A question about overclocking the CPU and RAM?

[cronedog]

I am not looking for a big overclock, don't want to change voltages, and would be happy with a few MHz.

Assumption 1: It is a good idea to run the CPU FSB in a 1:1 ratio with your memory.

Assumption 2: The FSB of the processor is quad pumped, and thus for the 1:1 above, my 1333 default is really 333MHz. (I am rather sure for this one as the 333 times the multiplier of 9 gives the 3.0GHz)

Assumption 3: DDR2 ram is double pumped as thus my DDR2-800 has a real frequency of 400MHz.

Conclusion: If I set this at a 1:1 I should be able to keep my DDR2 at default, this would make my FSB of processor be 400MHz, times the multiplier of 9 would give me a 3.6GHz operating frequency.

My problem is that when I go into the bios, and link the frequency of the ram to the CPU at a 1:1, it reads ram frequency of 1333. My default right now has it at 800. So this readout seems to be operating frequencies.

What is my mistake?

Hi. There are two frequencies that you look at. One is the memory freq, or FSB. The other is the multiplier. Setting the multiplier changes the CPU frequency. Changing the FSB affects the memory speed (and the AGP and maybe the PCIe speed.) Try the multiplier first. If it is stable then increase it a bit more. Do this until you are no longer stable. (I would not increase the voltage as this can affect the chip life.) Then try the FSB one step at a time. Have fun!!
