When it comes to overclocking memory we do have to mess around with the base clock slightly and this can result in lower or higher MHz in an overclocked setting. With that said, we try to keep the MHz as close to the 4GHz clock that we base our system off.
Instead of the 20 x 200 4GHz setup that we normally run, our Patriot modules when clocked to 1724MHz meant we dropped the multiplier to sit with the 216 BCLK. In the end we finished up with a 19 x 216 setup which results in a 4.1GHz CPU speed for the Patriot modules when at 1724MHz. Just keep this in mind when it comes to looking at results that mainly use the CPU more so than the memory.
For comparisons sake we've also included the Corsair Dominator GT kit we looked at just the other week which carries not only a higher stock clock, but also lower timings. We'll see what kind of value the Patriot kit we have here today offers when compared to this Corsair one which is $329 (or just over 3x the price).

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.
What we see under wPrime is that the overclocked Patriots manage to outperform the other setups. This is due to the test mainly taking advantage of the CPU clock.
