Patriot Viper 2x1GB DDR3 PC3-15000 Review

It looks like that time of day again where the various overclocks battle it out in a handful of benchmarks. These particular benchmarks are going to be quite interesting with the various tRD values and the comparison with the high clocked DDR2 setup, let's get started with some bandwidth results.

As expected, the DDR2 setup put up a heck of a battle and looks to equal the Viper memory at the 6-6-5 clocks except in the Everest Read results where the DDR3 setups walk away. The other interesting results are the comparison between the 7-7-6 and 8-8-8 overclocked results. One of the major differences helping the 7-7-6 results is the tRD value of 6 VS 7 of the 8-8-8 numbers. There just isn't a big enough gap between the clocks at 7-7-6 and 8-8-8 because of the limitations of the P5K3-Dlx motherboard. That and this memory just clocked really well at CL7.

The ScienceMark numbers seem to echo what we saw with Sandra and Everest for bandwidth but the PCMark 05 memory suite is a bit different. It seems to favor the Viper kit in all setups and has the higher clocked Viper timing set beating the 7-7-6 timing set. This is likely due to the CPU clock differences which would indicate that PCMark 05 memory suite still bases its results on the CPU power more than the other bandwidth benchmarks ran.

The latency results are about what we should expect based on the settings and bandwidth results. Again the 7-7-6 setup beats out the 8-8-8 latency and the DDR2 latency is much greater than all the others. For those of you who still think that DDR2 is better because the timings on DDR3 are too high should just have a quick look at the graph above. It doesn't get any clearer than that.
