My corsair will NOT go above 830mhz at 2.1v, 2.2v, 2.3v, relaxed timings...
Thats the RAM in my sig. And yes, it will goto 1050mhz, but that's at a different ratio, which incidentally is bloody pointless as you then have a RAM overhead on your FSB. At 1:1, it won't pass 830mhz for me.
Geil Black Dragon i heard is awesome. Ballistix even better though.
