How to set my RAM to 2.5-3-3-6 ?

I have 2 sticks of Corsair 1024 MB 400 MHz CL2 DDR-RAM (CMX1024-3200C2) in my PC.
They are rated 2.5-3-3-6 on AMD Systems.
My BIOS is set to Auto and it sets following parameters:

Memclock index Value (MHz)      400 MHz
CAS# latency (Tcl)              3
Min RAS# active time (Tras)     8T
RAS# to CAS# delay (Trcd)       3T
Row precharge Time (Trp)        3T
Row cycle Time (Trc)            11T
Row refresh cyc Time (Trfc)     13T
Read-to-Write Time (Trwt)       5T
Write Recovery Time (Twr)       3T
1T/2T Memory Timing             2T

I think this is not 2.5-3-3-6.
What do I have change to get my RAM running in 2.5-3-3-6 ?
Also how do I find out if the RAM is running in Dual Channel Mode ?

Someone explain how you get 2.5?
