I've confirmed that i'm running 1T cause I can easily switch back and forth wth A64 Tweaker and see my SuperPi results. I'm actually getting .4 faster in 1Million now with 4x512 with all the exact same timings including 1T.

I ran 2 separate instances of Memtest (windows version) for about 30 minutes with no errors....this is weirding me out.

Aren't I supposed to be running 2T? Setup is sk8v, opteron 252 (E4), and 4x512 of corsair cmx512re-3500llpt doing 13x217 2-3-2-6 1T @ 2.7v.
Mine wont even post with 4 sticks and 1T enabled.

Maybe the opterons can? not sure...
run sandra memory bandwidth tests and see what you get...
