Cinebench 9.5

Notes
Going from DDR2-667 CAS5 to DDR2-1066 CAS5 slashed eight seconds off our encode time for both Core 2 Duo and Core 2 Extreme. Adjusting memory timings also played tangible dividends, going from CAS 5 DDR2-800 to CAS3 modules cut encode time by six seconds for the Core 2 Duo, while DDR2-800’s performance improved by four seconds for Core 2 Extreme. In fact, the lower latency DDR2-800 modules were faster at encoding than the higher latency DDR2-1066 modules. We saw nice improvements in DivX conversion as well, although MP3 encoding is probably close enough to be within the margin of error.
