While the guide is great and I have now a few profiles with really nice curves, does anyone have more technical information regarding how the OC Curve works?
Like, I note that when you initially setup a curve, the points/dots will spread a few voltage steps on the same clock close to your "target" one. For example, if I have my max (1093) at 2190 clock, the 4 or 5 dots before it will be at 2175.
But during tests I noted this would sometimes result on the next step down (2160) to be using low voltage because of this, so in some cases I edited all my last clocks to have like only 2 or 3 voltage steps.
But even that doesn't always works. Does anyone know how the interaction o voltage steps <-> clock should work?
Also, something not entirely clear to me yet: how boost (in this case 4.0 as I'm on series 20) is suppose to interact with curve OC?
In the majority of my curves I setup them while on idle (35C in my case) so my max/target clock is actually a little higher to what I want, as temperatures will rise and reduce the clock. For example my most stable curve so far is targeted at 2205, which will translate on a real clock of 2175Mhz during benchmarks/games.
But ONE of my curves (that I tweaked WHILE benchmark, so temps were at 55) is saved at 2175Mhz on max clock, but when I apply it while idle, it will overclock to 2220Mhz.
Is this curve bugged? How is the interaction suppose to be?
Thanks

You are hitting voltage and thermal walls. 1093 is not a magic number. My 2080ti's sweet spot is 1072. I stress my card with Adia64 and run video only to find the voltage sweet spot. I also stress the card when setting the voltage curve. This will help with keeping things locked during benching. Also use a good app to monitor voltages and thermals. I like SIV64 works great and is very accurate. Good luck.

Not sure you understood my questions and I found some stuff you said confusing. - We will always hit "voltage wall" using this method, that's why is called "how to force max voltage". - 1093 is the max allowed voltage on Turing chip, so they all should accept it provided you have a stable chip and proper cooling - Boost 4.0 downlock steps are not the same as thermal wall, if you were referring to it. Thermal wall is 88C on this chip. Of course on air is better to lock the voltage a bit lower if the stock cooler can't handle 1093mV and is thermal throttling badly, stable clock is better than have lots of fluctuations even if peaks higher. But thermal wall is not my case. Yes boost 4.0 will downclock a few steps and I'm compensating it with curve tweaks, but 55C on benchmarks is not even close to thermal wall. My curiosity is more about understanding how the voltage curve is suppose to interact with Boost algorithms and how to proper tweak the voltage <->clock multiple dots properly to get the most of it, as so far I have mixed curve behaviors as explained above. Like, why the curve sets same clock on multiple voltages? Is that how SHOULD be? Can tweak it give better results? Should be only ONE clock dot on the voltage you want? 2? 3? This kind of stuff =)

I understand everything you are asking using wall was probably the wrong term. The card will step down in thermal increments like 20c, 40c and 60c. So if you have the card pegged at 1093 and your card likes 1072 it will step down sooner. remember voltage creates heat and heat will cause the card to step down. Try to stress the card while you set the voltage curve and it should give you a sold lock.

So you are saying is best to setup the OC curve while stressing the card / max temps (which is what I did on that specific profile I mentioned)? Interesting, will see how it goes and what results I get.

I had the same problem as you are having. If you stress the card while monitoring your curve you can see it boost. I like Adia64 because it's windowed so you can see afterburner and siv64 all at the same time. Now you can see what the voltage and temps are doing while stressing the card. With that info you can see where the curve peeks and flattens out to establish your sweet spot. When you just use 1093 some of the cards don't like that voltage lock and the dots will decrease trying to lower your lock when you are stressing the card like benching. I also hit apply after each dot I set to -1 from the natural curve. Once you get this dialed in it works great!

