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

It might be a bad board...try with a different one. I had issues with my x870e Hero myself, had to return it and get a new one to fix the issues with expo

I had a similar problem with G.SKILL 32GB KIT DDR5 6000MHz CL30 Trident Z5 NEO AMD EXPO ( F5-6000J3038F16GX2-TZ5N ). Constant freezing etc. with Expo (Expo I, II, Advanced).
I tried Kingston FURY 32GB KIT DDR5 6000MT/s CL30 Beast Black EXPO ( KF560C30BBEK2-32 ) and the problem is gone. Now I'm going to Advanced. Bios 1003, 9800X3D, Corsair RM1200Shift, M1 Samsung 990Pro 2TB, M5 990Pro 1TB. RTX 4080 Strix.

Hello!

Have same problem.

When set EXPO (any, I or II or TW - doesn't matter) -> code 15 (one or two min) after -> bios -> cant select bootable device, but my EVO 980 Pro in system!

After EXPO off - 1-2 min, then all fine. With out EXPO all work fine!

My configuration:

M/B: ROG STRIX X870E-E GAMING WIFI
CPU: Ryzen 7 9800X3D
GPU: ASUS GeForce RTX 3080 ROG Strix V2 OC Edition
Memory: ADATA XPG Lancer [AX5U6400C3232G-DCLABK] 64 Gb (32x2)
SSD: 1Tb Samsung 980 PRO [MZ-V8P1T0BW]
PSU: FSP Hydro PTM PRO ATX3.0 (PCIe5.0) 1200W [PPA12A1023]

Everything is the same as everyone else.
I had to set everything to Auto.

ASUS - please help!!!

Just made a new Pro Art build - X870e Pro Art, 9950x, 4080 Super, CORSAIR VENGEANCE DDR5 RAM 96GB (2x48GB) 6400MHz CL32 Intel XMP iCUE Compatible Computer Memory - Black (CMK96GX5M2B6400C32)

My issues have been computer freezing when idle or any low cpu process. I'm on the new beta BIOS right now 1103, and am trying no EXPO settings to see if it resolves the problem. I tried to enable EXPO 1 and set the RAM to 6000 instead of 6400 and still experienced freezing while system is idle.

I woke up this morning and my system didn't freeze overnight with RAM settings to AUTO - so let's see if a few more days confirms that it can't run EXPO - or if it can, not 6000 + at any rate.

this post is going to be extremely unhelpful unless you find what I am referring to but there is one setting on the first page in either Like overclockers area or a different tab. That has a setting something test: maybe like memory test or something. Disable that and it should help. I’m away from home and I haven’t done it in months but that was the most helpful. it was either a test. or like a memory scan scan or something maybe. it may have even had the word software. But if you disable it and then restart you should be good sorry for the bad post. — edit— it just occurred to me the setting you’re looking for has either enable or disable… And it exists in one of this sections of the first page, not under the advanced tap—

A new release of the firmware "Version 1104" has arrived.
It is the same thing ow 1103 but it doesn't cost anything to try :

Firmware 1104 - 2025/02/21 

For the RAM do you have tested to setup the timing manualy ?

[iggy0978]

I’ve tested down to 5600 and still having lockups at idle.(even when bumping up ram voltage) I’m now at full Auto on ram timings to see if it’s stable at all. 

[iggy0978]

Full AUTO on the RAM - still freeze at idle. On phone with Asus right now for an RMA (however they are out of stock)

BIOS 1104 solve all my problem, EXPO working perfectly.

[iggy0978]

Still freezes with new processor. Gotta be the motherboard at this point.
