RTX 5090 Won't Clock Up (MSI Afterburner)

[Deadmano]

I have a custom curve set to top out at 2857MHz at 910mV (easy stable my card achieves) and I've noticed that every so often when I am switching profiles (I have a strict undervolt one, and this one) the card seemingly refuses to clock beyond a certain point, in this case 1410MHz. Thermals are fine and I can't seem to find a cause for it. I don't have any power management options enabled and NVCP is set to default (not performance mode).

The card should be ramping up, but only seems to increase memory clock, not core clock. Doesn't matter what software or game I run; it stays at that low value as its max, and resetting the values to default does nothing.

The only fix for me is to restart my entire PC, upon which I can select the custom profile and it works as expected. Is this a known RTX 5x issue, an MSI Afterburner issue, or something else?

Thanks in advance!

Which driver version are you using? 572.83 has the issue fixed, allegedly

[GeForce RTX 5080/5090] Graphics cards may not run at full speeds on system reboot when overclocked [5088034]

I'm on 572.70. Legend! I'll give that a try and see if that doesn't help.

Though the issue here is that after a clean boot, switching between profiles has a chance to cause the card to stop running at full speeds. Not sure if that is somehow related, but worth a shot at this point. If you have any other pointers I could try I'd be happy to give them a shot, because it is really frustrating having to restart each time I want to apply an OC profile now!

How often do you switch profiles? If switch profiles is what is causing the behavior, then just stick to one that you can live with for the time being.

5000 series is still very new. I would imagine maturation of drivers and software will fix such behavior.

I have a profile for demanding/VR games, and then one for everything else (capped at 1800MHz as they don't need any more).

Based on @3x0's comment I noticed the following from the Guru3D forums;

Seems the issue was indeed known and I had no idea they had a forum!

NVIDIA released 572.75 hotfix driver, which finally addressed previously documented bug with voltage control API. NvAPI_GPU_ClientVoltRailsSetControl is now working as intended on RTX 5000 series graphics cards. Now you can safely unlock and use voltage control slider in MSI Afterburner or any other previously affected third party tools (including NVIDIA's own NVIDIA App) without risking to see unexpected performance degradation due to erroneously limiting maximum core clock frequency.
