Should have looked at the link i gave you in your other thread

I'm just trying to work out which of the other settings i can try changing to increase performance. Ie: I have no idea whether memory performs better if the CAS Latency is 2 as opposed to 3. Is higher better? That's the question really...
Memory dividers can be set in BIOS.
In BIOS, goto "Advanced" -> "CPU Configuration"
set "Memory Clock" to
200MHz = 1/1
166MHz = 5/6
133MHz = 2/3
You can utilize 3 more dividers using a tool called A64Tweaker.
In A64Tweaker, look for the drop down box named "MEMCLK Frequency", set it to
183MHz = 11/12
150MHz = 3/4
100MHz = 1/2
