Ya I might toy around with my timings and voltage at a later date. Right now I need to make my current OC stable . Sorry to highjack the thread OP!!

no problem mate. i use 1.65V for DDR at 800MHz is normal, i mean its not overpowered.
i lowered my CPU/NB voltage to 1.2V i belive its a stock right? but prime95 giving error.

can you say me how do i configure prime95 for right test?
i stresed with intel burner for 5 laps all was OK i achieved 52 Gflops

Ya IBT is good for telling GFlops and highest temps from my experience. The way I was told to run Prime95 was to open it up, select blend, then select custom and then change the maximum memory used and set it to whatever your available ram is. I have 8Gbs so I put 7200 for 98% usage.

Have you tried lowering the cpu-NB volts too 1.3 as that's all I needed to hit 2800mhz. This will also lower your temps to push it a but more.

Sorry, but all cpu has a FSB. FSB is the base cpu speed of 200 on Phenoms. HT is the bandwith. I been working on computers before they came out with 286 cpus. Yes I know I'm a old fart.

Well I ran my 4.2ghz of for 10 hrs that's enough for me to be stable. Try keep ur temps under 62c. I try keep mine around 55c so I have that bit of comfort zone for hot days. If your temps permit bump cpu-NB up to 2800 or 3000 @ 1.3v. And test for 8-10hours on blend.

Can someone explain me with right Voltage settings
there are simly 3 way adjust voltage.
1 is auto - that we dont want to use
2 is manual - that i use now
3 is Offset - that i dont understand

i set up manual for 1.45 or 1.4 but MO never stick with this oltage, at full load it goes under 1.4v to 1.36 (saw in HW monitor). and when i do nothing its goes up to that i set up in BIOS. Why MO lowering voltage at full load?

And how can i use Offset voltage, maybe it will be static? Or there is no problem with varius voltage?

AMD replaced the FSB with the HT REF CLK which is used to generate most of the other bus speeds on the system, RAM, HT link, etc...

So techincally there is no FSB but it still exists in spirit!

And I can beat you 8086!

EDIT - OP, the drop in voltage is called Vdroop and usually happens when your CPU is loaded. It is not really a concern unless you running a high overclock for 24/7. You just need to make sure that when you have OCd and stress tested that you have a stable system with your settings.

Good Luck
