[SOLVED] Can't get my ram to 3600 mhz.

Specs
Mobo: Gigabyte Z690 UD DDR4 1700
CPU: I5 12600K
RAM: Corsair Vengeance Pro DDR4 3600Mhz 4X8
PSU: Seasonic GM-750 80+ Gold

I recently bought my first pair of 2x8 Corsair 3600 ram slots (upgraded from 2x8 HyperX 2400mhz) and within 5 minutes of basic configuration on the BIOS I managed to make them run at 3600 Mhz (using slot 2 and 4).
Today I received my 2nd pair of memories (packaging is basically identical, I noticed a minor change which i'll show below) and I couldn't make them run above 2666 mhz (only way I could make the PC work, otherwise its an endless bios loop)

(The first 2 are the ones I used this last month, which I managed to make run 2x8 @ 3600 Mhz with no big issues, the big box containing the 2x8 is the new ram which I couldn't make them run together with the other 2 slots at 3666, I might be overlooking into this but I thought maybe it was useful information)

So this is it basically, any thing I could try to make the 4x8 run together at 3600?

EDIT: This is the tag on the RAM (all 4 are identical)

UPDATE: I fixed it by updating the MOBO BIOS from F2 to F6 (it's not the latest one but it still worked),
