Dunno m8, im like u with OCZ, im running the same timings @ 2T. would love to be able to use 1T but i cant see it as its down to the chip as far as i know.
Yeah the other proble is my ram aint 100% matched I have 437 chips for low voltage and 440 chips for higher voltage although I got a set of la off gollum which has the 437 chips as well so I may mix and match see what happens
