HWinfo64 is a good tool to monitor everything in your PC. you can also set it to include extra monitoring values in the Afterburner OSD
All cards/pcs behave differently so you have to experiment to find what is right for your rig. The only way you will get the right answer is to experiment
Try reduce the slider from +50 to +25 and then adjust the curve the at 1.093 the way you have here. If that doesnt work leave slider at 0 and adjust curve. Try the same thing and adjust curve to 2088 or 2075 and see if that is stable
You can also try leaving the voltage slider at 0 and adjusting the 1.063v point instead of 1.093v or adjust the voltage to about 30 and try adjusting the 1.075V point
I have also found the using the curve method gets a benefit for me if I increase the .975v point on the curve to 1999-2025 as well as increasing the 1.093/1.063v point
Firestrike loves memory overclock, Timespy not as much. +500 memory OC is good +600 really good, +700 Great, +800 fantastic
Motherboard settings can also have an effect. If you are getting BSOD, either 0x124 WHEA or Watchdog Timeout, the VCore (CPU Voltage) probably needs a slight increase or the load line calibration may need adjustment to stop voltage droop.
Also look at the VRM frequency and Phase control settings. Best to get specific advice on your board from an OC guide as I dont know your motherboard. I cannot give you good advice on the exact settings. When I first got my 1070, my VRM settings were set to extreme, turning them down to the optimized setting and even trying VRM spread spectum mode (Not CPU Spread Spectrum) helped with stability.
If you have VCCIO and or System Agent (VCCSA) voltages at auto, you may find improvements if you try and adjust them a little above the default settings. dont make big adjustments. one small step at a time and test
Ok, I could reach 2113mhz on 1093 (I had the slider on 55 and I could reduce it to 50 and increase 1093 voltage to 2113mhz), on 2126 crash so that's the limit for that voltage. What now? Should I test the others voltages individualy? I see some improvements but looks like I'm reaching the limit, I have more benefits ocing the memory than core (this is normall, the memory is complete stable at +770 (9548mhz))
Something that I've seen is that the frecuency in 1093 is not 2113mhz but sometimes 2088, 2101, I guess that fluctuation is normal.
The CPU is an i7 7700k default, the only change that I did to the motherboard (Maximus IX Formula) is to increase the RAM frecuency and latency to its default (3200 CL14) that's all. I'm not getting any BSOD, the test that I'm making is on Heaven and 3D Mark (Fire Strike, Fire Strike Ultra, Game Spy...) and they just crash or simply draw some artifacts.
I keep going testing.
There is no such thing as an absolute answer. every computer is different. try them all.
3d mark does love memory overclocks. +770 is very good. you may want to install OCCT and run the GPU test with error checking. The memory does have some error correction but at those speeds it is possible that errors are outweighing the performance improvements. I know some guys can run +800 memory but they actually get better performance at +600 due to errors. The errors can also be the reason for intermittent failure during benchmarks that you can't identify any other reason for.
I do not have any direct experience with Z270 so these suggestions are a bit generic but may inspire you.
Make sure that any CPU and memory overclocks are stable because these will have an effect in GPU @ 2100mhz benchmark runs as well. Asus boards do overclock the CPU by default setting all core turbo multiplier. XMP can also change BCLK. Not sure about z270 but that generally overclocks the PCIe bus that can cause instability. These pascal cards put a lot more stress on the PCIe bus than even a maxwell card so they will show up areas that are slightly out of tune more easily as well
The motherboard settings can be off enough to not BSOD but under the heavy graphics load be enough for the graphics or a DX driver to crash. A small increase in VCCIO or VCCSA voltage with a high speed memory installation like yours may help in stability. Also pay attention to the VRM and load line calibration settings. Turning things up to extreme doesnt always mean better. and having a large difference between vcore and CPU VID, while it still runs, can impact performance of the GPU

I am running on z68 with an i7-2600. When I first got my card July last year, I got one of the first Micron cards on the market and that came with the bonus Micron memory controller bug. The max I could do was a +400 memory oc before it crash. best I could do was about 14300 firestrike with 20200 graphics and about 9500 physics. After I managed to get Nvidia to produce the Bug fix bios and a whole lot of motherboard setting tweaks, I can now get 15200 firestrike with 21000 graphics and 10500 Physics which is on par with an i5-6600 so whatever you do, don't just write everything off to "silicon lottery".
