OK guys this problem really got into me and finally fixed it and have step by step of how to do this.
After restarting time and time again I found that sometimes it read the RAM as single channel and sometimes dual. So heres how to troubleshoot:
1) make sure your RAM sits nicely in the correct slots
2)Take out, blow any dust out of them, change channel positions
3)make sure in run>msconfig>advanded the memory options are disabled+restart
4)instant flash or make latest updates of your motherboard using a formated FAT32 usb to put executable file and INSTANT FLASH in the BIOS or whatever is described in manually updating your mobo.
5) set DRAM voltage in BIOS just a little bit higher
6) old mobos like my ASrock sometimes read a single channel configuration and sometimes a dual. If problem is not fixed yet(see number 1), restart multiple times and see if memory reads as single channel or dual
7) try another kind of RAM or buy a new mobo :b
