Corsair 6GB DDR3-1866 Dominator GT Memory ReviewTue, Mar 31, 2009 - 12:00 AM
Memory Bandwidth and Super Pi
SiSoft’s Sandra 2009 is a full featured test suite with tools that permit you to test every subsystem of your computer. Today, we’re using the memory bandwidth and reporting the integer and floating point buffered memory scores. Super Pi is a mainstay within the overclocking community and scales incredibly well with increased memory bandwidth. Super Pi 1M is hardly long enough to show these improvements, but Super Pi 32M scales incredibly well with memory speed and latency.
The memory bandwidth performance was incredible and we posted above 30 gigabytes per second in both tests. Core i7 really packs a punch with memory performance with even the slow DDR3-1333C7 posting a hefty 23 gigabytes per second. Super Pi 32M scaled nicely, shaving 17 seconds while going from DDR3-1333C7 to DDR3-1866C7. Super Pi 1M dropped .12s which can be the difference between first and fifth place with this test.
