@ dentnu, what made you bump your vtt to 250?  I'd keep it at 200 unless you're getting constant BSOD124's.   As well as increasing your pcie freq, try decreasing it back to 100 also.
 
@threedhero, yep I'm already using the cold slow bios.

Nice Q! I bet that was a pleasant surprise.

 
Yea, it was...and prepping for LN2 benching is so quick, in 10 minutes you're ready!

well I tryed what you what you said I am at 191 blck, vcore 1.59xx and VTT 200 also put my pcie freq at 100 so I run the cpu test 1 and 2 and it passed. So I restart the whole complete benchmark but when it gets to cpu test one and about 80000 ops it freezes but to my surprise I press ctl atl del and what do you know it lets me end the process with having to reboot. I must be very close to having it stable but I just can't figure out what setting I need to raise. Any suggestions plz ?

That's fairly typical.  You may need just a little more vcore.  Did you try 1.6v?  Try every vcore setting above 1.59xx.

Thats the thing once I hit vcore 1.6xx its like it goes completely unstable as it gives me a hard lock causing a BSOD reboot almost as soon as cpu test 1 starts. I ill try once more see what happens thanks for the advice

EDIT: Forget what I just said I am still trying to get this to work will post back when its stable and working . .

Turn vdroop off too.

Ok well I tryed every suggestion on here and I still can not get it to be stable on 191 Blk. Its a hit and miss somtimes its stable it sometimes I get BSOD 101 or 124. I went all the way to 166 vcore and 325 vtt and still nothing. So I give up it is just to much of a mission for 50mhz more and I do not think its worth so much effort since I am already on 1.65 vcore there really is no that much more  I can push i. I am very greatful to everyone here that has helped me as I was able to get it stable at 4.7ghz which is 190 blk. Its a pretty  big jump from my 4.5ghz and I always thought it was impossible  to reach anything over 4.5 and with you guys help I was able to do it.
 
Thanks
 
P.S. I was able to lower the Voltage on my 580 from 1138mv to 1125mv as I started to get gray screens. So I was able to get my 840/1880/2200 with a 1125mv  perfectly stable I am going to see if I can reach 850 wish me luck.

Alrighty guys, I can get a TRUE 120 Black for $40 shipped. Should I? 226W TEC would be sandwiched between Apogee GTZ CPU waterblock and it. (Cold side would face CPU block ofc, hot side would be on the TRUE. What kind of temps would that give?

NEVER give up, just take some time to re-group.  Last I recall I didn't bench anything LESS then 300 Vtt.  I noticed the higher I went the more I added to VTT and it worked.  I think at one point I was around 450 and up in the 5GHz, but don't quote me- its been SUCH a long time.  I haven't benched since last MAY!
