Note for Memory Configuration

On TX chipset motherboards, there is a memory limitation when the system has more than 2 DIMM sockets.

The limitations are :

1.Maximum memory size is 256MB total for all RAM socket.

2.DIMM 1 won’t support 64MB or 128MB DIMMs with 64Mbit SDRAM cells.

3.If DIMM 2 and/or DIMM3 has 64MB or 128MB DIMM’s with 64Mbit SDRAM cells, DIMM 1 must be empty.

Follow the memory combination table below for instruction :

You can recognize 64MB or 128MB DIMMs with 64MB SDRAM cells in the following way :

nWhen a 64MBDIMM only has 8 memory ICs, it’s composed of 64Mb cells. (It may have additional glue logic ICs however.)

nA 128MB DIMM is always composed of 64Mb cells.
