Care ar fi diferenta intre 1 banc de memorie si 2 pe nForce2

Diferenta de performanta este mare daca nu se foloseste decat 1 banc de memorie?
Vreau sa-mi iau o placa be baza cu nForce2 si bani de 2 module de 256 nu am bani. Vreau sa-mi iau mai intai 1 dimm 256 CL2(Corsair, ca s-au ieftinit) iar mai incolo si al doilea dimm. Poate ceva rezultate comparative?

mda ... buna idee 8)
sa vedem ce putem face...

E prea mult daca va cer sa scrieti un mic rezumat si in acest subiect ?
Ca nu au venit la noi ultimele doua exemplare ale revistei ! :x
Trebuie sa ma abonez, numai ca-s lenes sa ma duc la posta ...

Ideea e ca, cu doua module de memorie se poate activa Dual Channel DDR-ul, care mareste performantele sistemului cu vreo 3-5% ... daca e doar un modul, nexam Dual Channel DDR, nexam cresteri de performanta

Beyond3D a analizat o placa de baza Leadtek cu nforce2, cu un dimm si cu doua

Up: Aici poti gasi aplicatiile care pot profita de pe urma tehnologiei dual-channel. Tipi de aici sunt cam optimisti:

"But in fact, today's AGP 8X/Serial ATA/USB 2.0 platforms are already memory-bandwidth-starved, and any architecture that can keep these components supplied with data without having to borrow bandwidth from the CPU is a good thing. This has been proven by benchmark tests of the nForce2, which shows clear performance gains when switched from single- to dual-channel mode."

Down:
Aici se concluzioneaza cum dual-channel nu aduce decat un spor de performanta de maximum 2% (placa testata: Asus A7N8x):

"The highly hyped dual bank DDR technology is nearly useless in reality. From the figures above, it offers around 0~2% performance gain over single bank configuration. The EV6 bus is having a hard time supplying the required bandwidth, on the other hand, the P4 CPUs could benefit from the dual bank DDR configuration due to the QDP architecture. Note: The dual bank DDR would become useful if onboard graphics card is utilized."

Inclin spre al doilea tip de concluzie... mai multe link-uri mai pe seara.

PS Legat de linkul lui dorin, stiti de oferta excelenta (din punct de vedere al raportului pret/performanta) de la Caro? "LEADTEK NFORCE2 WINFAST K7NCRD + 2 x 256 MB CORSAIR VALUE SELECT 266 (Fuctioneaza si la Cas 2, 5-2-2). Pret: 166$ (fara TVA)"

am testat placa de la Leadtek cu nForce2-GT.
si cu modul si cu doua.
si cu grafica integrata si cu placi video AGP. (GeForce 3Ti 200 si GeForce2MX400).
rezultatele in nr viitor 41

oricum diferentele dintre un modul si doua este destul de mica...

Mersi pt. informatii.
Inca o subiect de articol ar fi testarea pe un nForce2 un proc cu bus la 133 si dim pc 2100 CL2 si un proc la care sa-i satati bus-u la 166 si memorii pc2700 CL2. Asta ca o sugestie. :oops:
