Ok so I should go in and knock it down to 1.4 at least ?

yeah, that would be an idea... sometimes less, is more
have you ever tried how low you can volt the proc at stock clocks? that would a be a good point to start i guess

Thanks for your help VW. Everything is cool as cucumbers now and running at 20C idle.
No hot spots at CPU is and 3520.0 GHz. My dumb ass finally figure out how to adjust voltage.

 

[de.das.dude]

then do what I and many others do, place a fan towards the vregs and such to keepem cool.

that would mean a fan above the CPU area, thats a bad idea as the fan would mess up the CPU's fans flow and create turbulence, not to mention there already is the exhaust fan at the back.


its easier to put some copper heatsinks on them and let the exhaust fan at the back take the hot stuff out.

Doesn't matter if your water cooling your CPU.

I. AM. BACK. WITH. MY. CURRENT. PC !!!!!!!!!!!!! F*** YEAH !!!!!!!!!! Anyone of you remember my promise to either post 4.0+GHz OC by tomorrow, or - more realistically - by May ? I deliver. BTW : if any of you Mods (Mussels, erocker) can - please change my account/nickname to YautjaLord. Much appreciated, stay tuned.

P.S. The CPU is 965BE rev.C3 125W TDP (Checked the CPU-Z & it says the CPU's TDP is even 124W. Did the CPU-Z lowered 1W for me ? ) Stay tuned.

like i did brad if u seen my 120mm fan

it seems velet is the only one that can understand what i am saying

exactly cause the vrms will got hot not matter how good the cpu temps, of course thus the lower the cpu temps thus lower the vrms temps will be

 

[erocker]

Corduroy, use the multi quote button. I shouldn't need to remind you not to double,tripple post again.

i have tried anything possible with my 955, with 3 different boards...volting down, then clocking up seemed to be most sucessfull

Ever since I got it, this is actually the first time I've overclocked this CPU. So far want to see what default voltage can do:

this on default voltage? OMG

Well.. many motherboards will scale the voltage up when set on Auto. Then again some boards will run AMD CPU's at 1.4v at stock no matter what. Not a problem.

 

[crunchie]

Mine is stable 4Ghz with 1.344vcore. Runs 1 hour Prime and games fine at that. Under water.

 

[erocker]

That's extremely good! Go for my ghz with that chip, it will make a difference.

 

[crunchie]

Have validated @ 4.5Ghz with 1.52vcore. Benched @ 4.25Ghz with no problem. I have a mental thing happening with running it 24/7 at that frequency though. Been happy with 4Ghz though and it runs great at that.

 

[erocker]

Yeah, very nice chip you have there. I've run mine at 4.2ghz 1.46v 24/7 since I got it.

 

[de.das.dude]

my mobo sucks. the mosfets dont even have heatsinks. so voltage fluctuates..

Only four chokes on your board and a 4 pin CPU power connector. Heatsinks aren't going to fix that.

That is full load (crunching). it sticks to that voltage under load.

 

[de.das.dude]

mine is going all the way from 1.32V to 1.38V and back continously under load.

EDIT: plz explain how more chokes and an 8 pin CPU power connector can stabilize voltage

can split the current load over more wires (8pin) to provide (more phases) cleaner power.

chokes are high voltage filters, and 8pin means double the electrical conduit to you board opposed to what you have now

what if i make a high capacitance ckt and join it across the two(separately of course) 12V rails feeding the 4pin input of the CPU power?

 

[JrRacinFan]

You are still feeding over 4 wires attached to the board.

of course, if youre electrically versatile, you can solder additional 12v inputs and grounds on the backside of the board (where the 4 pin and the 24pin connects), to which you run molex plugs from the PSU (opposed to buying a new board). i did it myself once, and it helped a little in supplying an old p4 board better than before
Capacity wont help you much i guess... capacitors need to be as close to the pcb as possible so that they dont produce so much electrical noise.. which wont be too easy to be done on the backside

buying a mobo is no no. we are going to some really hard times. hell my monitor(14" CRT) died last and i had to spend my whole morning fixing (and simultaneously praying to God) . darn electrolytic capacitor had leaked
yes im electrically very versatile. just finished making a custom temp sensing thermal controlling ckt for my 2 GPU fans. need to make one more for the over all case temp.
