AMD Phenom II X4 960T Black Edition o/c

Ok, I read carefully that link. First 2 pages talk about description of this application and the rest is how to launch with windows, how to command line etc.
But in fact, I cant understand how this thing works

I followed your instuctions and put on

P0 - 3,4 Ghz  CPU 1,27V CPUNB 1,05V
P1 - 3 Ghz  CPU 1,15V CPUNB 1,025V
P2 - 2,3 Ghz CPU 1,025V CPUNB 1V
P3 - 1,6Ghz CPU 0,88V  CPUNB 0,975V

There was indeed an auto voltage lowering but in a couple of minutes my screen became unclickable. The second time I had a BSOD after one minute...

Are there any minimum safe settings?

Still.... its wierd u have only 4 P-states....

Voltages I posted, are border for my CPU chip, maybe Ive got better sample then u have and ur CPU cannot handle such low voltages...

Ok lets try:

3,4Ghz - 1,3V
3Ghz   - 1,2V
2,3Ghz - 1,1V
1,6Ghz - 1V

and do not mess with CPU(NB) voltage, leave it on default (1,15V) or just sligtly undervoltaged (1,1V etc.)
These must be stable (in case u have locked 5. and 6. core), and if these setting will be stable, try to lower volatges till the first sings of instability occurs...

Could u make a screenshot of ur K10stat "P-state" tab and "Info" tab? When ur computer is idling, what P state shows K10stat info tab? 1,6Ghz or 800 Mhz? Because Iam afraid ur lowest P-state (800Mhz) will bee still set on default voltage (1,3V) = no power savings in idle state....

[agros]

Maybe I have 4 states because I have 4 cores.

I tried what u suggest
3,4Ghz - 1,3V
3Ghz   - 1,2V
2,3Ghz - 1,1V
1,6Ghz - 1V
and no bsod but the difference was infinitesimal. I checked it for some minutes and I had 1.344V at the 99% of the time.
How much of the time do u have 0,8V when your pc does nothing?...

And here is the screenshot of p-state tab(screenshot of the info tab already exists in previous page of this thread). Do u see something?

[japuaa]

when idling I have 99% of time 0.7V at 800 Mhz

ur K10stat window should look like this...

or
http://blogimg.goo.ne.jp/user_image/4e/a3/5dce171804b37cf3983b9de5613a0a73.jpg

if u have CnQ enabled in Bios and instaled CNQ drivers in Windos,CnQ automaticaly raises/lowers clocks of ur CPU from 800Mhz to 3,4Ghz,
BUT
I think ur problem is that u do not have set voltage for ur lowest P-state = 800Mhz (because u dont have it in k10stat window).... so as u set voltages for all P-atates exept the lowest ONE (800Mhz) ur CPU  at 800Mhz is still using default voltage = 1,3V...

Really I dont know why u have only 4 P-states,  every1 with 960T (exept u) have 5 P-states, so I ask again: Do u have the LATEST version of K10stat utility?

[agros]

Well...

I used version 0.91 and that was not the latest one.
I found a newer version, 154 from August 2011, found here--> http://sites.google.com/site/k10stat/.

As u see in the image



Theres a small difference with the image u gave(http://blogimg.goo.ne.jp/user_image/4e/a3/5dce171804b37cf3983b9de5613a0a73.jpg), as u see the bar of 'autos' in your image is in upper position and so is the 'boost'.
I unticked the 'boost' box, too. The 'NumCore' is 0-3, is this strange?
Also note that, in both images, first line is B0, then it is PO, P1 etc.

I gave your first numbers
P0 - 3,4 Ghz CPU 1,27V CPUNB 1,05V
P1 - 3 Ghz CPU 1,15V CPUNB 1,025V
P2 - 2,3 Ghz CPU 1,025V CPUNB 1V
P3 - 1,6Ghz CPU 0,88V CPUNB 0,975V
P4 - 0,8 Ghz CPU 0,7V CPUNB 0,975V

and after a couple of seconds a bsod came. Then I gave your seconds numbers
3,4Ghz - 1,3V - 1,15
3Ghz   - 1,2V - 1,15
2,3Ghz - 1,1V - 1,15
1,6Ghz - 1V - 1,15
0,8Ghz - 0,9V - 1,15

and yes!... Works. I m all the time at 0.9V  

Now a question. Why do I put at 3,4-->1.3V and at 3,0-->1.2V, since the maximums are 3,4-->1.47 and 3,0-->1.35 ? Maybe this means that I wont be able to get the highest volts when/if it will be necessary? I mean, my numbers will be from 0.90V to 1.30V only?

