You're missing the point. There isn't some resistor on reference models that caps it at 300w, it has to be a bios/registry entry limitation based in how the non-ref cards have a 2 bios, one standard with ocp/lower limits and one unlocked. If we hack the locked bios or use something like racerx on it, it works in the same way as a reference card would.
With tsm106 example, unless he was already getting throttled by the limit, then of course his testings will show no change in wattage used. Just because you raise the limit doesn't actually mean you will use it.
Its evident there is some use merely my observing GHz users boosting graphs. Now, remember when the GHz came out, amd explained a new tdp calculation they used to determine the boosting state of the card. If I had to guess, these power limit % changes are directly affecting the outcome of these calculations and allowing a more lax boosting effect.Edited by jomama22 - 5/30/13 at 7:35am
