I started the testing at stock speeds and with one of the most widely used benchmarks, SiSoft Sandra. Moving up to 800 and all the way to the max attainable overclock I was able to acheive a score of 1014, you can see the extra bandwidth getting served up by these chips. 9546 MB/s overclocked versus the 7107 MB/s stock speeds.
That is over a 2000 MB/s upgrade for a few extra volts and some mild tinkering. I had to push 2.4v to get up that high, but apparently these chips are rated for that much power. To top that off I was able to do this at the stock timings of 5-4-4-12 @ 2T, anything less and my system would not post.
With SuperPi finding Pi to the one millionth digit we can see that it too favors the MHZ increase.
PiFast is very similar to SuperPI in that it benefits greatly from the increase in memory megahertz. I had the Chudnovsky method calculate to the ten millionth digit with a 1028k FFT
The 3dmark05 and 06 benchmarks that I ran show an increase, however slight, in performance. This is mainly due to the fact that they are stressing the video card and the cpu. I ran both of these at 1024*768
To show off some of Crucials strengths in the enthusiast market, I have compiled a few benchmarks of what an enthusiast might be playing today. These games consist of Prey, Far Cry, and F.E.A.R. These games were all run at 640*480 to minimize any impact on the video card.
I chose to run Prey to show how this memory would run on the d3 engine. Doom3, Quake4, and Prey all run on this engine and the most recent variable would most likely be the one that is played currently. Prey responded quite favorably with the increase in memory bandwidth.
Far Cry, while being a bit outdated at this point, still proves to be one of the hefitest games to run on almost any system. Crytek's game engine favors the extra oomph I have provided.
F.E.A.R. has it's own built in benchmarking system that I used. I realize I hit a ceiling of 183fps, however all the low and mid range frames decreased showing that this Crucial memory helps out in all gaming situations.
