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.

yeah re-run the benchmark with GameDVR disabled, graphic scores still around 20,8-20,9 K just a margin error

still didnt break 21K+ perfectly

i would want to test with custom curve

what is the lowest point voltage to be increased in custom curve? start from 0.950v or 1.025v?

Just a little clue from what i observed, In Graphic Test 2 you can guess the graphic scores from Framerates,

In the very end of Graphic test 2, if you hit +90FPS, your graphic scores will be likely to break 21k+rolleyes.gif

You can just run Graphic Test 1 & 2 only to observe the graphic scores behavior, you dont need to run full test every time.

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.

I would leave everything else as you have it to get 20900 and just try increasing the .950v point up to 2000 or 2025 and try that. If you use HWInfo. The voltage at .950 seems to be the one that controls the "video clock" result. I have no idea what the Video clock is actually supposed to do and the reported frequency does not seem to relate to anything on the curve, but I have found that I get my best performance If I can run that as high as possible. It may well be that it has an effect on the cards pstates but none of that information is reported in AB or HWinfo

 

As far as I have been able to work out, Nvidia actually uses different voltage points along the curve to adjust different settings for the different features of the GPU. Unfortunately, Nvidia don't bother telling us what they actually are.

 

I notices that If I get better than 118 at the end of Graphics test 1, I usually get a great score

3d mark firestrike result

+75 core clock, +600memory (9200mhz effective), max voltage, max power, 100% fanspeed.
highest point core clock is at 2076mhz seen in curve table. Custom curve = no.
Overall & Graphic scores pretty much the same as before,i didn't see any improvement.

Why reddit saying there is an improvement, https://www.reddit.com/r/nvidia/comments/63t2bg/driver_38165_faqdiscussion_thread/
AS you can see 381.65+w10 CU got +500points graphic scores on 3d mark firestrike compared with windows 10 AU (anniversary update old version). i didn't see any improvement on my system.

I OC'd my card last night wth only +50 core and +500 gpu core. I saw marginal improvement in Firestrike. I tried time spy for DX12 and found out DX12 doesn't like even a little OC ....lol

You can have both installed at the same time, just don't run them at the same time

980 didn't have the curve to edit. It is a new feature with pascal cards that lets you eek out the last bit of performance from your card.

With the slider, it might go unstable at say, +100 if you are only using the slider. The instability is because one of the voltage points is unstable at +100 and the slider moves the entire fixed shape curve up and down. The weakest point could be say, 1.025V, All the other points might be quite happy at +150.

With the slider only, you waste all the OC potential of that extra 50 points for all the rest of the points other than the 1.025V.

Using the curve allows you, once you have identified which point is the weak one, to increase all the others up to their +150 max potential while leaving the 1.025 point at +100. The auto OC thing in Precision helps you identify the weak points on the curve more easily than starting from scratch.

The last time I tried Precision XOC I started having some weird issues. Even now the precision forums has people complaining about issues that disappear when XOC is uninstalled. I may try it otherwise. But how do you get to the curve feature in MS AB?

I have 2 cards here. A MSI Gaming Z with Micron that runs 2114-2128Mhz core and 4404Mhz VRAM max stable on max volt and power limits in MSI AB. Runs incredibly cool (never hits 60c on my custom fan profile) and is very stable. Clocks don't vary at all and never hits power limit.

Now, I also have a Gigabyte G1 Gaming. It clocks better, has Samsung that will do like 4700-4800 MHz and the core looks like it's good for like, 2128+ only even on stock it bounces all over the power limit.. Core clocks are all over the place with the G1 and I can't get it to just stabilize at all..

Is there like, a BIOS or tweak or whatever I can do to get a better power limit on the G1? I mean, it's (much) louder and hotter than the Gaming Z but hey if it clocks better..

My performance dropped dramatically after updating to the new windows 10 creators.

Getting around 11500~ physics score in Firestrike 3dmark now. Below 16k overall score..

Did you update the Video Driver after the Win 10 update?

I updated to the latest driver a few days ago, so before updating to the new Win10.
