Re: GeForce 4 MX440 showing as an MX 420?
From a couple of overclocker sites & forums.
280/366 (or 183, if it reports actual, rather than DDR clock)
275/365
So the overclock achievable is a little less than 10% on the RAM - not surprsing, since it's 6nS RAM which is right on it's 166 (333) clock rating - and no ramsinks, and about 10% on the core, passive heatsinked.
Maybe there might be a little more in the tank, if heroically cooled, but I wouldn't expect much.
Unless you're aiming for records for this particular card, I'd say take an easy overclock, and come inside of those figures, maybe 265 / 350, or don't bother - there isn't enough overclocking reserve to make much difference - unplayable frame rates would still be unplayable, and some of the tests show 0-2% gain from a 10% overclock, others show pretty well the full 10%.
