i donīt know if it is a bios or cpu bug, but all cpus have a limit. ask the other guys that test the ES CPUs, theyīre tell you the same.

Btw i tested also one with LN2 @ 1.6v VCore but no difference, reached same clock as on air!
Thank you for the explanation. I guess, it's all nice and stable at 48x100 too, right?

Xtreme overclockers will be dissapointed. But inexperienced ones should have it easier - just raise multi till windows doesn't boot, substract one, check stability.... erm... dunno...
