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

nice man
so cooling helped
where'd ya get the NB pot?
Very much so ;).Quote:

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

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.
Thanks T_M :up:Quote:

I was doin' MCH 1.5V manually trying to get 500-600FSB
My first time on a DDR3 board :p:
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! :D
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 threadQuote:

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 ??
Soo damm close to fsb 700.

Hey guys, Alcibiades was nice enough to invite my over here( thanks pal:up:). 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.

http://i244.photobucket.com/albums/g...Picture001.jpg
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?)
http://i244.photobucket.com/albums/g...Picture010.jpg
http://i244.photobucket.com/albums/g...Picture009.jpg
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.
http://i244.photobucket.com/albums/g...zzzzzzzzzz.jpg
@ 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.
:rofl:Quote:

I'll try using auto everything.Thanks for the input.:up:

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 :)
Good news Liverpool won :up::clap:
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.
Well It's tomorrow & it worked using sbenrap's method in earlier link.
F4B Changes Not done any clocks yet.
guys this board for me will not post if i set fsb over 400mhz :( hell might not post over 333mhz asit seems ive only got 333x10 to work
Ive tried right to 500 as some say oyu need ot work in fsb steps, but when ever i leave the bios it shuts down tries ot post and it cycles 3x's and resets defualts.
Ive tried 3 diff e8500/e8600's used higher than normal voltages and removed the cooling and I had perfect contact so i can only assume since Ive tried all the bioses that the board I have must be a reject :down:
1st gigabyte board for a customer build in 2 yrs and It doesnt work right feels like my first black ops same thing wouldnt do anything for me at the time people said you have to WORK the board compared to others, but on rma of the BO the board/new board was as normal to overclock as any board and this is how this gigabyte feels atm.
if anyone has any tips or a list of voltages/timings/settings to try im all ears before I rma this board
thanks
Reset BIOS defaults, then just set fsb to 400 and drop your multi.
If that doesnt work i'd think its RMA time.
My old E8600 took 1.55v (real) to clock upto 5Ghz on air, I don't think I ever got it to boot into windows at that speed at any volts on air.Quote:

And even then, they will never be anything but benching stable.
Actually I tried up to 1.88v with VTT at 1.76, MCh 1.80, PLL 1.80, DRAM 2.0, I tried several different straps with every different memory speed. I haven't been able to get into Windows at anything above 4.7 no matter the voltage.Quote:

Well, consider the fact that both of my E8600 on water in Rampage Extreme will not run 3D at 4800 at 1.625V.
guys has anyone done the droop mod that hicookie posted here
does it work properly?
Will let you know next week buddy ;)

Benny, if you have any BIOS settings for high FSB and 333 strap could you please share?
540 MHz max boot with strap 333MHz . 550MHz up with SetFsb = Freeze . With LP on 10. Higher it's the same thing.
quick everest training with QX :p

Similar with VTT but a bit bigger window.
Sorry but ,my two OS are dead :( . I have no more time for repair one.
VTT on auto ,i keep that.
LP 9 was fixed in the bios. LP 8 no tested .
My last result on everest
That's not a high FSB.
PL9
very nice
i saw some old settings of yours in the thread but they don't do anything for me
just trying to boot past 590MHz FSB and have no luck
setfsb doesn't give me much more than 600 at 580/590 boot
with DDR2 board i was benching 620*10 the other day 3D
I have no prob posting at up to 615mhz fsb into windows with any of the first 3 ddr strap settings on the drop down list prob is only the 5:6 is stable so 600mhz fsb=700mhz ram and really any fsb over 560mhz with 5:6 is only one that can finish 2x 32m's at once :(
I can get at 500mhz fsb all the dividers to work that give 600/800 and 1000mhz ram speeds but the stabilty even with high vchp and ice water on the chipset with ek blocks doesnt help at all
After seeing some guys like 3oh6 getting good dual 32m speeds I think it has to be that some boards are better than others by alot :(
Ive measured vdimm in the ddr3 slot and I know what the ram can do via every ddr3 board to date Ive ran this cellshock on and this board just cant seem to run high ram speeds or run the ram stable at all.
and forget all that everest stuff as I can do that at 600mhz fsb with 1000mhz ram speed but single 8m errors out in loop #2, lol so that benchmark besides for showing off for a 2second benchmark does nothing to show overall stabilty on this board :(
LP8 it's possible ,next time i will test that .
LP7 with 1000MHz 8-8-8-24 it's possible too . Around 12500 on memory read.
NB air , cpu cascadeQuote:

I just have been playing with max bandwidth.
@BulldogPO : nice m8 ;)
alright, this is the EP45T locker room so i will ask here.
anyone else find this a bit strange?
sorry for the big screenshots but i am too lazy to make thumbs...
500x8 4000MHz 1:2 1000Mhz 7-6-5
http://img.photobucket.com/albums/v2...00_2-16v-1.png
500x8 4000MHz 1:2 1000Mhz 8-7-6
http://img.photobucket.com/albums/v2...00_1-86v-1.png
note how the bandwidth is identical and the only change, and i mean only change, are the memory timings
and voltage. CL7 wouldn't run with any less voltage and 32M errors out right away at CL7 whereas CL8
ran 32M fine at those settings. so obviously it is CL7...but shouldn't bandwidth be a pinch higher? i don't
honestly think i have ever done a direct comparison between 8-7-6 and 7-6-5 bandwidth before so i could
be out to lunch. i wish i could have ran 32M with both setups to compare results :(
yeah that's odd
both times are fast but it seems that CAS7=8
only thing now is 32M that will tell them apart
exactly, bandwidth can only tell so much. i couldn't even get 5 loops out of CL7 though to get an idea.Quote:

530FSB tRD7 to boot or not blue screen immediately if lowering in Windows...i love to hate this board but
there is a lot of potential somewhere in here, i just can't put it away ;)
Ill be putting mine away promptly after GOOC believe me.
Never had such a buggy chipset before.
Unfortunately unlike all you guys, it seems that my Patriot 1866 sticks wont run at 1000 at all. Maxes around 940 somewhere regardless of timings and volts.
What stick are all you guys using who get crazy high clocks?
haha, priceless, i have put it away a half dozen times but then a new BIOS comes out or someone startsQuote:

look at that bandwidth
how the hell did you pull off Trd7 is beyond me
is that NB watercooled :D....1.7v nice
All these posts about bandwidth, and yet we still cant get any decent CPU/Mem clocks together at the same time making the board basically useless for extremers.
Yesterday wore my patience down to almost nothing with this board.
Sitting there for HOURS trying to get 500fsb on QX stable was futile.
not all that uselessQuote:
