to see if you can get a stable system with the voltage setting, if so, and with 2x1GB RAM, you can try lower MCH core and CPU termination voltages,
and then retest your overclock again, i would say MCH core 1.30-1.36v, CPU termination 1.20-1.30v, also try MCH ref. value 0.68v and maybe 0.72v (of VTT 1.20v),
for memory timings, you may want to first try setting Auto, and if you set Turbo, the board's bios will enter SPD's (usually, it will be using timing of the module when running at DDR2-800) timings and this should work ok with a good overclocking ram kit like yours.
i hope this helps.
-----------------
note-- in order to use the ET6's voltage setting value in your BIOS, for example, if you want to try my voltage setting (above),
the easy way is to first set VTT to 1.20v, Vdimm 1.80v,
and then set the other voltage and ref. settings using the value shown in the ET6 and go back to VTT and Vdimm and change the 2 values last.

Thank you pangingIII, awesome help as usuall, much appreciated. 
Sorry for the late response, I have had some Christmas computer time off.
All my RAM sets are okey according to Memtest86+ and since I can run FSB 450 RAM 1200 CAS5 and FSB 500 RAM 1333 CAS5 without error in LinX, Prime95 blend and HCI design Memtest, I reckon thereīs nothing wrong with my RAM, it most be something else.
I remembered when setup FSB 500 RAM 1333 CAS5 I first tried with MCH core 1,40v but no boot, then I tried 1,30v and it boot okey in to Windows.
Well I tried the same with 500 1200 CAS5, start at 1,30, no boot, tried 1,28, no boot and 1,26 and it booted in to Windows.
With P35 and X48 it usually was to low volt if it didnīt boot okey but with this P45 it seems to the other way around, very interresting board this EP45-UD3P.
So with CPU Term 1,28, MCH core 1,22 and MCH ref 63,5% I was running 500 1200 555 15 tRD8 Turbo Stable.
