Summary: Very pleased with delivery, arriving sooner then expected. Was rather sad to find out my Motherboard couldn't use the cards correctly though and caused bluescreening, but that was all on me. Found no issues with the part.
Summary: Upgraded my system with (2) of these modules and an 6 core AMD FX series CPU. Realized a considerable improvement in performance and shorter boot up speed. Have used Corsair RAM in the past and have found it to be very reliable. Would have liked to have seen the CAS latency around 8 or 9 instead of current 10 but for normal use it is acceptable.
