G-Sync not working

Ha-Nocri · Dec 29, 2022

Just switched from AMD to nVidia after 10 years, EVGA 3090 FTW3 ultra. Still the same terrible control panel. There is no undervolting? Experience software is asking me to register? What do you use to OC? I already miss Adrenalin. Texture streaming issues in Spider-man, image overall seems blurrier and worst of all free-sync is not working, it is always @144Hz. G-sync is turned on in CP. MY monitor is free-sync with range 30-90 Hz. I use CRU to move the range from 57-144. It worked flawlessly on my RX 6800. But on the 3090 monitor flickers like mad when applying and I have to hard-reset the PC. But when I go to CRU after reset it say the range is still 57-144 MHz.

Any ideas?

no one misses the amcrap drivers. and gecrap experience is useless except for the people who can't type nvidia.com and download a new driver every month.

there are no overclocking options in the nvidia control panel, you must use a 3rd party application such as afterburner.
as for G-Sync, in the nvidia control panel under 3D Settings>Manage 3D Settings make sure that Monitor Technology is set to G-SYNC Compatible and hit Apply, then go to Display>Set up G-SYNC and tick the checkbox on the Enable settings for the selected display model and hit apply.

Afterburner is what you want or I believe EVGA has their own software, Precision, for OC and undervolting control.

As for GeForce Experience, I uninstalled it. Useless piece of crap that is.

Use Afterburner for overclocking.
Freesync doesnt really work on Nvidia if you use CRU, You need Premium Gsync supported monitor.
And if you want to screen record using the GPU youll need to have GeForce Experience installed and logged in.

Ok, got it to "work" but not really. It's flickering and all sorts of artifacts. Is there a known work-around or do I really need to buy a new monitor?

Also voltage control is disabled, cannot enter any number, Only thing I can do is lower power limit I guess (and do the curve optimizer thing)?

Subjective aesthetics aside, the NVIDIA control panel is reasonably full featured for driver and profiles adjustments and NVIDIA Profile Inspector will cover what it doesn't. Don't install GeForce Experience, even if you want screen recording; 3rd party solutions (e.g. OBS) are superior.

For overclocking/undervolting NVIDIA cards, use MSI Afterburner's curve editor (CTRL + F). This isn't quite as capable as MorePowerTool on AMD, but it gives much more control than just the AMD software is capable of. The curve editor is infinitely better than the kind of voltage control you're looking for; it controls the clock speed used for any given voltage delivered and you can freely adjust or cap clocks and voltage as desired in 15MHz and 6.25mV increments.

As for overriding the VRR range on your display, I have no idea if there is a workaround. It's quite possible that you'll need to narrow the range further, or use different monitor options than you were using previously.

For overclocking and undervolting you can use real software like MSI Afterburner+RTSS, you need it for proper monitoring and FPS locking anyway, Adrenalin is a gimmick.

As for Adaptive Sync, I have my 38UC99 overclocked to 85 Hz and range edited from 52-72 to 42-85 and it works fine. It may occasionally not kick in properly and this display needs Adaptive Sync to go above 60, so it results in frame skipping, but driver reset fixes that most of the time, sometimes reboot is needed.

1440p monitors with this bizarre 30-90 range are some very early implementations so I very highly doubt that it ever worked flawlessly without flickering, but if you are having these kinds of issues then maybe it is not a standard VESA Adaptive Sync implementation and works only on AMD? This is very rare but who knows, adaptive synchronization is fairly well standardized now but it was a complete wild west at the beginning. Did you try to research that for your particular monitor model? There must be other people that tried to get this monitor to work on Nvidia GPU

The monitor in question is ASUS MG279Q. I found a solution online, an older monitor driver needs to be installed and it works fine. But now card idles at 120 W and never lowers clocks.

Also, voltage control is disabled in MSI AfterBurner and EVGA software also, so not sure if no 3xxx card has that option, or something else is going on?

