@Munki

I'm just wondering why you need over 1.4v for 3.6Ghz?! My unlocked x2 does that @ 1.33v. Have a play around with ACC and maybe a notch or 2 with cpu/nb voltage.

Ya know...i don't think I touched the voltages.

At this rate....3.8 is gonna be it for me :/

Just bumped the multi up 1 since last SS.

did you ever touched the HTT and/or played with the NB clocks/CPU-NB Volts?

 

[crazyeyesreaper]

and for xanlord 4ghz is attainable with air just need a good cooler im running a FRIO with 2x Delta fans on a fancontroller long as i keep the cpu under 55c max load in linpack it will run 4ghz 2800nb as for anything higher its all temps the lower they are the further the PII will go. with fans at max speed of 3300rpm i can hit 4200mhz cpu 2800nb and run games like Badcompany 2 but cant pass linX or intelburntest etc etc

as for munki

already told you man

set the multi to x19 or w.e for 3800 set nb multi to 13 for 2600

set CPU voltage to 1.45 set CPU-NB voltage to 1.3 set NB voltage to 1.2 and you should be able to pass intel burn test. the voltages are a bit high on my cpu but my chip was a water cooled chip before i got it so it should work for you as well because you can probably back the voltages down once stable

Could someone have alook at this post of mine and tell me how I could go beyond 3.8 on my 965 with a Corsair H50?

Hey guys, first time owner of a PII here, and going to need some help finalsing the settings on my overclock.

PII x6 1090T
Asus M4A785-M
4GB DDR2 800

overclock so far is; (prime stable)

3800mhz, 19x200
vcore set at 1.45v in bios, which results in ~1.4v idle and 1.38v load
HT link 2000mhz
NB frequency 2400mhz
ram speed 800mhz effective @ 5-5-5-15 2v (rated at 6-6-6-18 1.8v)

under primes small FFT CPU intensive tests she loads at around 65 degrees using the stock cooler (which is loud at that speed)

could use some help finalising the settings iI've used, I feel I can raise the NB frequency for example but have no experience eith PII's.

any help appreciated, wolf.

 

[crazyeyesreaper]

dude 6 cores if your lucky can go over 3000mhz NB pump that NB up as high as you can get her stable

just dont exceed 1.55v cpu 1.4v CPU-NB to be on the safe side.

also get a way better cooler lol your gonna hit the heat wall before you max the overclock and 65'c way way to hot on Phenom IIs you want to stay under 55'c for best results

the chips are very temperature dependent is the H50 in a push/pull setup? even with the 9600 i have setup for my brother i can hit 50C on it the 965 140w is alot higher wattage...try bumping the volts up or lowering the ram speed to lessen the IMC stress.

just FYI you are pushing 170 watts or so at full load through that cooler with 3.8ghz and 1.475v

Yes, the H50 is Push/pull with two Yate Loons. Temps on Prime 95 stress test do not exceed 50 degrees.
I tried bumping CPU voltage to 1.485 but it still BSOD at beyond 3.8 Ghz. Should I be adjusting some other voltage too?

try playing with your HT clock your chip might not like over 19x also the internal temp monitor on these chips sucks it could just be off and your hitting 55-60C killing any overclock you will get.

 

[xbonez]

I think I'll just stay at 3.8 and call it a day. Since I crunch 24x7, I don't wanna push the chip too much

 

[Munki]

Shut mine down and wouldnt boot back up. lol. Finally got it back up and looking in the BIOS got one stick of RAM running normal (CL9) while the other is being special and running CL8 *yay*

 

[SuPeR FlYYY]

i need a very stable over clock with a x4 965 on air with after market heat sink...looking for it too be very stable and dont really care how deep of an over clock it is...would be happy with 3.7 and beyond...any1 got the specs or info? thanks for any help!

Fill out your system specs on the left hand side. In User Control Panel.

Currently checking stability of 955 BE @ 3.6GHz @ 1.35volts on 6 of 15 threads with INtel Burn Test

So far so good


splat....BSOD

a phenom has 4 threads

dont be down so early. i believe i had hundreds of BSODs in my life during OC. until the BSODing does not begin, its not even real OCing

no no, lol. I know the Phenom has 4 threads. I was talking about the passes on the IntelBurnTest. Im at 1.37v working on the 14th of 15 passes and no BSOD

 

[Munki]

For whatever reason the voltage shown on CPU-Z went up when it finished.

 

[crazyeyesreaper]

told ya munki up the multi till you hit 3800 then up the NB multi till you get to 2600

set cpu volts to 1.45 and CPU-NB volts to 1.3 and run Intel Burn Test it should pass with flying colors

with those temps you have another 8'c of room left before it affects stability and no app on the planet will stress your cpu as much as IBT in terms of temps that when it comes to apps we actually use not bench test and stability test with lol

 

[Munki]

Holy crap...where'd you come from reaper? lol

Well, thats all fine and well. I just wanna know why im doing something ya know? So I can learn something from the experiance

thats called vdroop, or short "droop".its always there,and works as kinda electrical protection mechanism for the proc.. a very good vdroop,OCingwise, is unnoticeably low for the board sensors,and a good is about 0.01v-0.02v..average maybe 0.03... with about 0.4 yours is already quite jumpy, and can make overclocking more difficult for you... you have to start with relatively high volts in the bios, that droop in windows under load, constantly, which keeps you from having high volts in load scenarios
(gaming, video or audio-encoding)
that always have to be calculated, otherwise the OC would be useless,logically.
but, in order to reach the required volts for 3.8 ghz, you need at least 1.4v, which equals in 1.45v you have to enter in the the bios, in order to keep the proc at minimum 1.4 under load.

That makes sense. Currently setting to Crazy's recommended settings.

Last run the BIOS says 1.3875V


nvm. Just hung for a min

 

[Munki]

BSOD before it finished 1st pass:


CPU Voltage @ 1.45
Multiplier @ x19 (200 * 19)
NB voltage @ 1.3
NB Multi @ 2600MHz


Should I bump up the NB voltage?

---------------------------------------------------

Went down with the NB Feq. No help.
Went back to 2600 (NB Freq)
upped the voltage on CPU to 1.475 [FAIL]


These are the last setting if anyone has anything:
CPU Multi @ x19
CPU Voltage @ 1.475
NB Freq @ 2600MHz
NB voltage @ 1.3


Guys with the setting above it was getting hot quick 10 seconds in it was at 51C so that voltage is gonna have to come down I think. Im leaving it off overnight (my baby went through hell tonight )

nn TPU

@Munki make NB V = 1.4V

one other thing too keep an eye on those HDD temps high 40's is not a good thing, hot air is thiner and doesn't give the lift the rw heads need to keep a safe distance from the platers surface...

51's not bad what does it eventually reach that's what counts
