Phenom II steppings and max OC 550-940 - Page 121

I hate to ask this because I sound like I don't believe you all but how many of these 3.9GHZ + Overclocks are actually prime stable? The reason i ask is my 940 won't go over 3.5 Prime Stable, but I can boot into and use windows up to 4.2GHZ.

I have tried everything from Higher volts to lowering Ram and NB speeds. I have rasied every voltage there is, it just isn't prime stable.
Well, I achieved 3.9ghz OCCT stable under three different configurations, two of which were rock solid (I consider rock solid to be 2 passes of 1 hour high priority OCCT, prime for 4 hours, and of course, a couple of hours of TF2! ). The last combination I used for 3.9ghz which was one hour OCCT stable, crashed the second time I did an OCCT stress test, so I did not consider it stable and did not post it up. I posted images of all my stable overclocks somewhere throughout the thread, and my best current one is in my sig. I always have the logs to post if anyone doubts them anyway I prefer to use OCCT, since it discovers errors much faster, and it's generally considered that one hour of high priority OCCT = at least two-four hours prime stable. It's my personal preference, but I tend to not like posting suicide/CPU-Z valid only screenshots.

I understand the need for, and appreciate, those people who push the envelope and bench on suicide runs, it is important and shows the potential of a cpu, as what was once unstable may become stable through future bios updates etc, etc. Think about it this way, if people did not post them this thread would be a lot less interesting You just have to rely on people being honest, and I see no reason to believe that anyone is lying in this thread. In either case, you can always rely on those who have posted evidence of it being prime/OCCT stable.

And it's always important to note that in reality, you can never get any system 100% stable. Sure you can eliminate the risk of an OC related system crash to near impossible levels, but you can never completely remove it. So in reality, what one person deems to be stable may not be satisfactory to another, and it's difficult to determine what exactly constitutes a 'stable' overclock


Anyway, I decided its about time I threw my hat back in the ring I've been sitting on a broken cooling system for a month now, which is a joke. I was waiting for ultra kazes to become available again in Australia, however after a month of waiting I gave up. My Slipstreams arrived today, and I'm going to go out tomorrow and purchase the sandpaper for lapping my processor/heatsink. Combined with a new bios, northbridge and southbridge coolers, I'm pretty confident I will hit 4.0ghz. Probably will, but it's never a given. Hopefully if I'm lucky, I'll hit 4.1ghz stable on air, which to my knowledge has not been achieved yet. I'll video record any decent OC's to prove that it was done on air as well (probably going to set the minimum requirement to be 4.1-4.2ghz stable, IF that is possible).


With three days to test the heck out of my system, I'm taking suggestions for benchmarks, as I'm not sure what ones (if any) people would like to see. I'll do the standards such as 3Dmark06, 3Dmark Vantage and superPI. Let me know if there are any good benchmarks which I have not considered!

4.2GHz has been done, but wasn't neither prime nor occt tested and I'd bet it wasn't stable, so indeed if you manage to get 4.1 stable it'd be a first.

For the benchs, I'd run a small Crysis Warhead bench test as well as the standards.
If you're gonna toy with the FSB quite much, I'd also like a run of EVEREST's cache & mem benchmark to see if there's an actual difference, but that's just a personal wish.

you say you get air sucking in when you turn it up all the way? the loop should be closed. i.e. no air (or water) should be able to get in or out. try to identify where this "leak" is coming from and get back to us because having your speed all the way down on that pump is REALLY hurting your flow rates which isn't doing anything for your temps.
There is no leak as far as I can tell, the system has been leak tested for well over 24 hours. From what I can tell there is a small pocket of air in the top of the res, and when the pump is turned all the way up it some how draws the air from there. I have the Magi Cool 240 res, which I am thinking is maybe too small for the loop. I could be wrong but that is the only thing I can think of.

Thanks for the suggestions! This might sound silly, but do you need to own a copy of crysis warhead to use the bench? Same as for everest, but if I recall you can use a trial version.

Would like to try these out, and as long as they are not too expensive, I'll give it a shot!

Crysis Warhead Benchmark Tool can be found here at Guru3D

As for EVEREST Ultimate Edition, you can download the trial version on Lavalys' site by following this link

Crysis Warhead Benchmark Tool is free, and EVEREST Ultimate, well you've got a trial version with almost everything unlocked for you to test so
Personaly I ended up buying EVEREST at the end of my trial period because it gives me all the info I need about my comp that I need, and it's not that expensive in the end.

Btw, I have a 920@3.220Ghz (230x14) stable with a 1.35 vCore.(stock.)

I'll post some screenies+verification+benches of it later when I get home.

I will be dicing with the phenom II 940 Saturday. I've already prepped the foxconn board and hopefully will be picking up some dryice today or early tomorrow.

For some of you lucky guys who can obtain below 0 temps, don't be scared of the 200+c degrees being reported. 255c = -1, 254c = -2c, etc. Unless you get speedfan and it will report the IHS accurately. Well about as accurate as software temps can be at below zero.

I started to freak out when I saw cpu temp @ 253c+ with dice but then I opened OCCT and it showed all 4 cores @ 0c and looked at bios temp and that showed -60c+

I still have my board prepped in case I go for another run this weekend, good luck on your run..

I hope you get 4.1ghz stable. I had my cpu take the setting and was stable for 3 seconds at 4.1ghz.
