tested 3 raspberry Pi 2s from Element 14 and 1 from RS-comms with 8Gb Samsung Class 6 cards and I can get nothing over

1100
500
500
over_voltage=6


however if I change the SD card to a UHS Speed Class 1 I can push them to

1150
500
500
over_voltage=6

however I think I will go back to the class 6 card and 1100Mhz


* Point to note these have no heatsink or fan, maybe I can push them a little more with these items.
