Test System Setup

Processor(s): Intel i7 920 @ 4GHz (200MHz x 20)

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

With a new CPU in hand that we organized specifically for our new memory testbed along with a new graphics card that's going to be used in all our memory articles, we were ready to go.

What we've done today is set the modules to their default 2000MHz setup which is 8-8-8-24; we've also clocked them down to 1600MHz while using the same CPU speed and moved to the JEDEC timings which are 9-9-9-24. We'll see what the extra MHz does for overall performance. This is a good setup since the CPU speed is exactly the same and the only difference is the memory 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.

wPrime is quite CPU orientated so what we see here is no real difference between the two setups.