Did you put prefer maximum performance on the nvidia control panel? if so thats why it wont idle lower your card.

In the option tab in MSI Afterburner you check these:

Thats from my laptop but you will have to do the same for your card in order to unlock the voltage control , you may need to restart after applying these settings to work.

Forget AMD from now on , you may be annoyed because everything is different but you will never have to search for game fixes or buged drivers or wait for updates for a new game or incompatibility in a few ingame settings that are going to punish your performance way more than it should.

I owned an R9 290X and from the day one to the moment i sold it i suffered ! From the day i bought my first nvidia card which was the 980ti to today 2080 i never had a single issue , i just open any game and just plays as it should and thats emotional health.

I always had problems with nVidia, that is why I switched to AMD, till now. I love adrenaline software and never had problems with drivers. Just wanted to check the dark side now.

Yes, that turned on the voltage control, thanks... but I cannot put negative value. So I can only increase voltage.

Is there just no way to undervolt nVidia cards (at least 3xxx series)?

You don’t undervolt that way. Use the MSI Afterburner V/F curve as Blameless described and it will do exactly what you want.

If you reduce the power limit instead, you lose performance. If you do it through the V/F curve, you can increase performance while reducing power consumption and limiting the card to a lower voltage point.

Leave voltage control disabled; you can’t decrease it, and you don’t want to raise it, as higher voltage just pushes you closer to power-limited scenarios anyway.

V/F curve is the way to go. Do some googling on how to use the curve editor and you’ll find exactly what you want to do in a really neat way.

no. it's only needed if you find OBS to be too complicated. that crap is not needed for anything, it's crapware

Correct me if I'm wrong, but it just increases frequency at each voltage point, so it doesn't really reduce power consumption, it stays the same. And it's practically the same like adding +200 MHz (for example) overall, just a bit more sophisticated?!

So what I did was put Power Limit at 80% and increased core and memory clocks to basically get the same performance at ~70W less

it means it will require LESS VOLTAGE for the SAME CLOCK, that's how undervoltting works.. and it will reduce power consumption quite a bit

No. Power consumption lowers if you cap the voltage point at a lower one. My 3080TI for example, is capped at 1.013mv (water cooled) in less intensive applications and 0.906mv in heavy games like Metro Exodus. I do this so the card never throttles due to power (keeps me under 450watt) and also reduces heat. Two different profiles based on what I’m playing. While doing that, I raise the clock speeds a ton. At .906 at stock, you’d be down in the 1700-1800s in clock speed. My card can do 1935-1950 at that voltage.. so I gained performance at that lower voltage point, since I raised the clock speeds at that point. In games such as COD MW2, if I use .906mv, my card will barely push 300-325watts.

The point of the V/F curve is to maximize performance at each set voltage point, and to cap your voltage so that the card doesn’t use the stupidly high 1.030v+ points that require a ton of power.

Using the power limit slider is not how I would recommend doing an undervolt. It leaves performance on the table.

you could set the core clock to a million GHz, if the card is reaching its power limit it will not boost to your intended target clock.

Ha-Nocri · Dec 29, 2022

Ok, so I let it scan for 26 minutes and it created this:

Rectangle Slope Font Screenshot Parallel

It seems better power-consumption wise, but it still can go above 400W at times.
Is there anything that can be done except lowering power limit?

Click on any point you want to lock to and then press L. Yellow line will appear, it will lock to this particular VF point. Thats how you undervolt, lock to a specific point on the curve and then increase the clock until it is unstable.

acoustic · Dec 29, 2022

I would choose a voltage around 0.937v. Set it to 1965Mhz (should be stable there..) Take all of the voltage points after it and drop them below 1965Mhz. Hit apply, and all the points should be flat after 1965Mhz.

what you want to see, is a flat line on every point after 0.937v (or whatever voltage you choose).

Look up the shortcuts for the v/f curve menu and it’ll make it a little easier/faster to alter how you like.
