BIOS 3901

I haven't tried the 3901 beta yet, because 3802 didn't work for me on Z690/12th Gen, the first ever BIOS that left me with blank screens and slow boots. So I have some questions:

1. Can it definitely be rolled back? 2. Is it even supposed to work with 12th Gen?

I believe that the recent microcode updates are really for 13th & 14th Gen, but there is no guidance in the BIOS release notes for 12th Gen users. At the end of the day, Z690 (and hence any BIOS release) is supposed to support 12th, 13th and 14th Gen right?

Have any 12th Gen users tried it yet on Z690? I have a lot of work on right now and if it doesn't work and can't be rolled back, then I'm in trouble. Thanks.

I have an Asus Z690 Apex with a 13900k processor.  On the MB I have 32 Gb of DDR5 ram and a 4090 GPU.  I flashed my bios with the newer 3901 update and didn’t even notice it was a beta.  Never seen Asus release Beta like this before.  I have 4 M.2 SSD with 4TB of room on each.  After flashing my MB all but one of my SSD showed up in the bios so I rolled back to 3802(probably have the number wrong but it’s the previous one) and now two out of 4 of the SSD’s show up.  3901 microcode can’t be reversed sadly so now I am stuck not being able to use two of my SSD until Asus releases an update.  

Unless I'm mistaken, I think the microcode is included with the BIOS, so it should roll back also. It's the ME firmware that cannot be rolled back, so maybe that got updated? I'm on a later ME firmware from MoKiChU anyway and that works fine with 3701. I still haven't tried 3901, waiting for it to come out of beta, but I had no luck at all with 3802. Maybe you can try 3701, that has been working great for me. 

Remember that it's probably best to have the latest microcode on 13th Gen though, technically I shouldn't need it on 12th Gen, so 3701 is Ok for me. Would be interesting to see if it helps with your SSD issues, but I'd be surprised if that's really a BIOS issue.  

Does you issue occur after a restart, a shutdown or all of the time?

Hi, despite all scepticism I'm on Bios 3902 Beta meanwhile. 13700K, Z690-I. 

Besides: Core VID is now 1.493 V max, before about 1.36 V max. Vcore 1.447 V max, before  rarely above 1.4 V max.  

PL1=PL2=125W 

All other settings BIOS default.

Shouldn't the Intel BIOS Updates prevent higher voltages? 

 

 

I'm not sure what's normal for your CPU, all I can tell you is that my 12900K has a max voltage of roughly 1.34V. The average is more like 1.27V and the minimum is approx. 0.74V. I haven't studied the voltage behaviour expected for 13th and 14th Gen CPUs, but as far as I know, you're better off running microcode 0x12B. Hopefully somebody else with your CPU can confirm what's expected and normal. 

This voltages above are with 3701 just doing Windows activities, not running games. I'm still waiting for 3901 to come out of Beta. I'm in no rush because everything is working well right now.

Hi, thank you. Fixed it. VMAX 1350 mV. No spikes above.

on hwinfo64 what is the value that i need to check??? 

Bios came out of beta so i will check

Hi, haven't experienced Beta flaws for 18 hours by now. Ongoing testing.

I will check. Just add the last public bios now. and i will find if appears

i will run the test now. and monitor for now looks ok. But as i mention i use a 12700kf . but i will monitor it. 

Also install the public bios that was deploy today

I will monitor to the magnified approach

Now I've got that there's a new BIOS 4001 Non-Beta now. Updated. On the first glimps the Vcore is still high. 1.421 V max. Monitoring.

Thank you. Opened a new thread for 4001.
