I prefer LinX, its the best stability bench think (example xbitlabs use last months LinX)
and my setings moderadors know from my early posts ,-)

Linx is good but I've run 50 passes successfully only to have it fail 6 hours of prime95. I'd say it's the best for hitting the highest temps, but for complete stability a combination of Linx/Prime95 or OCCT is needed.

Sorry if the list didn't get updated anymore. Had some private issues which has taken all my spare time.

I have updated the lists. If you did submit a stable OC and it did not make it on the list, then you did not post one as gsk3rd already stated:

* Phenom II type (940, 920, 720, 955, 810, etc)
* CPU stepping (printed on the CPU IHS) and manufacturing date (i.e. MCBBF 0109MPM, or whatever you have)
* Revision (check CPU-Z)
* max CPU clock speed, reference clock and multiplier
* CPU voltage
* CPU-NB voltage
* Northbridge clock (check CPU-Z) and voltage
* HTT link speed and voltage
* motherboard used
* motherboard BIOS revision
* type of cooling
* OS
* a OCCT / Prime95 Stable screenshot


I need Copy-Paste information

BTW, gsk3rd, did get ur pm, just didn't have the time to respond correctly...

Anyway, if your submission did not end up on the list, repost and I'll update.

Hey guys long time no chat. Summer time is finally gone and temps have been amazing! It's finally coming winter and I'm back to overclocking my 940 to see where the max ceiling of this chip is.

To recap, the farthest I went with an OC was 3.5ghz @ 1.425v with 220fsb with x16 multi. I have the CPU/chipset voltage bumped up to 1.25v.

I am currently attempting to get 3.7ghz stable with voltage increases but right now I'm not having any luck. To my surprise though it booted right into Windows with 1.425v. But upon running Prime95 my computer froze.

I bumped the voltage up to 1.435v and worker#4 failed almost instantly. So I bumped it up to 1.45v and worker#4 failed again... so I bumped it up to 1.4625v... and again, worker#4 failed within seconds. See a trend here? It's really kind of annoying that #4 goes so fast but worker#3 failed as well after a couple of minutes with the last 2 voltage bumps. I assume the voltage isn't high enough to keep the OC stable. So I'm about to reboot with another voltage bump to see where that takes me.

EDIT: 1.475v was a no go as well. This time worker#3 failed after a minute. Longer than the last times. Which tells me the OC is starting to become stable with voltage increases. I'm hoping the next bump can last a bit longer...

EDIT: 1.485v failed after a minute. I tried then running large FFT's and it failed right away. I'm running small FFT's and it's doing fine so far. I'm wondering now if my RAM is the culprit. I have it overclocked to 440mhz with a 220fsb because it helps out with my low HT link being on an older AM2+ motherboard. But I'm thinking if I remove the fsb OC and the CPU/chipset voltage bump and just work with the multiplier I might see some different results.

EDIT: Well dropping the fsb back down to 200 and working with the multiplier didn't net any different results. I have a feeling I'm going to have to push beyond 1.5v to even try and get 3.7ghz stable.

Fossil, go ahead and drop the memory divider. At this point you really don't need to overclock your memory. For all we know this could be causing your stability issues.

Do you know what your NB Frequency is currently at? How about your HT Link speed?

Good luck

With my 3.3ghz OC and a 220fsb my HT link is at 1100mhz and my NB is 1760mhz.

I stopped testing for stability until I got some advice on what to do because it seems like upping the voltage isn't doing anything.

I thought dropping the memory divider like you said might do it but it didn't seem to do anything. 1.4725v went over a minute and failed. Then I bumped it to 1.485v and it just crapped out on one of the cores almost right away. It did just this all the way from 1.435v. I'd think I would be noticing small gains with more voltage but nothing.

Fossil, everything looks great according to your post above. By any chance do you have "Spread Spectrum" enabled in your bios?

What overclock is actually stable? Can you post some CPU-Z screen shots (cpu and memory tab) of this stable OC? If I remember correctly weren't you the one having severe troubles overclocking your 940BE? I can't imagine your 940BE being that bad of an overclock but it is possible.

Good luck
