What is the fastest, most reliable memory to run with the p5K deluxe? I was running Mushkin Redline at stock speeds but it caused my board to not boot. I have an rma set up but I haven't sent them out to get a replacement yet. It feels more like an incompatibility issue rather than bad memory though because my buddy has the exact same sysetm and he has the same problem just not as severe. So now I am looking for another brand that I can count on. Suggestions? I've only used Mushkin for the past 7 years so I don't know anything else
