I just got some F2-9600CL5-2GBTD with the aim of lowering the vNB and they did not dissapoint.

With my old ram i was running a vNB of 1.41 BIOS which was 1.44 real.
Now, running with the 3:4 divider 1133Mhz with AI Clock Twister Lighter PL6 i'm LinX stable with vNB at 1.25 BIOS 1.28 real and i'm getting higher GFlops and memory bandwidth too.

It looks like the timings can be tightened to 5-5-4-13 at 1.80v BIOS (1.87v Real) aswell. I'll post the final settings once they've been tested with HCI memtest and P95+UT2004
