What slots are the sticks in? What version of OS? What CPU cooler?

 

[luijo8989]

cpu cooler 212 evo
os windows 8.1 64 bits
slots 1 and 3
i tried switching it to 2 and 4 and the same

OK, try in slots 1-2 and see how it is - if OK then it's probably a channel problem and may well be the CPU cooler, can try loosening then snugging down screw tight, many overtighten in a corner or side which can throw the MC (memory controller) off. Another possible is bent/broken pins on the CPU

i will try that on the cpu cooler and i let u know

Try re-seating the RAM.
Had to try several times on my AMD APU laptop for it to recognized 7.0GB out of 8.0GB usable.(1 GB for graphics memory)

mine is a custom pc , the gpu has it own memory
