Decent 1080ti OC?

[AngelOfBodom]

Hey everyone. 

 

Finally have time to mess around with my PC (yay grad school....). Anyway, I wanted to know if this OC on my 1080ti is half decent. I know there is variation between cards due to individual factors, etc. Just want to see how much I can push this card and get the most out of it for as long as I can. Should I enable the voltage control? I remember reading that it didnt matter too much on pascal, but maybe that information is wrong. 

 

Additionally, any tips or resources to help with gpu overclocking would be helpful. I know the basics, but would love to read more into advanced stuff.

do enable voltage monitoring

Looks pretty good, you can definitely get a lot more than 100Mhz  on the memory probably closer to 400-600Mhz just depends, your best bet is to find the limits of your card.

OC the core as high as it will go without crashing leaving everything else stock. Run FurMark Stress Test for about 5 mins if you crash just keep backing it down till you no longer crash at 5 mins, then run a 30 min test. 

Once done do the same for your memory. 

 

This will give you the limits of your card and you can set your OC to what you fill comfortable with.

Just push all the voltage and power to max, it's limited anyway.

hell no not Furmark, it will just slam onto the power limit way too early to show the actual gaming frequency

some cards are so limited by the power limit that extra voltage gives less room for frequency, just saying since I dont know the actual card model

Uh, to keep higher frequencies stable you need to add voltage.

It's not one or the other.

Pascal is limited primarily due to power limits, adding voltage could end up lessening how high it can clock due to hitting the power ceiling. My 1070 ti is limited in that way, and I'd need to flash a new vbios with a higher power limit if I wanted to adjust voltage.

Pascal is not limited primarily by power limits.

It's almost always the silicon lottery.

This is why almost every 1080ti gets between 2000 and 2200MHz no matter how much power and cooling you throw at it.

You can have a 350W TDP card with a full cover waterblock on it and a custom loop and you will get the same overclock as an air cooled reference card.

If you remove the power limit or your card starts out with a very generous one that is. Many more restricted cards just lose frequency when you use their max voltage

[TheDankKoosh]

If you'd like to push your 1080 ti to the absolute max you'll need one of the high power limit vbios. I believe the amp extreme has the highest power limit, so here's a vbios dump

Explain how my 1070 ti hits a 2050 mhz ceiling, even though it's stable at higher clocks. I could easily hit 2125 on this with a higher power limit.

Explain how you know it's stable at higher clocks if it can't go above 2050??

1. He flashed a higher power limit bios

 

2. I myself used AC:Origins as the benchmark, letting the 1070 run default voltage (1.08v) will lead to a max 2025MHz. Manually using the voltage frequency curve I can push 1.03v and 2076MHz.

It can hit those clocks for a little while before heat power loss and gpu boost start to throttle it down, this is in furmark as well.

So then it's thermal throttling not power throttling...

Heat power loss..... At max fans it doesn't go above 60

Heat is a form of power loss, yes....

 

Are you talking about power throttling or thermal throttling?

Power throttling due to the heat climbing, the vrm and die become less efficient and consume enough extra power to make clocks go down.

If clocks go down then so does power consumption.

Also I don't think you know the difference between heat and temperature.

Only very slightly, there is a fine line of how clocks affect power consumption, where 50mhz will probably only make few watt difference.

I know the difference between heat and temperature, when my components heat up, they are running less efficiently, correct? That decrease in efficiency will bring my clocks down significantly due to power limit throttling, also, since I have 225w running through my card my vrm is also losing more to it's efficiency curve it affects me even more.

Is this furmark better than the MSI one? Also, why would one not consider Heaven(aside from pushing it top the absolute max)? I remember Jay and Kyle mention it for stability and such. 

I havent had too much time to test both the core and memory separate. I have looked at reviews and saved a profile with their numbers (kinda like an unrealistic goal or whatever), another with those numbers but halved, another from the afterburner auto oc too, and my own lightly tested variant off the msi numbers.

how much performance could doing this potentially get me? just like my other components, unfortunately.... i feel like i may just not have great luck with the silicon lottery. But then again, i probably wasnt doing enough testing. If I flash the bios, would it make a huge difference compared to unlocking the voltage and adjusting whatever comes stock on the card? 

 

again, just seems like a lot of differentiated views and my goal is just to get the most out of this 1440p 144hz panel. ><
