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.




Interestingly enough the Dominator GT is not as fast as the Kingston offering at stock speeds (and with looser timings) in this test, although the time difference is measured in 100ths of a second. When we push the Corsair up to 1600MHz and drop the CL to 7 and the command rate to 1T we do see an improvement, but again it is a very small gain over the Corsair and a slight drop from what the SPD sets that RAM at.

EVEREST Ultimate Edition is an industry leading system diagnostics and benchmarking solution for enthusiasts PC users, based on the award-winning EVEREST Technology. During system optimizations and tweaking it provides essential system and overclock information, advanced hardware monitoring and diagnostics capabilities to check the effects of the applied settings. CPU, FPU and memory benchmarks are available to measure the actual system performance and compare it to previous states or other systems. Furthermore, complete software, operating system and security information makes EVEREST Ultimate Edition a comprehensive system diagnostics tool that offers a total of 100 pages of information about your PC.




Our EVEREST numbers are all over the place. At stock speeds the Corsair Dominator RAM is a hair slower in reads and writes, but faster at copying data from one portion of RAM to another. When pushed to 1600MHz the Corsair wins read speed, but not at write or copy.


It is interesting to see how each type of memory usage is impacted at different speeds and timings. In all the best overall performance comes from the Corsair Dominator GT running at 1600MHZ with a CL of 7 and Command rate of 1T.
