The Sisoft Sandra 2011 SP1x benchmark utility just came out a few weeks
ago and we have started to include it in our benchmarking. Sandra 2011 fully supports Windows 7 and Intel Sandy Bridge processors, so this utility is ideal for looking at memory bandwidth.

We ran sandra several times and consistently got a score of 14GB/s on the aggregate memory performance test with the 6GB 1333MHz dual channel memory kit that came with our ASUS K53E 15.6-inch notebook.  By just turning the system off and installing the new Kingston HyperX Plug and Play DDR3 1600MHz 8GB CL11 memory kit and powering up the system it was like we had a whole new notebook. Without even having to touch the BIOS or having to adjust memory timings and voltages our memory bandwidth was rivaling what we see on many desktop computers! The aggregate bandwidth jumped up to ~23.5GB/s as you can see in the screen shot above! That is an amazing 9.5GB/s more memory bandwidth and we accomplished that in under two minutes by removing only two screws and installing a new memory kit!
