I have the DQ965GF desktop board with a core 2 duo e6320. I have two sticks of 1gb 800mhz ddr2 ram installed. The problem is that if I don't manually set the RAM to run at 667mhz, the pc freezes after a few seconds (and restarts sometimes). Why the memory doesn't run at 800mhz? The board is supposed to support up to 4x1gb at 800mhz.
The issue may depend on the memory that has been installed and the Serial Presence Detect (SPD) settings that it uses.
What is the manufacturer name and the part number of the memory you tested with?
In addition, be sure to be using the latest BIOS posted on that motherboard at:
You can also test the motherboard using one of the tested memory modules listed here:
