Salve,
ho da poco acquistato un nuovo pc, di cui ho scelto ogni singolo pezzo. Ho espressamente chiesto al negoziante 512MB di ram a 400 MHz. Come posso fare a vedere se la frequenza della ram che ho veramente 400 MHz?
Con PC Wizard 2004 la schermata relativa alla ram la seguente:

General Information :

Serial Number :
Type : DDR-SDRAM PC3200 (200 MHz)
Size : 512 Mb (2 rows, 4 banks)
Module Buffered : No
Module Registered : No
Width : 64 bits
Error Correction Capability : No
Max. Burst Length : 8
Refresh : Reduced (.5x)7.8 s, Self Refresh
Voltage : SSTL 2.5
Supported Frequencies : 133 MHz, 166 MHz, 200 MHz
CAS Latency (tCL) : 2 clocks @133 MHz, 2.5 clocks @166 MHz, 3 clocks @200 MHz
RAS to CAS (tRCD) : 2 clocks @133 MHz, 3 clocks @166 MHz, 3 clocks @200 MHz
RAS Precharge (tRP) : 2 clocks @133 MHz, 3 clocks @166 MHz, 3 clocks @200 MHz
Cycle Time (tRAS) : 6 clocks @133 MHz, 7 clocks @166 MHz, 8 clocks @200 MHz


Non riesco a capire (...o forse non voglio capire!!:mad: ) qual' il dato che indica la frequenza, potreste indicarmelo?

Type : DDR-SDRAM PC3200 (200 MHz) che X2 danno esattamente 400 Mhz

quindi vai tranquillo che sono 400 ;)
