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)

 

Motherboard(s): GIGABYTE HD 4870 512MB (Supplied by GIGABYTE)

 

Hard Disk(s): Western Digital 300GB Velicorapter (Supplied by Western Digital)

 

Operating System: Windows XP Professional SP2, Windows Vista SP1 64-Bit

 

Drivers: Catalyst 8.12

 

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.
