Does 400 Mhz memory work in a G5 Dual Core 2.3?

[Mac Hammer Fan]

I bought a second hand G5 Dual Core 2.3 to replace my old dead G5 Dual 1.8. Standard memory is 533 MHz PC2-4200 DDR2 SDRAM. However it came with only 2 GB RAM. I have 4 RAM modules 400 MHz PC3200 DDR SDRAM from my old Mac. Is there a chance they will work in the new G5 Dual Core?
TIA

Unfortunately, it will not work.

DDR1 RAM does not work in a machine that requires DDR2 RAM.
