Today we'll have a look at the G.Skill 6GB kit at it's stock speeds as well as with the overclock we achieved (1705MHz) and at 1200MHz which equates to a 6x memory ratio with the CPU at 200MHz QPI.

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 only time we see much movement on wPrime is when we overclock the modules to 1705MHz. However, the boost in performance is probably more so from the extra 200MHz on the CPU rather than the extra MHz on the memory.
