Bios after 1601 problems

[Sec3Op41514]

Hello all. First my specs:

Asus z590-e wifi gaming

I711700k

32 gigs ram (2 sticks 16)

2 m.2 ssd

Rtx 4080

So I been having usb devices disconnect all at once randomly every now and then.. decided to update bios. My dumb self didn't think it'd be a problem go from 1601 to 2001 bios. I now understand that I shouldn't have.

Anyways, now nothing works right. I get into windows maybe 2% of the time. And when I do it freezes or crashes. Or bsod.

When I load a game it acts like the cpu isn't working right or something very slow/laggy. 

It will not let me roll back to 1601 bios. I went down step by step from 2001 to 1903 to 1801 to 1701 then back to 1801 just to see. Currently sitting at 1801. 

Yes I upgraded Intel management before trying.

I'm at a loss... my mobo is still under warranty but I'm hoping someone somewhere has a solution so I don't have to be weeks without my computer. This is not just for gaming but for work as well. 

Please any help would be appreciated

Hi @Sec3Op41514 

Sounds like it's possibly memory instability. Updating the CPU microcode / ME firmware can have an impact on overclocking occasionally. 

Are you able to check if the behaviour is the same at Optimised Defaults? (Don't enable XMP).

I keep everything at stock and don't overclock.. so it all sits at defaults

To confirm you're unable to use USB Flashback to flash to 1601? 

[Sec3Op41514]

Idk why the response part is being weird 

Correct. Idk why. It just goes to a solid green light (which afaik means it isn't working) when trying any bios prior to 1701. I can use the flashback button to flash any bios from 1701 to 2001 easily. . unless I'm dumb and missing something...

Someone on reddit suggested that it could be my m.2 set up... Where I have one and slot one and one in slot two But it's been that way for the past year and a 1/2. Does anybody think that The bias update could have caused It to read Things differently.

Update:

Took it to repair shop, they've tried other hard drives etc, fresh windows install.. they believe something screwed the mobo. 

Has nobody had this issue or similar? This is very frustrating

Hello, @Sec3Op41514 

Based on your description, we recommend checking if the installed memory is listed in the QVL. You can find instructions in the [Motherboard] How to query (CPU/memory) QVL List?
Also, be aware that updating the BIOS may carry the risk of not booting up.
For guidance on this, please refer to [Motherboard] How to update BIOS of the motherboard? (Include different generation CPU).

Considering your recent comment updates that you've sent for repairs, we suggest relying on the assistance provided by the repair center.
Alternatively, if you have any other concerns or questions, feel free to PM with your motherboard serial number and RMA number.

Thank you.
