    Nvidia lists the core/mem speeds of the 8400M G, as found in the W7S and possibly others, as 400/600 but every program I've used to check it (nTune, RivaTuner, ATITool) is showing 400/400 under the high performance profile and 275/200 under the power saver profile. For you other W7S owners (or owners of other laptops that use the 8400M G), is this normal? I have yet to be able to create a situation where it runs at 400/600, which is mildly disturbing.

    I've also noted that Powermizer doesn't work, as in not dynamically changing the speeds based on load. This is despite me using the 163.16 drivers with modified INF (as found on laptopvideo2go.com) in 32-bit Vista. I have no idea why that would be the case.

    Under RivaTuner my clocks are 432/400MHz under 'high performance' and 300/200MHz under 'battery saving'. I'm not sure how nVidia states it as 400/600MHz - maybe it's a driver issue, maybe it's a confusion between GDDR2/3/4 speeds, maybe we need to overclock our cards to 'default factory settings'. I'm not sure to be honest as I'm looking for some answers as well.

    Yeah it's kinda odd. RivaTuner is showing it as 432/400 like you mentioned, whereas nTune shows it as 400/400, and ATITool is somehow borked and will only read as 400/400 regardless of which power profile I choose (which is obviously wrong).

    It's not a big concern to me since I only do light gaming on this laptop anyway (mostly WoW) and I have a fairly good desktop system for gaming. I just found it kind of weird for the difference in advertised and actual speed to be so big.
