I just recently upgraded to an XP2100 B core from a XP1700 A core. Now, I was under the impression I would have access to the upper multipliers and none of them work. I Have even tried hard locking it at 13.5x and 14.0x to no avail. Now if I connect the last L3 bridge to unlock the lower multipilers, they all work up to 12.5x. Am I missing something here?
