I'm starting a new topic with the idea of posting here any information regarding the BIOS update for the Msi Mag Z790 Tomahawk wifi DDR5 version. You can also share information about the stability, benefits, and issues of the update here.

A new version of the Bios has been released
7D91vH9
2023-11-08
Description:
- Updated CPU uCode.
- Updated Secure Boot mechanism.
- Updated OC Auto rules.
- P-core Beyond 6GHz+ feature optimized with i9 CPU.
- Intel APO function optimized.
- ME Firmware ver: ME_16.

Good luck ;)

I installed this new BIOS 7D91vHE1(Beta version) today. The changes I made are shown in the attached photo. This is an old photo showing my changes from the previous BIOS 0x129. A quick test in Cinebench R23 gave a result of 35600 points. On the default Intel settings the result was slightly over 33,000 points. During the test everything was monitored by HWinfo. As you can see in the attached screenshot thermal throttling does not occur. Critical core temperature does not occur either and voltages are normal, not high. I am satisfied. My processor seems to be from a good pool and the cooling does its job (Endorfy Navis F360). Memory overclocked from 6400 to 7200. During the 5 minutes of the Prime95 test, the CPU temperature was 92 degrees, throttling did not occur, the voltages were normal.

Just today I wanted to make all the preparations to update the BIOS to the latest version, although I was not convinced that it was a beta version. Fortunately, today a new non-beta version has been released.

Would anyone be willing to test how the computer works with this new BIOS?

I installed the v.HE this morning, reconfigured the new BIOS to my usual settings. Cinebench r23 score-35794 with VCore-1.317 and Package power-277 watts per HWinfo. No thermal throttling, no WHEA errors. At the moment, my system is stable and running as expected.
System specs in signature.

Ditto. This stable version is essentially the beta from a few weeks ago. It’s even got the same September release date.

System is very stable.

Only issues I’m having right now is with the last two Nvidia drivers - getting some stuttering in games. Reverting fixes this though so probably an Nvidia problem.

New bios 7D91vHE (non beta) won't install for me. Currently on 7D91vHD MAG Z790 Tomahawk wifi, when selecting E7D91IMS.HE0 file in bios flash it says file is not from MSI and won't allow me to flash. Can anyone help me out?

EDIT: nevermind, it works when loading from a usb stick but didn't when I had it on C drive.

I've seen that before because the file I was trying to flash was not extracted 😅

Hello to you, I am sorry for all of us for what is happening to us with processors 13 and 14, so I changed to a 12th i912900k and I of course updated with the latest version of MAG motherboard bios Z790 TOMAHAWK max WIFI and I get a memory overclocking failed error message when I try to activate the xmp and run the ddr5 in 6000 is this normal in your opinion it comes from the processor which does not support xmp or it can come from a poorly configured bios option, I read that it was necessary to deactivate the secure boot to supposedly give authorization to the machine is overclocked, is this true in your opinion? thank you for your kind feedback.

Speeds (data rates) above 4800 are never guaranteed with 12th gen CPUs, although the 12900K should typically have more luck. Try setting XMP again, but before saving and exiting the BIOS, lower the speed by 200 (or the closest setting) and see if you can boot into Windows. If not, try lowering another 200. Repeat the process until you can get it to boot, i.e. 5800, 5600, 5400, 5200, etc.

Once you find a setting that allows the PC to boot into Windows, you will need to do some stability testing to confirm that the CPU’s memory controller is happy under all load conditions. The amount of stability testing you do will depend on how critical the data is on your PC if it became corrupted. If this is primarily a gaming PC then try running the Cinebench R23 and then play games and/or do some back-to-back test runs of 3DMark Time Spy and Fire Strike. If this is much more than just a gaming PC then you will want to run applications specifically designed to test memory.

If you need further assistance, please start your own thread.

Thank you very much for your response, I will apply your advice and update you as soon as possible on the results.
From your experience, do you have to deactivate the secure boot option to carry out these manipulations or is it not necessary?

A BIOS question for my Z790 Tomahawk WIFI MB. There is a way to disable in BIOS the requirement to reset the Windows 11 PIN after a BIOS update. Does anyone remember the steps? I seem to remember a video on how to change the BIOS setting that was posted on this forum, but I can't find the thread or the video.
Any advice is appreciated.

The ME_Firmware goes from 16.1.32.2473 to 16.1.35.2557, but I don't know what kind of update the microcode includes. Perhaps it adds some kind of compatibility to new memory or other devices. Although if this were the case, MSI would have detailed it.

I hope this update doesn't mess up my ethernet card. When I first got the motherboard, I had to get an external wi-fi card because the internal one didn't work well (you know the problems with the intel chipset). However, until now I had not tried the ethernet card. I knew that the ethernet problems were bigger than the wi-fi ones, but in my case I haven't had any. It will be luck or who knows what combination of factors has allowed the ethernet card not to fail me.

Installed the new bios on my end. No issues to report.

I did have to reset my MS pin though - I got in to my MS account with my password and then imposed my original login pin. Bit weird.

All working as expected though.

Edit: apparently the pin reset is normal procedure sometimes for bios updates. Occasionally it resets the TPM chip. Make sure you know your MS password before you do this or you might lock yourself out.

No problems with the update. The 3th unlimited "MSI Water Cooler" profile in the bios runs best. Higher score benchmark and runs cooler then the first profile.