I don't use Aida as it's GPU Stress test doesn't really heat up my card, it doesn't even get to 50C and TDP never goes above 80. So I used Heaven Benchmark instead, as the free version allows windowed mode and keeps running even focusing MSI AB/Curve editor above it. I tested some curve tweaks while stressing the card and it was interesting to discover some stuff (at least on my card) - setting 1093mV will always trigger VRel on perfCap. - sometimes VRel will also be 100% uptime depending on which clock the next dot after your max-target is. Ex: at some point I was lock at 2160Mhz on 1081mV @ 55C and VRel was 100% uptime. And no matter what, even dragging the curve down to 2130 VRel was still up, only going really low it stopped. It didn't made any sense to me so I went back and had the idea to changed the 1087mv dot to 2175, and just like that perfCap went idle. Not sure why and I didn't managed to get this work 100% of the time tough. So far I was able to do 2160Mhz on 1068mV at 55C, and even bumped the memory a bit more to to 8275Mhz. But there's a catch doing this way: my card idles at 35C, so when I apply this curve before starting a benchmark, it will boost to 2190 at 1068mV, which is too much of course and some benchmarks will crash right away. I wish we could just disable boost because right now is just not being helpful at all. I'll keep doing more tests.

Well I think I'm done with testings and tweaks, ended up with 3 profiles.
1)
Core clock: 2160Mhz while under 54C and 2145Mhz on benchmarks once hits 55C.
Memory: 8250MhzThis is the one Time Spy will run, so I consider the one to use with "sensitive" engines.
It's pretty solid, will dip below 2145Mhz on TS only for some seconds on the really heavy parts where TS max TDP.
2)
Core clock: 2175Mhz while under 54C, 2160Mhz if above.
Memory: 8250Mhz
So far tested The Division 2 with it and didn't crashed after a long session, 50C max temp so 2175Mhz stable.
I consider this the "default" one as this game has a sensitive engine.
Time Spy do not run on this thought, will crash mid run.
3)
Core clock: 2190Mhz under 54C, 2175Mhz above.
Memory: 8286Mhz
Superposition 1.1 will run on this, but I suspect sensitive games wont sustain long runs.
Probably the one at the verge of stability as I see some occasional flashes on superposition run, but no crash.
All profiles at 1087mV.
50C for gaming max, 56 for benchs
No perfCap, only occasional Power on TimeSpy run.

At the end of the day Afterburner's voltage curve is cool, but essentially quite useless unless there's a way to stop Nvidia Boost 3.0/4.0 from doing what it likes.
You can spend hours moving those little dots and save what you think is the perfect voltage curve, but next time you start the curve will not look anything like what you spent hours setting up.
The curve will look the same when you press the profile you saved it to in Afterburner, but when you hit that 'apply' button, all bets are off.
It doesn't matter whether you set the curve under idle temps or full load temps, Nvidia Boost will do what it likes!
If you set the curve at idle temps, then Boost will push your clock way higher than you supposedly set in your voltage curve max clock speed, and this can cause instability in gaming.
If you set the curve at full load temps, it will mess with things once again, and you will end up with a lower clock speed.
Save yourself a bunch of time and stick to the sliders.
Start with resetting everything in Afterburner and run Aida64 or whatever GPU stress test you like - for me Realbench is the most realistic in terms of replicating actual gaming loads across the entire system.
See what your GPU does running at stock, as that will give you a good idea what it 'likes'.
Lower your fan speed in Afterburner so that you can hover around the 65C mark, which for Pascal seems to be about the highest it will go assuming you have good cooling.
Then increase your clock/memory until you find it stable and save to a profile.
Then max your fan speed using the fan curve in Afterburner.
There will be many who will say the voltage curve somehow magically creates more stable overclocks, but unless you have a custom BIOS with power limits removed and higher voltages allowed, it's really a waste of time. I expect to be flamed, but I challenge anyone to prove that Afterburner's voltage curve can be locked and static to what a user set on a stock Nvidia FW, and it never changed or was ignored by Nvidia Boost.
I've spent countless hours across Pascal and Turing cards and Nvidia's Boost 3.0/4.0 has a mind of it's own.

