i have one 2gb ddr3 irvine stick with 667MHz and i am thinking about buying a kingston HyperX Fury 8gb ddr3 ,1866Mhz ram....so can i use both or remove the irvine RAM .........what will be the consequences if i use both????
 
Solution
To get the best performance, remove the Irvine RAM as your system will down clock and run the RAM at the speed of the slowest stick for stability.
