Running Corsair DDR3 1066 memory on an Intel DX38BT board. Very glitchy, problem being that occasionally I turn on the box and get the three beep error code "no memory". The memory came bundled from Tiger Direct with the motherboard and a Q6600 processor. I assumed the memory was compatible. Default on the motherboard is 1.5V. For some reason, I think the memory is 1.7V. The BIOS gives me the abilty to reset the voltage, have used the default and the 1.7V settings and still get the beep codes from time to time. I did a search and cannot now find the specification for the voltage for this memory. Checked the Corsair website but very little informaion available. The Corsair memory does not appear on the Intel tested memory list. Does anyone know the voltage on this Corsair memory? I am thinking of repurchasing memory from the tested list, but 4G memory is not a small investment.
