I've ran everything but the kingmax stuff.. Corsair is awesome for data integrity for fsb under 150... But for awesome o/c's and data integrity try using some Mushkin Cool pc2700 I got evryone of my seti boxes running this 24/7 @ 175+ fsb, turbo settings, with the fastest ram timings without even a hiccup.. Purely the best ram I have ever bought.. Stay away from crucial.. I have had lots of bad o/c's from them.. they only tend to o/c to 146-148 tops...
Hope this helps..
