De ce AIDA32 arata frecventa memoriei la jumatate?Eu am o memorie DDR333 pe care o arata ca merge la 166mhz si una DDR400 pe care o arata la 200mhz.CRE E REALITATEA?Are ceva ca am doua placi de frecvente diferite?

mai intai versiunile mai vechi de aida nu au stiinta de "divaisurile" aparute dupa lansarea versiunii in cauza, si ddr nu inseamna ca se dubleaza viteza memoriei, ci ca memoria aia "stie" sa faca transfer de date pe ambele fronturi ale semnalului de tact, nu doar pe cel crescator sau descrescator, cum fac memoriile sdram si edo/fpm... iar castigul de performanta nu e chiar 100%, ci e ceva mai mic... cam 75-80%, functie de calitatea memoriei (latenta'n'stuff)...

sdram inseamna single data front ramddram inseamna double data front ram. deci datele se transfera si pe frontul crescator si pe frontul coboritor.practic, memoria tot la 166/200 sau cit or fi merge. insa nu se mai transfera datele de 166/200 de ori pe unitatea de masura ci de 2x166/200 ori.si in plus o chestie de marketing...
