Why does GPU Boost kick in on games like MW3 that don't need a boost?

Phusius · May 19, 2012

I know my base clocks easily max out MW3... so why does GPU-Z always say the boost clocks not only kicked in it but OC'ed to what I have set in EVGA Precision... surely a game like that does not need a boost.

well check the nvidia control panel, maybe you can disable it for each application

Nvidia don't mind , and it helped them in benchmark comparisons againsst amd

Simply put it is down to how GPU boost is designed to work.

Essentially as long as there is TDP headroom the card will boost as far as possible, this will result in the best possible performance in any said game.

Unfortunately it has the side effect of boosting massively in games where the GPU goes under utilised (and thus has plenty of TDP headroom).

You can attempt to restrict this behaviour by reducing the power target from the 100% base it is set at in Afterburner (I assume you can do similar in precision). If you set it at say 75% (or -25% depending on how it is outputted) when you play COD it shouldn't boost very far (if at all).

I am ok with it boosting in every game as long as it is not going to wear out the life of my card, fyi, it never gets past 64 celsius 99% of the time with the fan profile I have set to curve quite high.

The fan noise isn't that bad honestly on this card, which is surprising.

Just limit your games with VSync. Your card will process only enough for 60fps or whatever your refresh rate is on your monitor.

I have read several websites people reporting same as you, on almost all games. I think Nvidia never got rid of the hot clocks, I think they just renamed it to BOOST, so that we think they got rid of it, coz it runs all the time just like the hot clocks on the older cards

GPU boost is nothing like the old shader hot clocks at all.
