AMD® Phenom™ II Overclocking Thread

Hello my Brothers (& Sisters), I would just like to inform you there is every possibility that this thread will be viewed by a lot of people around the world including maybe representatives from AMD® etc . . . I am hoping we can demonstrate what fantastic, friendly and capable bunch of overclockers the crew @ OcUK are . . . I'm gonna do my level best to make this a fun thread and I hope you guys (& girls ) enjoy!

If any of you have Photoshop installed it would be great if you added your name and a little bling to the screeny, if not then try to make sure your name is in the image somewhere (even a .txt document)

Can I also suggest that in an effort to make the thread easier to read that we do not use quotes at all . . . It's ok to call a person by their user name . . . I'm sorry if this seems like nit-picking but you would be surprised how much easier a long thread is too read without excessive quoting . . . I illustrated this concept of a "completely" uneeded quote for you in the image below, there is enough original text in the thread without having it repeated (again and again), the idea is that this "improves" the thread as a Technical Resource for those that follow later . . . . thanks in advance for your cooperation!




I'm gonna be *lifting* some peoples screenshots out and using them to fill the "Screen Of The Day!" section in post #2 . . . Also don't forget some people will be *viewing* using a laptop so keep the image dimensions reasonable and fill the space with as much useful stuff as possible (temps, stability, Memory timings etc) . . .

I get the impression that these chips perform better & better the more cooling you can give them . . . i.e they may really take off if you can keep the load temps at 40°C or even lower! :) . . . See what the others say . . . I'm not an expert here! :o
 
Hey Uriel, you just made Screen Of The Day!

I'm impressed, for the money you paid I do believe you have *Out-Banged* me with my AMD® Athlon™ II X3 425 @ 3.6GHz . . . I will compare some tests with you once you get everything maxed and to your liking! :)

IntelBurn 2.4 (standard settings) fails with my northbridge clocked to 2400. Backed down to 2.1 GHz and it passes 5 tests.
I'm looking at your screenie now and I am wondering how the temps are? . . . I can't see CoreTemp or any other temp program . . if you can somehow squeeze this in to your beautiful screenies it would be handy! :)

I'm wondering if the IMC is feeling the heat? . . how are the temps? ;)

can someone tell me how to do a sreenshot to post here?
Gimme a bell mate I'll talk you through it! :)

That looks great! . . . Did you get time to run any Prime95 Blend on that? . . . 4GHz prime stable quad core would be quite something! . . . can you include maybe CPU-Memory tabs also please (you can open multiple copies of CPU-z no probs), apart from that great result and good screenie!

EGuitarStar
great result but sadly your posting it in the wrong thread as your using a RANA core, can you edit your post down to a smiley and please repost your results here . . . AMD® Athlon™ II Overclocking Thread . . . thanks very much I am getting loney by myself in that thread haha! :o

~>Dg<~
That looks promising . . . I think? :p I can't see much info in your screenie! . . . any chance you could include a few more apps like CPU-z showing main tab and memory tab, that would be great and I thank you in advance for your efforts!

pieman109
Looks good to me, that's the first Callisto to be posted up, nice screenie too, any chance you can include CPU-z memory tab please (you can open multiple copies of CPU-z no probs). The Baram is a great cooler and totally overkill for me using a Rana Core but very appropriate for anyone using an Phenom™ II with it's big fat slab of Level 3 cache which I believe generates a lot of heat once overclock! . . . Also did you overclock the CPU-NB yet?

Uriel
I just remembered the thing about not being able to monitor temps once the chip is unlocked haha! . . . anyway you sure do qualify to publish your results in this thread, at the moment your the Bang-for-buck champion, I'm tempted to make a purchase just to dethrone you hehe! ;)

Hey bigjimmyauk, that is looking promising :), I wonder what is holding you back? . . . You forgot to add your name to the screenie and half your screenie is bare desktop! :p

What fan have you got on the Baram or is it running passive? . . .

To anyone else that is having problems getting 4.0GHz stable I am thinking it's either temp related, lack of vCore or CPU-NB vCore or something else random?

Hello Elfmeister,

I wouldn't say there is a *best* way to do anything but rather what works best for you. All the lucky owners of a Black-Edition chip get a fully unlocked CPU multi so that should be exploited to the max although it is not the be-all-and-end-all of the overclocking process . . .

gareth170 did quite a nice thread called "my phenom 965 c3 clocking" which you can find here, that should give you a good idea of what the procedure is, he also linked up an interesting document written by AMD called: UNLEASH THE DRAGON which outlines the the method of performance tuning an AMD® Phenom™ II system . . .

I'd say that once your certain your system is all nice and stable while at stock speeds and you have monitored temps and run a few benches and games your ready to begin . . . all you need to do is slowly but surely crank up the CPU multiplier and run a stability diagnostic, play some games, watch temps then rinse and repeat. As soon as the processor falls over and crashes your system then you just need to boost the vCore until it runs stable again, keeping an eye on temps etc . . .

