What is the vcore set at in the bios?
The VCORE is set at 1.375. How the BIOS works is, it sets a VCORE for the CPU (in my case it was 1.44v) and you can then modify it with the "CPU VID Special Addition" which lets you tweak the vcore in small amounts. I modified it when I first installed the CPU since I felt 1.44 was a little too high for stock and haven't touched it since.
That bios really does sound complicated and awkward for no real reason anyway im sure if you set it at 1.4 you will be able to get 4Ghz it seems like a pretty decent chip. Personally I would go for it but I just enjoy clocking for the sake of it and don't have any real need for the processing power. Also what are your temps under prime like compared to ibt? I don't really worry too much about ibt as it puts an ungodly amount of stress on a cpu that it will never come close to in normal usage.

The BIOS is very awkward. It's the most stable one I have ever owned, though.
I'm the same - my goal with this was one of learning. I'm eager to push it a little more though because it seems it's taken nothing to get to 3.8ghz.
About 1-2c difference between prime and IBT. I'm gonna try 3.9ghz later today and see what that gets me.
Ok, so, 3.9ghz is stable under IBT at 1.4v, but I can't get 4ghz stable even with 1.425v. I think I must be hitting the so called "heat wall" since I'm getting to 55c more or less at 4ghz.
Looking back over my results, the CPU-NB increase increased the temperatures by basically nothing so it seems worth it to put that back on. I'll do that later on and post back if I run into any problems. Thanks a lot for the help, everyone!

I have this board and it's rock solid, you can throw anything at it
Try your NB at 2600, I think that I was using HEX code 17 (1.26v)
You'll have to increase your CPUv to get it stable at 4Ghz, up to 1.5v is ok for phenom if you have a good heatsink and fan to keep it cool
Your memory should be at 533mhz not 400 for optimal performance, try the 1066 setting in your bios, you can also increase your ram frequency by increasing the bus speed with AOD to say around 215 and keeping your multiplier at X18

Hex code 17 is 1.26v, yep. Unfortunately I don't think my cooling can handle 1.5v. Also my memory is ddr2 800 unfortunately and won't handle 1066mhz 
Having trouble getting the NB stable. I tried 12x multiplier at 1.25v and I got a core drop out during 12 hours prime. Not sure if that's specifically the NB or if the CPU needs more voltage. It did 12 hours or prime without a problem at these settings with stock CPU-NB though.
