People! I could achieve 4ghz 471x8.5 with 1.37500vcore (bios) 1.344 cpuz, and lowering!
But I would like to know what you thing about LOAD LINE CALIBRATION (LLC), because I got it Enabled.
Later I will show you my settings.
And... OC NUB thanks for your help, there was others users who helped me, thanks!
The problem was on the COMMAND RATE, it was auto = 0 in my settings, so trying to do something else I have changed it for 1 and just like magic It got stable.
i keep LLC enabled too.Quote:

If it is working don't fix it, but normally the MCH reference should be 1 or 2 notches up from the cpu reference. With 1.20v CPU termination I set the CPU reference to .760 or .785 and the MCH reference to .800 then raise the CPU termination as needed.
So I should put CPU REF on .760 or .785 and MCH REF on .800, and then reise vtt without thouching those REF settings??
And always keeping mch ref 1 or 2 notches over cpu ref..
??
That what I do, the ref's will increase automatically as you increase the vtt. start out with the vtt at default-1.20, set the refs .760-.785 cpu ref and .80 mch ref. then raise vtt but dont raise the refs after that. Those two are linked to the vtt.Quote:

Same here, I use LLC too
Got a sub 10 sec pi

Nice! Congrats! You got a nice batch dude!Quote:

Can you please help me figure out these issues?
My systems specs are in my signature.

Hi BuGjAE, nice to see you here againQuote:

i think your new board probably worked better than your previous one.
Thanks xzulu.Quote:

Nice coop!
Coop,very nice score:up:
pangingIII,awesome OC on your 9550:D
well i took matters into my own hands.instead of waiting to buy a new true,i
figured out how to mount
my mini-typhoon on my cpu.i had to file down the corner,cause it was hitting one of the capacitors
(it mounts from corner to corner).but it paid off:D
15c-20c drop in temps:up:
this exact same OC,the temps were hitting 65c-67c and i had to stop it.
but now as you can see temps are great
http://i39.tinypic.com/2lapno8.jpg
i might be able to run LinX or IBT now,maybe:rolleyes:
Nice temps radaja.
Was able to get vcore down a bit. Just before posting this I got a bsod at 8hrs 5min Ortho's while opening everything up to take a ss :mad:. Took this ss earlier this morning.
thanks.i kept putting off modifying the mini-typhoon cause i never thought i would get these kind of results.
when i had the intel stock cooler with the 92mm 4500-4700RPM fan on top blowing directly down,i didnt think
the little extra surface the mini-typhoon had would make much of a difference,but it's all copper and has six
pipes,so i guess it really does make alot of difference.
by the way nice OC
thanks.Quote:

Great job PangingIII with your 9550.

well heres a comparison with my new cooler setup.
the first one i had to stop at 8m cause the temps hit 67c
http://i41.tinypic.com/2v9u6qa.jpg
and now it never goes above 50c:D
http://i40.tinypic.com/on61i.jpg
Doesn't look like you even need the Ultra 120.
nope.:D
thats exactly what i was thinking.
xzulu, oc nub, radaja, thanks. It used to take twice as long even with dry ice for 32m. I did that so many times,
I think it did something to me:nuts:
radaja, that is a great relief I'm sure. excellent payoff for a little work. pangingIII, really nice job.
