Absolutely, 1.2v is way too low for anything beyond the bare minimum clocks... most RAMs will operate smoothly at 1.35v with XMP enabled or a light overclock. It seems like the issue has been resolved, though. The key takeaway is avoid mixing RAM kits unless you're prepared to spend a lot of time troubleshooting—they often don't work reliably.
I’d really make sure your RAM stays firmly in place, though sometimes it’s tricky to get them locked in properly. Just press that button, unless you’re experienced, I’m just sharing what came to mind—because that’s what happened to me. I recently swapped my RAM and it wouldn’t boot up, but it turned out they weren’t stuck at all.
