Hi, I recently buy 2*8GB Ram kit for my P6T Deluxe V2 Motherboard.
It worked fine until today. Bios can only recognize 8GB instead of 16GB but CPU-Z said there are 16GB in dual channel.
I switch those two ram stick and it still shows only 8GB.
Then I try to install one ram at a time. I can boot with one of the Ram stick but not with the other one.
Does it mean that ram stick is broken or something? Why CPU-Z can see it?
