It's not taht the rams are from Ballistix that they do what they do with everyoen else, just could be that on eof the sticks was a bit dodgey from the start and failed now... secondly the board overvolts the ram wth 0.1 ( keep that in mind) , Same for CPU PLL Voltage even when set at 1.5 it's 1.6... I just think your CPU voltage is way too low to be stable at any speed... 1.218 will givbe around 1.2 under load , my CPU has a VID of 1.215, runs fine at that speed at stock till aroudn 3ghz mark , from there on it needs 1.25Vcore set in bios to be Orthos stable, 3.2-3.4 requires about 1.3150, 3.6 around 1.475...

also id you disable transaction booster and static read control you can go low on the NB voltages... though once you start tweaking there the NB here needs around 1.43NB voltages to run stable 400FSB (mine is watercooled so temps stay within 35°C range) also make sure you place a fan over the NB to keep it well cooled...

If I was you I would look in the Intel thread and look up the Asus Maximus Formula SE thread, stat from scratch and start to dig there for more info...
