I recently bought four sticks of GSkill DDR4 3200 16GB RAM, but my PC only boots when I mix these with two older sticks of GSkill DDR4 3000 16GB RAM. I've reset the CMOS and tried different configurations, but the system only works when the old RAM is in slots A2 and B2, along with the new RAM in slots A1 and B1. It's frustrating because even with XMP enabled, all four sticks are reading at 3000MHz. My motherboard is a Gigabyte X570 UD, and I'm scratching my head over this. Any ideas?

It sounds like your system might not handle four sticks at 3200MHz. Why not try running all new sticks at 3000MHz? Sometimes, stability goes down with four sticks compared to two, which could explain why it's acting up.

I see your point, but it doesn't boot with all four new sticks at any config. It seems stuck at the old sticks for some reason.
