im running 1x8 ddr4 2400mhz only going 1200mhz task manger says ill check if its in right slot if i can if not ill send pic
Okay so that clarifies you are running only 1 but its only using half. you said you had 8 gigs but your MoBO is only drawing half its RAM "
It shouldn't matter what slot its in as it is only a single stick of ram.
I would mash delete the next time you start your PC and navigate to the button to clear all BIOS settings. "
when i saw that it only showed 4 gigs and half the speed i thought maybe he had 2 cards that's why I wondered if they were in the right slots but youre right with one stick it wouldn't matter.
Listen to NightHawk his suggestion is probably going to solve your problem i needed to determine whether you had one or two sticks
