I found this really cheap pair of patriot 8gb ram for 30 dollars on shell shocker, but I already have a pair of kingston 4gb. They have different brands, but same latency and same voltage. Another thing though, I am using my kingston at 1333 mhz, but they are actually 1600mhz. the 8gb patriot rams are 1333mhz, will that conflict? Thanks for the help
