Problems with 4 sticks of RAM DDR 5 (128GB) BSOD or QCode 31 loop

Hello, i have a Asus ROG Maximus Z690 Hero and i've been using 2 sticks of GSkill Trident Z DDR 5 6000 MHZ CL 32 (F5-6000J3238G32GX2-TZ5K) totalling 64 GB without a hitch. Due to the nature of my job i reached the conclusion i needed more RAM, so i bought another set of 2 sticks with the exact same specs. When i started the pc after installing the new sticks i got stuck for a while in QCode 31, which eventually would move on to another but it would loop back to it and never boot. After a few tries i got it to enter windows with a BSOD or apps closing automatically. I tried lowering the frequency to 4400 MHZ but most of the time i still can't boot due to the QCode 31 loop. Any ideas on what's causing this and how to fix it? Thank you.

Updating the BIOS to the latest version I was able to get the 128 gb stable (so far) with 5200Mhz and 1.45v. Eventually i'll try to lower the voltage a little bit to see if it can get it to the original 1.4v. I tried 5400Mhz and 5600Mhz, but to have that stable i would need to go to 1.5v or beyond, which is not ideal.
