Using dual channel DDR2-667 memory, the AMD Athlon64 3800+ system produces a healthy memory bandwidth of 5.5GB/s which is comparable to the latest and greatest Intel Core 2 Duo system. Overclocking the Athlon64 3800+ from 2.4GHz to 2.6GHz using a 260MHz FSB increased the memory performance by roughly 25%, boosting the bandwidth to almost 7GB/s! The Corsair ValueSelect DDR2-667 memory was also now operating at 780MHz, which helped in boosting performance.

Despite delivering similar memory performance in SiSoft2007 and PCmark2005, the Athlon64 3800+ system was somewhat squashed when it came to the MemTach performance. Here the Core 2 Duo E6700 system was far more dominant as it easily defeated the overclocked Athlon64 3800+ system.
