Thanks...had a lot of cakes and fizzy drinks today....

Aahh, so probably the IGP is working the Core Logic chip extra hard on your case....

Manually set the voltages let you understand more on how varying voltages react during overclocking and the amount of heat raising through each and every hundreds of mhz you bring up to the CPU...

Try and get the stock values for each components such as CPU, CPU-NB, Ram, Chipset, HTT and PCIE and then set them manually and start raising from 200 with ram running slower i.e: 1066 or 800mhz... drop down the CPU-NB also...

The back fan not functioning bcs havent bought the adaptor to connect to power supply

Added on July 12, 2010, 1:42 amantonio, that's what i did to check the Max FSB
Increase the FSB and decrease the multiplier so that the frequency close to 2800MHz
CPU-NB, HTT and Ram all configured so that close to stock value
Voltage vice i let it at stock value as I think adjustment wont be needed as all the values are close to stock value
Ram wise I didnt start with lower value, i let it close to 1333Mhz

System is stable until the FSB reaches 250Mhz, then errors occured when tested with prime 95

Naise HAF922 case u got there

Hmmm getting a better cooler helps eliminate the heat issue for ur cpu, software temp readings sometimes are not really accurate, like bro antonio said u need add a lil more as heat headroom also
I really know that a 1055T can be push higher than what u getting coz i tested my friend's cpu just a few weeks ago.. To get to ur speed cpu volt around 1.3v is also enuff
U may need to put some heatsinks on ur pwm's also just incase like what i did with my old Gigabyte MA770T-UD3P:

mind to let me know how to put the heatsinks?? where to buy?
Noob question, what is pwm???
Any good cooler recommend??

wuts the safe NB volt(not CPU-NB volt) on air cooling on a air cooled system?

Do i need to put heat sink to my PWM too? and i also notice the NB is quite hot....can't lay my fingure for more then 5sec

my best OC so far, come2 comments, any bad or good or room of improvement( gonna try 4Gghz later 2nite, still can stabilize it , heard a legend u can increase the NB(not CPU NB) volt abit, but duno how much, takut anything happen, all i noe stock is at 1.1v, till now still getting blue screens...anyway check this oc out guys!

- Windows 7 Ultimate 64-bit
- Phenom II 965 BE
- CPU stepping : CACAC AC 09456PMW
- Revision : RB-C3
- Max CPU clock speed : 3917.7 MHz (200.9*19.5)
- CPU voltage : 1.472 V
- Northbridge clock : 2800.0 MHz MHz @ 1.40 V
- HTT link speed : 2009.1 MHz
- HTT link voltage : stock voltage(shud be at 1.1v)
- Motherboard used : GIGABYTE 870A-UD3
- Type of cooling : Tuniq Tower 120 Extreme(Air)

Try looking for these small heatsinks to put on the mosfet's of ur pwm's, extreme oc will put quite a load on the mosfets and some cases it can go kaput also



This are the place where mobo pwm's are located:
PWM's without heatsinks on usually cheap or mainstream mobo's


PWM's with heatsinks on modrange mobo's


If i'm not mistaken u should keep ur cpu-nb volt below 1.13v or is it 1.3v
I never played much with the NB volt becoz to me it has no much relevance in oc'ing a cpu..

Some mobo's do not come with proper heatsinks on the mosfets of its pwm circuitry, used a few giga mobo almost all of their value mobo does not come with it
If i'm not mistaken Gigabyte 870A-UD3 & 880G-UD2H does not come with also right?
Last time i used Giga MA770T-UD3P i had to put sinks on my pwm's if not in some cases i could hear it screaming

Hmmmm from my experience i don't see any difference in my oc when pumping more NB volt, to me it's better u play2 with the CPU-NB volt bcoz it's for the cpu IMC..
What i experience is that by playing the CPU-NB volt u can actually decrease the amount of volt u need to pump into ur cpu volt..

can anyone teach me how to overclocking amd 7750BE 2.7ghzto go until 3.1ghz???it is posible to do that?? any side effect??

now cloudwan speaks like a true OCer..

Added on July 12, 2010, 11:14 ami think u just need to pump the fsb..
stock voltage also sufficient i guess..

@antonio
ur birthday yesterday eh?
tanjobi omedeto..kekekek.

@cloudwan.. ur old gigabyte is my new gigabyte lol..

done stressing the ram pair.. just with the same timing with diff vdimm and freq.. not a total let down la.. later update result.


1.66vdimm...


1.68vdimm

1.7vdimm but fail..no time to tweak further.. later cont

not so great.. subtiming all remains as SPD.. except few like twtr, read to read and few other i loosen up..
so far that is the best with my current noobish skill.. and also 700series mobo..
1600mhz is nowhere to be reach even with cl10.. annoyed.

p/s: tell me if image not clear..since using old CRT, i cant read..mybe u all can..kekeke

Kimu, I can 100% confirm it is the onboard GC holding back! i tested it with onboard GC and my system BSOD!

woot... ur here bro... welcome to d amd family...

happy belated birhtday sir , hardly check d thread yesterday coz busy w/ babysittin...

he has been d most low profile otai for quite sometimes ledi bro.

woot kunta, what sticks or those...

edited: team elite 1333, hmm... considered quite gud ledi, 1600 is more powah coz better chippies iirc...

Hi, i have sorted out my problem.
So I tried again by setting my ram running at 1000MHz, and it works!!!
I can run my CPU at 255MHz now, will try to push it higher later, running Prime 95 for bout 1 hour now and no problem.
Last time system will crash after about 10 mins

Thank you for all sifus for giving me advices

now, are u using add-on GC or change cooling fan?

still internal graphic, stock cooler, will buy later.
i just change the FSB, CPU clock still 2800MHz as i lower down the multiplier as i only want to check the FSB than i can run

Thats it..

Still IGP still the one causing it..Becos RAM Clock are not suppose to run lower than it should..

Have you set it Manually instead of Auto(All settings)?

Temperature really play part on systems.Last time my pwm no heatsinks bang play game sure restart(too hot )..

Now ok jor put heatsinks + lower the volt


NB Volt..i dont know what to use it..i just keep it below 1.15V..Maybe it is useful for IGP overclocking perhaps?

CPU-NB Vid is suggested <1.4V..

I tried 7600GS, but system still crashes when FSB increases.. Only by lowering down the Ram speed, then it wont crash.

What is ur NB speed? Have u tried keeping it as close to 2000mhz? If u oc the NB@CPU IMC did u try uping the cpu-nb volt to maybe 1.25v?
Even tho not ocing ur ram have u tried setting its vdimm to maybe 1.65v? I notice that when we oc our cpu even tho we don't oc ur ram it helps if we supply extra volt to the ram to keep it stable..

NB speed i keep it close to 2000Mhz,i tried to set the Vdimm to 1.65v before but it failed too. I also increase the CPU-NB by +0.1-0.2V also crash.
