Frequency Performance: Memory
Now when keeping the memory timings the same across the board (CAS9-9-9-20). We will only adjust the memory frequency to see what kind of impact this has on a Core i7 setup.
When testing the memory bandwidth performance using SiSoftware we see fairly consistent performance gains from 13GB/s to an impressive 27GB/s.
With EVEREST the write performance is much the same for the DDR3-800/1066 and 1333 configurations, while the DDR3-1600 memory delivers a significant performance increase. The read performance, on the other hand, continues to increase with the memory frequency.
The SuperPI calculation times are only slightly reduced when using higher clocked DDR3 memory, though the performance gains are hardly significant.
