ASUS TUF B650M PLUS WIFI - PC Not Booting With EXPO Enabled

However, after a restart, I can no longer access the BIOS — though Windows still boots fine.
No clue what is happening with your bios lol, you say you are able to get into windows but not bios which is weird because your PC has been able to post and reach into windows so why not bios then lol.
all of this sounds very asus-like, that is asus fast boot enabled situation. turn it off , if it isnt yet.

Check this video for how it is now
But if power off completely and start windows starting but no tuf screen from where i can go into bios
Even windows boot recovery section not showing…
Let me turn of fast boot and look into it then….
Update:

With fast boot off and memory context restore enable i can boot into bios after restart and it much faster now…

Running at expo settings, mean 1.4v and only setted ram as 5600mhz… the timing is: 40-40-40-77, cpu soc at auto…

I tried 5800 with same settings and also with 1.435v but no display other than just green blue boot qled…

5600 worked it seems with 40-40-40-77 and context restore enable and fast boot disabled…
Should i set lower timing now?
Or reduce the voltage and stick to this timing?
As it seems no hope for 5800 or 6000…

sidenote just in case - that fast boot from asus is annoying that thing just throws in OS directly, too quickly and it can do other random a$$ stuff too. (its as if it has its own mind/mood). and everytime one resets cmos it will be back , it will be back ON. so you will need to turn it off everytime cmos resets.
--------------------
also all the symptons you posted so far are matching towards am5 here 7700x having shitty mem-controller. the sticks are probably okay.
(then again i had read at one forum , that g.skill behaving weirdly after asus bios updates and it had become a norm. hence my previous texts were on about roll back bios and mem controller issues.)
--------------------

context restore enable
turn it off, i mean let it take its time. basically trying every variable possible

Asrock is rock solid for as Mobos then comes both MSI & Gigabyte. Last is Asus in AM4 and AM5 mobos also as suggested in hardware unboxed. Again Ram training takes some time during its 1st boot for any AM5 mobo.
In my mobo in its bios Ram is shown as 4800mhz and 5600mhz kit while in cpuz and HWinfo it's showing correctly as 6000mhz kit. I even updated my mobo bios.
 
Thanks everyone, you all are awesome…
Should i lower the voltage for 5600mhz or 1.4v is ok?
And also can i try with 30-40-40-96 now?
hence my previous texts were on about roll back bios and mem controller issues
how to rollback? is downgrade allowed?
if yes which version I should use?

I thought of fast boot as well which is why I said to try using the shift + restart method which works even with fast boot enabled.

Now that you have a setting that you know works you can go whichever way you like. You can try lowering voltage from 1.4v to 1.3v, you can run memory stress test programs recommended from here, I use TM5 with extreme config (will detect errors if any in under 5 mins, it's that good), you can try tightening timings for example try 36-40-40-86 or something.
You will want a config that's 100% stable and error-free so might as well go with memory test first before tweaking settings further.

Even Asrock had trouble with recent processors (due to BIOS I think?). I feel like none of the brands are rock solid until someone has tested them to the extremes with specific processors installed. On the paper they all look pretty good and to be honest for most part they are but because PCs are not a configuration of predetermined components like consoles are things can go wrong from multiple directions and you sit trying to figure out the cause lol.
 
I use TM5 with extreme config
how to use this program to load and use extream profile?
seems it auto stat when i double click and there is a option to select config and exit, not to start
This could be just a GPU related issue. From personal experience with a rtx3070, I've seen that uefi is only visible when connecting to iGPU, even with a dGPU installed. Try connecting your monitor to dGPU when accessing uefi. This is not related to the post issue.
This is strange, because on old mobo never encountered this, is this amd/nvidia issue?
You should not have to override and relax the timings once you set expo. You can override (reduce) the frequency and voltage. Leave timings at auto with expo enabled.
Will try this now with 1.3v
you can run memory stress test programs recommended from here
Holy cow!! Is it normal cpu temp go up 95c during this test?

