overclocking nook hd hummingbird

[majorwedgy]

Hi all not sure if I am unique but noticed other day when upgrading cm version that my antutu score dropped dramatically, went back through old score and realised my nook HD had been running at 1.5ghz tried a few of the cm11 versions and found all ran 1.3ghz except the 10 Jan version which automatically clocks the device at 1.5ghz and returns a score over 1000 points More than the others. Anyone else find this?
