I recently bought 2 extra sticks of the same RAM i had in my motherboard, increasing it to 32GB with a speed of 3000MHz. Although the capacity shows up correctly, the RAM speed is shown as 900MHz or 1400MHz with game boost and an A-XMP profile on. I've also checked if my mother board is supported for such RAM speeds and it sure is, it says that it could go up to 3200MHz and even more.
I've recently done a factory reset wiping all drives and also migrating my OS to a different drive, yet the issue still persists, with game boost and A-XMP my computer also seems to crash sometimes.
I have provided a screenshot of CPU-Z RAM currently running + the SPD tab, perhaps the timings or/and voltages ar off.
Specs:
Ryzen 5 2600X
GTX 1660TI GDDR6 6GB
MSI B450M BAZOOKA V2
G-SKILL AEGIS 32GB 3000MHZ
