its not plugged contained by all the instrument or one of the chips is bad making the integral memory stick bad.
it hold to be the same ,, 256.. to 256... 512.. 512.. you can not put contained by a 256 , and then put surrounded by a 128..
See if the slot is disabled or off surrounded by the bios
Some motherboards have a different layout afterwards others. Like 1&3/2&4 fill one and two beside em for dual chanel. if they are not stagerd and put together in a row close to blue and black fill the blue which are closer to the cpu not blue and black.
