Yes, I know, 1.45V maybe excessive for Maxwell....but why? This is the question cause temps never past 47℃...and temp target is 91℃!
Excessive maybe but not dangerous.
I will get a screen of this tonight and I will post here after.

Maxwell doesn't scale with voltage unless you are subzero cooling. More than likely you are hurting your performance by running that much voltage on water.

What exactly are you using to adjust the voltage? Cause.....unless you're running chilled water, you're not running 1.45v on regular water cooling and staying below 50c under load.

I'm using EVGA Precision X 16 for boosting clocks and Classified Controller for voltages. All under water EK blocks and double pump swiftech 1200L/h with 3 X radiators / 14cm. The biggest with 6 airflows .

It runs at 1.2112 according to the readout in Afterburner. I do have +30mV offset which, at one point, increased stability for the core overclock. The problem is when I remove the +30mV offset, the boost downclocks to 1479MHz from 1493MHz in the middle of the test. I think this is related to the way my boost fluctuates from 1404 and 1418MHz without an overclock (my core offset is +75).

Also, I have not had much luck using the classified voltage tuner to set static voltages (perhaps that's not how it works for maxwell, it seemed to work that way for my 780 classified). I don't have the time right now to dig into the BIOS editor and learn how to use it. It will have to wait until the weekends or later in August when I finish my summer grad school courses.

Yeah...there's something else happening there then. You're not running 1.45v with that setup, at those clocks, and staying under 50c. Send some screenshots of the GPUz sensors tab while under load, and the settings in AB / Classy voltage tool would be helpful.

Just measure it by hand with a meter man. My voltages had a crazy offset which I haven't seen on a graphics card yet. I would measure it with a meter and see what it reads with 1.21 input on the classified tool. Mine adds +.0200, so naturally I had to lower the voltage significantly, which helped with temps and stability.
