[HELP OC] Phenom II x4 955 BE @ 3.8 Ghz stable.

[capirex]

Hello guys and thx in advance for helping me. Now one week i need to stabilizing my OC but not really good.. I need your help mates

Ok let's go for my spec :

-Phenom II x4 955 BE (want 3.8 Ghz stable!)

-Asus M4A88TM USB3

-Cpu cooler : corsair H60

Some screen of my BIOS

And now my oc spec in the BIOS :

Cool n quiet = disabled
C1E support = disabled
Cpu overclocking = manual
Cpu/HT reference clock = 200
Pcie clock = 100
frequency multiplier = x19
CPU/NB frequency = x11
CPu over voltage = 1.375000
VDDNB = 1,2
Loadline calibration = 19.35 %
HT link speed = 2000
HT link width = auto
HT over voltage = 1.2V
Chipset over voltage = 1.1V
Memory Clock Value : 1333 Mhz
Memory OverVoltage : 1.50000

Loadline calibration is in % and i had test a lot of them without good result...

I really need help plz some Pro of phenom II x4 here?

THXXXXXXXXX in advance guys ))

post all tabs of cpu z..
as this will tell what to set mem at..
auto is not always good

Ok sorry bro, i forgot to post that cpu-z screen.
DOne now

i use 1.4volts on my 965 but its under water no LLC

 

[boucher91]

what are your temps under load when running prime95 blend?
hardwaremonitor is the one id like to see

 

[capirex]

Ok i run prime95 blend my temp don' go above 55°

 

[boucher91]

first i would set all the main mem settings. may have to give a slight bump in volts to mem..
next just keep adding cpu volts til stable..
ur about at the temp limit where youll lose stability..

What is the make and model of your case and tell us about the size, number and direction of flow of the fans. Your temps look high for that CPU on a water cooling loop with a relatively low vcore and I'm wondering if you have adequate interior ventilation.

Hey guys thx for answering me. Today i made a prime95 test duting 6 hours. No error but my temp go up to 57°. My case have (i think) a good ventilation.
case = In win dragon slayer
2 fans in front for put in the air
1 fan back for put off the air.
1 top for H60 for put in the air
My case is medium size (micro-atx)

According to New Egg's summary of the case fans, here is what it has:

Cooling System

80mm Fans
1 x 80mm HDD fan

90mm Fans
1 x 90mm rear fan

140mm Fans
1 x 140mm top fan

Did you add a fan in the front? 80mm fans don't move much air and the fan in the back is only 90mm. Not a lot of ventilation there. Try taking the side panel of the case off and set a household fan to blow into the open case onto the motherboard. Then check temps again.

I hate to be that guy, but..

Have you considered using a little FSB OC along with that multi? My 955 C2 wouldn't go past 3.60 without me using the FSB-- I got it to 3.85 with a combination.. And that was a C2. You should definitly not have too much trouble getting this up there.. Sadly I'm not too privy with the C3 version of this part

Looks like you're right on the edge of your thermal threshold, but people are already addressing that. If I think of some more constructive input I'll definitly swing by this thread again

 

[capirex]

yes i add a new 180 fan in front. Really my case have some good ventilation ( i change all the fan in the case with all noctua fans). Maybe i can change the thermic paste of the original corsair H60.
And about the mem? What can i do? can help for that?
My mem are 4 x 2 Gb corsair xms3 CM3X2G1333C9 at 9-9-9-24 @666Mhz
And for the other parameter? looks good? Need to up the vcore?

 

[boucher91]

when its stable do not add more vcore as this will cause higher temps..
the top fan on ur case should be exhausting(blowing out of the case).
heat rises....
i have no idea what paste comes with a h60 but is may help to use better paste...

With the Gigabyte GA-MA785GM-US2H (older than OP's board) I can do 3.8GHz with everything stock except the multiplier, CIE and CnQ are still turned on and the VCore voltatge is 1.4. Don't mess with the core unlocking and keep core turbo turned off.

I'm not at home and I took along my old system, X4 955 C3 at 3.8GHz (x19) with a Coolermaster Hyper TX3, 4GB DDR2 800, stock NB and HTlink, CIE and CoolnQuiet still turned on.

you need more volts, its safe to run up to 1.5v 24/7.
but your cooling really doesnt look like it can handle the extra voltage. the h60 really isnt that good of a cooler

CPUs of the same make and model do not all run on the same stock voltage from the factory. If you buy 5 different PII X4 955 C3 CPUs at different times you will find that the default factory stock voltage will not be set the same on them. It may range from 1.325, for example, all the way to 1.4. It depends on the purity of the particular batch of silicone and other fab process variables at the time and place of manufacture. Therefor giving someone else your numbers to punch in to their bios will likely not give the same results.

The Deneb core CPUs do not utilize turbo core technology. That didn't come along until the Thubans.
