    Nope, I have not done that yet. It's just experimenting with Precision X1 like I showed in that last video I uploaded. No farting around with a "curve" nonsense.

    Edit: What I did not show in the video is applying an offset first. Say +120. That establishes the minimum overclocked boost clocks and moves the entire clock frequency line across the spectrum of the voltage/frequency table at once. (Otherwise, if you do not apply the offset first, the minimum boost clock is stock and it drops to that value when the power limit is reached.) After applying an offset, then go to the voltage dot for the maximum voltage the GPU allows (which by default is 1.093V for 2080 Ti) and raising that dot up to the max stable core frequency, then apply. I actually figured that out after uploading the video.

    2.7 C lower on average.

    So, the parts for the shunt mod should be here (hopefully) by this weekend. Pushed the GPU a bit harder and recorded video of the power draw for a before/after video. Below is a still shot from the video showing the maximum total system power draw prior to the shut mod. (3DMark 11 Test 1). Also got a new high score while doing the power draw test.

    I'm missing out on the ice cold weather. For the past 24 hours, it has been 1 to 6 degrees. Add the wind chill and it feels like -8 degrees. Unfortunately, I had to turn on the heater downstairs in my cold box. The good news is I have two new weapons coming tomorrow, with the NVLink arriving today.

    Nice set of books along with Kill-A-Watt! The gpu is begging for total forgiveness for not getting Shunt mod earlier from nvidia when it set its virtual foot inside your household.
    800W for a system! I can't even push 300W on my BGA doing that my electricity gets cut-off or tripped, so I don't push it. It kills the battery subsystem as well.

    I can hardly wait to see what those new weapons are. :vbbiggrin:

    Yes, life-changing books. :vbthumbsup:

    The CPU alone can pull over 1,000W in Cinebench or wPrime 1024M at 5.2GHz. Of the 800W shown, about 350-375W is the GPU. It will be interesting to see how much it will be after the shunt mod. It will not be possible to tell how many watts are being used from monitoring software like HWiNFO64 and GPU-Z after the mod. The shunt mod purposefully causes the power utilization to be grossly under-reported (less than half the actual power used is reported) and that is why the mod works. So, the Kill-A-Watt (or other external hardware device) will be the only way it can be measured.

    @Mr. Fox We got to get our hands on those vBIOS Jay has.

    Maybe you guys need to check TPU vBIOS db https://www.techpowerup.com/vgabios...X+2080+Ti&interface=&memType=&memSize=&since=
    If you're lucky you might get updated vBIOS. Or else check unverified uploads. GPUz uploads unknown vBIOS to their db automatically, if you find them it'll make your day.
