Ok here are my settings as seen in the bios. I can't even boot up without less then 1.42 NB and can't get into windows with less then 1.52, I got as close as the windows logo and scroll thing at the begining at 1.5 but then it crashed.

CPU GTL Voltage Reference (0/2): AUTO\also tried .630
CPU GTL Voltage Reference (1/3): AUTO\also tried .670
CPU PLL Voltage: 1.54 works best so far\also tried 1.56 and 1.58
FSB Termination Voltage: 1.26 don't really know what this does, seems to work best on auto.
DRAM Voltage: 2.10
NB Voltage: 1.52 boots me into windows then crashes, memory error. Will boot with less but not into windows.
NB GTL Reference: AUTO\also tried .630

See if those will make a difference.

Ok I tried those settings as well and still nothing, getting errors using Vistas mem check. I did try something else though and found interesting results. I went back to my old settings I used with an E6320 which I had hummin along @ 3.22 Ghz till recently, I used exactly the same MB settings and just changed the Cpu Voltage and NB V which btw is now at 1.26 at 458 fsb, so there's something else causing me to fail at 550?? I don't know if this helps, my MB Rev is 1.03G and bios currently used is 1702, I can't remeber if it's the modded one any more. I would really like to get the higher fsb, but these settings seem to be working ok right now. If anyone has any more suggestions on how I can get a higher fsb I would greatly appreciate it, my ram can't do much more then 1100 mhz though.
