Kedu ka PC gị na nchekwa na Latency si emetụta arụmọrụ
Oge ọsọ nke ebe nchekwa ga-ekpebi ọnụego nke CPU nwere ike ịhazi data. Nke dị elu karịa ọkwa elekere na ebe nchekwa ahụ, ngwa ngwa ka usoro ahụ nwere ike ịgụ ma dee ozi sitere na ebe nchekwa ahụ. A na-echekwa ebe nchekwa ọ bụla na ọnụego elekere kpọmkwem na megahertz na ebe nchekwa ahụ na-agwa CPU okwu. Usoro ncheta ohuru ohuru amalitela izo aka na ha dabere na bandwidth data data nke nchekwa na-akwado nke nwere ike ime mgbagwoju anya.
A na-ezo aka na nsụgharị DDR niile site na ọkwa elekere, mana ọtụtụ ndị na-emepụta ebe nchekwa na-amalite na-ezo aka bandwidth nke ebe nchekwa ahụ. Iji mee ka ihe mgbagwoju anya, ihe nchekwa a nwere ike deputa ya na ụzọ abụọ. Usoro mbụ na-edepụta ebe nchekwa ahụ site na ọsọ ọsọ elekere na mbipute DDR nke eji. Dị ka ọmụmaatụ, ị nwere ike ịhụ aha 1600MHz DDR3 ma ọ bụ DDR3-1600 bụ nke bụ nanị ụdị na ọsọ jikọtara.
Ụzọ ọzọ nke ịmepụta modulu ahụ bụ site na njikwa bandwit ha na megabytes kwa nke abụọ. Ncheta 1600MHz nwere ike ịga ọsọ ọsọ nke 12.8 gigabytes kwa nkeji ma ọ bụ 12,800 megabytes kwa nke abụọ. Nke a na-akwadozi nke a site na nọmba mbipute e tinyere na PC. N'ihi ya, DDR3-1600 ebe nchekwa na-ezo dị ka PC3-12800 ebe nchekwa. Nke a bụ nsụgharị dị mkpirikpi nke ụfọdụ DDR na-echekwa nke nwere ike ịchọta:
- DDR3-1066 = PC3-8500
- DDR3-1333 = PC3-10600
- DDR3-1600 = PC3-12800
- DDR4-2133 = PC4-17000
- DDR4-2666 = PC4-21300
- DDR4-3200 = PC4-25600
Ugbu a, ọ dịkwa mkpa ịmara ihe kachasị ọsọ nke ebe nchekwa gị nwere ike ịkwado. Dị ka ọmụmaatụ, ọkpụkpọ gị nwere ike ịkwado 2666MHz DDR4 ebe nchekwa. Ị ka nwere ike iji 3200MHz echetara ebe nchekwa na processor ma motherboard na CPU ga-agbanwe ọsọ ọsọ ala iji mee ihe n'ụzọ dị irè na 2666MHz. Nsonaazụ bụ ebe nchekwa na-agba ọsọ na-erughị ike bandwit ya. N'ihi ya, ịchọrọ ịzụta ebe nchekwa kachasị mma na kọmputa gị.
