strict timing is fast not fully true .. but of course depends on
endurance your ram, if too tight and you will get instability system and maybe cannot boot. I have a ram with timings 7-7-7-20 and result less than 8-9-8-23 score.
why .? be so... because I oc ram by increase fsb and the ram has a higher clock will be faster. Try
test with a benchmark software MaxxMem and download in : www.maxxpi.net/pages/downloads/maxxmemsup2---preview.php
And you can compare tigh timing and how high result performance...?
And finally you can follow partisipation to contest in Hwboot.org ... Good luck
