All testing thus far was performed after setting 8-8-8-24 2T timings in the BIOS. In these charts, we take the Tweaked PC settings of 3,744 MHz core speed, 2,592 MHz NB speed, and 2,016 MHz HT link speed, and test with the four different stable memory settings mentioned earlier.
There is almost no difference seen in the CPU Arithmetic test. If anything, tighter memory timings are more important than memory frequency.
Here we see the memory bandwidth given up by decreasing the memory ratio. At the 2.66 ratio, only the slightest increase in bandwidth differentiates Auto, CAS 9, our CAS 8, and the tightened CAS 7 timings.
Our two manually-set timings lead the way, but overall, little difference is seen in the 3DMark Vantage CPU score.
The scaling in World in Conflict is almost too perfect, as tightening timings results in a single fps gain in both minimum and average fps. The one noticeable difference is the drop in minimum framerates at the slower memory frequency.
Tightening memory timings on this overclocked system has no impact on 3ds Max 2009 rendering time.
