perhaps fuss132 can put up a poll maybe
Rev 3 (v7l) for me as well. Purchased in May 2012.
1350MHz works, but I don't really see the point in OC, as the power consumption increases significantly for the additional 150MHz. Personally, I don't need the additional speed if the drawback is less battery life.
So, here come my personal UV settings, where I got the device to be stable (set min/max limit to one frequency / under-volt /run stability test / if it crashes, adjust UV):
300MHz: 750mV (min limit)
150MHz: 750mV (min limit)
At 1350MHz I got some strange results, because it was stable in the Test @ 1275mV, but crashed in real-world. But I would attribute that more to the combination of OC+UV+hotplug governor - so I reverted to 1200MHz and am happy.
750mV at 150MHz and 300MHz result from the fact that you cannot UV to less than 750mV for any given frequency (well, you can type in a lower number in setCPU, but it won't have any effect).
Subsequently, at least for my device, under-clocking to 150MHz does not yield any improvement over 300MHz, as the voltage level can be set to match...I would assume that @ 150MHz voltage level could be as low as 650~675mV...
