I’m still new to tweaking with my rigs. This is a pre-built Acer Predator 5000 po5-604. When I first got into pc gaming I didn’t know much, if I knew what I knew now I would have built one myself. I currently got 2 new RAM sticks 32GB each. I went to enable XMP but found out my CPU only goes up to DDR5 4800. The speed is currently sitting at 4800, I could buy a i9-12900 which would allow me to enable XMP so it would run at would the RAM sticks say on the box 5200, I just don’t know if it’s worth getting a new 12th Gen CPU for the sake of 400MT/s.
Someone said the even if I get another 12th gen or 13th gen, XMP still won’t enable.
The problem is the sticks didn’t come together in the same pack, even though they’re the exact same 32GB stick.. could this be the issue?
