AMD64 Nice and Cool

[zorrt]

Hey guys, as the summary says, will the nice and cool feature whatever its called function when overclocking? would it still drop down to 1ghz when idling or doin general browsin?

It will if you're using the default multiplier........

It COULD work, but it depends on your overclock and the way you overvolt. Lets assume you're running a New Castle 3500+ at stock (since this is the info I have readily available). Your P-states would be as follows (multi/voltage): 11x/1.5v (2.2GHz), 10/1.4 2.0GHz), 9/1.3 (1.8GHz) and 5/1.1 (1.0GHz). Now, let's assume you overclock your HTT to 250. Whenever cool and quiet tries to change your settings it will use the above. That means that if you raised your VID in the bios, when cool and quiet goes to its max multi it will go down to the default voltage, which would leave you with a loaded, undervolted, overclocked CPU (aka. Instant BSOD). This can happen at different PStates, not just at max, if your CPU cant handle the particular frequency at the voltage that is being fed into it. Using percentage voltages (+3.3%, etc) gets around the voltage limitation, though. I only use the AMD driver (basically AMD's official CnQ) whenever I do mild overclocks (as in less than 20% or so) with very-slight-to-no voltage hikes.

If you want to overclock a lot, then you could use RMclock or another similar utility testing all the "p-states" that you set in there manually, for complete stability.
