Does the system boot normally with the original ram?
Which slots are you using? Should be using a2 and b2 ~ 2nd and 4th slot from cpu. Try each stick separately in a2.
Did you turn the pc off and unplug the power cable before installing the new ram?
Check haven't accidentally connected video cable to onboard igpu if have discrete gpu.
I switched back to my old rams earlier and no problem, i didnt change slots i used the same a1 and b1 slots.
lol i had my pc powered off and power cord u plugged when i installed it, im not a complete newb
no changes to where i connected my video cable
from researching, saw some asrock forum members having same issue but resolved it by updating bios which i havent done in few years since i never ran into any problems. gonna try this tomorrow and get back to you.
btw side question these crucial ram were tight to install on the mobo. i had to use quite abit of force to take them out or to seat them. Im worried about possible damage to these ram slots and ram itself had to pinch and pull them by the body of the ram. what are some symptoms of damaged ram slots/ram?
