Memory frequency and timings confusing me

[Zogger]

I'm currently overclocking my 6300 (below [F7 Bios btw]) and the memory is confusing me a bit.

I'm not sure whether the memory frequency given in the bios is the same as the rated frequency for the memory.
For example with an overclock to 2.25GHz (322x7), with the memory multiplier set to 2.0, the Memory frequency is 644MHz. However if I boot into windows, CPUZ shows half this speed (322) with a 1:1 divider.

If I leave it on auto multiplier the bios gives me 805MHz while CPUZ shows 402.5 with a divider of 4:5. Which one is on the same scale as the 667 rating?

I'm really not sure what I should be setting this to. Everything I see talks about dividers while the bios uses multipliers.
Additionally I don't know what I'm doing with timings, so they are currently set to auto.

Any help with either of these would be appreciated. Thanks

The Bios reports the DDR speed, whereas CPU-Z shows the actual speed.

DDR = Double Data Rate, the memory transfers data on the rise and fall of the clock signal. So basically for every 1mhz of FSB it transfers the equivellant of what old SDRAM did in 2mhz.

805 is the equivelant to the 667 rating.

thanks,
will set it on 1:1 @ 333fsb then for now. Timings were something like 7:5:5:20 with the other one so I'm assuming this will be the better option.