Put extreme config file in the same directory as .exe > run as admin > load config and exit > run as admin again

He's using 3060ti so dGPU, unless that's a typo and you meant iGPU...
For me I have to do a complete shutdown and wait for monitor to auto turn off then start the PC then press del key to go to bios, I still miss it sometimes which is annoying so I just use the "shift + restart" method.

Yes it's normal. It's trying it's hardest to stress the CPU (if you have selected the corresponding setting that stresses CPU). If you are worried just use the other one who focuses more on RAM. You can not damage your PC this way because of safety measures set by the manufacturer so no worries.

How much it will run for?

No, I meant what I wrote. To clarify, I have a 9700x with a rtx 3070, and the monitor is connected via HDMI. During post, with the monitor connected to the 3070 dGPU, I never see the post message or UEFI (even if I enter it by pressing the delete key). However, after a few seconds, I do see windows login screen.

Now if I just disconnect my monitor from the 3070 and connect to the iGPU HDMI port, I can see post message, UEFI and windows login screen.

This is a known issue with 30 series cards running in UEFI mode and there were some firmware updates released by Nvidia as well as the board partners, but they don't work in my case.

So when I need to change anything in UEFI, I switch to the iGPU output and make the change and then switch back to the dGPU. I used an HDMI switcher to change the outputs.
Will try this now with 1.3v
Considering you're using hynix chips, you should be okay even with 1.25V. that's what I'm running for 6400MT/s but with uclk:mclk at 1:2 as my memory controller throws random errors above 3100MHz (6200 MT/s)

ok thanks for the clarification brother...

ok will try that....
@Silent47Assassin how you understand from CPU-Z that CPU and RAM running as1:1 not 1:2?

Is ur fast boot enabled?....

if yes which version I should use?
Yes, roll back should be easily possible. Basically Installing older version of bios.
Now which bios exactly? Idk.
------------
In such scenarios you can try oldest bios available on the asus website
( don't worry long time has passed and they already removed unstable/useless versions of bios over the time. And each bios's existence reason is given in note form along with bios version read them first )
But this bios method,
I would recommend to save it for the last when all this tickering doesn't work.
And don't haste when it comes to such situations.
let usbs' cool down.
Wait extra 5-10 minutes after successful bios install. why? Just bcuz one can.
Hot usb ( idk the exact temps but they sure like to fk up OS installs, personal experience. )
----------
If u have seen the video I had shared above you have probably seen that this overclocking doesn't necessarily yield best results in all* games nor those results can make significant dent in performance.
( Then again I don't play those multiplayer shooter games, and anything over or around 120 frames per sec is enough for me. )

1 hour at least if you are looking for 100% stable OC. 5 mins if you just wanna check OC quickly.

Ah okay. Must be an issue with system that has RTX 3000 series GPU and a processor with iGPU in it then. Any reason why you are using HDMI and not Displayport?

I run my audio via an AVR in the chain. Also, my PC cabinet is in the front of the room with the AVR while my display and seating position is in the middle of the room. Longer (5m+) HDMI 2.1 cables are cheaper and easier to find than equivalent DP cables.
 
I have a MSI motherboard by the way
I see, well similar behaviour but less invasive than asus was observed on my gigabyte Mobo too when fast/quick boot was enabled.

-------------


Some observations I just remembered -
That reminds me;
This might come in handy for all.
User password at bios lvl might come in handy/to rescue at a times.
It will pause/hold booting process until you enter password.
And can give u chance to boot in bios.
Even if fast boot can skip screens and logoes and other stuff it can't skip this.
But gotta be quick.

So far there was only one time, that too on asus,
a fast boot could boot me directly to os without letting me choose other OS but that was bcuz of nvme + quick boot I guess,
it was too quick I pressed enter after inputting password I was already welcomed by the windows....
:⁠-⁠P
( Nvme speeds can be scary at a times )
