    It may also be that because your board has limited adjustments, that you need more Vcore to compensate.

    It's perfectly reasonable to set a BIOS voltage that gives around 1.3625V in windows at idle, rather than limiting yourself to 1.3625 in the BIOS.

    Give these settings a go, and see how you get on. I've written at the side the values you will need to do your own tests on adjusting:

    Thanks Buddie. I do have driving strength option and I have set that to 800 at the moment. I will give a go with the settings you have mentioned and will reply back. Thanks once again. :)

    To clarify CPU ref tuning, to try all possible values between 1.2 and 1.4 CPU term:

    Set 1.2V CPU term
    Set one tick lower CPU ref
    Try 1.2, 1.22, 1.24, 1.26, 1.28, 1.3, 1.32, 1.34, 1.36, 1.38, 1.4 CPU Term
    If no good, set 1.2 and lower another tick of CPU ref
    Repeat 3
    Set another tick down, then up to 3 ticks up, at each change, do step 3.

    This can take a while as it's 66 things to re-boot for all together.

    Does this help reducing VCore? If it does can the CPU Reference be changed with EasyTune to save some reboots?

    I thught starting from stable, and try decreasing VCore untill Prime95 fail, change CPU Reference with EasyTune and start over, then reboot for another CPU Termination, and use the best of them all.
    IMy motherboard hs only 0.1v steps for CPU Termination and 4 options of CPU Reference (default is the highest.)

    I would use the BIOS, not easytune personally. I wouldn't trust easytune as far as I could throw it.

    LOL, and then, can I use it for the vcore? Can't boot for every notch.

    You can, and IMO you should. If you're running a stress test after, the P|C's out of action, so why not re-boot? It only take 40 seconds to boot Windows (for me).

    I finaly have thanks, it seems 1.2/805(default) and 1.3/807ref are the best, well they work ok where other don't. CPU is doing good 3.9GHz@1.280v, can't stress it thogh till the weather cool down.
    EasyTune does act weird. It shows the right CPU Term but the refs are same for all of them, could be just a visual bug.

    Hello Psycho buddie. Hope you can remember me. Well I was busy with life and work so could not try the settings then. However, gave it a try now and the most stablest setting was 1.4 termination voltage and CPU ref of 0.805. I do not have any option to go higher than that. However, I can go lower but it was not stable. After trying for about an hour and so, I set all settings in BIOS as Auto except CPU and RAm voltage and got a stable 400X9 OC with CPU voltage of 1.46875 in BIOS and in Windows ( 1.408 to 1.424). However, even after disabling all energy savings settings I do not know why the voltage jumps like that.

    THANK YOU VERY MUCH FOR YOUR HELP.

    However, now when I restart the system, I am stuck on a blank screen. I have to hit reset and then the system boots fine with 400X9. This happens everytime. Dont know what is going on wrong now. Please advise.. :)
