![]() ![]() If you would rather have your graphics card operate at full 3D clock speeds when running a 3D application, you may set the option "Power management mode" in the NVIDIA Control Panel's "Manage 3D settings" to "Prefer maximum performance" from the default "Adaptive" setting. Throttling of the GPU clock speeds is similar to the changing of the CPU clock speeds based on CPU usage that users have been accustomed to for years in their PCs. With the changes in the new 280.19 display drivers, the GPU will now be able to react faster to any sudden changes in GPU usage which can be seen in more frequent increases in GPU clock speeds and faster decreases to a lower level GPU clock speed. NVIDIA display drivers before version 280.19 were slow to respond to GPU utilization changes and as a result would negatively affect GPU performance. 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.After updating the NVIDIA display driver to version 280.19 or higher, a user may notice changed to the GPU clock speed and voltage throttling compared to previous drivers. ![]() 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. Setting max power limits increases voltages and amperage (ie Power) and often that will be detrimental to Gpu Boost as temps will throttle performance. ![]() 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%. screen mode the benefit being that FRTC can reduce GPU power consumption. They only apply to specific things, not a general use case. Use Application Settings Provides the 3D application with full control over. ![]()
