How to find the FSB of RAM

[Tipu Sultan]

I am using asus p5kpl am/ps motherboard and I have kingston 2 gb DDR2 ram, now I want to upgrade my ram with another 2gb capacity but the retailer asked me about my current RAM FSB.then after surfing some net I used CPU-z to find out FSB,there in clock section it says rated FSB=1066.67 and in memory section it say's DRAM freqency 399.9MHz,now I am confused which one is the correct FSB for my RAM.Please tell me!!

Your ram is running at 400Mhz (doubled to 800Mhz). Quite typical for DDR2.

That means I should buy 2gb ram of 800 MHZ is that correct?

Yes. There are some other timing parameters that CPUz will show on the SPD tab. Do a screen capture of the SPD tab from CPUz and take that with you when buying RAM.
