To be honest, I don't belive in *any* device not being able to handle DSP 600 at all or DSP 600 @ 805 MPU. IT's just a matter of voltage. If disabling vdd1 and using sane voltage result in DSP 600 @ MPU 805 (or even lower, lol) working great, it mean that SR vdd1 calculates too low voltage for such MPU and DSP, yep?

From my subjective perspective, power saving *is* present, with properly functional (= no errors) vdd1 - and I'm think I'm quite prone to placebo effect (I was very skeptical about so-called power saving with SR before freemangordon recalculated them). But, this isn't any dramatic power saving, so I think it's better to take higher voltage reserve, and make it working reliably on majority of devices in any situation, instead of trying to achieve best power-saving.

BTW, isn't there any way of making this value configurable for power-power-powder user, that are sure their devices can take it without errors? Of course I mean SR calculation values. That would allow us to set quite high default ones, still allowing willing people to adjust them.
