That's correct, for the time being I have both my NB freq. Multiplier, and my HT multi @ 5.0x each, just for the sake of easy testing. Right now I'm trying to bench 3744 @ 208x18 with 1.38v, giving my NB freq and ht link values of 1040 each.

I'll play around with the NB and HT when the time comes, but for now its the cpu!

Do what you gotta do! 3744MHz on 1.38 volts is impressive... so keep up the good work! We need to figure these chips out!

Ok so lowering your nb and ht link to lower multipliers like you have done, and lowering (for the sake of this question) 1066 memory to 800mhz will take all of them out of the equation for trying to find your max stable cpu overclock, correct? I'm still learning.. what should I lower mine to to take them out of the equation? Also I went in and disabled amd cpu1e, amd live!,tlb fix, cpu instruction fetch, and processor downcore. Should I turn off the cpu tweak control? Im un sure of what that will do..

Also what I am seeing on this chip is, I can hit 3.6x by just about any combination and on stock voltage. once I see 3.7x no matter where I put the voltage its completely unstable. I even got a 3.8x once but again unstable.. Funny thing is cooling is not my problem.. @3.67ghz @ 1.39v under load for 4 hrs it never went past 46c grrr... I got this thing to boot all the way up to 4.4ghz but it BSOD's within 10 seconds.. Is Vista 64 our limiting factor?

From my experiance, Vista 64 is a bit tougher to achieve a higher overclock. I could get my 9850 to 3GHz in Vista 32 but only 2.7GHz or a pinch more in Vista 64.

I believe it should, the only reason this would be bad would be if for some reason, your cpu or mobo liked high ht links, high NB clocks. I couldn't see a reson for this unless there was something wierd going on, but like you I'm just learning (first phenom). I know that certain chips have a max NB speed given a certain vcore and mobo volts, and that if you exceeded these it would cause instability (whereas your coreclock might be fine at that voltage). Best to lower them if you can, you can always test how they work clocked higher later.

One key thing to remember (at least I think this holds true for phenom IIs) is that your HT link should be < or = your NB frequency or it can cause instability. I've been going by that rule anyway.

And yep, you should disable cpu tweak, its only for the tlb fix regarding the older phenoms which had the bug. Does nothing for the phenom II.

almost the same here, I can hit 3.57ghz OCCT stable on stock volts. getting to 3.7 is fine as well, and only takes me 1.38v. I'm having a b***h of a time getting 3.8ghz OCCT stable. Looks like I may have to just start pumping the juice.

Yeah, I'm wondering if I should install Windows 7 and give that a shot, people have been saying that both XP and 7 are easier to reach stability in (x64 or x32, with x64 being worse). My computer is also in bad need of a format right now, but I just cant stop oc'ing ><

Edit: interesting note. Something I'm going to have 'fun' playing around with, wondering if i can get this OCCT stable. It loaded Deadspace, RA3, played for five minutes to see if it would crash. Also posting with this clock atm, however I doubt anyone would have such a high OC if their NB freq sucked, would hurt game performance (have not tried maxing my NB yet). Note: this has NOT been tested for stability yet with occt/prime, and it'll most probably crash... but its useable @ 3.92, 1.4v, which is interesting.

I just found my MB's MAX FSB.. 263 Prime95 for 4hrs, id say thats pretty good.. so next im gonna find the memory FSB, then the CPU.. I have hit so many walls with the CPU. I think it would be wise to find all the rest of the MAX FSB's first to know where not to take everything. How the heck do you do a dual boot so I can try XP? I have XP 32 and 64 Bit.. And what is WINDOWS 7???

DRIN: Your what specs did u use to get to 3.92?

Well, I reset my Bios back to default, i'm going to update my bios and start over with the OC, since I have the next 3 days to mess around. I also just noticed when I went in to look at my settings, that I was running with unlinked ram, which would have probably given a nice boost to my bench scores. If you guys are interested here are the benchmarks I ran yesterday. I think 06 and 05 are right on, but vantage and 03 need some work (which is an understatement).

If you don't want to check the links:
