Test System Setup
Processor(s): Intel i7 920 @ 3.2GHz (200MHz x 16)
Cooling: Noctua NH-U12P (Supplied by Noctua)
Motherboard(s): GIGABYTE EX58-UD5 (Supplied by GIGABYTE)
Graphics Card(s): ASUS GTX 285(Supplied by ASUS)
Hard Disk(s): Western Digital 300GB Velicorapter (Supplied by Western Digital)
Operating System: Windows Vista SP1 64-Bit
Drivers: ForceWare 185.65
Today we'll be seeing how the A-DATA kit we have here goes at its stock 1600MHz speed and we'll also see how that compares against 2000MHz Corsair modules that have been down clocked to 1600MHz and use the JEDEC approved latencies.
We'll also be seeing how the kit compares at the stock 1333MHz that most basic i7 systems would use along with what kind of performance increase we got when the speeds are ramped up to 2000MHz.

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.
With the processor sitting at 4GHz in all setups what we see is that the performance between all configurations is very similar.
