Everest Ultimate Edition is an industry leading system diagnostics and benchmarking solution for enthusiasts PC users, based on the award-winning Everest Technology. During system optimizations and tweaking it provides essential system and overclock information, advanced hardware monitoring and diagnostics capabilities to check the effects of the applied settings. CPU, FPU and memory benchmarks are available to measure the actual system performance and compare it to previous states or other systems.

The biggest gains can be seen with the move from 800MHz to 1066MHz. P965 vs. P35 performance is pretty similar with 1066MHz sneaking just ahead of 1000MHz, and 800MHz just behind 833MHz. At the default 7-7-7-21 timings DDR-3 seems to lag just slightly behind its DDR-2 5-5-5-15 counterpart. When you move to 7-5-5-10 the DDR-3 fights back and sneaks ahead with 1333MHz giving us a little bit more speed breaking 8000MB/s. Of course 1500MHz and our increased FSB see us well over 8500MB/s.

Write speeds across the board are very similar, the good thing is that Everest is very consistent, so while there might only be 50MB/s difference it is going to be faster which again shows us that P965 vs. P35 does not have a huge amount going for it. DDR-3 at 7-7-7-21 vs. DDR-2 at 5-5-5-15 sits slightly behind, and when we get more aggressive with the DDR-3 timings doing 7-5-5-10 it is able to outperform the DDR-2. The loose timings at 1333MHz put us closer to the standard 7-7-7-21 timings at 1066MHz and the 1500MHz power clock is spitting out big numbers again thanks to the high speeds of not only the memory but the processor.

Copy speeds paint the same picture as we saw in our write tests, we can see that the move from 800MHz to 1066MHz also carries with it the biggest jump in performance.

We can again see that at the default timings at 1066MHz the latency is noticeably higher than the 1066MHz DDR-2 running 5-5-5-15 but when we move to 7-5-5-10 on the DDR-3 it outperforms the DDR-2. Even at the same speeds and a CAS rating of 7 versus 5 it is able to outperform the DDR-2 memory.
