[Team.AU] Gigabyte GA-EP45T Extreme - P45 DDR3 Monster

[hicookie]

someone got vdroop mod for this board, could be nice for 3d06 single?

ISL6336, from this layout, FB is #16, Vdiff is #17
give a resistor between this 2 pin, you can fix loadline calibration

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.

great info in the thread hicookie

Deanzo far out man 700MHz FSB dual channel and dual core

post your settings so that others with the same board can try

[Gautam]

702FSB Both Cores and Dual Channel.

Theres more in it, just got to work out the right combo.

DeanzOWN!!

yup, all GBT EP45 use same IC.

Thanks mate, to save/keep cpu-z open past 668 I needed to change the stock cooling
And then used the same settings (nice when that happens) but I only had 3lts on hand, so it was a very fast test.

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




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

[dinos22]

nice man
so cooling helped

where'd ya get the NB pot?

Very much so .


I ordered it off Duniek. It's his Rev3.0

[BulldogPO]

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

lol...am i tired.., okay need to fix the picture to 5k, you also can use 50k, with 5k
get better turning vr to 1.5~1.8k for cpu vcore loading.

[boostedevo]

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

just remeber Pin#16 & 17, GBT's X58 use same Ic
you can figure out it quickly a vdrooping mod on x58
alternative way by #16 you also can make a vcore mod.

Thanks hicookie, my board needs this mod.

Dudes, have you tried F3j bios?

[Planet]

Any list of fixes or anything?
Still getting locks at 600 FSB

[antoine76]

Dudes, have you tried F3j bios?

Link of this bios please ?

[jooney]

Here is F3 Final,its a advance Version.
click
Scroll complete down and look for the P45T-Extreme in "Bios Downloads Auswahl"

[redratamd]

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

[boostedevo]

3:5 ratio/400 strap (3.33D) doesn't read correctly.

http://www.xtremesystems.org/forums/...d.php?t=199241

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.

[BulldogPO]

Does your boards boot with 266 or 333MHz strap?

[M.I.K.E.Y]

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

[Alcibiades]

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 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.

[T_M]

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.
