System Specs:
CORSAIR 8GB DDR3 XMS3 INTEL I5/I7 DOMINATOR 1600MHz (4X2GB) CL8
AMD PHENOM X4 II 965 BE 3.4GHZ 8MB SOCKET AM3 BOX
ASUS M4A89GTD PRO USB3 AM3 890GX ATX
SAPPHIRE RADEON HD5870 Vapor-X 1GB GDDR5 PCI-E DVI / HDMI / DP
Right now it is running all components at standard frequencies. The first thing I want to start with is overclocking the CPU:
CPU CLOCK 3400
Multiplier 17
Bus Speed (FSB) 200
NB Frequency 2000
HT Link 2000
Core Voltage from 1248 to 1260

You should perhaps try to reach 600MHz + on all cores and the IMC + 600MHz / CPU-en, which probably is not unattainable with stable values of voltage and also still have good thermal numbers.
It all plays out a bit if you have adequate cooling. With his own experience on Phenom II processor then most warm by an increase of volts or even just the frequency of IMCen. So the increase of both the fast it can boil down to whether you have approved the cooling or not.
You can see first whether your chip goes far without the volts and see depends on your satisfaction with it. Although I can run 3.8 GHz on stock (have not tried the 3.9 tho, jumped right at 4.00) on stock Vcore and 2.4 GHz at IMC, also stock, 1.15 v (But for the record, this is the a Thuban X6)
Actually it's probably just starting to increase multiplier (since it is unlocked's the easiest way) until you come across instability, then increase the voltage with small steps, and keep an eye on temperatures! Surely not anything definitive since all chips are different. You just have to try it out.

Increased first Multiplier on the CPU to 18 (3600Mhz) and drove the prime 45min without any problems. Now I have increased it to 19 (3800MHz) and set NB Frequency to 2400 MHz. Only these two things I've touched so far. Tests with prime to see if I encounter any problems.
Forgot to tell you that I am running water cooling on the CPU. the fans spin at 600rpm and CPU temp at load is not reaching 50 degrees, Core temperature remains a few degrees below this.
When I increased to 18 in mulitplier and continued CPU to the clock itself at idle, now 19 and increase the CPU-NB keeps the constant of 3800, according to CPUZ. Why?

You may not have turned off AMD C'n'Q and C1E? It should be fully possible and overclock with this. Think "Deneb" C3 plug it in if you are moving beyond 3.8 GHz. Maybe this depends on some of the motherboard as well. 3.8 GHz votes least with what I have been with me earlier.

No, have not turned it off.
CPU temperature rose to 55 degrees at load now, Core remains at 52-53. Ran Prime 1 hour. Stable as that. Set on one chassis fan CPU temperature went down to 46 and Core 49 I think I can go even further
Woops found out that I had run 3800mhz on auto volts. so the CPU voltage up over 1.4 volt and CPU/NB 1.35 volt! Asked this down to 1.36v on the cpu and 1.20 volt on the CPU/NB. Now load surrounding temperatures etc to 5 degrees lower.
What do you think is the max volts on each of the 24/7? Will not degrade the life of the CPU too much riding on the frame 1600 MHz now with 8-8-8-24-41-2T. Should I watch the frame down and either run lower timings?
