I do not have a 6xx series card but would it not be a plus just to turn off GPU boost all together like I can do with my CPU ?okay at 70 C its supposed to drop by 13mhz or so. well mine is dropping twice that at 70 C. it goes from 1253mhz to 1241mhz at 69 C then it goes to 1228mhz at 70 C. power target is not the problem as that is only about 110% and I have set to 145%.

if you are under load and you hit 70 then its supposed to drop 13mhz and if you hit 80 it will drop another 13mhz. that is how its supposed to work. now if you are not using a lot of the gpu then it can drop at any time and by random amounts but my issue here is that its dropping twice at 70 C even at 98-99% load and that is NOT what it is supposed to do.U can't do that
@Toyota there is no universal law regarding boost unfortunately,it is different on each card.What happens when ur card reaches around 75C?
I was mislead under the impression that the new nvidia GPUs were cool and quite running guess not hey.whats pissing me off more is that until today I could keep the fan at 65% at 65C and it would never go over 70 C. now I have to put the fan at 75% to keep it from going over 70 C. and this is the exact same part of Metro 2033 I have tested dozens of times and the temps i my room are no hotter than usual.
This Boost shenanigans makes me want to stick to my 5xx series or even jump ship back to Ati.

I keep my fan @ auto and it does a good job keeping it cool.What happens if u keep it @ auto?Does FTW have non reference cooler?whats pissing me off more is that until today I could keep the fan at 65% at 65C and it would never go over 70 C. now I have to put the fan at 75% to keep it from going over 70 C. and this is the exact same part of Metro 2033 I have tested dozens of times and the temps i my room are no hotter than usual.
if left on auto then it will go to mid to upper 70s in demanding games. the 670 ftw card uses the reference 680 cooler.I keep my fan @ auto and it does a good job keeping it cool.What happens if u keep it @ auto?Does FTW have non reference cooler?

nope. as long as the TDP and certain temps are not exceeded then it will run its highest boost under full load. it would make no sense to run full boost at light loads. once 70 C is reached then the first throttle takes place. again though if it was under light load then it would not even be needing to boost. like in Dead Space 2 with vsync on, it will down clock super low at times and hardly even runs at the base clock. my entire pc only uses 96-120 watts when playing Dead Space 2 on max settings at 1920x1080 with vsync on.I thought it was just the opposite, when the gpu wasn't fully loaded is when it boosted. Much like Intel's turbo. (I might be wrong, mind you?)
who are you referring too?I just wanted to chip in and say that it makes perfect sense that your secondary GPU was the culprit all along. When you saw your primary GPU at 50 - 70% usage; indicated that it had slowed itself down to match the speed of your (crippled) secondary GPU. Remember, percentages are not absolute figures.
Are you monitoring the speeds of your GPUs as well (memory / core / shader clocks)? May be the secondary GPU down-clocks itself? Even if it shows 99% usage, if it is running at half the speed, it is only giving half the performance.
I'm not too fond of boost myself.But mine always stay at max boost before reaching 75C.Toyota increase the default voltage a bit.My default was 0.987v and since i have increased that to 1 it is showing more consistent behavior.
why though? that is not going to allow you to clock any higher as it will still go to the voltage it needs to when loaded and still be capped at 1.175.U can,just select the profile "G" from GPU tweak.It sets the default voltage to 1
