Z690-A GAMING WIFI D4 + EAC issue since BIOS update

[hatvaniz]

Hi all!

I have an issue with my Z690 board. Everythink was fine with the mobo until I updated the BIOS to the newest version (4001). Since then every game with anti cheat (Fortnite, Batllefield V and soo on) crashes and reboots my PC. Has enyone the same prbolem?

I'm sure last time as I played Fortnite (2024 september) everything worked fine and no hardware component was changed (4x16 Gb 3600Mhz Hyperx Rengade, ASUS TUF 6800 XT, 750W PSU, 1+1 TB SSD).

Hmmmm, some update : 

If I turn off trusted computing in BIOS, Fortnite will start, but if I start a game the PC will reboot in 1-2 minutes.

Hi there, this actually isn't a bios issue and was found out to be a windows 11 issue. Make sure windows 11 is up to date as it shouldve been fixed.

It seems to be a memory issue. I use 4 16Gb Kingston Fury Renegade 3600Mhz CL16 module. Te memory type is listed on the QVL but only in 1,2 slot (not 4). I tested my PC with OCCT and it crushes in combined test if all 4 modeules are installed. With 2 modules it crashes later. Only with default memory speed (without XMP) is OCCT stable (Forntinte is still crashing with default memory settings)
I will do more RAM test, but if somebody can help with memory settings, I will be very grateful.

Some progress with XMP. I slightly raised the  VDD (1.35V->1.4V ), VCSA (1.35V) , VDDQ (1.3V) values. OCCT is now stable in combined test, but Fortnite is still crashing at start.

I'm sure Fortnite was working on Windows10 6 month ago with the same configuration. Should be the problem the PSU (btw. no crash in OCCT power test)?

Uhhh, my mistake. The Memory, Adaptive 3D, was disabled in OCCT. The system is still crashing. All other OCCT test working flawlessly.

I run memtest86 on my system. Only 3 passes (it took 2,5 hours), but with 0 errors. The OCCT/Fortnite error still remains 😞
