ROG STRIX X870E-E BIOS 1512 - User Experience Thread

[Moriendor]

So, we just got another new BIOS in the form of v1512 😀 .

The release notes:

1.Updated AGESA to ComboAM5 PI 1.2.0.3e for upcoming CPU compatibility.
2.Enhanced system performance and stability.
3.Important: This update is irreversible. Rolling back to older BIOS versions is not supported.

Before running the USB BIOS Flashback tool, please rename the BIOS file (A5557.CAP) using BIOSRenamer.

^ No. 3 seems like a really important note. This BIOS is the POINT OF NO RETURN 😱 .

That said, I had no issues updating to 1512 from 1504. Everything seems to be working fine as before. I tried a cold boot and, as with 1504, memory training only occurred once after updating the BIOS and now I can boot to Windows in 30 seconds or so.

Since this includes yet another new AGESA version, I ran a couple of quick benchmarks which indicate that performance remained the same (very small deviations within tolerance).

- 3D Mark Speed Way: 14,621 (v1512) vs. 14,628 (v1504)
- 3D Mark Steel Nomad: 14,242 (v1512) vs. 14,206 (v1504)
- Cinebench 2024 Single Core: 135 points (don't have 1504 score)
- Cinebench 2024 Multi Core: 1351 points (don't have 1504 score)

System: ASUS ROG STRIX 870E-E (obviously 😆 ), AMD 9800X3D, 64GB (2x32GB) RAM Kingston FURY Beast DDR5-6000/CL30, RTX 5090@576.66

An irreversible bios.  Subscribed!!  I'm still on 1103 beta, and about to go to 1504.

2 updates in one month implies some serious bug fixes.

But 1504 is working fine for me.

Going to wait for some feedback from others before I update.

Is it really stable at expo 1 or 2?

I have same memory  but 9950 x .

Thank you

[schmosef]

I have a 9950x and 2 kits of Kingston Fury Beast RGB 64GB. So 4x32GB.

It took me a while to get everything stable. I'm using EXPO II and running the memory at 4000MT/s.

I have a thread where I explore getting my PC stable here: https://rog-forum.asus.com/t5/amd-800-series/rog-crosshair-x870e-hero-memory-compatibility-problems-...

[Psychoalien]

You have 6400 mhz , so most cpu can't  always handle the uclk or they have to run at 1:2 mode , 6000 mhz should be stable at cl 30 at 1.4v

That's a solid 'yes' for me. I have never had a problem with my memory kit (Kingston FURY Beast 2x 32GB DDR5-6000/CL30) on any BIOS version. It has always simply worked by enabling the 'EXPO I' profile, everything else on 'Auto'.

I really need to read some good feedbacks to change my current (1303) bios to this one honestly 🙂 (X870E Hero)

"Important: This update is irreversible" This is scary af ngl.

[Adiemus]

Also a Crosshair Hero here. I was one of the affected users who had major issues (memory training on every boot, bootloops, occasionally repair bootloop, couldn't get into windows) , so I rolled back to 1401 and everything is fine now.

Seeing as this update is irreversible, I'll hold off of updating for the foreseeable future.

[schmosef]

Considering this is "irreversible", Asus needs to be more forthcoming about what specifically is fixed or upgraded in this update.
