How do I know if my memory is running in dual-channel mode?

How do I know if my memory is running in dual-channel mode?

I've got two sets of these for a total of 2GB.
Corsair TWINX Dual Channel 1024MB PC3200 DDR 400MHz Memory(2x512MB)

My mobo is Asus A8N SLI Premium with the 4800 X2 cpu.

The machine boots fine into XP and in 'my computer' properties, it says 2gb ram.

Are there any utilities that can help me figure this out?

Thanks!

when the pc boots in the post screen it will detect the ram, add it up and it should say Dual Channel, or Single Channel, at least my old board does this. or goto www.cpuid.com and download cpuz and then check the memory tab it will tell u if its in single or dual channel. lastly check the motherboard manual for where the4 sticks should be in to make it run dual channel.....

usually if u have to ask if its runnin in dual channel, its not. lol

Here's what shows:

So I guess it's dual... ? Also, I see 160Mhz... 166Mhz... 200Mhz... but my memory specs say 400Mhz... is something wrong?

Thanks!

166ddr = 333mhz
200ddr = 400mhz

make sense? the fsb is mutiplied by 2 for DDR. so 100ddr is 200mhz, and 133 is 266mhz and so forth...
