what utilities (you mean a manuall) ??.... I pot all the rams in no order and they acuipied all the space......also there is a button near the rams in the motherboard , they said it is for configuring the ram but I don't know how to use it ????
Gigabyte boards for example come with a utility called Easy tune which among other things tells you what memory slots are populated and the specs of the chips. Yours likely has a similar utility.
If not, there are a number of freeware utilities that will do the job. CPUZ comes to mind.http://www.cpuid.com/cpuz.php
Once installed you will see a tab marked "memory". This is usefull, but right next to it is a tab mark "SPD" which shows each memory slot on your board, shows if its populated and what is in it.
Compare what cpuz sees in your slots to what you actually have and report back.
