So I have a DDR1 type of RAM, and it's too expensive to buy as much of it as I need for an upgrade.

Supports six memory banks using three 184-pin DDR DIMMs
Supports up to 3GB PC3200/2700/2100/1600 DDR SDRAMs
Supports both 64-bit and 128-bit DDR SDRAM
Note: nForce2 does NOT supports x4 memory device. 1GB can be made by other density of dram chip such as x 8, x16.
That's from one site I found, does it mean that there's no chance in the world for DDR2 to work with it?
