680i SLI is too expensive? Asus as the solution : P5N32-E SLI PLUS

So far I've discovered that with 1.45v CPU VTT from BIOS (everest shows 1.50v) I GET A BSOD. Upping or lowering the VTT voltage results in a freeze. I also tried lowering the subtimings A LOT, but with no results. 1.7v NB seems to be the lowest possible voltage, any lower and it will just freeze within minutes. Haven't tried any higher than 1.85v to NB, and I'm not sure I even want to

Damnit, I'm so close. Maybe it's the 1.2v HT voltage? It's just an infinite number of possibilities, trying every voltage combination etc.


------------------------------------------

ok, so what I've gathered from numerous sources around the internet, the CPU VTT voltage has actually NOTHING to do with the CPU frequency. It's basically the FSB VTT (what Everest suggests in the first place ).

So, for every FSB there is a certain FSB VTT voltage. When running these kinds of FSB speeds (333+ MHz) the voltage has to be PRECISELY correct. Else, it will just freeze randomly.

Now that I've got the VTT voltage dialed in correctly, I'm still so lost with all the other possibilities. SP-MCP HT frequency, LDT multiplier, 1.2v HT voltage, SB voltage (maybe it has something to do as well?), the DIMM VTT (which I'm thinking of trying next) and so on... sheesh.

What are the FSB VTT voltages for different FSBs?
Do you have a list or table so one can have a look at it to see what VTT voltage is needed at a certain FSB?
