Hey,

Yes DDR400 is the same as PC3200. Also DDR333 is the same as PC2700. Here is the full run down.

PC1600 = DDR 200MHz Data-rate (100 Clk x 2) 1.6Gb/Sec
PC2100 = DDR 266MHz Data-rate (133 Clk x 2) 2.1Gb/Sec
PC2400 = DDR 300MHz Date-rate (150 Clk x 2) 2.4Gb/Sec
PC2700 = DDR 333MHz Data-rate (166 Clk x 2) 2.7Gb/Sec
PC3000 = DDR 366MHz Data-rate (183 Clk x 2) 3.0Gb/Sec
PC3200 = DDR 400MHz Data-rate (200 Clk x 2) 3.2Gb/Sec

And it sounds like your mother board does support dual channel.

That's what he ment when he said it would only be 400mhz with just one module.

Meaning to use the full 800mhz which your mother board supports must use dual channel ovious since that means 400mhz Times 2 which is of course 800mhz.

So yes, you need two sticks/modules of DDR400. Size is up to you. I personally would go with two sticks of 512mb. Meaning a total of 1gb. But 256mb is just fine for most. Mean total of 512mb.

Of course your system wont be any faster overall excpect when you need the extra 512mb of course like when running photoshop or playing doom 3 in ultra mode.

Take Care,
