    One thing I've noticed in my limited play with tref values so far.

    On my 2X1gig patriot, and my abit av8 board, the values in a64tweaker are done 200mhz/3.9us etc. In that style.

    I've found that the 200mhz/1.95us setting for some reason scores roughly 2000 less than most other values in sandra memory bench. I haven't literally benched them all, but i tested a few values with the refresh at 7.8 and 15.6, as well as some other 1.95 and 3.9 values, and they all netted about 6100-6200 as a sandra score. Yet 200mhz/1.95us scored a mere 4000. It doesn't make much sense.

    I've also found that 100mhz/3.9us seems the best on my patriot. Its one of two to successfully do 32M SP with my current settings, the other one being the above mentioned setup that has less bandwidth.
