--- Comment #13 from Rafał Miłecki <[email protected]> 2010-03-03 14:43:43 PST --- (In reply to comment #11) > I don't have all details memorized, but the maximum GPU clock for this chip is > 500MHz and the AC power state has both 500MHz and 330MHz CPU clocks. > The battery power state has 330MHz and 110MHz GPU clocks. It already shows driver uses at least 3 states. And you few lines earlier wrote: > But only state 1 and 2 are used by the Windows driver, > state 0 and 3 are never used. Anyway, I don't think it's really important to understand Windows driver. We may eventually need smarter reclocking algorithm.
