Patriot Sector 5 PC3-20000 (2500MHz) 4GB Kit - Test System Setup and wPrime

A 2500MHz DDR kit strolls into the labs. How do we go with it? It's 2500MHz DDR after all.

Test System Setup

We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASRock, Sapphire, Western Digital, Noctua and Corsair.

 

We had hoped to be able to run our CPU at 21 x 209, but instead we had to opt for 20 x 209 which pushed our CPU speed down to 4189MHz. Just keep that in mind when comparing the kit to some higher speed modules that carry with it a faster CPU clock.

 

As for what we compared it against, we saw how the kit went compared to a couple of other high end kits including a 2200MHz DDR Kingmax kit and a 2400MHz DDR Kingston kit.

 

Let's get started!

 

Important Note: When modules are overclocked we adjust the BCLK which not only lets us fine tune the MHz out of a module, but in turn increases the overall CPU clock speed. While we always make the effort to include the BCLK and CPU Speed in our graphs, please just make sure that you make note of these when looking at the results. In some tests that don't purely test the memory speed the extra MHz on offer from the CPU can increase the result. Of course, it's worth noting that having faster memory gives you the ability to run your CPU at a higher speed.

 


wPrime

 

Version and / or Patch Used: 1.62

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.

Due to the CPU speed being a little slower, the performance here isn't as strong when compared to some of the other kits.
