Overclocking the memory

Hey,

I want to overclock my memory, but I have a question about it. I've noticed that when you overclock your CL then the speed of the memory will automatically jump to a lower speed. Is this correct?
 
I'm not sure what you mean. You want a low CL, you dont want your CL to be high. When you raise or lower the CL (timings), it should not effect the memory speed at all.

And what a lot of people don't seem to understand is, having high clocked memory isn't always what you want. The best option is to have the memory run in a 1:1 ratio with the FSB, and you want low timings.

Yes, I mean to lower my CL in other words, overclock I guess?
What I mean is that if I open Everest then there you will see this:

What I understand of this picture is that if you lower your CL your speed will be also a bit lower.

And OMEGA what do you mean by 1:1 ratio? Can you be more specific? Because this whole memory overclocking is not really my specialty

Thanks.
 
What you are looking at is the rated timings at the memory speed. Now to answer your question, the lower the timings, the less time it will take to read and write, giving better performance. So at 333mhz, the memory is designed to run at 5-5-5-15 timings. At a lower speed, you can lower the timings on the ram. For example at 266 mhz the ram will be able to run at 4-4-4-12. Also, the numbers in everest, tell you the rated speeds. You might be able to run lower timings than are stated in Everest at the default voltage or possibly with a slight raise in voltage. But beware that you might run into errors running the ram at timings it was not designed to run at (or not, but there will be a limit).
 
what processor do you have and fsb setting are you using? If your fsb is not above 266, use the 4-4-4-12 settings! I need more info here!

And which is better for higher performance, 333 MHZ at 5-5-5-15 or 266 MHZ at 4-4-4-12?

Thanks.

Those are settings from the factory, you can manually change them yourself for improved performance. For instance, my RAM is running at 475MHz 5-5-5-18 @ 2.15V.
