Quick clarification of Power limit %

[Toxicable]

For over clocking GPUs in afterburner the %power limit is the same as increasing the voltage when OCing a CPU right?

Kinda, its just increasing the maximum amount of power that the GPU can use, its not setting the voltage to a fixed amount.

[Peter Vaughan Truslow]

GPUs have a certain TDP that they normally refuse to go over, because the coolers are only guaranteed to handle that amount of dissapation.

increasing the power limit is giving the card permission to go above the TDP (thermal design power). sometimes it can do nothing, but sometimes your card will limit itself when overclocking to keep it within this limit, and increasing the limit may help.

if you are overclocking, crank the power limit slider to the max first.

if you play a game and then come out of it and look at afterburner and see the power tab is all the way up at 100 (looks like the images i posted) then up the power limit if its no where near it then your all fine
