2 - 1hour tests using OCCT Linpack (One on the Max setting, and one on the mem setting) with an ambient temp of 62F.


It was really a chore to finally get it all right....The toughest part was getting the ram settings correct ( to make a happy IMC ) and using Vista 64bit made it even tougher.

In the end I accomplished what I set out to do (am happy about the out come) but that being said..... With summer time temps and air cooling it's definantly not something I want to run all the time and it's only used if I feel like benching ( hardly ever ).

If the ambient temps drop I plan to do a 10hr run....some may wonder why I don't do it now....and my reasoning is my own ( My CPU has never been above 50 C and I would like to keep it that way...Sounds funny I know, it's just my preference)


Anyways I Look forward to your results


Don't be a stranger lol
Not only is that a very impressive OC, a good post, but a quick response as well! Thanks and +rep to you sir.

Very glad to see such results, gives me hope. And like you, in my situation it would also seem that the memory can be quite a problem - to get 3.9ghz @ 1.5v I need to play around with my clock skews a lot. And as anyone can tell you that is... that is not fun at all. I managed 3.9ghz under several different configurations without having to adjust my clock skews, however that was all with higher v cores (1.52 and 1.54 iirc - I posted them somewhere in this thread).

And I understand what you are saying, with regards to not wanting to go above a certain temperature. At the end of the day, 4.0ghz is not that much over 3.9ghz in terms of performance - its more of a goal that people try to reach, an elusive milestone for AMD quad cores. For most 940 users, even 3.7 or 3.9ghz is not worth the additional temps over a lower oc.

That said, I have not tried any extreme overclocking with my new setup yet so it should be interesting at least! Depending on what my temps are however, I may just stick at 3.9ghz for long term use.

Edit: Man, I'm forgetting my manners - I forgot to add, very nice OC's Robbo2, Gerikoh and Biggums!

Hey Drin, nice to c you back here.
There indeed have been some impressive stable OC's.
Hitting a stable 4GHz is a goal for me too, but I can't seem to hit it .
I invested in watercooling and TEC's, load temps hitting only 36C on 3.7GHz with 1.47V, but 4GHz seems to be a no go even with load temps only at 43C.

I hope you will achieve your goal and maybe I can learn from the settings you used, as I'm out of ideas


As for the CPU-z Validation Only, as soon I figured out how I can add links in google documents as in excel, the list will be created.

Do you guys think the 3.8 - 4.0Ghz overclocks are dependent on the stepping of the processor? Could it just be a hit or miss? The same kind of thing applied to S939 with the LCB9E and LCBQE steppings. Some 9E's and QE's could overclock like crazy and some just didn't have it at all...

I have no idea...I do know my 3.913GHz OC is quite high, looking at other OC's.
Don't quite know which stepping XxBeNigNxX has, but his 940 can hit 4GHz no sweat.

I think I'll swap my Kingstons with some OCZ mem, maybe that'll do the trick....

Hi everyone

I have 2 Phenom II 940's for both of my main rigs, the Steppings are:

Foxconn Destroyer build: CACVC AC 0850EPAW <---in List


Foxconn A79A-S build: CACVC AC 0852GPDW

With the A79A-S I have not been able to get a Complete run of OCCT @ 4.0ghz (made it 52 min with the A79A-S).

Summer started to come and I said not again till fall.


So for the Question asked by thlnk3r:

I don't think steppings really have much to do with the OC, but I think the position in the wafer that they came out of does (but I could be Dead wrong). Some Chips OC higher than Others.. and some less.

Alot comes down to the CPU itself....but in order to get the most out of the CPU every component has to get along
