Could someone explain this 1:1 thing please? Thanks in advance.

It runs at 1:1 with your bus speed instead of faster or slower. Example I run at 1:2 so I get 533 mhz where as 1:1 is 133(bus)x2=266 mhz

Well, Im quite new to Oc myself but my understanding is:

In simple terms, 1:1 refers to the ratio that whatever your CPU speed is then your RAM speed will also be matched. For example, AMD CPUs are multiplier locked so the simplest way of overclocking is to change the FSB (Front Side Bus) which is known as HTT for AMD.
The HTT is usually set at 200 by default but if you change this to say 220 then it affects everything in your system at the same ratio. So ram set at 200 (DDR400) will also go up to 220 (becoming DDR440 or running at 440mhz).
Some ram do not overclock well and overclocking the CPU a lot will also affect the ram speed a lot, therefore you can move from 200mhz to a lower speed. This will alter the ratio though.

You can change it to:
166mhz (6:5) For every 100mhz of CPU the ram will only be 83mhz
133mhz (3:2) For every 100mhz of the CPU the ram will run at 33mhz.

I think this is correct, well this is my understanding so I hope I can be corrected if Im wrong.
