I think you will love it! I have my GTX 1080 Memory Clock at +400 in MSI Afterburner and am able to get a stable 2100 MHz GPU Clock when running the Unigine Heaven benchmark, and all that with low fan noise and very low temps. I can get the Memory Clock up to +800 before crashing, but don't find there is much performance benefit so have backed it off to +400.
I thought it might be helpful to show the settings and results via images, so I have some here. In MSI Afterburner 4.3.0 Beta 4 (
Download - Guru3D.com) the Voltage/Frequency curve editor can be activated with the
<Ctrl> +
<F> keyboard shortcut. What has worked for me is to find the stable Core Clock increase by using the typical slider method. Then using the editor, I choose a voltage that I want to run at when at full load by clicking the little square above the voltage in the graph and dragging it up to a frequency I want, which will be displayed on the left side of the graph. When I apply the changes the higher voltages are flatlined at that frequency. The GPU will then run at that frequency most of the time when under full load, but might come down 1 or 2 steps (13 MHz each) over time. I understand that 1093 mV is the highest currently allowed on the GTX 1080, so I chose a lower voltage of 1050 mV (shows as 1049 mV in Afterburner) and a frequency of 2113 MHz. When I use a higher voltage such as 1081 mV, I get the same performance in the Unigine Heaven benchmark, but the clock speed fluctuates a bit. When I use 1050 mV I get a straight line for the clock speed at 2113 MHz, and after a few minutes it lowers to 2100 MHz and stays there, so it seems that GPU Boost 3.0 is happier (can software be happy
) at that voltage on my card.
I came upon this idea by using the Scan Mode in EVGA Precision XOC (
http://www.evga.com/precisionxoc/). I noticed that the higher voltages were able to be increased much more than the ones below 1.050 Volt or so, but this might vary with each GPU. So I bumped up my chosen voltage to the point the driver crashed and then lowered it a bit. I tried different voltages but am happiest with the current setting. There is some good information at
GPU Boost 3.0: Finer-Grained Clockspeed Controls, and a video at
GPUBoost 3.0 and Overclocking with the GTX 1080.
