We'll have a look at how the kit from G.Skill we have here today compares against itself when overclocked, while also comparing it to the OCZ Platinum kit we looked at recently. When it comes to overclocking memory, we have to adjust the BCLK. While this gives us the ability to fine tune the MHz we get from the memory, it also adjusts our CPU speed.
We make mention of the CPU speed and BCLK used in all our graphs and we try to make sure that we mention when the extra CPU MHz is helping more than the extra RAM MHz. In saying that, just keep it in mind when looking at the results between the different setups.
Let's get started!
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 extra MHz on offer from the G.Skill modules help bring our wPrime times down. Moving up a notch again, we see the times drop back a little more.
