You could try 1.17v by increase 4Ghz from 3.4Ghz but use 191x19 with turbo on and see if it stable, if not, move the vcore up one step as a time until it stable.

Over the weekend, I am going to do 4.2 Ghz with a very low vcore possible with 19x200 with intel turbo boost enabled and turbo on. Hopefully under 1.200vcore under bios. Never try that yet myself. Last time I try is 21x200 with a vcore at 1.300v at the bios.

With turbo mode on.
Is this how you have your BIOS set bulldog?
I was always under the impression when you use turbo mode it will just use the 21x multi, so why do you have CPU multi @ 19x and turbo on?
I just tested this out, and when the CPU is loaded it goes straight to 21x, so it wouldn't make any diff if you had the CPU on 20x multi, it will always use 21x when turbo boost is on...
I am going to try some stress testing with this setting anyway to see if it improves stability at all.. though I personally cant see this making any difference tbh... though I could be wrong!!!
EDIT
Also, bulldog, just noticed in your screenshot above, you are only using "standard" setting in IBT which only uses 1024mb of RAM, have you tried running 20 passes using ALL available RAM and 16 threads??
I stopped using IBT and started using LinX instead.. LinX will fully load the processor with only 8 threads..

You have speedstep disabled then i guess?
Mate, I have tested Vcore from stock right up to 1.375v, and QPI/Vtt from stock to 1.4v!!!
I have played around with all other main voltages as well up several notches in the BIOS from stock settings..
It isn't due to the fact that I don't know what I am doing mate, I had my last i7 processor for a few months, and it would boot into Windows @ 4.4GHz with less than 1.3v Vcore, and it was perfectly stable @ 4GHz with 1.264v, but I was having trouble with my RAM not all being detected, that is why I RMA'd that chip, and it was tested and found not faulty, but I was sure it was the processors IMC that wasn't seeing the full 6GB of RAM, so I asked if they would swap the chip anyway, so they sent me this dog as a replacement...
I have spent the last couple of days constantly trying to tweak my BIOS to get a stable 4GHz o/c on this chip, and it just wont go there..
3.8GHz seems to be the limit on this chip...
I was under the impression that all D0 920s could do 4GHz, but the guy from OcUK that I have been chatting with said that there have been a few processors in their current batch that can't do 4GHz...
Really unhappy about the situation tbh.. as I am pretty sure that it was the bracket for my Zalman 9700NT that was causing the RAM problem with the last chip and not the processor.. and now I have been landed with a poor clocking chip!!!
If only I had the bolt thru kit for my TRUE before I RMA'd the last chip, that way I would have known for sure if it was the Zalman bracket...
Here is a CPUZ validation of my last processor @ 4.41GHz..
I couldn't properly stress test the processor at this frequency because the Zalman wasn't able to keep it cool enough, but I recon if I had gotten that processor under water I could have gotten it stable @ 4.4GHz, or 4.2GHz at the very least...
But with air it was perfectly stable @ 4GHz with 1.264v Vcore, and 1.355v QPI/Vtt, and the temps were pretty good as well, idling at 44c, and around 84c when fully loaded, whereas this processor gets really hot, I have it @ 3.8GHz with 1.248v and 1.300v QPI, and the idle temps are @ 50c, and fully loaded they will hit 88c, and that's with a TRUE.. I tested my 2nd TRUE to make sure it wasn't the base of the other one not making a proper contact with the processor, but I got the exact same results...
It isn't going to matter what anyone suggests to me to try and get 4GHz with this dog, it just isn't going to happen for me..
My first chip was OEM, but I got given a full retail chip as my replacement..
As far as overclocking does, there isn't any difference between OEM and Retail chips..
VID for this chip is around 1.1957v or something like that when Turbo is enabled, if I disable turbo boost, it goes down to 1.1865v..
My previous chip had quite a high VID, when turbo was enabled is was 1.2675v I think it was.. but that chip was really good when compared to this dog I have been dumped with!!!

It does seem strange that a low VID cpu won't OC to 4Ghz. are you sure thats where the instability is, memory etc.
DavyBoy, I'm reasonably sure youre temperature limited more than anything else. But as I can't see anywhere that you've posted your load temperatures. it's hard to say for certain.
Into the lower speed bundles ? I doubt theres many out there that wont hit 3.8
Vid does not indicate overclocking potential, it never has done. A low vid tends to correlate with clocking high, but it's in no sense a cause and effect relationship
