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

[Alcibiades]

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.

Thanks T_M
Will do with the VTT
Highest I tried was VTT=1.62 and PLL=1.4 so that's my problem right there
I was doin' MCH 1.5V manually trying to get 500-600FSB
My first time on a DDR3 board

The OCZ PC3-1600 Platinums are rated @ 1.8V for 2000Mhz
Auto gives 'em 1.96V @ 1500Mhz
So they probably need 2.1V for 2000 at that rate
Is that safe 24/7 longterm? electromigration?

Anyway I don't want to give the DDR's more than 1.95-2.00V MAX
but next time i get a chance i'll go for gold!

This thread has details of the sky high kind of volts i was pumping, and never killed that E8400.
Depending on your RAM, 2.1V is quite common voltage to use.
Ive been running 2.1-2.15V on my sticks ever since i got em.

I know my friend, I've read the whole thread
If the system was mine I would be there with you guys, pushing
but it's my OLDER brothers PC and I have to be veeeeery very careful
He goes OFFFFF if the system crashes during his WOW adventures
Thanks for the feedback T_M

Can someone tell me where i find these settings in the bios?
VTT , MCH , MCH ??? will be holding your FSB potential quite a bit.
and what do they stand for??

Noowby all over this board sry , i come from a 790i Ultra

THNX Greetzzz

[T_M]

VTT = Termination Voltage
VMCH = vNB = North Bridge Voltage

AAAA i see can somone plz give me the latest BIOS to i have 3Fc but the mobo will only boot with my ram way dow to 920MHz or sommething

is there a F4 bios or a good F3 there?

thnx Gys geart help here

After having toi RMAS my Cellshock bllue , am finally getting to play with my
Gigabyte GA-EP45T-EXTREME, coming from the ddr2 Extreme I'm surprised to see the differences between the 2 boards. In particular the omission of CPU GTLref altogether seems weird.

Anyone any takes on why ??

[Nanok]

Soo damm close to fsb 700.

When they put CPU Reference in the bios the board gets unstable.
They are working on it.

Prime Q9650@Extreme.

Great thanks , it really seems strange the DDR2 mobo was as sweet as anything ocing cpu I basically set it once & thenn left it to scale with vtt, it was rock steady.
So far not seen much difference , but had to add a notch of MCH over what ran well on the DDR2.

Hey guys, Alcibiades was nice enough to invite my over here( thanks pal). I've been having trouble going much higher than 4.8. I've gotten pretty stable at 4.3(430X10) but I've been trying to do a few suicide runs and I can't even make 500FSB(500X10) even with massive volts. Here's an example, here's my settings.




I can barely get into Windows, but I can't even open CPUz without BSOD. I even loosened my RAM timings to 9-9-9-24 and it makes no difference. Could it be my RAM causing problems?
Conversely, I'm prime stable with these settings. ( except MCH reference which is 0.76, This changes whenever I change CPU PLL, is there a connection between these 2?)


Am I missing something? Can someone help? I'm wondering how someone can get this high with under 1.3v and I can't get within 1000Mhz with way more volts.

[Benny Lodewijk]

@ x2s3w4 : first try to setting all AUTO in BIOS..the only thing you change is FSB.. and see if any difference. FSB 500 is really easy with this board, and i can get up tp FSB 550 stable with all AUTO setting.

You really think that this is real V ? NOT, CPU-Z's old-known bug.

[BulldogPO]

Dudes, any word on newer bioses?
And can someone measure size of those NB cooler screws, I lost my scrows somewhere

Uuuuhhhh....... I guess you got me there with the voltage. I am on air cooling though. Most of those guys going higher with vcore are using LN2/phase ect though. Vdroop/vdrop seems excessive also. I set it to 1.4 in BIOS, in Windows it drops to 1.36 and under load it's 1.328. Seems like a lot. Any mods for it?
I'll try using auto everything.Thanks for the input.
Edit: Oh, are you saying that CPUz reading wrong is a bug? I hadn't heard that. Thanks for the info.

[Supershanks]

Any mods for it?

see top of previous page

Alright, I wasn't able to get to 5GHz no matter what I do. I tried everything on Auto. I wasn't able to get higher than 4.4(440X10).
I also tried bumping the voltage to 1.88 and still couldn't get into Windows. However I was able to get up to 575X6 on all auto voltage. And 8.5X525, although I didn't get a screenshot of that. Here's the 570, it seems weird that auto tightens my timings.

5 Ghz on air is not always eays m8

[dinos22]

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.

i just noticed this little hint
eeeeeek
gotta hit the labs in Taiwan with hicookie to see this little beauty in action

good to hear man

BenchZoner is doing some insane volts as well but constantly stressing his 5 different rigs and after a month now not a single dead CPU yet

F4b with CPU Reference and MCH/DRAM Reference

Also:Improve DDR3 overclocking up to 2200MHz

click

Scroll complete down and look for the P45T-Extreme in "Bios Downloads Auswahl"

[BulldogPO]

Great!

Oh good news was missing the gtlref

Improve DDR3 overclocking up to 2200MHz

Assume there are now some profile options rather than just auto

Thanks

[Supershanks]

Anyone else flashed to F4b ok ??
Watching liverpool v marseille so flashed at half time, just get a repeating led sequence C1 C3 02 88 (or 8B)
Will look again later 2nd half is on

[Supershanks]

Good news Liverpool won
Bad news still in loop.
Tried
Recovery for F5A on X48T but not with battery removed. Can't be arsed to wrestle battery out tonight will try tomorrow. Doesn't look good.
