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 ;)

Hi All,

was a long time user of the Bios version 7D91vH8 without any issues, but with the latest news about intel and stability wanted to try out this version.
Im not sure if its related but since then i have an issue with the 5.1 audio output.
The center speaker sounds very metallic,
Tried many things , swapping cables, swapping cable speakers, all directs to my audio onboard

I found out that when i lower the volume of the center speaker to max 15 in windows the sounds is normal
will make an separate post for more feedback

so at this moment i set my level overall to max 15 for al levels now so the sound is "equal"

Hi, I haven't checked this yet. Only today I sat down at the computer because my son usually besieges it. I installed this latest HC2 beta bios today. After installation, I cleared the bios using the button on the motherboard. Reboot and the system actually asks you to choose management. I chose the third one, MSI, and set everything the same as before on 7D91 HB2. For now, I'm checking if everything works stably. At the moment, cinebench R24 has a score better by 700 points, i.e. 25344. I'll just check prime95 for another 5 minutes and then I'm done.

What specific modifications have you done in your BIOS? Have you noted an increse of temperature with the new settings?

Thank you very much for the notice of the new BIOS. Let's see how it performs.
Has anyone tried this new BIOS version yet? How are the CPU temperatures?

I am by no means an expert. Reading Citay's guide was a big help.
I have a i7-14700K with no signs of degradation at this point. Usual Cinebench r23 score of 35800-36000. I updated the BIOS to v.HD1(Beta) yesterday and did some testing. I set the CPU cooler option to Intel setting and ran Cinebench r23 with HWinfo to monitor sensors.
At room temp of 25C, the default CPU Lite Load value was 14. 10-minute Cinebench run produced 280 watts and CPU Package temp of 94C and 2 P-cores thermal throttling. Cinebench score was 332xx. Yikes! I continued testing, reducing the CPU Lite Load level down each test until reaching level 10, arriving at Cinebench score 342xx with 260 watts and temps at 88C. I disabled IA CEP support and IA CEP for 14th Gen, ran Cinebench again and the wattage and temps remained about the same with the score going to 348xx. I was pleased with the CPU temps and wattage, but the Cinebench score was about 1K points lower than with BIOS v.HB with CPU Cooler set to Water Cooling.
This morning, I tested with BIOS CPU Cooler MSI Performance setting defaults which included CPU Lite Load at level 10 with a room temp of 25C. Cinebench r23 revealed an elevated score but CPU Package temps at 92C with 280 watts. I continued testing, only lowering CPU Lite Load each time with the final setting at level 5. Cinebench score 358xx, 260 watts and 88-90C for CPU Package temps. I believe the 90C and 260 watts are simply spikes during the Cinebench run.
For the time being, I plan to use the BIOS CPU Cooler MSI Performance option with CPU Lite Load at level 5. I will continue testing but this is my initial observations. I expect the CPU temps to decrease as ambient (room) temps decreases with Fall approaching.
System specs in signature.
Hope this helps.

In every day use you do not use all cores so do we lose performance with a test on cinebench tested with 2 or 4 cores when lowering CPU lite load?

Interesting question that someone with more knowledge and experience can answer. You might test and see.
I was only testing to determine CPU temps, wattage, and performance to avoid potential CPU degradation. My final test in Cinebench r23 multicore with MSI default settings except CPU Lite Load at level 5 was 88C at 258 watts with a score of 35799. Core VID was 1.317. Ambient temp of 25C.
I plan on leaving the BIOS settings there unless there is an update to further address the problems that Intel is trying to fix.

If i use "MSI Unlimited Settings" is there then still a limit on the processor's voltage nog higer then 1.55V? Or do we need to use "Intel Default Settings" for that?

The latest 0x129 microcode patch will limit the processor's voltage to no higher than 1.55 V.

My understanding is, if the MSI Unlimited setting is used, the CPU is off the leash. I assumed it was the old "water cooled" option in the previous BIOS. I did not test that option since I have no intention to use it again. I was trying to compare the Intel Default and MSI Performance settings to see which worked best for my specific system. My testing revealed the two BIOS options I used held the Core VID below 1.40 using lower CPU Lite Load settings, if I remember correctly. Hopefully, someone will test the MSI unlimited option and provide us with more information.

I am running "MSI Unlimited Settings" at this moment:
- CPU cooler tuning = "MSI Unlimited Settings" (default was "Intel Default Settings" but my cinebench was lower with default settings)
- CPU lite load = 5 (default is 9 and changing to 4 is lowering your bench temps with 10°C while keeping the same score)

Running at 240W max and 1.284v on cinebench multicore with lite load on 5.

This appears to be a question many of us are now asking. I just posted this comment in relation to BuildZoid's recent testing on a Gigabyte motherboard with the 0x129 code. I find it hard to understand why the 1.55V limit would not be so hardwired into the microcode that it could not be disabled. I mean, if it's that important why would Intel extend their warranty two years and then let motherboard users deactivate it, either deliberately or accidentally? It's hopefully just a bug, like CiTay wonders. If not, I really have to question what the heck Intel is up to? The way the Gigabyte board implements 0x129, you either have no upper voltage protection...or you have what is essentially a B-class motherboard (or worse) where you get someone else's defaults rammed down your throat - even if they make your chip run hotter and slower. It's really a head-scratcher, in my opinion.

EDIT: Maybe there is some middle ground, where you active the Intel Defaults at the CPU Cooler setting level and then go tinkering. The trouble I have with this thinking is that how do you know if one or more of the settings that we normally tweak or a regular basis doesn't end up deactivating the 1.55V protection? I mean, without an oscilloscope or HWInfo getting lucky, how would you ever know? It's another reason why I'm struggling to understand what Intel wants us to do?

I would be pleased with those results. You might have a little more performance available at CPU Lite Load level 6 while keeping the wattage, voltage and temps in check???

Between CPU Lite Load 4,5,6,7,8,9,... there is no more performance. Under CLL 4 the system become unstable thats all.

There's another new BIOS update today "7D91vHD2".. anyone give it a go yet and see the differences between the two 0x129 updates? Hoping the newer one fixes the really bad intel default settings.

I’m away on holiday now, but I’d love someone to test this. The older 0x129 version absolutely messed with my VIDs, VCORE and temps. Like, there was something seriously off with that version. I was tempted to roll back to a previous version…

WHY DONT MSI (or intel for that matter) PUBLISH SPEC SHEETS AND NOTES?????
