AMD® Phenom™ II Overclocking Thread

kellaway225, the whole thread is Deneb processors? . . . .ever single person posting results in this thread are using "almost" identical chips and even though people are using different motherboards the settings are the same (albeit some with different names in BIOS) . . . what ever processor speed you want just divide the figure by 200 and then set the processor multi to the nearest match i.e 3500 divide by 200 = 17.5 . . . all you need to do is set the CPU multi and set the vCore, thats it, two settings, the vCore will vary from chip to chip but say you start at 1.35vCore and then slowly nudge it upwards until you find stabilty! . . . . if you look at peoples screenshots you should be able to see the vCore figure showing in CPU-z, this should be close to what you will need if you want to match the same speed . . just keep an eye on temps and get cracking! :cool:
 
Hello Concorde Rules, long time! :) . . . those settings look pretty good . . . are you giving the readings for all those volts or is that what you have set in BIOS? . . . the only two voltages that look like they need setting manually would be vCore and vCPU-NB? . . . all the rest should work fine at the speeds you have set on [Auto] . . . . the CPU-NB should clock up to 2.5GHz using lowish volts (or even auto) but beyond 2.5GHz then 1.225vCPU-NB should be a good starting point for 2.66GHz . . . . have you tried giving the chip some more plain-jane vCore?

[edit] I just saw you state the CPU multi as "10x" . . . 10 x 266 = 2660MHz Processor? :confused:

Hello Concorde Rules, can I point you towards the "Welcome Post" please! :D . . .

With that low CPU clock you could probably use [Auto] vCore, if you drop the CPU-NB multi to [x8] that should run fine on [Auto] also . . . basically all volts on [Auto] . . .you may need to add some vCore and you may need to add some CPU-NB voltage depending on what multi you set! :cool:

Concorde Rules, its any colour really or no colour at all! :p

AMD® Phenom™ II X2 550

With DDR2-1066 I would probably try 3192MHz (12x266) with CPU-NB/HT-Link muti dropped to [x8] for basic testing . . . that should work entirely on [auto] volts for everything with the possible exception of vCore? . . . . once you worked the basic CPU-Frequency vs vCore out you can begin tweaking the other settings (CPU-NB/Ht-Link etc) :cool:
 
burtieb1, what temp readings are you getting for max CPU load under HWMonitor . . . the last screenie you posted showed a max CoreTemp of 59°C . . .when you say "Stock Volts" does that mean the vCore is on [Auto] or you manually set it to match the processor VID? . . . . Asus Crosshair III Formula + Corsair H50 nice! :) . . . when the chip is loaded what vCore reading do you see in CPU-z? . . . does it change or move about?
 
Gareth: While I am not specifically disagreeing with you I think its important were careful on what we say is "fact" and what we say is "I believe its true" . . . I do use both CoreTemp and Hardware monitor and there is a difference between the readings (HWMonitor is higher sometimes) but CoreTemp does a reasonable job? perhaps the Propus die is different from the Deneb die? . . . It's confusing reading the CoreTemp webpage here

"AMD chips report the temperature by a special register in the CPU's NB. Core Temp reads that register and uses a formula provided by AMD to calculate the current temperature"

How does that work then? :D . . . it uses a "formula" to calculate the temp?
 
Hey burtieb1, so that does seem quite warm then @ 3.6GHz and the vCore is fixed at 1.400 and you have pretty decent cooling? . . . Hmmm so can you arrange a screenie or detail the exact temps you are seeing in Hardware Monitor & CoreTemp? . . . are you saying CoreTemp is showing higher temps than Hardware Monitor?
 
burtieb1, have you tried closing Hardware Monitor and re-opening it? . . . I found that sometimes it doesn't pick up all the sensors . . . . closing it and running it again sometimes makes a few new temps appear? . . . you seem to be missing TMPIN1 :)
 
kellaway225, as mentioned to you before can you please read the "Welcome Post" and preferably the whole thread . . .I've asked you politely not to keep quoting me but you do it anyway? (post #1411) . . I've asked you to the thread and understand the overclocking process a bit better before jumping in and you don't appear to have read very much at all? . . . the questions and answers you seek have already appeared again and again in this thread . . . . It would be great if you could make a little more effort, its very simple really, just leave all voltages on [Auto] except vCore, turn vCore up until you get stability? . . . how can you have missed this info? :confused:
 
Just wondering if anyone has done any undervolting tests yet? . . . . either at stock clocks or with a mild overclock? . . . . interested to know if anyone can get an 8 hour blend test off using quite low vCore? . . . . I'm thinking approx 3.0GHz-3.4GHz should be possible with maybe 1.200vCore? maybe a touch more? :cool:
 
Hey thingemajib, there doesn't appear to be any disadvantage to overclocking using the IGP, at least I have not had a problem myself and have no read about a problem? . . . I'm aware that in the past that an IGP limited the clocks on some uATX boards but this situation seems to have improved greatly since then! :)

Btw: not sure if you have read the Welcome Post or how much of the thread you have read but did you spot the bit about me asking to avoid quoting if at all possible? . . .you seem to have ignored this and gone right ahead? . . . . sorry to nag you but can you delete the quotes from your previous post and maybe use the persons name? . . . thanks for your co-operation! :cool:

Fonz-Valo Please "No Quotes" . . . please!
 
