The AMD Phenom II OC'ers Club

[Jack Doph]

Well, your RAM should, in theory, not have an issue with the timings you're using, considering it was meant to run at a higher speed with fairly tight timings already.
HT should remain at 2000MHz - there's zero gain to be had from raising this and the same for its related voltage (Auto is fine, unless you start raising the 'FSB').
NB is always going to be a bit tricky: some boards and CPUs can handle 3000MHz without an issue combined with a minor voltage increase.
Other boards/CPUs (like mine :/), refuse to be stable over anything greater than 2600MHz, no matter what.
The trick is finding the sweet point here and that simply takes a lot of time in stability-testing.
VDDA can remain Auto as well, as this simply helps to feed more voltage to the CPU when stressed.
I cannot find the link that properly explains VDDA, but in effect, it's similar to LLC (Line Load Calibration) in its function.

As has been mentioned before - OC each component individually, before going to the next: CPU max OC, then RAM, etc.
Be patient mate

I can't say anything other than *jealous*.
You must have the Golden Samples of everything to be able to get away with those figures mate.
How on earth is your system stable with that OC and those voltages?
Again.. *jealous*

If my understanding of VDDA is correct, this can never go below 2.5v anyway (limits tend to be 2.5v-2.8v) - more would eventually fry the CPU, less would starve it to shut-down.
Those are still awesome figures mate

EDIT: *more than 2.8v

 

[Corduroy_Jr]

thanks man, and yea it allows me to set 2.2v vdda in bios but get this in bios still reads and 2.5 and windows but overall i guess i am happy with this unlocked phenom II 555 x2 over my phenom Ii 955be i sold

AMD would be kicking themselves, knowing you got an X4 for the price of an X2
AND OC better than at least one other REAL X4 XD

If you think that's a Golden Sample, what do you think of YautjaLord's cpu, it does 4.0Ghz with less that 1.40v, mine needs 1.52v to do that. To Jack Dolph: What do you mean with "less would starve it to shut-down"

By default, the CPU gets fed around the 2.5v mark from VDDA. Less than this (or more than 2.8v) would cause the CPU to shut down, as the internal memory cannot sustain a working function reliably whilst undervolted (or volted beyond 2.8v).
Damn I miss that link now :/
What it comes down to is the margin of error. In the case of VDDA, this is kind of last resort (my bad if this is phrased incorrectly) of stability. Beyond or below this, the CPU's ECC cannot correct any further (as well as other things) and thus causes itself to shut down.

My apologies for not remembering the exact wording :/

 

[de.das.dude]

OH MY GOD! my silly sample doesnt even stable @3.6GHz at 1.4V!

 

[Corduroy_Jr]

just updating work in progress so far stable for a hour

Cpu voltage 1.3750v bio, in windows 1.380v to 1.392v full load
CPU/NB voltage=1.1750v north bridge was 2600mhz now 2800mhz 1.250v
VDDA voltage=2.2000v but in windows 2.5v
RAM voltage=1.5v
NB voltage=0.9v
HT voltage=0.9v ht was at stock 2000mhz now 2600mhz
SB voltage 1.1v
video card around mid 60's tops full load some games less
cpu idle high 20's, full load low 40's

[de.das.dude]

just a random question. are the CM extreme Power series good?

i have CM extreme power plus 700w and it dont have any problems at all, been using it for my old machine and my current for about a year

I admit, i'm a bit erm.., non-sober (sorry for off-topic - 2 "Winter" cocktails + 1 Rami Martin rum, lol) so i ask : you say it to me ? Celebrated my bday today, so forgive me; i also raised a toast to you all people.

Also - CPU max OC, what do you mean ? Max stable ? Unstable was 4.1GHz (unfortunately), but even 4.0GHz is enough - imagine what temps i would get if i'll apply the Indigo Extreme ETI (one for Socket AM2/3). RAM stable frequency (with 4.0GHz) is 1333MHz 24/7 i beleive; not raising it higher : LinX gave me error on 15th minute (from total of 75min) when i lowered the multi to x20.0 but left the RAM freq @ 1600MHz.

Thanx mate nevertheless, all knowledge is good knowledge.

Are you watching the IPL?

OK, with max OC I just mean one should OC their CPU first (max OC that's stable) and then start on memory OC (timing first, then NB frequency, etc.).
Guide your OC with safe voltages and you will find the sweet spot for your system.
Again, this may take quite some time (maybe even a week or so), but you'll end up with a system that's both fast AND reliable, under any circumstance

 

[YautjaLord]

Sure no prob mate.

Just let me get the cash & than this Indigo Extreme ETI & i'll conduct something by end of May, just before FX-8130P comes out. Gonna be awesome year : Deep Purple, Grave Digger & Napalm Death come to Israel (metal); i find job in Web site building (self-explanatory ); FX-8130P & Crosshair V Formula come out (PC); and i manage to OC my CPU to desired frequency soon. Stay tuned.

@YL (hope you don't mind me shortening it)

Any more updates on your overclock? I want to see what you can get as a final stable above 4Ghz

OH MY GOD! my silly sample doesnt even stable @3.6GHz at 1.4V!

@Corduroy

My stinking rig locks whenever I try to run without PhysX enabled. Something to do with drivers I bet.

well, mines a crappy 95W though. still got it to 3.9GHz once.

Was directed at triple D.

Sounds like a degraded chip. You ever run it over 1.55v core? This thing is a finicky cpu-nb clocker, as I said before thats why I think it was binned as a dual. I mean not even supposed to be able to enable CnQ/C1E while unlocked, this chip has no issues handling it when unlocked.

I COULD run 4Ghz 24.7 but I do get frequent stability issues, but I am thinking it's due to the board/ram combination.

No i don't mind.

Later on. Ok ? Maybe end of May/just before the AMD's FX-8130P & Crosshair V Formula arrive. 4.1GHz - but only after i'll buy & apply Indigo Extreme.

 

[Corduroy_Jr]

dont feel to bad i get the odd stability problem's with core unlocker, every now and then when it crashes or forced to press reset button, i have to shut off the extra two cores the reenter bios a few times then enabled core unlocker then go in to bios 2 more times, kinda sucks but ill i am willing to take the good with the bad

Can you see your core temps while unlocked?
