Damn, nice time! That's what i was running with 9-12-11-21-1T@2666mhz with x52/x49! (same kit)
Dialing in 2800mhz now, can't get it to boot past 2828mhz on mine though which is annoying. Sitting at 9-12-12-21-1T@1.85v and going through tertiary's. Looking forward to getting some 4/5 gig runs done once finished and posting some screens! Quick question though, i can drop tRAS lower than 21, i.e, is it advised or does the cas+tRCD rule come into play?
