I'm going to get an AMD X2 5600+ with 2Gb RAM (preferably 667MHz due to the price). Following THG's latest CPU article showing the memory timing on AMD X2s I wanted to run this by you all, to see if I've understood the implications correctly.
Is this logic correct for at 2800MHz CPU?
800MHz RAM runs at 800MHz (as memory divider = 7.0)
667MHz RAM runs at 622MHz (as memory divider = 8.4, so system uses 9.0)
so the slower 667MHz RAM actually runs slower the 667MHz performance rating suggests
slightly overclocking 667MHz RAM to 700MHz+ runs it at 700MHz (as memory divider = 8.0), so significantly closing the gap for a minimal RAM overclock and risk. Further RAM overclocks will give no advantage as the divider won't change down to 7 until 800MHz.
is this correct?
is the difference worthwhile?
thanks
