidia GeForce RTX 2080 Ti Founders Edition.
Nrog cov ntsiab lus no nyob rau hauv qhov chaw, peb npaj txhij mus dhia rau hauv thawj feem ntawm peb cov txiaj ntsig: cov ntsiab lus tsim kev sim. Peb kuj tseem yuav saib seb txhua qhov ntawm peb 14 qhov kev teeb tsa sib txawv li cas ntawm qhov kev ua tau zoo ntawm cov khoom siv raw, yog li teeb tsa qee qhov kev txwv siab rau peb cov kev xeem tom ntej.