[japuaa]

dont have much time, just in short

960T is drastically overvoltaged from factory....
lower voltages on stock clocks= lower power consumtion on stock clocks
u dont need to burn CPU in idle (800Mhz) at 1,3V... because it will work only only at 0,9V (even lower when u pimp it)
according to some articles mentioned above, u can lower power consumtion by lets say 30W in load and 10W in idle.... besides power consumtion, ur CPU temp will be lower and ur CPU service life would be longer....
yep ur numbers after K10starts will be only from 0,9 to 1,3V - that why we did all of this

[agros]

But then we undervolting our cpu. This is NOT what we want.  Our cpu should be able to get 1.35 (or 1.47 when turbo boost), not only 1.30...

What do u mean "960T is drastically overvoltaged from factory"? All cpu s have some factory defaults.

I asked u "So u start this cpu with its default values(3.0GHz - 1.35V) and then goes auto-idling to 800MHz/0.78V? And if u put on a heavy application, it will go to 3.0GHz - 1.50V? and u answered me "Its just like u wrote", remember?  

[japuaa]

its question of preferences.... I want to have maximum power efficiency and lowest temeratures, so I undervolted my CPU as low as possible (but still with default clocks 800-3400Mhz), against factory default voltage  I lowered power consumtion by 30-40watts in load and even more if idling (because power consumtion is significantly higher if u run CPU 800Mhz at 1,3V against 800Mhz at 0,7V)

If u wanna oveclock ur CPU u just can, just set the highest P-state on max (1,45V) and oveclock it (I saw 4Ghz at 1,45V with 960T)... and u can boil eggs on ur CPU..... its ur choice, but not mine ;-)

BTW ur from Greece, how does ur fanless cooling manages hot summer days?

[agros]

Seems u do not understand me
We dont talk about o/c.
In my previous post I mentioned to you the higher limit, not the lower. If cpu can only go up to 1.30V and not up to 1.35 or 1.47V then this is no good. We want a scale between 0.80V - 1.35V (or 1.47 if turbo boost), is this possible or not?

[japuaa]

yep it is possible... u can scale voltages as u like (0,8V-1,45), or even lower or higher - the only limit is stability ....but, I dont know why u should when ur CPU runs good at lower voltages 

[agros]

Because we can't get 3GHz with 0.8V...

Its really simple but seems u can't understand it--> The point is to get the maximum capacity of our cpu WHEN is necessary. Not all the time. Most of the time will be 0.8V, yes. But when I need all the power I must have it, 1.35V (or 1.47 if turbo boost).

So, how should I set K10stat in order to have the right scale (0.80-1.35/1.47) ?

[japuaa]

ohhh man....
dont u see it i K10stat? it works as u said... or... it should work as u said....
thats THE point, why we did this... to save enegry at 800Mhz/0,8V and to have a stable rig in game at at 3Ghz/1,3V
thats why we set different voltages in alll P-states...
maybe, dont u have some other power saving or oc`ing program instaled? there could be some conflicts between these and K10stat....

[agros]

Seems you forget all the time what we discuss about, plz try to be concentrated. You gave me values for 0.90-1.30V. Thats not what we want for the highest limit. Can u give me values for 0.90-1.35/1.47?

Conflicts and o/c is another story, dont mix them.

[japuaa]

nope, i did not forget...
every single CPU has its own limits, so u have to figure out ur CPU limits (lowest/highest clocks/voltages) at ur own... cant help u with that

everything I can gave u is lowest clock/voltages for my CPU, but as u said before these are unstable for ur CPU...

[agros]

The highest limit is specific---> 1.35/1.47
We dont worry about that. So u must not aim for 1.30 only.
The lowest limit is our point.

What exactly I said its unstable? I m afraid u forget again.
