Strongest man in the world can't lift much while balancing on one leg, yet a kid with half his strength standing on two feet, will lift more than he can. You'll get more out of moderation across everything than pushing maximums in some things. With that in mind, maxing out power limits can be detrimental to performance because now power isn't as much a limited factor, which can stress other components, allow too much amperage or voltage use, create more heat, which raises resistances in inductors etc. So even if temps are good in the nemory, voltages might be high on the gpu or in the VRM's or you might have hit physical limits in the caps or inductors etc. The clocks will stop boosting up when some component reaches what the card considers its max tolerance. You'll see boosting upto a certain amount but that's governed by multiple things, not just temps in one area like memory, but also the gpu, the gpu voltages, VRM's, power limits, etc. The guides are a guide, a tool, not Gospel or Canon, and don't necessarily work the same on different cards.īoost clocks are an OC, by the factory, so there's no guarantee of any one particular speed. If they immediately drop, power limit isn't the issue, something else is holding the card and you aren't seeing maximum applicable Boost, which could be gpu temps, airflow, memory clocks, gpu voltage etc. If scores maintain, or go up, keep dropping power limit until you peak out and scores start dropping. I'd use TimeSpy to test the card, starting with max power limit, then start dropping it slowly and testing in between. Unfortunately, this will increase the idle heat and power draw of your GPU, even when you’re not doing anything. Setting max power limits increases voltages and amperage (ie Power) and often that will be detrimental to Gpu Boost as temps will throttle performance. Now, it’s tempting to hit up the driver’s global settings and set the power management mode to the aforementioned value and never think about it again. And that's not the only game that does that, but is a more extreme case. Even a 100% power limit set on the card shows averages closer to 107%-109%. If you OC your card to 107% power limit, then play Amazon's New World, you'll cook your card if it doesn't immediately throttle down as power limits will see North of 120%. They only apply to specific things, not a general use case.
