I have 8GB of memory installed in my computer ( in dual channel), but when i go to PC Info it says i only have 4 GB installed. Also when i use Belarc Advisor, it tells me that only one of my sticks is working and being read. But when using CPUID, that program tells me that i have 8GB of memory installed in single channel. Can someone tell me what is wrong and if i have a dead stick or not?
