We move up from the Patriot G Series kit we looked at recently to find out how the top of the line PC3-16000 Viper II kit goes.

Operating System: Windows Vista SP1 64-Bit


Drivers: ForceWare 185.65


Today we'll see how the Patriot Viper II series PC3-16000 kit goes against a number of other modules. We've included two other PC3-16000 kits, the G.Skill Trident Series 6GB kit that comes in with slightly more relaxed 9-9-9-24 timings and the Dominator GT kit from Corsair which carries with it the same 8-8-8-24 setup.


We've also included the PC3-12800 kit that we looked at from Patriot the other day which uses a lower clock speed and more relaxed timings. This will let us find out just what kind of extra performance you would get by buying the higher clocked Viper II set verse the lower clocked G Series one.

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.

We find as usual that performance between all modules is quite similar. The Patriot kit did manage to throw us our quickest 1024M wPrime score, though.
