How you downgrade ?

I can't. Stuck with 2305. Sorry I wasn't clearer. Bios flashback doesn't work either.

Fan Xpert 4 in Armoury Crate seems to work abnormally on 2305. CPU fan and pump speed suddenly rise and then fall even at idle. Turning off Fan Xpert 4 and let BIOS to control fan speed can resolve the issue.

Fan Xpert 4 got update today, it works perfect now.

Still ok at XMP1 64gb ddr5 at 5200MHZ

Cant see anything different between 2204 and 2305

The XMP now works with 4 sticks of DDR5 6000, but there is still a bug that won't allow it to boot from my M.2 drive. I'm running it at 5400 which didn't happen before unless I increased the VDD and VDDQ to 1.375, and I would still get BSOD once in a while. Running solid at 5600 40-40-40-76 1.35v on 4 sticks of XPG Lancer ARGB 6000. Will try running off a SATA SSD tomorrow and see if I get different results.

Note: IT IS RUNNING AT 5600! Couldn't find a way to edit the post

Hi 90sPaqMan. How much RAM do you have installed? What brand is your RAM?
Since upgrading to 2205 I have not been able to use my 128GB RAM (4x32GB) Kingston Fury 5,600MT/s

Asus ROG Maximus Z690 Hero Motherboard - Intel i9-13900K - Asus Thor 1200p - Kingston Fury 128GB (4x 32GB) DDR5 4200MT/s (Trying to run 128GB at 5600MT/s) - 3x Firecuda 530 NVMe SSD 1TB - WD Black SN850 NVMe SSD 2TB - ASUS ROG STRIX RTX 4080 - Windows 11 Pro x64

I cannot use XMP 1 profile, with 2 kits of Kingston FURY Beast 32GB DDR5 4800MHz CL38 Dual Channel Kit (64GB total).

Memtest gave me errors.

So I can only use the default/auto settings ( 4000 Mhz)

Although 2305 still working great for me on 690 Hero, I cannot roll back the BIOS using EZ Flash 3. If I had known this, I wouldn't have tried it yet. I just wish this information was made available on the support page notes, so just letting you all know.
