The Mushkin memory that's up for testing today is its 2GB HP3-10666 (DDR3-1333) memory kit. By default the memory is rated to run at 1333 MHz with low CAS latency timings of 6-7-6-18, on a voltage of 1.7-1.8V. Much of the DDR3 memory on the market has a CAS Latency of 7 or 8, so Mushkin's memory here will perform faster clock for clock compared to the competition!
If you stock your enthusiast grade PC with memory featuring tight timings, that usually means forgoing high operating memory speeds for net performance. In other words, users looking at the Mushkin HP3-10666 should not expect to break technical speed records. That doesn't mean this modules are going to be slow though... quite the contrary in fact.
