You can avoid this issue by undervolting your card. This can happen frequently to 1080TI FE in certain games. You haven't overclocked enough with the sliders.īlue: Voltage limited. You will notice one of these three colors: Go at the bottom of the second page of GPU-Z - Sensors tab -> PerfCap Reason. Goloith, a reader of my blog - where this article was originally posted - shared this info. GPU-Z tells you what’s holding back your overclock. Many manufacturers released an updated VBIOS to fix some of the overclocking issues with the Micron modules. Use GPU-Z to check which ones your card is using. Some cards have Micron modules that often have problems even with small 100-300 MHz overclocks. Most Pascal cards have Samsung memory modules that will easily overclock for 400-600+ MHz. Decrease it by 50 or 100 until you reach your last highest fps. The GPU probably won’t display artifact neither crash, but you will lose fps because the memory clock is unstable.ġ1. At a certain point the fps will stop rising and even drop: it is due to the memory error correction. Check the fps, it should be stable with slight variations of 1-3.ĩ. For example, even with a temperature of only 61 degree celsius, my card can’t go past 2,125 without displaying artifacts. Your temperature could greatly increase due to the overclock, and past a certain limit, the GPU Boost becomes unstable and reduces your maximum clock.Īnything after 2,000 - 2,100 MHz depends on luck. If it crashes or there are artifacts, reduce it by 25, until you are stable. If there are no artifacts or crashes, add 50 more and keep testing.Ħ. On MSI, add +50 to Core Clock and test Heaven for at least one minute. It gives your card more room to work with, and can’t cause any harm as long as your temperatures are safe.Ĥ. Open Heaven. You don’t need a MSI card to use it.ģ. Max the sliders of Power Limit and Temp Limit. 1. Download Unigine Heaven Benchmark - It's free.Ģ. Download MSI Afterburner.
