hi
i had to rephrase my question as i did not get any reply
i recently purchased an asus a7n8x-x mobo.i have an 2600+ barton cpu and 384 mb 266mhz RAM .

the problem is the ram fsb is always shown as 133mhz at start up(POST) although the BIOS shows the resultant ram fsb as 133mhz.i have 266fsb ram.
i tried with ram of different fsb but still 133 was shown.

i tried the pc 2700/333fsb ram .the bios showed the fsb speed as 166mhz
but at start up the running frequency is shown as 166mhz instead of 333 ,with the line"single channel mode"beside the ram speed(basically the fsb does not seem to be doubling up,the same fsb as in the bios is shown)
please help!!!
earlier i had an asus a7v8x-mx mobo which showed the running speed of the same ram as 266mhz

thats because DDR means that the speed is actually doubled.
ie PC2700 = 333DDR = 166mhz
PC 3200 = 400 DDR = 200 mhz
and so on.
Dual channel is only for when you have 2 identical ram modules,and you can slightly increase the performance by running them dual channel.

i think thats the problem your describing.
you can always download and install cpuz and check the ram and fsb speeds there.

good luck
