AMD Phenom II X4 960T Black Edition o/c

[agros]

Let me remind u boys that this thread is about 960T...

[agros]

So a little word to say that my 960T has been sold and that the buyer is very satisfied... i'm satisfied too as regards my brand new 1055T 95w edition... i've gently overclocked it: 14x250 @ 1,375v turbocore off and cool and quiet on auto... All is wonderful and this famous cpu at least drops automatically its voltage in comparison of my last 960T : from 1,375v to 1,13v --> what a big happiness !!  

I wish I could get a 1055 in 95W too, but its not available in my country.

What's more energy eater, a cpu of 125W at 1.1V or a cpu of 95W at 1.3V ?

[DarkstaR]

Yes what a pity that this product isn't available in Greece... why not buying it through a french e-seller ? Just require yourself about the ship cost... As regards the power consumption of what you said i don't know... i would say that both are equal..ask directly to Dark Mantis if he should know...
Otherwise in the case you would really buy it just pay attention as my version (95W) contains these 2 capital letters: HDT55TWF whereas the standard version (125W) contains those 2 letters which allows to distinguish it: HDT55TFB

Buy from outside? And what about the guarranty?... How shall I change it if its/will be broken?

Is 1055 easy to o/c as 960T can? wei score? temp?

Hi,
first of all I wanna thanks to Krisbee for an excelent guide how to "normalize" power managenemt of this CPU. It seems AMD just sux hard with their CnQ. With Krisbee's posts and K10stat utility I was able to cut down voltages as follows....

P0 - 3400 Mhz 1,225V (1,45V default)
P1 - 3000 Mhz 1,125V (1,3V default)
P3 - 1600 Mhz 0,97V (1,3V default)
P4 - 800 Mhz 0,784V! (1,3V default)

CPU NB voltage at all states stable at 2000Mhz,  1,0V

BTW I was able to unlock it to 6x, but till I will really need its power I locked it back to 4 cores.

With default voltage settings my Katana 3 was barely able to cool CPU under 40°C in idle state (1800 rpm, cca 2/3 of max)
With lowered voltages I never crossed 40°C at 1200 rpm after 1/2 hour prime testing... just awesome
Idle CPU temps are under 27°C with just 600 rpm B-)


my rig:

ma-ga770-ud3 rev 2
Phenom 960t at 3 Ghz (3,4 turbo), Katana 3 cooler
kingstone hyperX overclocked 1066 Mhz (1,9V)
ati 3650 passive
some Hdds, etc...
CnQ enabled, TurboC enabled,  DDR2 set manual 1,9V, all other settings are at AUTO

just 1 note more, any other voltage settings in BIOS than AUTO (exept DDR2) resulted after win boot+ K10stat to BSOD....

Is this scale auto?... I mean, will your cpu auto drop to 800MHz/0.7V when idle?

[japuaa]

yep, its auto, auto-idling at 800 Mhz/0,7V, no other customising is necesary, just set P- states in K10stat, thats all

BTW just read this arcitcle http://www.tomshardware.com/reviews/processor-power-management,2453-6.html
they cut down phenom 945 idle voltage at 0,6V ! will try it on 960T this evening

Locked cpus are often more difficult to overclock because the user has to raise the htt only in comparison with the unlocked models (black edition) which can be o/ced with multi and htt of course...mine is now gently overclocked at 14x250 @ 1,375v turbo core off and cnq on... but my big satisfaction is that my brand new 1055T auto drops its voltage in idle mode at 1,13v (less good than deneb core such as 955 or 965 c3 which can lower to 0,85v).
Follow the very good advise from japuaa with his k10stat software and try it

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?
If yes, I ll give it a try too...

Come on... we talk for this specific cpu. You had 960T, so u already know how easily is to o/c it. You can get 4.0Ghz with a small core raise and nothing else.
960T is also black edition.
So u drop to 1.13 but out friend japuaa claims he drops to 0.78

[japuaa]

Its just like u wrote ;-)

1) u HAVE TO set all voltage settings in Bios to auto/normal (exept RAM voltages)
2) CnQ auto, TBC auto.....
3) find out the lowest voltage settings in K10stat for each state

as CnQ lowers/raises clocks u can observe voltage reduces/raises too - as u set 'em in K10stat
u can test voltages in K10stat without need of clearing CMOS, becasuse K10stat stats are not saved in BIOS, so when ur rig goes BSOD u can just restart and custumize voltage again
there is 1 EXEPTION - when I lower P0 state (3400Mhz) below 1,225V, my rig wont even restart, I have to clear CMOS all the times I tried lower P0 voltage as specified higher

yesterday I managed to obtain these stable results

          CPU          CPUNB
P0 - 1,225V          1,05V
P1 - 1,125V          1,025V
P2 - 1,025V             1V
P3 - 0,86V            0,975V
P4 - 0,68V              0,95V

tested only few times in Sisoft Sandra CPU power management benchmark which IMHO tests all P-states at all possible combinations...

[japuaa]

any news Argos?

[agros]

Ok, I downloaded the K10Stat091 setup(118kb), I unzipped it and I run the K10STAT.exe and I get this window



Now what exactly should I do in order to have auto undervolting below 1V?
My voltage settings are auto. C&q is auto(on). What is tbc?

[japuaa]

choose P-state bookmark
u will see 5 P-states
set voltages as I posted above, but on firts try u should increase my voltages by 0,125 for sure, for example like this:

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

BUT first of all be ready for, BSODs, maybe u will have to clear CMOS, etc....

IF this config will be stable (after few benchmarks, prime95, AOD stability test etc...), try lovering voltages by 0,125V - 1 BY 1, not all together! and test them again.. and again... and again..

find out the lowest voltages for all speeds, they could differ from my config (different chip, different cooling etc), and be sure to run K10stas at startup after all....

My border voltages are:
P0 - 1,225
P1 - 1,125
P2 - 1
P3 - 0,86
P4 - 0,68

In windows I can go even lower, by 0,25V, I also ran few benchmarks at these settings, they  are stable in Windows,  BUT computer wont restart at all! So Iam using voltages as I posted above, stable, no problems.

 TBC= turbocore technology,in K10stat it has P0 state

choose P-state bookmark
u will see 5 P-states

In the P-state tab, there are 4 states, not 5. What do you mean 'bookmark'? There are also 5 profiles to choose in the profile box.

BUT first of all be ready for, BSODs, maybe u will have to clear CMOS, etc

Before the BSODs and the effort to catch the limits, we should first check if this works. Just a simple safe adjustment to see voltage goes below 1.35...
Anyway, I set it as u said
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
and I press apply, then ok. A sudden restart took place. After restart I re-open K10stat but I didnt see the settings I had made.

[japuaa]

bookmark is a wrong word.. I should said P-stat tab.... sorry

U see only 4 P-states? thats wierd, Ive got 5...
p0-3,4Ghz
p1-3Ghz
p2-2,3Ghz
p3-1,6Ghz
p4- 0,8Ghz

dunno whats wrong, maybe... do u have the latest version of K10stat? 1.54? do u have TBC enabled in bios? I have Win XP, u have Win7, maybe theres problem... realy dunno, Iam afarid u have to use "experiment-failure" aproach....  try default voltages and lower them just slightly by lets say 0,0125 and try to find out whats the lowest stable voltage for ur CPU...

and reseting settings in K10stat after crash, Bsod, etc is good for u, because in case that wrong setting remained, ur computer wont start/restart and then u have to clear CMOS after each failure

here is some guide for K10stat, maybe it will help u
