ROG MAXIMUS Z790 HERO BIOS 2503 - Slow Boot / Post times

Sentinal13
Level 9

Prior to updating to the latest BIOS my BIOS start times were sub 13 seconds on a restart, after this latest update to 2503 and 0x129 my Bios start time is +16 seconds with the same settings. This delay is even more pronounced when I try and access my bios using delete or F2 it appears to continue doing something in the back ground and takes an absolute age to get into the settings. Previously it was near instantaneous to get into the bios settings.  Has anyone else experienced these sorts of issues or any pointers ?

@topless2006... in regards to your long boot time, do not jump through the ASUS hoops troubleshooting something that has already been tested for them. I have removed SSDs and even purchased a new one and reported to them. They have brushed this off and have all but advised me that the problem is not their bios but my system or hardware, even though the issue does not exists in 2402 Bios. Everything points to a change in the BIOS they refuse to recognize.

So here is their resolution after they have refused to recognize that the long boot time only exists after BIOS 2402.

Hello @RickJamesBish 

As mentioned in our discussion regarding the testing video, after multiple tests, we replicated your hardware specifications, including the memory model, SSD specifications, and slot placement, as well as the BIOS version.
We did not encounter any issues with extended boot times, and the boot duration in our testing was approximately 25 seconds. Based on this, we recommend cross-testing with another SSD or a fresh system installation.
Alternatively, you may continue to monitor the system or consider whether there is a need to update to a specific BIOS version.

Thank you.

To me that is a piss poor resolution for a motherboard that cost in excess of $500 but I had already purchased a new SSD and tried a fresh Windows 11 install on that new SSD.  The boot problem still persists. I also went back to bios 2402 and the extended boot time is not present. The only other factor remaining is the motherboard itself, in which case they need to replace since it is still under warranty.

There is defiantly something wrong with BIOS 2503 and now 2602 beta. I have a ROG MAXIMUS Z790 HERO EVA-02 and every app and every game on my system was running perfectly. Then I updated the BIOS to 2503 and suddenly my Windows boot time was super slow, I suddenly had games and apps crashing within 3-4 minutes, and my entire system was unstable. After I went back down to the 2402 BIOS... every single issue returned to normal. The 2503 BIOS itself is 100% the problem as myself and many others have been reporting. And now people are reporting issues with BIOS 2602 beta.

With my hardware (see signature), the boot time has not changed due to any BIOS update.
It is always around 12 - 13 seconds (according to Windows 11 Task Manager).
It currently has 2602 BETA. I have 4x M2 NVME + 2x SATA HDDs connected.
I don't use OC, only XMP is active and Intel standards in the UEFI.
Could it be that the Asus M2 adapter card or various riser cards are causing the long boot times with the more recent BIOS updates for you?
I can confirm that the RAM temperatures were removed in ArmouryCrate with the last update.

I'm staying with bios 2402 for now. In bios only change to XMP profile without OC. Ram CMT32GX5M2X7200C34 QVL at 7200 Mhz, CPU 13900K. Everything stable. When changing to a newer bios, system startup extends to over 1 minute (I don't know exactly). I have more drives, including two asus m2 adapters (Asus PCIe 3.0 x16 - 4x M.2 M-key Hyper M.2 X16 Card V2 (90MC06P0-M0EAY0). In total I have 6x nvme gen 4 and 3x SSD sata and 1x HDD sata. In total 10 drives. So far I have no problems except for the startup time on the latest bios. I'm skipping problems with armory create which I use to update components and control fans.

The other potential issue is the microcode, which someone else mentions on the first page. If it contains changes that are beneficial, the user cannot take advantage of those changes if they are not using the latest bios. Might not be that critical but its another reason ASUS needs to step up to the plate.

Here is an idea, how about making the 2402 firmware available but with the latest microcode, if that is even possible?

I do not use the riser card either, OC or XMP. Also I removed all Drives, including OS drive, replaced it with a new M.2 drive, new install of windows 11. The boot time with the last two bios updates is still notably slower than with 2402.  In fact, as I pointed out to them, boot times with all of my M.2 drives installed and a physical HDD, boots faster with 2402 than a fresh install with only one drive using the last two bios versions. Everything points to something in the bios update.

I have gone down to bare bones, where the only factors are the OS, Keyboard, Mouse, Monitor, GPU, Ram and M.2 drive. The same still stands that anything above 2402 results in an extended boot process. They request that I try a different M.2 drive, which I have already done. They seem to want to shift all the troubleshooting to the end user.

I do not use the riser card but as per everyone else there is a major difference in bios before 2503 and all the later iterations, I do not know if Asus are using an AI process that replicates a call centre in India or if they are just p!55 poor, this is beyond a joke for a £600 motherboard

I have reverted back to 2102 bios  I was getting random crashes to the desktop whilst playing CounterStrike,   These are the bios options I have changed from the Auto / Defaults   I am running an undervolt of 0.085v

I have just flashed to 2402 and the loading speed of Windows is about the same as 2102,  getting into the bios settings is also the same,   I have used the same settings as above undervolt and ICC limits etc,   There is definitely a speed difference between 2503/2602 and the earlier bios versions, even trying to enter the bios settings shows this delay .  On a side note I do have a DVD/CD RW attached via sata, which is checked on startup, also a flash card reader connected to internal USB .. A full restart is 1minute 6 seconds from clicking restart to the desktop appearing,  also task manager is reporting bios start time of 13.3 seconds,.   with 2102 this was 12.8 - 13 seconds on average.. with 2503 this was +16 seconds.   I have no idea where this 3 seconds is being used but it can be seen and is noticeable on the later versions.
