I have a dg965ry motherboard. My problem is that the two slots of memory of the channel A are not working, but when i put 2 *1gb to the channel B everything seems ok. If i put the same memory at the slots A the pc does not start and with some beeps. When this problem appear i constated that in my bios setup screen some features also became disabled even i updated the bios software by the latest version. For exemple there are not the options concerning to change the cpu fan speed.What is the problem? Is my memory channel A is broken ?
