RAM problem

[Kilew]

I have two sticks of 512mb Hynix PC3200 RAM. However, they both have different (configurations?), and my motherboard doesn't seem to like this.. One stick is 16x(32Mx8) and the other is 8x(64Mx8). What the motherboard has done is it's stuck a 2/3x multiplier in there, and SiSoft Sandra reads this under Logical/Chipset 1 Memory Banks

Bank 0 - 256mb DDR-SDRAM 2.5-2-2-6 2CMD
Bank 1 - 256mb DDR-SDRAM 2.5-2-2-6 2CMD
Bank 4 - 512mb DDR-SDRAM 2.5-2-2-6 2CMD

The memory is also running in single-channel mode instead of dual channel.

Is there any way I can fix this, and get both sticks running at the normal 400Mhz speed in dual channel?

And one more question, if there isn't any way to fix it, will I suffer a huge performance loss, and more importantly is the computer utilising the whole 1024mb? (i'm asking this because of the Bank 0 thing)
