I have a Shuttle Spacewalker AI61 motherboard in my system. The specs indicate support for 768 MB. I have 2 256 MB DIMMS installed in the first 2 slots. The system will not see all of the memory. I have swapped the DIMMS nack and forth and tried them both alone and they indicate correctly but not together. There are no jumpers. The BIOS interprets the memory sizw.
I have a new release of Dragon Naturally Speaking and it will not even install without 512 MB.
Does anyone know this board or have any suggestions? If necesary, can I supstitute 1 512 MB DIMM for the 2 256s? Can PC133 SDRAM be substituted for the PC100?