At some point with this CPU Multi clocking you will hit a wall where the processor will not run stable no matter how much vCore you give it, this wall could be due to either temps running to high or the fact you have maxed the CPU. if you suspect its the temps you can trouble-shoot this by putting on some warm clothes and then opening all the windows and bring your temps right down and test again. Although this freeze-ya-behind-off method is not a sensible long term option it serves a function by allowing you to know if you have hit some thermal-wall or not, the Deneb silicon becomes *enchanted* and can work magic if you cool it enough . . . If your stability problems go away once you and the system are frozen you at least know that you need better cooling!

Once you have worked out the max CPU MHz your ready for the next stage which is to test the CPU-NB where the IMC lives, again all the lucky owners of a Black-Edition get an unlocked multiplier so with the rest of the system at stock I believe you can just increase the CPU-NB multi and do some stability tests, once the CPU-NB (IMC) begins to strain you need to boost the voltage. The CPU-NB runs at default 2GHz but hopefully you will be able to get it running at 2.6GHz with extra juice . . . the same freeze-ya-behind-off method can be employed if you begin to hit stability issues. I am using a slightly different core (Propus/Rana) to you and had some stability issue myself but these went away once I improved my cooling so bare that in mind, I think the IMC doesn't like the heat! :p

Once you have a rough idea of the CPU max and what volts its needs and the CPU-NB max and what volts that needs your ready to try overclocking them together, this may produce different results as the combined extra voltage from both the CPU/CPU-NB will undoubtedly push the temps up a lot more than when you just clocked them one at a time, so don't be surprised if you run into some problems that were not there when you tested them separately . . .

Everyone has their own personal method and pace to go about this but I personally like to take it nice and slow, the problem I have had is that the stability checks do not always show up a problem, Prime95 passed an 8-Hour blend, IBT passes many loops but the system may just reboot when you sitting there surfing? . . . the way I got around this was to just use the system for a day or two, play some games etc just to be really sure there isn't a little gremlin in the works . . . only once I'm sure the overclock is robust do I push on. Patience is the key thing here, give yourself plenty of time and don't rush things and you will be fine, by all means feel free to keep posting up your work in progress and ask any questions you need!

Eventually you will hit the max where no matter of extra voltage or freezing temps will net you extra MHz so your ready for the next stage . . . I notice you are using the same motherboard as me . . . although yours is with mismatched DDR2 . . .

For the sale of keeping things simple and I would suggest removing the 2x1GB of DDR2-800 and do your testing with just the 2x2GB of DDR2-1066. To get these sticks running at full speed your gonna need to set the HT ref. Clock to 267MHz while the sticks are set in the BIOS at DDR2-800 (which is default), of course by adjusting the HT ref. Clock your changing the base speed so all your other clocks will most likey need adjusting by lowering their individual multis. Bare in mind that by running the Memory at DDR2-1066 alongside an overclocked CPU-NB there will be more strain on the IMC so you may need to boost CPU-NB voltage to keep everything running stable . . .

Well didn't mean to go on so much there but that basically covers it, you got lots of things to overclock but you can do them one at a time, plenty of stability testing as you go and keep a note of what settings you are adjusting in case you forget . . .

Need to know anything more then just ask! :cool:
 
bigjimmyauk
Wow man your getting some good results! . . . 4GHz processing and 2.6GHz CPU-NB is great especially with temps @ 28°C-51°C, nice screenies too so well done your screen of the day! :p . . . look forward to any Prime Blend results you can submit!

Muel
Hey man don't be afraid and don't doubt anything, use the force! ;) . . . you say "at anything over 3.8ghz blend fails straight away" . . .why do you think that is? . . . is it the temps or is it the volts? . . . don't give up just yet as you have a AMD® Phenom™ II X4 965 and I think it could do more! . . . yeah I hear what your saying about TDP but I don't think you need worry just try your best to keep everything cool and you will be fine . . . is anything hot inside your system? . . .Once you worked out the big clocks you can then figure the more reasonable day to day settings, anyway good luck and look forward to any Prime Blend test reults you do!

EGuitarStar
Sorry about the confusion, It did look just like a Rana core from the screenie, thanks for the heads up . . . Regarding +MHz/-Cores vs -MHz/+Cores the answer will be it depends on the application you are using, old games will run faster with +MHz while newer games will probably run faster with +Cores . . . Multithreaded software such as video-encoding and 3D-Rendering will probably be a lot faster with +Cores also . . nice you have a choice! :D . . . once you work out the best clocks for both you can do some benching and share your results with all of us here!

Elfmeister
No worries! . . . hope you picked up a little insight from my ramblings heh! . . .can I ask what is your past overclocking experience and have you done BIOS clocking before? . . . If not then you may find this program interesting! AMD OverDrive™ . . . how long has your system been up and running?

