Kingston HyperX 2GHz DDR3 3GB (3 x 1GB) Triple-Channel Memory Kit

Cinebench R10:

CINEBENCH is based on MAXON's commercial animation software, CINEMA 4D, which is used extensively by studios and production houses worldwide. The program is capable of scaling up to 16 CPUs, is multithreaded, and has 64bit executables.

For the multithreaded test, there is about a 4% gain from 1333 MHz to 2000 MHz, so clearly memory speed does have an impact on performance.

Mathematica 7:

Wolfram Mathematica does computation, modeling, simulation, visualization, and so much more. It is a very robust product that has been around for as long as I can remember. The built-in benchmark program runs the following tests and reports a score along with the time it took to process.

• Data Fitting
• Digits of Pi
• Discrete Fourier Transform
• Eigenvalues of a Matrix
• Elementary Functions
• Gamma Function
• Large Integer Multiplication
• Matrix Arithmetic
• Matrix Multiplication
• Matrix Transpose
• Numerical Integration
• Polynomial Expansion
• Random Number Sort
• Singular Value Decomposition
• Solving a Linear System

Here we see about a 6% increase in performance between 1333 MHz & 2000 MHz memory speeds, shaving off almost an entire second from the benchmark.
