I'll try and have a look for the link.It doesnt have to do with the quad not running at 1066FSB(which it does) Here is also the link
" If you go with the Q6600, you don't even need highly OC'able ram, since the quadcore cant reach much further than 3.6Ghz anyways.
Q6600: 9 * 266 = 2.4Ghz, DDR2-533 << STOCK speeds
Q6600: 9 * 333 = 3.0Ghz, DDR2-667 << Nice OC
Q6600: 9 * 400 = 3.6Ghz, DDR2-800 << Great OC
"
I can't remeber where i read it first which explained it nicely
