Thanks, but the didn't help ... i mean, my setting are with more voltages. VTT is what help stoping the lockups, and 1.36 VTT i just for 455, my goal is 470. I'm now 100%, that it's CPU problem. 6x472 - no problem, 8.5x473 - hard lockups.
A question - after flashing P5E to RF, and 04** RF to 0701 RF i haven't clear CMOS(never cleared it). Could this help or clearing is just after flashing to reset BIOS?
I'm just hopeless now, for 450 i need really low voltages, for 455 i'm rising them and it just keep on locking up ...

Ok try this, forget all the settings you are using right now and start fresh.

Start at 466mhz FSB with 7x multi and PL at 9 on 12:10 divider. Leave CPU GTL on auto, set NB gtl to 0.63x. Start with 1.24v VTT, 1.41-1.45v Vnb, and whatever Vcore you need to be stable and guaranteed error free. 1.2-1.25v I assume would be enough? DRAM Clock Skews to Normal, and advanced/delay if you need to. DRAM Static Read to Enabled, Vsb to 1.075v, Vsb_pll to 1.50v, Vcpu_pll to 1.54v, Vdimm to whatever you need for ~ 1120mhz, DRAM Controller REF to DDR2_REF or -10Mv, others are ok on auto, PCIE frequency to 102-104mhz. AI Clock Twister if you have it set it to moderate.

And start from here. If you don't have all those options don't worry too much, but if I missed some let me know what they are. Also put a 40mm fan on the NB heatsink if you haven't got one already.

And with Vtt, for me sometimes changing a few Mhz FSB above whatever I'm using requires me to add 0.04v - 0.06v Vtt, then I may go up 2-3mhz more and have to drop Vtt back down 0.08-0.1v to get stable and adjust GTLs all over again. Everytime you change Vcore, Vnb or Vtt you have to adjust CPU_GTL, NB_GTL or both respectively.
