Unstable system after updating to BIOS v1505 for Strix Z690-E

[ElectronSpin]

Hi,

I'm seeing some major instability in my system after updating to BIOS v1505 now. Is anyone else seeing this or is it just me?

I've had great stability running everything at stock settings (i.e. 6000mhz on RAM, default voltages and no CPU overclock etc) since about BIOS version 811. Each time I have updated the BIOS since then I've had no issues until now. I've been using the XMP1 profile the whole time just fine.

Since installing v1505 I get constant crashes booting into Windows 11 or after a few minutes just browsing etc if I can boot into Windows at all. I've tried giving a little more VDD and VDDQ (1.325v each vs 1.3v which was the stock setting for my RAM). I've also tried running XMP2 profile but no joy with the system still crashing constantly. I ran a Memtest86 which passed fine, but Windows still wouldn't run stable. I didn't get to trying running the "RAMTest" program in Windows, but pretty sure it would of failed very fast.

To be able to make this post I've dropped everything back to default settings, so my RAM is now running 4800Mhz and it seems stable so far in terms of me being able to use a browser for more than 2 mins!

Be vert interested to hear other peoples experiences with v1505.

Also any advice on how to downgrade the BIOS would be great... ASUS EzFlash utility in the BIOS won't now read the v1403 BIOS file so I guess I need to take a different approve to downgrading?

Cheers

After a CMOS reset of my BIOS, I ran stable for two days. This morning I have experienced boot looping for an extended period of time. A CMOS reset shouldn't be needed ATM since there are no overclocked hardware devices in the system.

At this moment all I can do is allow the machine to cycle until it is stable to boot and/or roll back bios to a previous version for retesting stability. I would advise others to roll back BIOS to a previous version and for those to avoid BIOS update 1505.

I have to remind myself that my system was stable for 6 months on BIOS Version 1304.

The system booting loop before the windows start to boot or before windows boot?

Hey guys quick question, just got this mobo, and my Dumb AS#$ updated the bios to 1505.
I have tried rolling back the bios to the previous version 1403 which I had on my other Z690 D4 version.

How can I roll back the bios on this mobo???

I have tried using the flashback button on the back, the button does not light up at all???

I have tried just putting in the usb stick in the bios usb on the mobo IO, mobo see the usb, but when I try to update it, it says this is not a good bios, something like that???

I have not tried pusing the CMOS button since all settings are all deffault?

Any help please.

Thank you in advance.

. I also have same issues, just bought a new ROG STRIX Z690-E GAMING WIFI, on June, 19, 2022, assembled it on June 27, after I received a new CPU Intel LGA1700 Retention Kit for a EVGA CLC 280mm Liquid Cooler. BTW Temps are fine. Initially I had stock UEFI BIOS VER. 0604 x64, date 09/24/2021, after several days started to keep getting a code 55 Q Codes LED issue. My Memory Controller can not seem to make up its mind. Memory Freq. was 4000MHZ using stock BIOS Version, but also changed in BIOS to 3600MHZ for my DDR5, all by itself. So like you I updated to BIOS V1505. I am using 4 CORSAIR Vengeance 32GB (2 x 16GB) 288-Pin PC RAM DDR5 5600 (PC5 44800), which is on the QVL. It ran for 4 -5 hours with no issues, except Armoury Crate after installing Corsair ICUE, could not find the DDR5 in auto scan. Kept getting notifications it was saying it was there, but could not find it in auto scan. I did have a AORUS GeForce RTX 2060 Xtreme 6 G installed at the time, (was a left over from a previous build). It now is Windows 11 Pro getting errors on boot, I stripped down everything, including all the apps., to just the basics, using a basic keyboard and mouse, Now when it is turned on, will sometimes boot to windows, sometimes not. If I open my EDGE browser my monitor goes on the fritz badly, lines everywhere across the screen. This has happened even during going into BIOS settings. In BIOS all the DDR5 is visible all 4 sticks are visible same exact specs. DDR5 is running at 4000MHZ. My mouse pointer will freeze on screen, nothing will install. I changed out HDMI cables, I am now using the back ports for the monitor. Uninstalled all the apps I could, took a while because monitor screen kept fritzing out, colors everywhere, horizontal lines all across screen. I initially installed installed Windows 10 Pro from a USB, and updated to Windows 11 Pro with NO issues, no error codes, no Windows or QCodes. Changed out Power supply too, not help. Have same monitor issues, freezing up issues, Windows error issues, whether using the GPU or MB outputs. Also changed out those cables. Also monitor will only run in HDMI mode. Display port not work either way. With the GPU all NVIDIA driver updates were installed. At last attempt even though latest driver was already installed from NVIDIA, update claimed I was only running Windows 10, would not reinstall it. Windows has no available updates either. I am posting here using a Desktop iMAC, only way I can stay up and running online. Also went to Intel updated all drivers, and ASUS website as well, verified they are all correct.

Intel i9-12900K, sealed box.
4 CORSAIR Vengeance 32GB (2 x 16GB) 288-Pin PC RAM DDR5 5600 (PC5 44800), not even tried running at XMP. Sealed boxes.
EVGA CLC 280mm Liquid Cooler, not over tightened either, just turned screws equally just snug.
EVGA 850 Watt T2 Power Supply Dell - 27" LED QHD G-SYNC Monitor
Windows 10 Pro from a USB, updated to Windows 11 Pro, via MS Update, BTW will only install Windows 10 if you turn off Fast Boot in BIOS Settings, set to other OS, after install go back into BIOS reset to Boot from Windows Boot Manager.
SAMSUNG EVO PLUS NVMe M.2 SSD In first slot. No errors on SSD
AORUS GeForce RTX 2060 Xtreme 6 G (had it on to but as I said removed it also). Any ideas I would appreciate it?, thinking at the moment I have a bad Mother Board. Read online somewhere was possibly a recall on this board due to the Memory Controller.

I'm also experiencing this on TUF Z690 Bios version 1404+ as well: https://rog.asus.com/forum/showthread.php?129498-System-Is-Unstable-After-Upgrading-TUF-Z690-Bios-Pa....

I believe the issue has to do with a change in bios 14xx for Z690 which made all z690 boards unstable. When I roll back to bios on 13xx or prior, zero instability with exactly the same settings.

Hi.

My system:
ASUS ROG Strix Z690-F Gaming WIFI
Intel Core i7-12700K
G.Skill Trident Z5 DIMM Kit 32GB, DDR5-6000, CL36-36-36-76

it is not stable on xmp I or xmp II.
FW 1003 - stable on manual ram settings, random errors in memtest with xmp settings, no errors with manual settings
FW 1505 - tried only xmp, not stable - no errors in memtest
currently on FW 1304 - ran one day stable on xmp I, set to manual ram settings, now stable

All i did it was set the xmp I settings to manual profile to solve the problem.
Never had this problems with xmp on older systems, there is definitely a problem with this new DDR5 platform now.

I have the same issues with the BIOS Update 1505... Today I tried the new version 1601... unfortunately still absolutely unstable with more freq. than 4800Mhz.

ASUS please bring fast an update where the xmp profiles of G.Skill will work again!!!

THX and best regards
