Overclocking help 1070 FTW2

[Mark Kaine]

Ok so I can't get the auto overclock to work in precision x1, but I did some basic OC 

Memory +110

Core +40

Power limit +0 (no change) 

Temp limit +92 (max) 

 

I don't really want to up the power limit, from experience with my old 1060 it doesn't do much, and even then I'd rather down volt than put more voltage, also the game I'm playing traditionally hates too much voltage (Monster Hunter World) 

 

Anyways, so far so good, I get 200 points more in superposition, but when I'm playing a game the core clock goes from 2000 MHz to 1974 MHz for apparently no reason, temp is 60C max, power usage is around 65% so there should be plenty of overhead? 

 

For example superposition uses 75% and does not downclock (its probably just too short, but still it uses more power) 

 

So my question is what would I typically need to do for the card to not downclock from 2000 MHz? 

 

Seems odd to me because as said temps seem fine, power usage also

Up the power limit. What it does is it allows the card to hold its higher clocks longer before stepping down as heat/temps rise.

Power limit is EVERYTHING on Nvidia GPUs the last few years to properly hold your set clocks.

Voltage is more placebo as it depends on cooling and PWR first and only allows higher voltage if PWR and Cold are kept in check.

 

You could add a theoretical +195 to the core but the PWR limit at stock holds the core back anyway from reaching or holding it.

Ok I try that, so just set it to max I guess? 

 

The weird thing is the only thing that let my 1060 hold its clock was temp, as soon above 60C it would downclock 50 Hz or so,  power limit did not do much at all really, except crash my game lol (and only that, stuff like Firestrike etc didn't crash) 

 

But ok, thanks I'll give it a try anyway, and typically I should get higher memory clocks too I guess?

Unlike AMD, Nvidia hide junction/hotspot/internal temperature from end user. It probably reached a level that GPU Boost decide to stop boosting or even downclock.

Yea, slide it all the way right.

Ok I put the power limit to +112, the max, and plenty (my 1060 only went to 108) but it still downclocked after a few minutes to *1974*mhz from 2000mhz.

And you know what else? Temp was at *61*C...

 

I mean I understand power limit is what everyone says, but as I mentioned from my 1060 I know GTX 1000 series will throttle above ~59C... not much mind you but it will.

 

So I set the fans to 69% (to test) ran again. It did *not* downclock, stayed at 56C max... 

 

Kind of sucks tbh because 69% fan curve is quite loud on this card but for now it's my only 'solution' for this downclock problem. 

 

So yeah I set a custom fan curve that's 69% @  54C and will test that now.

 

 

I'm not saying you guys are wrong about the power limit but I can't say I understand why it's seemingly not working for me, all it does is make the card run hotter lol

Only increase power limit if you're hitting or almost hitting the power limit. From the OSD it show you're only using 50% of the total board power, no point raising the power limit.

Yeah, that's what I thought... 

 

Oof, I let superposition run twice... Getting the same problem it just takes longer... Downclocks to 1974, @ 58C, so I seem to have been wrong with the temp limit for throttling, it was like that on the 1060 tho.

 

Well the bright side is, 1974 is about the frequency I got with the 1060, 1963 to be precise, and it *never* down clocked and it also never exceeded 59C (while gaming) 

 

So maybe 1974 is just the limit for this card...? 

Not so bad but I had hoped it go above 2000mhz or something. 

 

Eh, well, currently set it to 90 power limit (so 10 less than default) ... No difference, except it goes to 1974 quicker, but I don't see how that matters, it's only at 2000 for a few minutes either way lol. 

 

Testing memory now, maybe I get better scores with that, also, I guess testing how low I can go with power limit, although 90 seems "fine" and I don't really know what im doing haha (regarding under volting) 

 

[Mark Kaine]

Ok I *knew* this...

Which in turns allows more overclocking headroom. Note that with the Pascal archetecture that the clock speeds will drop once the GPU core reaches 60 degrees Celsius.

From EVGA, but this is for all gtx 10 series, the problem is mine already starts down clocking at about 56 C... Ugh. 

 

So it's just a "not so great" card I guess... (still its not right, it shouldn't do that this early...) 

 

Lol and the other problem is I can't really get much higher than 2000mhz... Even with max power limit, my 1060 went to almost 2100 no problem (before it then downclocked to about 1963)

 

I guess that's just how it is? The 1070 is still whooping 11hz (?) faster lmao and obviously much more powerful anyway.

@SkilledRebuilds

 

Ok,ok I figured the 'issue' out : I really can't apply even +100 MHz, not even 75, 50 MHz is *max*

 

Voltage limit does nothing, I even tried the secondary BIOS that's supposed to be better for overclocking, same exact results, 50 MHz plus, anymore and it crashes in any benchmarks!

 

So I'm just wondering if I should return the card, seems really a lemon, and the fact the "overclocking BIOS" isn't any better is the kicker.