Well picked up the AMD® Phenom™ II X3 yesterday and pulled the system from under the desk to get the processor installed . . . been several months since I last swapped out chips so a wee bit of tomb dust had gathered on the heatsink! :eek:

Lobbed The Mummy out the window and got the evil remains cleaned out with a hoover! :p . . . . chip installed, nice fresh layer of AS5/TIM and plonked the Thermolab Baram back on top and secured before finally getting a trusty Akasa AK-FN053 120mm Smart fan clipped back on . . .

Now everyone has their own style of OverClocking and mine is a slowly but surely approach . . . I start off with the everything on [Auto] for a quick burn, check temps etc then I begin Voltage-Scaling tests with the processor at stock MHz I manually adjust the vCore downwards until the PC becomes unstable and then nudge the vCore up a few clicks so the processor is stable enough to pass at least eight hours of Prime95 Small FFTs and a quick 20 loops of IBT . . . once the basline vCore is established I start overclocking the processor and nudge up the vCore enough to get it stable . . .

This particular Phenom II X3 720 (2.8GHz) has a [VID] of 1.3250 but managed to run stably with 1.184vCore . . . not to bad . . . with that done I change only the CPU multiplier upwards from x14 to x15 to get a nice round 3.0GHz with [1.2250]vCore set in the BIOS and left that running Prime95 Small FFTs for 8 hours . . . . first result below . . . more to come . . . as I said I'm a slowly but surely kinda guy! :p

frozennova: Yeah just plodding along . . . these Black-Edition chips with the unlocked CPU multiplier are so easy to clock . . . thought I may as well publish each step so anyone who still doesn't understand much about clocking can get a better idea of the steps involved . . . I picked up a second AMD® 785G AM2+ mobo made by gigabyte (GA-MA785GM-US2H) and have to say the vCore line is rock solid . . . currently using that in another machine with the AMD® Athlon™ II X4 630 . . .

Didn't get round to testing the unlock on this AMD® Phenom™ II X3 yet . . . that can wait till all the testing is completed with it as a straight up TripleCore, get the vCore scaling stuff done first then have a fiddle with the CPU-NB MHz and stuff like that . . . once that's all done will see if it unlocks . . . I actually only need a TripleCore for gaming so not too fussed if it unlocks or not . . . if it does unlock then that means another whole bunch of testing which I'm not keen on doing just atm! :p

I like the look of your C3 stepping AMD® Phenom™ II X4 . . . 4.0GHz at approx 1.400vCore is awesome . . . I'd like to see some serious stability testing done on that? . . . 34°C-50°C looks really good! :)

thingemajib: Good to see another C3 4.0GHz clock! . . . 1.552vCore eh? . . . how are the temps under load at that clock? . . . also what processor is that you unlocked? . . . an X2 or an X3 or? :confused: . . .

All my image hosting is done using http://imageshack.us/ . . . not sure whats goings on with you seeing black lines through some images? . . . could it be something I'm doing wrong? . . . a problem with ImageShack or perhaps something at your end? (display issue?) . . .

buchtis: Hey AMD® Phenom™ II X4 @3.6GHz is nothing to sniff at . . . that's plenty fast for you surely? . . . You got a C3 stepping as well you lucky git . . . does it need 1.456vCore to run stably @ 3.6GHz? . . . did you work your way up to that clock or just straight in at 3.6GHz? . . . did you try any higher yet? :D

Not sure whats up with your HWMonitor fan readings? . . . are they all 3 or 4-pin fans connected to the motherboard or? . . . would be good to see some stability testing done in your future submissions . . . makes the screenies more useful if people can see the chip under pressure . . . idle/load temps etc! :cool:
 
buchtis: When you get a few hours spare then read this thread through from the beginning and everything you could ever need to know will be revealed to you . . . as an incentive to plough through nearly 2000 posts there are still some "unclaimed" free gifts hidden in this thread so get reading! :p

PapaLazaru: Another nice result from a C3 revision! . . . its always appreciated by the viewing punter if the screenies shows a loaded OverClocked processor with Idle/Loads temps and any other technical info you can squeeze in . . . I'm sure that processor has a bit more to give! :cool:
