Problems with X870e Hero motherboard and EXPO profiles

[CptMario]

Hi! I made a video of the problem im experiencing and a temporary fix. Maybe someone will find this post useful,  I hope someone from ASUS sees this and updates the BIOS with these fixes or provides some technical support in the comments below. Its very frustrating dealing with this and this is not the first time im having issues with asus motherboards. Thank you, please watch the video.   https://youtu.be/H8FdNK10H2w?feature=shared

Setting any EXPO  causes a blue screen, restart, or being thrown into BIOS. Generally, instability. I set the speed manually without changing any other parameters. It works. Nevertheless, ASUS did not do well... .

BIOS: 1203

M/B: ROG STRIX X870E-E GAMING WIFI
CPU: Ryzen 7 9800X3D
Cooling: ASUS ROG Ryujin III 360 ARGB Extreme
GPU: ASUS Astral GeForce RTX 5090 OC
RAM: Kingston Fury Beast DDR5 6800 MT/s CL34     4x 16GB
SSD: Crucial T705 2TB NVMe 2280 PCIe 5.0
PSU: ASUS SFX-L ROG LOKI 1200W 80+ Titanium ATX 3.1

Code 15 is training code, you need to wait for the process to complete. Can take 5 minutes or more for initial boot.

[MIBHI]

Yes, but after 10/15min the boot start but crash or freeze at code 64

Bad ram or board. I am having issues as well. Like, the only way to get my ram to work is using the first two slots, instead of the normal old way of 1st and 3 or 2nd and 4th. I am having random restarts. Not, "your PC is Restarting or encountered and error and needs to restart" Nope, just watching You tube Video, then freezes, black out monitor, look over to PC and see it restarting.

And the 64, could it be b4 because b4 means bad ram or socket.

The 1203 bios and V0203 firmware resolved all issues I had with RAM speed and timings.

[MIBHI]

V0203 firmware ?

[neopassive]

Yup. On the same page as the bios updates:

Can I please ask for clarification? does this bios update and firmware update work with my specs? I just upgraded to this motherboard and am already regreting it. the stuning amount of problems just to enable my RAM to work properly and that this has been going on since this motherboard's release? So it's a top tier gaming motherboard at top price that does not allow you to game properly? am i gettting this right?

will this update allow me to simply enable EXPO without a complete system failure? My system won't boot at all if I enable EXPO as of now, I am at a permanent black screen, will this update address this problem? This is stuningly mediocre for a motherboard of that price.
