Super PI

Super Pi calculates the infamous number PI from 16 thousand all the way up to 32 million digits! For our testing purposes, we decided on two million digits which takes 20 iterations. Super Pi then spits out the time (in seconds) that it took to do the calculations. Obviously, the lower the number, the better.

When the memory is at its full 500 MHz, Super PI's calculation time drops by 25%. Overall, you should expect a 20-25% increase in performance if you use PC4000 rather than PC3200 which matches up quite nicely with the 25% increase in MHz from 400 to 500 MHz.

Conclusion

In our testing we found that Corsair's PC4000 had a 20-25% increase in performance over PC3200 speeds. However, do note that the CPU speed increased along with the memory. With the memory at 400 MHz, the processor was at it's stock 2.4 GHz; with the memory at 500 MHz, the processor was kickin it at 3.0 GHz. Fortunately our processor was able to handle the intense overclocking. While the timings are rather lax, they are required to reach such high speeds.

While this memory is damn fast as is, don't expect to get much more than the stock 500 MHz out of it. Overclocking was a bit of a disappointment with only a 10 MHz overclock from 500 MHz to 510 MHz.

If you are an AMD user, you should probably pass on the PC4000 and stick with something your motherboard can take advantage of. Intel users however, will definitely want to look at this memory, especially if you have an i865/i875 based motherboard.

Pros

Damn fast!
Great for overclocking your P4

Cons

Not much room for overclocking
Not the best choice for AMD systems
