I'm gussin you must be on a devider for the speed you are asking for. So first off, the mobo NB and FSBT need some overvolting to keep up with the BUS load/stress, and of corse the RAM needs some more vdimm to keep the speed. I used 2.24 for 1152 in my 2nd profile on a 5:6 devider but NB need 1.52v and FSBT to 1.488v. That is with a dual, the quad with the same devider puts even greater load on memory with that devider so more FSBT and NB. My Q6600 on same 480x8 in 4;5 needs 1.55v on NB and 1.505v on FSBT with PLL of 1.712v and of corse CPU at 1.52v
Thr 1:1 with RAM frequency to AUTO and might as well leave strap to auto since ohte quad users are reporting no luck with any other strap then 266 with is defult for this CPU, so AUTO is just fine.
Good luck!
