Yeah but running 4.5 @ 1.6v, updating bios and having to redo OC, is a lot different from a dead CPU.
 
Why don't you ask Falcon about that Gulftown he fried running 2.0V through it?

It was more to the point.. A dead CPU. Is dead. It doesn't boot at all. Whereas I'm now back to 4.0 and climbing. i.e. this isn't a dead CPU.

You might need more vcore than you used to. That is what happened to my old chip after a bios update. All my overclocks needed more vcore. Even after I went back to the original bios. Hope that is not the case with you.

Frequency Control 
CPU Clock Ratio ( 21X )  Why doesn't 22 work?
CPU Host Frequency (Mhz) ( 215 ) 
MCH Strap ( Auto )  Give 1600 a shot
CPU Uncore Frequency (Mhz) ( 3446Mhz { 16X } ) 
CPU Clock Skew ( 0 ps )  500 will not hurt anything
Spread Spectrum ( Disabled ) 
PCIE Frequency (Mhz) ( 109 ) Why? You are not at the insane point of 230+ put to like 102

IOH/ICH I/O Voltage ( 1.650V )  Too high one click for every 2 IOH VCORE CLICKS This is anotherone that really does not seem to help anything.

  Ther you have it my .02.
Notice I made no suggestions for v-core? Thats because give it what ever it needs and your cooling can handle.
  Remember these chips do not like to much voltage as much as they do not like to little.
 

Roger Awall, testing that now. Starting at 190blck though, 1.40Vcore, +100 VTT. Just wanna see how high it gets with these settings.

98 percent of the time....you will have to redo your over clock. just no way around it and the clocks never work the same....until..... you start over...then once it's said and done...it usually either takes a tad bit more or less...and in half the cases...they are about the exact same. but for some odd reason...you have to do them all over to get them back to where they where to begin with.
could have something to do with memory locations from the old to new bios...speculation of course

Interesting, but I saw this on my E758 as well. It's very odd imo.

202x21 stable @ 1.40Vcore, +125VTT
 
Upping vcore to 1.5, and VTT to 200, pushing from here.

bsod @ 1.50Vcore, +250VTT, 208x21.
