Well I got some news to finally post here again
My Maximus X Hero board now has a new BIOS update being offered, and I'll install it this weekend

   Information

Version 2603 Beta Version
2021/04/15 10.45 MBytes
ROG MAXIMUS X HERO BIOS 2603

"- Add Resizable BAR support for Nvidia RTX 30 series cards to potentially deliver more performance to gamers in select titles.

Before running the USB BIOS Flashback tool, please rename the BIOS file (M10H.CAP) using BIOSRenamer.

Please note that this is a beta BIOS version of the motherboard which is still undergoing final testing before its official release. The UEFI, its firmware and all content found on it are provided on an “as is” and “as available” basis. ASUS does not give any warranties, whether express or limited, as to the suitability, compatibility, or usability of the UEFI, its firmware or any of its content. Except as provided in the Product warranty and to the maximum extent permitted by law, ASUS is not responsible for direct, special, incidental or consequential damages resulting from using this beta BIOS."

If any one else do it too, make sure you still have a copy of your last BIOS, and your board has the BIOS Flashback® button

I just installed the new bios and was going to reset my overclock settings, but decided to run at default for awhile since the new bios is still beta. I don't notice any difference from my previous overclock (was only overclocked to 4.9) so wondering if I should bother overclocking again. Any advice? Thanks

I reset all my stuff up, specially brought the voltages down, as my cpu can run 5GHZ well using 1.2 volts with +0.170 offset, and I set VCCIO and VCCSA to 1.1v keeps the temps and fan rpms down.

Perfect thanks a lot. Will give it a try

You're welcome, just know that; my CPU is an 8 core 9900K and I totally won the silicone lottery, with a chip at least in the top 5% for over clocking and undervolting.
