Pythagore, no offense, but your earlier posts clearly show you do not understand how to calibrate a processor correctly. We tried to offer you advice but you did not seem at all interested in accepting it. Not trying to insult you, but when even the Outlaw bashers at the AVS forum (who would love nothing more than a review trashing the 990) discredited your opinion because they see your obvious setup mistakes, you should back down and start seeking advice instead of trying to offer it.
