OCZ 4GB DDR2 PC2-6400 VP Platinum Dual Channel

In our final test, we opted to run FutureMark's 3DMark06 default benchmark to see what impact, if any, the memory speed and quantity had on the results.

In this test, we saw no major variations between having 1, 2 or 4GB of memory installed and even the frequency had no impact on this test.  This demonstrates how much the test relies on CPU and the graphics card used rather than what type and how much memory was installed.


In our final round of testing, we delved into the overclocking arena to see what kind of extra headroom the Platinum series was hiding.  First we set the memory for 800MHz in the BIOS and then dropped the CPU multiplier to x5 to make sure the CPU wasn't the cause of a failed overclock.  Lastly, we maxed out the DDR voltage at 2.5v.  Next, we sought to find the highest stable speed with the rated timings of 5-4-4-15.

Ultimately, the highest bus speed we could hit was 227MHz, which helped the OCZ Platinum series move from 800MHz to 908MHz, a gain of 108MHz or 11.8%.  Next, we relaxed the times to 6-6-6-18 and continued to raise the bus speed to see just how high we could go.  In the end, we managed to hit an impressive 256MHz, which pushed the memory up 224MHz to 1024MHz, a gain of 28%.  There is no arguing that these modules are built for speed but it's up to your individual taste regarding which method is best.  Our personal preference is the highest speed with the tightest timings.
