I was on a older bios and was able to get to 4.2 and it was stable as a rock, now with the newest "77" bios I am only able to get it to boot @ 3.8Ghz, if I even try to go any higher it will not even boot. 3.8Ghz is stable but I want more again.
 
my system is:
 
Mother Board ( EVGA E758-A1 3-Way SLI )                                                        
Bios ( 77 )      Wish I knew what the last one was I would just flash back                                                 
CPU (i7- 920 ) | Stepping (D0) 
CPU Cooler ( Corsair H-50 Push/Pull )  when I ran 4.2Ghz before load temps in the mid 60s 
Memory ( Corsair 6GB DDR3 1600  ) 
PSU ( Corsair TX750W ) 
GPU ( 2x5850s )
OS ( Windows 7 64 Pro) 
 
I took pictures of all my old setting, can post pix needed, and I went into the bios to setup the bios just like it was before because I had it perfect. I see there is a few new things in the BIOS, wondering if anything needs to be changed in my settings.
 
Anyone else with this board and the newest bios that can help?
 
Thanks
Nick
 
PS: have done lots of searching, these are the guides I used over a year ago to get to 4.2Ghz

This is my 1st post (joined a year ago), so you might tell that I am desperate for a fix to my problem.

post 3.8 settings as of now and stable 4.2. what bios did you use prior to the 77 (z2z?)

... Just wish I knew which one I used to run, ...

If this was the first time you have ever flashed your bios, and you were running what the board came with, you can tell what BIOS you had, by looking at the sticker on the clam shell. ( warning it's small and hard to see. ) also if you were a earley board adopter, the first Originaaal BIOS will not be listed under support, as EVGA doesn't list the original BIOS for download,

Also for future referance; see my sig, If you list your BIOS version in your sig, if you ever forget what version you have, all you have to do is post anything to find it, I did not want to replace the small sticker on the clam shell, or go to the trouble of puting one on the side of the case, I found a Sig input a simple soulution, and no one ever has to ask what versionI am running. 

Try to use the 1600 MCH Strap instead of Auto

I will check again but I think it was disable, i noted that as a new item when I did the flash and made sure to disable it, or at least I thought.

He is a screen shot of my system @ 4.2Ghz... the Vreg is getting hot. you can see it is @ 74c right after IBT, idle it is high 60s, and during games it is low 70s.
I was wondering if you guys could recommend a few voltage settings that I could lower to try and get the Vreg to come down a few degrees.
 
Here are my Voltage settings:

EVGA VDroop Control - Without VDroop

CPU VCore - 1.35V 

CPU VTT - +300mV

CPU PLL - Auto

DIMM Voltage - 1.60V

DIMM DQ Vref - +0mV

QPI PLL VCore - 1.350V

IOH VCore - 1.350V

IOH/ICH I/O Voltage 1.600V

ICH VCore - 1.200V

PWM Frequency - 1067 KHz
 
Thanks again

Thanks... Ya I put two 40mm 4k RPM fans on my Vreg.
 
I guess I will just not worry about it then.
 
Or even thinking about reseating the Vreg cooler, I read that helps 

Ya that BIOS rocks, it is solid and have even been able to lower my voltages from my last post and get the Vreg to go down to 72*c on load and still be stable enough to run any load test without failure.
 
I agree with this "Overclocking is useless to me if it is not rock stable. "   ;)
 
I did enough search around and found that that BIOS seemed to be solid for people running my CPU and clocks, so I ran with it and it has worked out great.
