I installed a 3.3v 64MB DIMM into a board with no immediate problems. However the memory count is only showing 16MB. There was a jumper setting to set the voltage but when I set it to 5v machine would not boot. At 3.3 machine boots fine but with only 16mb. The DIMM is not PC-100 and the board does not support this anyway. Any possible ideas why the memory count would be off to such an extent? Thank you
