faster / tighter

so

can anyonew give me the laymans overview on ddr3 ram timings and speeds please? Is slower speed with tighter timings better than the reverse or is the sweet spot to be had with a balance of the two? Where should that balance be?

I've been messing with OC my RAM now i've got my head round i7 OC. I have ocz reaper 1866 rateed at 9-9-9-21 iirc. At current settings (180x21) i've got the ram running at 1444 odd. I've tightened the timings using stock volts down to 7-7-7-20 but strangely IBT runs are slower and the GFlops is lower the tighter I get - the opposite to whjat I expected. Each time I tighteened the ram 9 to 8 to 7 I tested stability using ibt and noted the speeds and each time the runs got slower.

Am I missing something obvious here?

thanks, slackening the timing back to stock and going for highest stable clock to see where that goes. After that will stock sppeds and timings and see if I can drop much voltage.

It might be me but the system 'seems' to boot quicker relative to the tighter timed ram (when it's stable that is).

Thanks for the link, will peruse it later.

Thanks Jon, have given up for now, P08 bios is a load of carp. y ram has a jedec profile at 6-6-6- somrthing at 1200mhz or thereabouts so 1333 odd should be within reach. Interesting that the lower latency wins through just like ddr2 and the rest.
