i'd say almost definitely not enough volts. Mine did the same altho not as low as that. 1.4v is the default and for my 3200 (Win) I found that 1.4v was fine from 2.0GHz all the way up to around 2.4GHz. After that 1.5v was needed but even 1.54v is still fine really. Only 10% after all and temps are not an issue with these new cores. Hope that helps!
