Question Afterburner makes me mad

[BarderoJ]

I set my curve - 2040mhz 1000mv, 2070 1025mv. At the start it works fine, but then afterburner can change that curve, for no reason. It can increase or decrease, so 2040 can become 2025 or 2055, 2070 can become 2055, 2085 or even 2100 or 2115. And this increase in frequencies cause crashes, then afterburner doesnt apply my curve - i choose saved pofile 2070 on 1025mv and afterburner applies 2085 or if i manually try to set 2085 to 2070 afterburner just shifts whole curve

F.e played re2r was alright, closed re2r launched cb2077, afterburner switched frequency to 2100 on 1025mv, and game crashes

** afterburner is latest verison.
gamerock rtx 3070ti, latest driver

What are your full PC specs ? Try doing a CLEAN reinstall and update of MSI AB tool and the GPU drivers. First remove all previous saved fan curve/power profiles in MSI AB, and then do a complete reinstall from scratch.

I don't know the specifics, but if I were to guess, I don't think MSI Afterburner is mucking with the V-F curve for craps and laughs, it's adjusting it to what it knows about the GPU it's working with.

In this case though, I'd set the curve a smidge lower. Any performance difference you'll only see in benchmarking apps.

I did a curve that works for my gpu in every possible scenario, i did count gpu boost there - thats why i run 2070mhz on 1025mv, cuz at 2100mhz i get a crash. So if afterburner didnt <Mod Edit> with my curve i'd not get any problem

gamerock 3070ti. Bios is modded(from gamerock 3070ti oc)
5600 oc via project hydra (4.925 all cores, but usually sits 4.8-4.85 cuz my cooler cant handle)
tuf b550m-plus (latest bios)
16gb ddr4 3200 cl16 kingston fury
850w psu

I did reinstall afterburner and it did nothing, it wasnt a "clean" reinstall tho. I also switched low lever hardware access from user to kerner, dunno if it helps

I did some experimentation with my V-F curve and it's likely that what you can edit doesn't line up with what the GPU actually supports. And it seems like, at least for my GPU, it only works with in 15MHz steps, which it'll round somewhere to the nearest 15MHz step. Don't know why Afterburner is designed like this.

In any case, you're going to have to slightly lower your V-F curve.

Wdm by "cant support". curve works perfectly fine, i did check it multiple times, also tested in 3dmark timespy for 2h. I get problems after afterburner messes with my curve

Okay so look at the first post again, you're saying that Afterburner is automatically adjusting the curve. I haven't seen this behavior in my 2-3 years of using MSI Afterburner and the only thing I can pull up is from this Reddit post which suggests temperature changes the curve automatically.

But even then, I don't see any change in the V-F curve on my end even when running under the default settings.

Like, curve can work fine for hour, two, maybe a day, nothing changes in afterburner. Temps are fine i hardly ever get above 73c, and how would temps change curve? if temps are high frequency goes down. Then afterburner messes with my curve, f.e adjusting my 2070mhz 1025mv to 2085mhz 1025mv (gpu boost comes in, i get 2100mhz and game crashes)
