Yep, I managed to get my 1.6A on an IT7 to do 2.4 and 200 fsb on the memory. This was with the core voltage at 1.65v and the memory voltage at 2.7v in the bios.
Initially, I could only get it the samsung 2700 memory to do 184 fsb, but once I changed the settings in the advanced memory menu from SPD to Manual and then changed the individual settings to 2.5/7/3/3 (it was previously 2/6/3/3 at SPD), it worked without any bother at all.
I also kept on burning in the memory using Sandra as I was upping the fsb, which probably helped a bit, but changing the speed settings for the memory was really what made the difference.
Hope this is of use.