@fleptronic I see on your sig that you have 2175/8250 with your kraken. Mind if I ask you your +core clock and voltage you have. I too have the same kraken setup, only thing is I have the 2080 XC Black Edition.

Hi I don't use +core, I use curve mode following this guide. Giving you my curve wont help, it's something you need to find out on your card. I use 1.087mv when OC is enabled.

Thx for the response, I really didn`t need the curve because I know it`s kinda a hit and miss thing. I was curious as to what was the voltage you had. Since we both have the same kraken setup

I don't consider using curve a hit or miss. For me it was really hard to master and find the correct spot, but when you do it, it will absolutely give you more overclock than using +core. Of course is only worth for crazy ones that must squeeze the absolute max out of the cards

Yeah I`ve been playing with this for quite a while and finding that sweet spot is a task. With the 1.087v do you go over 55c in temps

Upgraded to a 2080Ti FTW3 Ultra Hybrid and I can't seem to get it past 2100 mhz even at 1087/1093 mV. If I go up a step to 2115 MHz it'll instantly crash out of any game.
Might just be my card isn't the best for overclocking. I'm currently keeping it locked to 1087 mV @ 2070 MHz so I don't get VRel Perfcap. Any suggestions/advice? It'll step down to 2040 MHz @ 1087 mV as it approaches 55C.

Maybe your Overclocking of your CPU and Motherboard Memory is not stable with the RTX Graphics Card. I would set them back to Auto on both and make sure you have Reset the Bios after you installed your RTX Graphics Card and that the Motherboard Bios is updated. Make sure you are using 2 Separate PCIe Power Cables from the Power Supply to the Graphics Card. Your Power Supply maybe to small and even to old as well.

Remove any CPU, MB & RAM OC and test card How are you "loading the GPU" to check for Max MHz ? Keep the card Cool as possible - Is the Radiator being used as intake ? (FYI: max voltage can work against this) Room temp ? Sounds like the silicon lottery

Could be but I stressed my RAM/CPU with P95 small FFT test for 8 hours and didn't get any errors. I've got a 9700k 5 Ghz 1.3V and my RAM is 16 GB @ 3600 CL 15.

Radiator is being used as exhaust in a NZXT H400i case with push/pull ML120 Pro fans. Right now I'm just loading it with FFXIV under max settings. I might try putting it under load with Time Spy. Can't really use it as intake as I have a Kraken x62 for the CPU as intake on the front. I'll try removing the OC on my RAM/CPU and see what I can do. This card was also an RMA card because first one had horrible whine coming from the pump. This one wasn't much better I ended up doing the magnet trick to get rid of the whine. Edit: Oh and room temp is 21C.

P95 never tests the Memory to GPU so it would not hurt to test your RTX Card with then Set Auto to see if you get any better GPU Performance. Are you running X8 or X16 on the Graphics Card and in GEN3 Mode? You could run 3DMarks PCI Express Feature Test to see how the Bandwidth is on your PCIe Slot. You would need to keep the GPU Temperatures below 40°C to go any higher.

Set both back to auto and it still crashed. Using 2 PCIe power cables. PSU is a 850w Corsair RMX PSU Gold Certified. Bios are updated. bcavnaugh

Ran the PCI Express test and got these results PCIe x16 3.0 12.73 Gb/s Reset my CPU/RAM OC and only OC'd the GPU Core not the memory. This was also at 2145 MHz surprised it didn't crash running the test. Feel like I just lost the silicon lottery here, not sure.

Yep then it looks to be more about silicon lottery on your card. What I mean about the Memory is that Prime95 never touches the GPU Memory and MB Memory and it seems that the RTX Cards under normal OC of the MB Memory are not as stable as the Memory under a GTX Graphics Card. I have two of them and one 2040MHz and the other 2160MHz-2200MHz

Thanks for the help. Sucks because the original card I RMA'd OC'd to 2145MHz without crashing. Should have just kept it and done the magnet trick. Oh well not a huge performance loss either way.

If you don't use MSI Afterburner and use PX1 are you seeing the same low MHz?
