RRunner I am almost equal settings too you at 3.552Mhz. FSB 203. I have been using this setting for awhile now and it seems to be my personal best with stable. What voltages are you using in comparison to mine.
X17.5, 203FSB, X12 NB&HT 2432, CPU VDD v 1.450, CPU NB v 1.375, CPU v 1.510, CPU NB v 1.405, CPU PLL v 2.652, Dram v 1.80 (my sticks), NB v 1.30, SB v 1.25

Different memory but I am 9.9.9.24.2T, C1E off, CnQ Auto, SpreadSprectrum ON (I have no stability problem with on), GPU 810/1090. My temps are high 20's idle, up to high 40's under load.

I am trying to compare other results too see if any of my voltages can benefit or keep me stable if even lower. I have had higher temps with lower voltages and less stability?

Thanks.
