Jeg har lige leget med mit Asus SLI bræt, men der er en ting der undre mig.
Der er forskel på min båndbrede når jeg clocker, ved godt at der skal være forskel, men dette er i negativ retning jo højre min fsb kommer op.
fsb 265*10 giver ca. 7150 i sisoft
fsb 311*8,5 giver ca. 6850 i sisoft
burde det ikke være omvendt, jo højre fsb jo højre båndbrede eller er det mig der har misforstået noget.

Hvis maskinen ikke er helt stabil ved 311 mhz regner den forkert og er derved nød til at regne flere gange på det samme og yder derved dårligere.
#2
kan måske også være fordu du bruger halv multi. brug hele multi så mener jeg det hele er lidt hurtigere

Fuldstændigt rigtigt #2 derfor :
dvs ved 8.5 uderclockes dine ram selvom at cpu-z siger noget andet, det kan ikke ses andre steder end på resultatet af båndbredden

ja derfor.. men også:
"Now that AMD deviated from the norm and implemented the memory controller on the CPU, multipliers are crucial in providing high bandwidth. During the era of Socket A, it was always about lowering the multipliers and raising the FSB. Generally, the higher the FSB, the higher the system bandwidth. Of course latencies also come into play, but let's just keep focus on the general rule of higher frequency equals higher bandwidth. This means that there was no difference in memory bandwidth when running 11x200FSB or 10x200FSB. The CPU horsepower was different, but the memory bandwidth stayed the same. This is no longer the case with Athlon64 CPUs. Multipliers affect the memory bandwidth significantly, which means that a higher multiplier results in higher bandwidth."
