Dual channel ram problem

I have just purchased a second stick of 512mb DDR PC2700 ram, I've put it in the slot next to my other stick of 512mb ddr pc2700 ram (i have 4 slot), and i've just ran cpu-z, and it says that i have 1024mb of ram but it's single channel and that the frequency is 160mhz and not 333mhz. so why is it not
running in dual channel

this is my mobo.

please help.

p.s am new to techsupport
 
Check your motherboard documentation. You may have to use slots 1 and 3 (or 2 and 4) for dual channel operation.
 
Thanks for your reply mailpup,

have put my original 512mb ddr pc2700 in slot 3 and my new 512mb ddr pc2700 in slot 1. now cpu-z say am running in dual channel, but performance mode is now disabled. What does this mean? also

frequency 160mhz,
fsb:dram 5:4
cas# latency 2.5 clocks
ras# to cas# delay 3 clocks
ras# precharge 3 clocks
cycle time (tras) 7 clocks

is this right

i thought the frequency was suppost to be 333mhz or at least 320mhz.
