Phenom 9850BE low voltage overclocking results!

I was thinking of doing that too along with manually lowering the HT link.

At least I can now say that proudly that my rig runs at 27°c idle and 49°c under load.

that feels much safer doesn't it lol. another BSOD and bring your HT back to default 2.0 GHz, and bump vcore to 1.3 that should do the trick.

I feel much safer with those temps and a load off my back too. It was so puzzling.

Sounds like a plan . I think I might even raise the FSB to 250 as well. Or would you recommend I toy with the NB multi?

a small increas in CPU speed wont hurt, if its stable then, try your NB multi after

...yawn... ram is good.

EDIT: Ooops...damn. Shows I just woke up?!?!?!? I guess I should have taken the screenshot before I stopped it eh? Well it did 10 passes, %1000+ and no errors. Yay.

theres some relief to ya. So how has the rig behaved?

Well, things are different now. I haven't had a BSOD. And things are all stable at 3.0. I lowered the HT link to 1.6 in the bios and it's now running at 1920Mhz. Haven't had much time to up the FSB any. I tried to go 250 but everest only lasted 2 mins before going red. Maybe not enough voltage??? I tried it at 245 as well and same thing. But it's fine at 240.

GOod. How much voltage at 240?

When I ran the 12 hour stress it was set to 1.275 for both vcore and cpu-nb. Now I have it at 1.3 for both. I tried 1.3125 to up the FSB to 245-250 and everest still went red after 2 mins. I have ACC at 0% in Bios and vdda still at 2.5v I tried auto express off and no difference. Maybe if I lower the ram to 667. I dunno. I think I might just be happy with 3.0 stable. I will be picking up the PII 940 in a few months anyway!

you will need about 1.32-1.36v for 3.1 GHz stable.


However im sure at 3.0 GHz it is more than enough for what you do

Yeah but it's also fun to achieve just to brag


Yeah, I figured i'd need the voltage to be higher for it but didn't have the time nor do I want my temps higher than upper 40's under load. My HD3870 is happy as a pig in mud at 855Mhz with the Memclk @ 1201Mhz. HWmonitor never shows higher than 65c max for GPU after playing UT3 for an hour or 2.

i think it is setup sweet. its a good overclock and you'll enjoy it.

I upped it to 1.750Vcore and I got this:

Now I'm totally confused

 

[Chicken Patty]

wtf, what do you mean thats what you got

 

[ChaoticAtmosphere]

I'm being facetious...lol. But seriously, I tried to up the voltage and It's not going to go any higher than 3.0Ghz. 960Mhz for Mem. As you said CP it's a good clock and only took me a little over a month to achieve it. I'm staying put now. These Phenoms are certainly touchy but once you find their sweet spot they are definitely solid.

I think I'm going to sit with a balance between Kei's philosophy and the hardcore OCer. You were right CP. I got to 3.0Ghz at 1.3vcore and it's stable. It was almost like a prophecy by you ...lol.

Had fun playing with it and I'm looking forward to the PII 940 later this summer.

lol, yeah I these CPUs are so good when the find the sweet spot, but while your at it, they make your life miserable

Well the reason why I told you the voltage you needed was because bro, I have been oveclocking for about a year from scratch. Bro but in that year I put sooo much time into it that by now I can say I pretty much no my way around these Phenoms as good as some of the top overclockers. Of course give me some ln2 and I probably wont go anywhere since I've never overclocked with LN2, but on air and water your normal everyday rig, I consider myself to be one of the most knowledgeable people on these forums, I have lots of first hand experience overclocking these CPU's.

Gladly you've been listening to from the beginning along as you have to some of us in here who have been great, and I myself have learned tons from them

Haha! Well it seems everything is just right!! I wonder if that statment applies to the Phenom II's!!

PII's like lower volts in my findings CA

I dont know, no first hand experience yet, sorry

45nm, they better

 

[fullinfusion]

well Kei, you like to under volt and under clock...... hows this? it should save the hydro bill and keep the tree huggers happy hey.

 

[Kei]

Hahaha, I was curious one day to see if it was possible and what it would look like so I did the ridiculous clock shown below. The Northbridge was at 2.0Ghz, HT Link was 2.0Ghz (4.0Ghz actual speed) and the ram was 1000Mhz cas 5.

The everest results were amusing

I was going to do a full suite of benchmarks for fun, but the everest run took so long I changed my mind hahahahaha.

lol i knew that i would get your attention
Hey i ran Wprime and it took 46sec.... Mark06.... well lets say i didnt wana wait but the 1st test was showing 25fps and droped to 10fsb.... so needless to say i didnt have time to waste... I also just removed the radiator off the bace of the case and shook it like a mad man and low and behold.... a heap of air bubbles purged from it into the rez..... temps @ 3.88GHz are idling at 28c now..... sure beats the 38c before...
I had the cooling lines off a few weeks ago and an hour after letting it run i shook the rad and a few bubbles purged so i thought it was fine, but it does take longer.... i just found that out....

^^^ thats crazy how low you guys clocked those CPUs wow!!! I bet you will love your electric bill

Yeah CP but my gpu sucks power like its free!!!! it almost need's its own power grid to run lol....but here in the land of ice and snow the hydro is really cheap.... like 60 dollars a month in the winter, and the same in the summer running the air-con 24/7
Hey Kei?
You know alot about the PII's.... can you help me here... Pleeeeeeeeeese?
I need to know, in the bios what should i set the cpu prefetching to.....i know what it does but does it apply to AMD cpu's? and also the micro code validation....what the hell is it? and what is it for? i believe that's what its called.... any help and explanation would be greatly appreciated mate

its own power grid lol.

i got my 2nd 4870 on the way, lets see how my elec. bill does!
