AMD 965BE 4.0Ghz. What else? - Page 2

post #11 of 70
Thread Starter 
Yea, I plan to keep this chip and board and add it to a dedicated server box. Best board and CPU I've had in a while, and it'd be a shame to get rid of them after they treated me so well.
I expect to get 4.8Ghz off the 2500k and that's what I'll be happy with. I've got the Japanese model H90 with duel 90mm cooling it. My Resa will follow a couple weeks behind. So should be pretty sick soon.

No. You can send as mutch as 1.5 - 1.55, same as cpu. Results in quite more heat... But it is not dangerous, or so everyone witch seems to have an actual understanding of amd agritecture.

Try 2800 whit 1.4 - 1.45 :-)

I'll give that a whirl after this round of testing. Not giving prime a 12 hour session. But I'm doing 15 minute rounds and then tweaking. So I'll give it a whirl.

But remeber that if you add more cpu nb voltage, you get more heat, and more heat can cause instability on your 4GHz oc.

I tried to increase the CPU/NB to 2800. I tried Volts 1.4 to 1.47v and I never could get the system to even boot.

I understand more volts more heat. Heat is not the issue I have yet to break 57c on prime95.


I tried using both CPU/NB volts and NB volts, and neither really made a difference on boot..Could it just be I cannot boot with that speed?

I have read that some of the chips get stability problem when holding 60+, and raising your cpu nb voltage would prob. make you hit thouse numbers if you allready at 57-58

So you could not boot whit cpu nb on 1.45? I am quite the noob, but i have read mutch about this arcitecture last few months, and my ques is that you have reatch your limit then.

I dont think raising your nb voltage will help either, but im not quite sure

Edit: Humor me and try to boot at cpu 3.6GHz and cpu nb at 2.8Ghz cpu nb v. 1.45

The temp on boot would never reach 60c+ It always boots at sub 35c so it should atleast boot.

Though will be kinda sad if this is as far as the girl can go. She's been a trooper of a chip..haha

Hehe, i wasnt thinking about when you was booting, but in prime cheers.gif

4GHz was also my limit on the 965BE,and the max i was only able to get on the cpu/nb was 2750. no matter what voltage i couldnt get it to boot up either. so i settled at 2750 1.3v. In order to get there i think i used an FSB of 250 and bumped up the cpu/nb from there, left the HT at 2000. I also used the multiplier and manually set the cpu/nb but went back to using the fsb as it gave me better results. also i left my ram at 1333 and lowered the timings, at 1600 i get a lot of instability. I hope this helps i am kind of new, if i said anything dumb please dont hate lol, just trying to help.biggrin.gif

This sucks..lol I was hoping I had a little more play. Or that I was still a noob at overclocking. Seems I am better then I thought, cause everyone is saying pretty much everything I've tried..Oh well..Was fun well it lasted..haha
