Since we couldn't really get over 2400MHz DDR, we have only benched the kit at its default setup today. For comparisons sake we've put it against the lower latency 2250MHz DDR kit from Corsair and also see how it goes against two of the 2200MHz DDR kits we've looked at previously.
Let's get started!
Important Note: When modules are overclocked we adjust the BCLK which not only lets us fine tune the MHz out of a module, but in turn increases the overall CPU clock speed. While we always make the effort to include the BCLK and CPU Speed in our graphs, please just make sure that you make note of these when looking at the results. In some tests that don't purely test the memory speed, the extra MHz on offer from the CPU can increase the result. Of course it's worth noting that having faster memory gives you the ability to run your CPU at a higher speed.
wPrime uses a recursive call of Newton's method for estimating functions, with f(x)=x2-k, where k is the number we're sqrting, until Sgn(f(x)/f'(x)) does not equal that of the previous iteration, starting with an estimation of k/2. It then uses an iterative calling of the estimation method a set amount of times to increase the accuracy of the results. It then confirms that n(k)2=k to ensure the calculation was correct. It repeats this for all numbers from 1 to the requested maximum.
The massive MHz on offer means we've got a whole lot of breathing room when it comes to our CPU speed. Well above the 4GHz clock helps put the Corsair PC3-19200 kit well in the lead here.
