I have just built a system and have been having problems with the bios and system only showing 4096 of memory when 8gb is installed? I have tried all the slot configurations and it still gives the same readings. I have tried different makes of memory and looked in task manager rescource monitor memory tab? I am using a GA-78LMT-USB3 rev 6.0 motherboard.
So if I put a 4 gb stick in it shows 2gb. I'm using Win7 64 sp1. Anyone had the same problem?
