Well DDR3 has quite low memory requirements, especially at lower clocks/speeds. Remember, Intel X25-M is still using PC133 SDRAM (not even DDR) in their SSDs; so performance is not paramount here but rather capacity of the DRAM. The G1 even used 166MHz SDRAM is i recall correctly, so the G2 has slower DRAM but is faster. ;-)
1GB may be used as write-back so the first 1GB writes 'for free' at maximum wire-speed. Would also be very beneficial for random write purposes like databases. Two 4Gb (=1GiB) DRAM low-voltage chips would be perfect for this task.
