AMD® Phenom™ II Overclocking Thread

wayne - I just disabled 'Enable Adaptive Anti-Aliasing' on my ati catalyst control centre. I am suddenly getting much better frame rates off my IGP. Give it a go if you have it ticked at the moment.
 
Gareth: I was wondering about your OCCT vCore ripple results, is that the same figure you see in CPU-z? . . . does the vCore "fluctuate" at all? . . . I ask because I've not ever seen 0% ripple and I am wondering if perhaps the wrong sensor is selected in OCCT?

gurusan: Did you just suggest an oscilloscope for accurate vCore readings! :D . . . nice results and screenie, you forget to include your name! :)

eddyc: Thanks a lot for that Loadline info, it basically reduced the vDrop (nice!) and the vDroop (nice!) but the Ripple was unaffected (boo!), it's not really causing me a problem but I prefere flatlines heh . . . re the Adaptive Anti-Aliasing thing, I've never touched a setting in the catalyst control centre apart from OverDrive! (is there any good stuff in there?) :D

I dont really know what most of the settings are TBH. I have just got them set so that the individual game manages the settings. I think I set it to enable the adaptive a-a when I first set the comp up. But the problem with looking at that little 3d screen they give you to test the settings is that it is not nearly as demanding as most games so it is not really very representative. I reckon most of the settings would be good but end up just making more demands of the IGP during game play and slowing the frame rates down.
 
Big.Wayne, i've watched the voltage in cpu-z, everest and the voltage doesn't jump up or down while under load

but if i set the voltage to 1.425v, it idles at 1.408v and 1.425v under load but doesn't jump up or down while under load...

at 1.45v it stays at that all the time, idle/under load.

FINALLY! - All that talk of 1T/2T on here, got me thinking. Corsair and Asus forums wern't of much use - The only memory setting I hadn't changed were timings as I presumed the motherboard picked these up from SPD.

CPU-Z still refuses to show me the SPD settings for my memory so I jumped on corsair website for exact specs - turns out its 9-9-9-24/2T!. Changed BIOS manually to 2T and et voila - ran 10 hours of prime blend yesterday during the day no problems.

Just to double check I left it running over night too - 12 hours stable on prime95 blend! - AT LAST!

Time for some OC-ing, finally!. Quick try the other day (2hrs prime) gave me 1.4v @ 3.8 (which is quite good! - hope it holds for 10hours today) and 1.5v @ 4.0 (which wasnt having it). I'd be more than happy with 3.8 as I'm not an extreme OC-er - just want it stable for 24.7 use without pushing too much.

For best results should I aim just to use Multi's or push the FSB? - I don't really need to push the FSB as the memory is already performing @ 1600 thanks to the motherboard sorting that, or should I? :)

yeah CPU-Z doesn't show the SPD settings on some memorys

but some motherboard bios's show the SPD settings , (mine does)

great it's working for u now mate..
 
Thanks fellas - you guys give better advice than both the corsair and asus support forums :)

Just been testing with the multi's -
1.5v @ x20 (4Ghz) - prime95 crashed whole PC straight away.
1.55v @ x20 (4ghz) - prime95 ran for 10minutes then crashed and burned.

Obviously safe to say 4Ghz is going to need super power so as not to keep things to the extreme I ran 1.5v x 19.5 (3.9Ghz) - which ran for about 20minutes but I wasn't happy with the high voltage so stopped it.

Dropped it down to x18 Multii (3.8Ghz) now working on stable voltage as I don't like extreme OC's - 1.425v - primeing on Small FFT's and will report back.

Thanks for your help in the meantime guys :) mucho appreciated.
 
Just to mention again, if anyone has any spare "testing" time I'd be grateful if a couple more people could run the OCCT test and lemme see the vCore chart please! :)

OCCT 3.1.0 here

My results here

As has been mentioned by gurusan these results may not be accurate but I still wouldn't mind getting some comparisons, only seens Gareths so far . .
 
Lol! Pneumonic :D . . . Is this "rig in pieces" overclocking related? . . . I am reminded of the scene at the end of the Blue's Brothers where the car just falls apart after being pushed to the brink! :p

ta dude - will check that out once I gots me a stable 3.8 ;)

Which is the best Prime test to run - Blend or small FFT's when checking for 100% OC stability on these Phenom II's please? thanks.
