MSI Afterburner keeps changing power limit to 93% instead of keeping 100% on a 4090

As the title says, got a strange problem since installing the 4090 suprim x, afterburner keeps setting power limit to 93% no matter what I do, I can change it to 100 and save it, once I restart its back to 93% again, tried uninstalling deleting all settings and re-installing latest version, any ideas? cheers...

Not sure why it would do that are you using all four Power cables on the adapter. all are connected correctly no lose plugs.

Hi there, the cables are connected fine using the adapter, I have had no problems with the card at all, ran many benchmarks.

OK so on the odd chace PSU is doing something strange on power up and GPU power self test may not be registering as full power is you PSU set to Single rail operation or Multi Rail

Seems that the new Nvidia have some power sensing setting built in to the GPU that if it not read enough power at boot it may lower power setting in After Burner.

Nvidia has been sorely lacking in informat on just what the GPU dose at Boot

Who doesn’t know it, the funny adapter from NVIDIA, with which you can merge four PCIe 6+2 pin cables to be able to run graphics cards with up to 600 watts? If you only connect three plugs…

Ah ok, I will continue to manually reset it to 100% for now until a fix or update sorts it out, thank you :)

my MSI Suprim X has a severe coil whine. isn't this a quality card?

You can try change the PSU with a different model, it could decrease or remove the coil whine.
But if you think the coil whine is too loud, you can try to RMA it.

But what about the 93% power limit?

It's a known problem. Even jayztwocents on one of his videos get this with asus card. Gotta wait it out, you're an early adopter for the new series.
Also I think that 93% could be the 450W of the card, though things should be calculated differently so that 100% means 450W.

This query was answered a day ago on Reddit in r/MSI_Gaming - Question:

Installed a 4090 suprim liquid x. Connected the adapter to 4 pcie cables. Afterburner is showing a set power limit of 93% (slider will allow up to 110%) Why is it not defaulting to 100%? Any fix for this?
Edit: Fixed. New vBios from MSI fixed the issue (below). Gaming mode now defaults to 100% of expected power limit.

"Hi there,
There was an issue with early GAMING VBIOS, which was fixed a couple of days ago. Please send your graphics card's serial number via PM and we'll send you the link for the new VBIOS.
We'll start distributing new VBIOS via MSI Center in the upcoming days as well.
Edit: New VBIOS is available for both air cooled and liquid cooled SUPRIM models.
Thanks!"

Well it is from MSI UK Support Moderator so why would we even know about it not like we're not mushrooms
Guess Reddit Moderators not have same restrictions we do when it comes to V-Bios

As the issue is widespread, MSI provided us with some vBIOS.
Please make sure you READ and UNDERSTAND the instructions. Each vBIOS is specific to a batch!
We also do not provide any warranty this will go smoothly, so flash is at your own risk. You've been warned.

Alternatively you can wait for the vBIOS update to become available through MSI software. That is guaranteed to work (and not void warranty if things go wrong).

Interesting let's hope no one is daft enough to try and cross flash and brick there GPU
But we knows they will try if and blame MSI
