prepare a 5kohm vr, connect to Pin#16 & Pin#17
using meter to measure it , oringinal should be 45.5k
turn it to 1.5~1.8k, depend on what loading.

Hicookie
great info in the thread hicookie :up:
Deanzo far out man 700MHz FSB dual channel and dual core
post your settings so that others with the same board can try
:up:
DeanzOWN!! :up:Quote:

After taking off the stock heat pipes, I found they were not making good contact with the fets.

But thats an easy fix with some after market coolers :D

All up and running and gave me an easy 700 FSB with out too much work!

I'm at work now, I'll post up my settings a little later :)
nice man
so cooling helped
where'd ya get the NB pot?
Very much so ;).Quote:

Does that LN2 on NB help that much. Wow.
I think that I will try larger heatsink on NB, or just reseat std cooling.
hicookie, I noticed that you typed "5kohm vr" in your text, but the graphic shows 50k ohm vr ;) Just bringing it to your attention in case you want to fix it :D

50K = a lot more turning for the same results :D Thanks for posting the mod BTW :cool:

alternative way by #16 you also can make a vcore mod.
Thanks hicookie, my board needs this mod.Quote:

Any list of fixes or anything?
Still getting locks at 600 FSB
Link of this bios please ? :confused:Quote:

click
Scroll complete down and look for the P45T-Extreme in "Bios Downloads Auswahl"
Thx . ;)
I've tested F3I & F3J ,F3J is better for the ram up. I boot @ FSB : 630MHz ,Ram
1050MHz ,Extreme , 7-7-7-24 others on auto (it's give PL 11) ,i can run Spi 1M @ 637Mhz .
I test the final version soon.
same as yu with the F3 final ;)Quote:

I seem to have no better luck with F3 final than I have with any other BIOS where mem is concerned. Mem maxes out around 980-990 on CAS 7. CAS 8 goes over 1000 easily, but CAS 6 also seems to be stuck ~880MHz max.
Does your boards boot with 266 or 333MHz strap?
Sorry if this is a nooby quistion , but can somone plz give me some hints ( V-core, divider, pll, etc...) for oc this board with a qx9650 and corsair 1600 MHz cl7-7-7-20 t2 plzz ??
I can get to 4Ghz but ram wont run standard and i want to hit 4.4GHz with ram @ 1600MHz if possible?
I have good waterkoeling ;-)
sorry for bad language i am from Belgium.
thnx for the help gys
If RAM is holding back your overclock, adjust the memory divider to slow down the RAM speed
Visited my brothers EP45T-Extreme yesterday
After 2 hours of failed o/c attempts...
Auto settings for all voltages on a mild? overclock gave me this:
PLL from 1.5v -> 1.76v
VTT from 1.2v -> 1.50v
DRAM from 1.8v -> 1.96v
I'm trusting that gigabyte bios knows what's best :shrug: and safe
The board's LEDs show only the DRAM to be on high (red) overvoltage
Should I be worried with any of these settings?

When I have more time I intend getting his 2GBx1 OCZ PC3-1600's running at 2000 or that's the plan at least.
It's interesting to see what the board does when left on auto
not just for the pll, vtt and dram voltages,
but notice how it drops MCH ref voltage from 760 to 660
maybe that's why I was having troubles with the higher memory speeds, I kept the MCH close to 760 default
Would be interested in seeing other's bios setting, this thread is a little short in that department.
Those Auto voltages will be safe enough from what all other users are experiencing.
We havent had a reported death yet from Auto's.
I would suggest you even try some higher manual values, like VTT = 1.7V, MCH = 1.5V.
MCH = 1.2V will be holding your FSB potential quite a bit.
