Phenom II steppings and max OC 550-940 - Page 196

Ben, wow 42C full load! I guess that explains why you're running a Delta fan. Aren't those fans so awesome? I have a 120mm at home and it sounds like a vacuum

Good luck with the 4Ghz run

When I first plugged this fan in it almost flew out of my hands lol.... I just can't beleive the difference lol.


Update for 4.0 stable....19 min left ( the anxiety is a killer ) this has been the longest i have made it.

EDIT : Uggh lol...It died with 14 min left...But it didn't blue screen, means I am real close

Oh well I will try it again a different day.

After playing with this all day, I have finally conquered 4.0ghz OCCT LinPack stable

Due to a weather change my ambient temp dropped from the usual 72F to 62F

My idle temps from my 3.9 stable SS to my 4.0 stable SS reflect this. So I present this to you.

Phenom II 940 (Lapped)
Stepping: CACVC AC 0850EPAW
Revision: RB-C2
Max Stable: 4000.0 mhz
RF + Multi: 20x200
Vcore: 1.525v
NB Clock: 1800.0mhz
HT: 1800.0mhz
HT Voltage: 1.35v
Foxconn Desroyer 780a
Bios: P14
Air Cooling: T.R.U.E (Lapped) w/ Delta (151.85 cfm)
Vista Business 64bit SP1



I have been using the 4.0 stable OC since 9:38pm last night and decided to do another stability test using OCCT LinPack again...this time on the Max setting.



Not once has my Comp crashed or has had any problems what-so-ever

Although I have deemed this stable, I am going back to my 24/7 settings...as there is no reason to run this at 4.0ghz w/1.52v. I have accomplished what I set out to do and am very happy:

Hey fellas I just got my 940 yesterday and have been messing with it all night/day. Funny thing is my BIOS reads the CPU voltages somewhat correct as opposed to my older BIOS version and my brisbane dually.

After making sure the chip was fine with an hour test I bumped the HT up to 220 on stock voltages and ran it over night. 6 hours stable and was still going, but I deemed it fine and I've been tweaking the settings trying to get 3.5ghz stable most of the day. This is what my runs have looked like for the most part.

3.3ghz @ 1.36v, HT 1.20v - 6 hrs orthos/prime95(3 instances) stable
3.5ghz @ 1.385v, HT 1.20v - 6 mins failed
3.5ghz @ 1.385v, HT 1.25v - 30 mins failed
3.5ghz @ 1.40v, HT 1.25v - 1.5hrs failed
3.5ghz @ 1.41v, HT 1.25v - 3 hrs failed
3.5ghz @ 1.41v, HT 1.30v - failed almost immediately. My computer actually locked up(first time)
3.5ghz @ 1.425v, HT 1.25v - 4 instances of prime95 blend running strong for about 30 mins so far. I have a feeling this will be stable.

Here is a screenshot of what is currently running in the background. Yeah I know the temps are a little scary and it sucks, but I can't do anything about it. Arizona summers are a pain in the ass and the cooling in this house is not at all sufficient. My dually was idling around 32C before I took it out. My 940 was right around 38C idling. So under cooler conditions my load temps would probably be in the low-mid 40C's.

That's exactly the vcore to run mine at 3510mhz, althought it's really around 1.425-1.475v because of overvolting native to my board.

Mine might actually be overvolted as well. BIOS gets slightly off the more I push the voltage. I think setting it at 1.425v it reads as 1.44v in the hardware monitor.

So far all 4 instances of prime are rock solid going on 5 hours.

Ben, great job on the 4Ghz stable overclock

Fossil, those full loads actually aren't too bad considering how high your ambient temperatures are. If you really think about though your machine probably won't be seeing those high of temperatures that often.

Good luck guys

True true. I'm going to let prime95 run for the rest of the night and if it passes 12 hours I'll call it stable. 3.5ghz is what I was aiming for a minimum overclock. I'll probably test push to see if I can get 3.7 or higher depending on how the ambient is the next few days. It's actually 65F outside right now so my load is hovering around 51C on the Phenom.

Fossil, 51C is not bad at all

Are you sure the Zalman 9700 will be able to handle any more vcore increases?

Good luck
