Indlela I-PC Yakho Yokumemeza Ngokushesha Ne-Latency Yithinta Ukusebenza
Ijubane lememori lizonquma izinga lapho i-CPU ingakwazi ukucubungula idatha. Ukuphakama kwesilinganiso sewashi kwimemori, ngokushesha uhlelo luyakwazi ukufunda nokubhala ulwazi kusuka kwimemori. Yonke imemori ilinganiswe ngesilinganiso esithile sewashi ku-megahertz ukuthi isikhombimsebenzisi isikhombimsebenzisi sikhuluma ne-CPU. Izindlela ezintsha zokumemeta imemori manje seziqala ukubheka kuzo ngokususelwa kumkhawulokudonsa idatha wedatha ukuthi imemori isekela engase idideke.
Zonke izinguqulo ze-DDR inkumbulo zibhekwa ngokulinganisa kwewashi, kodwa abakhiqizi abaningi benkumbulo baqala ukubhekisela kumkhawulokudonsa wememori. Ukuze wenze izinto zidideke, lezi zinhlobo zememori zingabhalwa ngezindlela ezimbili. Indlela yokuqala ibala imemori ngejubane layo lewashi jikelele kanye ne-DDR esetshenziswayo. Isibonelo, ungase ubone okushiwo ngu-1600MHz DDR3 noma i-DDR3-1600 okuyisisekelo nje futhi uhlobo oluhambelana nalo.
Enye indlela yokuhlukanisa amamojula ngukulinganisa komkhawulokudonsa wabo kumagagaytes ngomzuzwana. Imemori ye-1600MHz ingasebenza ngesivinini sezinkolelo zama-gigabytes angu-12.8 ngesigamu noma ama-megabytes angu-12 800 ngomzuzwana. Lokhu kungu-prepended by inombolo yenguqulo efakwe ku-PC. Ngakho inkumbulo ye-DDR3-1600 iphinde ibhekiswe njengememori ye-PC3-12800. Nasi ukuguqulwa okufutshane kweminye yememori ejwayelekile ye-DDR engatholakala:
- DDR3-1066 = PC3-8500
- I-DDR3-1333 = PC3-10600
- I-DDR3-1600 = i-PC3-12800
- I-DDR4-2133 = PC4-17000
- I-DDR4-2666 = PC4-21300
- DDR4-3200 = PC4-25600
Manje kubalulekile ukwazi ukuthi isivinini esiphezulu sememori esingaxhaswa ngeprosesa yakho. Isibonelo, iprosesa yakho ingase isekele kuphela kufike ku-2666MHz inkumbulo ye-DDR4. Usengasebenzisa imemori elinganisiwe engu-3200MHz ngeprosesa kodwa i-motherboard ne-CPU izoshintsha ukusheshisa ukuze kusebenze ngempumelelo ku-2666MHz. Umphumela wukuthi imemori iqhutshwa ngaphasi komkhawulokudonsa wayo ogcwele. Ngenxa yalokho, ufuna ukuthenga imemori ehambisana kakhulu namakhono akho ekhompyutheni.
I-Latency
Ukuze inkumbulo, kunesinye isici esithinta ukusebenza, i-latency. Lesi yisikhathi sesikhathi (noma imijikelezo yewashi) kuthatha imemori ukuphendula isicelo somyalo. Iningi le- BIOS yekhompiyutha nabakhiqizi bememori bahlule lokhu njengokungenani kwe-CAS noma i-CL. Ngenkumbulo ngayinye, inani lemijikelezo yokucubungula umyalo landa. Ngokwesibonelo, i- DDR3 ivame ukugijima phakathi kwemijikelezo engu-7 no-10. I- DDR4 entsha ijwayele ukugijima cishe kabili ukuthi nge-latency egijima phakathi kuka-12 no-18. Ngisho noma kune-latency ephezulu nememori entsha, ezinye izinto ezifana nesivinini se-clock ephakeme futhi ngcono ubuchwepheshe ngokuvamile abenzi bahambe kancane.
Ngakho-ke kungani sikhuluma nge-latency ngaleso sikhathi? Yebo, phansi kwe-latency ngokushesha inkumbulo ukuphendula imiyalo. Ngakho-ke, inkumbulo nge-latency ye-12 izoba ngcono kunekhwalithi efanayo nejubane lesikhathi ne-latency ye-15. Inkinga yukuthi abathengi abaningi ngeke babone noma yikuphi ukuzuza okuvela ekugcineni kwe-latency. Eqinisweni, imemori yejubane ejubane esheshayo okungaphezulu kakhulu ingaba kancane ukuphendula kodwa unikeze inani elikhulu lokukhumbula umthamo ongakunikeza ukusebenza kangcono
