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 ;)
 
New Microcode Bios with further degradation fix for Intel 13th and 14th Gen CPUs incoming:

Holy crap! And they told us 0x12B was the final fix for our Raptor Lake issues. Well, I guess we can see this as both a positive (i.e. that they're being forthcoming) and a negative (i.e. it might hurt the confidence level we can have in Intel). Let’s hope it’s a very isolated case.

As far as I have read, the 0x12F microcode improves what was previously done with the 0x12B microcode, which fixed the most important issue. Taking advantage of all these months, they have done tests on more computers and conditions, especially in those computers that are kept on all day and with few active processes (like mine). According to Intel, the impact of this microcode on performance is not even measurable, so it is understood that we will not see any change compared to 0x12B. We will see that when MSI releases the BIOS with the new microcode. I hope soon.
 
Isn't that literally exactly what they said last time? And then, does that mean the manual limit setting doesn't work? It would have to work, that setting is on MSI's end, isn't it?

update based on Intel’s investigation of a limited number of reports regarding systems continuously running for multiple days with low-activity and lightly-threaded workloads.

Most likely Intel is the one to blame for this. Motherboard manufacture can reduce the power/current limit to meet Intel recommended setting and it's already done a while ago. Basically it's trading the performance for stability. Now they mention about vmin shift, the solution should be included in microcode 0x12B already but guess that's not entirely true. More microcode is coming to address this. :cry:
 
FYI some more details here:
 
Today the new BIOS with Microcode 0x12F was released as a Beta (7D91vHH1).

Beta?
 
Okay, it definitely did change the bios settings. Still new to this stuff, obviously.

What's weird, it changed the boot process, I cannot get into the bios anymore. Not easily anyway. And half of the restarts it fails to handshake with my tv? Weird deal man. I assumed Bios flashback meant exactly that, that i can revert the bios update by loading an old one. Am I correct in that assumption?

But without even getting in there yet, it obviously reset everything. Which makes sense
 
Also, once I am able to get into the bios, I'm going to leave it like it is for a bit and just see; Will I be able to tell a difference between settings that score 42,000 and 37,000? I would not be the least bit surprised to discover that I cannot tell a difference. I guess we'll see
 
I always try to recommend that users take screenshots of ALL BIOS screens (including memory sub-timings) BEFORE updating the BIOS. If you have a second PC or Laptop that you can put next to the new BIOS screens, you can easily compare the before and after. Just last week, I was able to quickly spot four new settings, a few renamed settings, and a change in behavior of one setting that had a dependency to another setting - all after just one BIOS update. That’s in addition to the setting values getting reset, often including your custom fan profiles. I also make sure I know my AC/DC loadline values while in Windows in case their relationship to CPU Lite Load changes.

Basically. there’s a lot that can change from BIOS version to version and none of it is documented.

Yes indeed. I figured it would. So I put it all back and it still scored 37,000 area. This bios is garbage.

Not only that, but the vids are actually higher. Like 1.5. way higher than they were before. It runs cool, I'll give it that, but it's slow. I already went back to 12b? I think it was. Didn't have time to adjust any settings though. I'll do that later

Stay away from the beta bios. I've already went back to 12b, and it still will not take any of the settings I change in bios at all. It's at the default settings every time I get back in there. I'm guessing it's the management engine firmware? Not sure, I've tried to reinstall the same firmware from 12b, and it won't let me, does anybody know how to roll back the ME firmware?