SMAndy
Take your time . . . 4GHz will be still there in a week or two! :D . . . I'm not actually sure what chip your using? . . . did I miss that somewhere! . . . 3.5GHz Processing & 2.47GHz CPU-NB/HTT is very fast, look forward to seeing what you can do with Prime95 Blend! :)

~>Dg<~
The disparity between the voltage you [key] in the BIOS and the voltage you see in CPU-z & BIOS health page is perfectly normal, it's something known as vDrop and it's nearly always been like that, don't worry about it and pay attention to the figure in CPU-z & BIOS health page as thats the volts the chip is getting, doesn't matter if you [key] in 1.70vCore to get 1.55vCore in CPU-z! . . . I'd say 1.3v CPU-NB is a nice figure, I would go higher than this but you need good cooling. 2.6GHz CPU-NB os a nice figure to aim for, I noticed by 3D-Benchmarks jumped up quite a bit with a boost to Northbridge speeds . . .

eddyc
Really nice result there! :) . . . AMD® Phenom™ II X2 unlocked to X3 and overclocked to 3.8GHz, good screenie including 25mins Prime Blend as well, good work, if you get time see if you can get a big Blend run off. Once you worked out the CPU clock then for sure some extra CPU-NB MHz will sweeten the deal but best to do these things one at a time. I'm interested to kno . . . did you do any testing on the chip before you unlocked it or did you unlock it and start clocking? . . . I also noticed you clocking your IGP, I did the same and have some info you may or may not find helpful . . the last setting was stable but the northbridge started getting quite hot so need to get some extra airflow on it to keep it cool and happy!

  • 700MHz 1.100v
  • 750MHz 1.205v
  • 800MHz 1.205v
  • 850Mhz 1.310v

Yeah no worries, It is a great cooler and I'm suprised more people didn't get one . . . Push-Pull Baram!! :eek: . . . I was gonna call you an OverCooler but actually that makes a lot of sense when combined with an overclocked & overvolted Deneb! :D

I think all the magic happens when the chip is kept below 30°C-40°C load . . . look forward to your results and maybe some pictures if you can managed it! :cool:
 
Hello Guys! . . . sorry been away from thread a few days, lots and lots of good results, thanks for all the good contributions and I hope you all still have some timne to get some gaming and other stuff done. I am interested to know what games some of you have been playing, GPU and what res? . . . I'm also interested to know what systems you has before these AMD® Phenom™ II's . . . also can we have a little bit of a Star-Wars theme in one or two result screens please (if you can squeeze it in of course!) :cool:

eddyc
Really good result there, lovely triple core @ 3.8GHz with over 8 hours of prime on the clock, great stuff and great screenie! . . . in fact that has to be Screen Of The Day!! :D

puma luke
Nice start there, good results and good stability testing too, keep it up and can you lob an extra copy of CPU-z showing the Memory tab in your screenies please! ;) . . . also you seem to have some uneeded [/IMG] code around your images? . . . did you try an unlock yet? :D

bigjimmyauk
Your a crazy man but I like you! :D . . . those temps are brillliant . . . 43°C full load! . . . . credit to you and credit to a PushPullBaram! :p . . . I think some experiementation is in order to work out a good CPU/CPU-NB/HTT combo, I found that the CPU-NB boost was quite good, I suppose people need to do some testing . . . How is the 3.9GHz stability coming along?

Muel
Haha, I'm not sure if a leaderboard would make much sense because . . . your all #1 :) . . . just make sure you get a top clock from your chip because the other guys want to make your flagship look bad . . Also is SuperPI for Intel® chips or AMD® chips? . . . I thought it's an Intel® Promotional tool? . . . anyway happy clocking ya lucky so & so! :D

buttkinz
Wow that looks great, a nice unlock, a nice clock, a decent pair of boobzillas on the desktop! :p . . . . don't forget to include your name on the screenie and perhaps make it just a tad bigger is you can, keep clocking! :)

SMAndy
Give the chip some juice and get that CPU-Multi jacked, may be easier to clock one thing at a time instead of a rumble in the jungle, look foward to your screenies! :)

joewm18
70°C load is ridiculous!!! :eek: . . . are you overclocking many things at once btw? . . . or did you clock things up one at a time? . . . if you newish? I'd leave pretty much everything on [Auto] and work out your processors clock first . . I expect good things! :cool:

Damien
Welcome and nice start to your clock! . . . that system musy fly!! good screenie too, whack open another CPU-z so we can see your [mem] tab and NB settings please, also don't forget to include your name in the screenshot somewhere please! :D

Martini1991
Ah Welcome Deneb Master, May the force be with you! . . . now where is your screenie please! :p

Si Lad
Hello there, nice result there man and great screenie, I'd say once you max that chip your ready to crank the CPU-NB a bit! :)

timmy222
That looks sweet man! . . . Callisto in the house!, nice screenie, bit more apps in view would be great and dont forget your name on the screenie! ;)

Skillmister
Welcome, I'm jealous! . . you bought a dual core and now you have a quad core . . . hmmm happy camper no doubt! :D . . . P.S the ThermoLab Baram is worth every single penny and fits fine in an Antec 300! :cool:
