Thanks for all the helpful information I have read since I bought my 1070 recently. Plus Rep.
Is there usually only one week point?
So the use of XOC is to identify where the peaks and the dips are likely to be if I set up a manual curve in AB. Thats brilliant.
Every card in every motherboard seems to be different. On my motherboard, I can tune CPUPLL and VCCIO voltages and it can improve the performance. the XOC autotune test can be handy for seeing the effects of motherboard voltage adjustments as well.
My card, at default motherboard voltages on the z68 board I am using, dips over about 4 points, the worst one is around 1.0v. I can improve things by increasing my CPU PLL voltage slightly. I suspect that the dip may be the ceiling caused by the PCIe 2.0 bus that I am forced to use. Newer boards with PCIe 3.0 may be better but I have not tested my card in another board.
If it were me using the xoc autotune to profile my card, I would run the xoc test between 75 and 150 Mhz with 12.5mhz increments to start with. If it crashes straight away, drop the test to run 50 -125. If everything passes at +150, run the auto tune again but test between 150 and 200. I suggest breaking it down because the whole test takes a while to run and it gets boring waiting for it to finish all the tests. If the app crashes during the test, just restart it and it will pick up and start testing the next higher voltage point from where it crashed.
If you apply the curve that the auto tune creates to the card, you can save it to a profile in XOC if you want then shut down Precision XOC and start up afterburner. OPen the AB Curve windows and you will see the curve that XOC created displayed in the AB curve window so you can save it in an AB profile slot if you want. I personally would not expect that the XOC curve it creates is truely stable but it is a starting point. If it causes crashes, try dropping each point by 12 or 25 mhz and see if that is stable. If it is, you can try bumping individual points back up and test again.
