This could be a long description of the problem but I don't want to put you off so I'll try and make it to the point so please read on if you have used this board or you are very familier with the various voltages and settings used when OC'ing i7's and hopefully you will be able to help.
Had an Asus P6X58D-E, 3x2 gig Corsair XMS3, i7 920 DO, Ven-X Black, OCZ 700ModX (Corsair TX on the way)
CPU easily hit 4ghz, 200x20 or 190x21, CPU and Uncore/VTT were @1.25v, DRAM 1.65v, everything else defaults, ran all day and night.
Until it blew up.
Picked up a DFI X58 T3eH6, lowered the DRAM and CPU multipliers and it cruised up to 200+ with no issues, all voltages default.
So then I started bumping up the multiplier, 200x19, 200x20, all ok, cpu @1.25v.
Soon as I bump up the DRAM and Uncore x8 / x16, it doesn't like it, blue screens and restarts, its ok up to 200x18=3.6ghz but nothing above.
Tried 180x21 / 190x21, ok if you keep the DRAM / Uncore at x6 / x12 but not x8 / x16.
So I tried DRAM increase and VTT voltage increases after reading every guide known to man and all the different IOH, PLL suggestions but NO. [:fisshy:2]
I could list all the different settings I have tried but that would be too much so I'll leave it now and wait for questions and suggestions.
The 2 main areas I'm not sure about are the VRMAX and PPM, all power saving settings are OFF.
