i got an i9 in there, pretty outdated GPU.
i bought the ram as an set, it sees them both in the bios but will only load with 1.

any help?

runs perfect on 16gb, but planning on updating gpu but before i do that i want this fixed.
this problem took me 6 days or something just to get windows installed so i'm pretty pissed at the moment.
but like i said, works fine, runs games etc. with 1 stick of 16gb
