what PL should i use at 400fsb with 4gb of ddr2 1066???? so far im at PL8

[Touche]

The only two parts that are the same in all this are the power supply and the Cpu I don’t think it’s the power supply because no matter how many HDD or fans I plug in when the system is standard it runs fine its only when I OC.

Post your BIOS profile. And HDDs and fans don't draw a lot of power, so it still could be the PSU.

sorry for this belated reply T,.. i was so damn desperate to make my system stable above 450fsb, it wont boot, try up to 1.46nb and 1.3vtt for 4.050 9x450.. then i read some post here that u have to adjust mchref and clockskew to get higher fsb.. set mchref from 0.65, 0.68, 0.70, 0.72, found that 0.72 is the best spot above 500fsb, tried also from 1000mv to 700mv for clockdrive i found 700mv also the best setting, don't have any idea why..

Thx for the answer. So it's FSB related. I was hoping it was something that could get my e7300 8x500 stable without requiring too much vcore. It's 7.5x500 stable now.

Arapab79: ...snip... Don't use Crucial ram, and be aware of bootstrap bug as described in this thread which renders some bootstrap settings useless. ...snip... I would recommend taking it back for a refund. snip

Absolutely no problems with Crucial RAM here. Don't rely on auto settings.

asap:
How come you changed these?
Advanced Clock Control
CPU Clock Drive...........................: 700mv
PCI Express Clock Drive................: 700mv

What difference do they make?

I was running off a template I found on here, and they were changed!

, i'm still stressing right this moment, similar setting like your 7.5 multi, just wanted to know how low can i go with vNB and vDimm with 8GB without going less than 500fsb, VTT at stock, MCHref still 0.72



thx
asap

EDIT:
i just RMAed these set http://www.newegg.com/Product/Produc...82E16820231184, i bought 2 sets hoping will perform better than my team dark, i was wrong, couldnt get stable at 1066 CL5 2.1v, even at 1000 i need 2.2v to pass blend ,... do i need more MCHcore or vDimm to get PL9? my team dark currently at PL10, when i set to PL9 it wont boot...

[Phunky Phish]

Tried 460fsb settings as post #1906 but failed prime immediately!

@ Touche
Will try ths now!
Disable LLC, set vcore 1.41250, leave ICH core 1.100v. Set memory PL 11 or higher.

@arapab

This board is in mine opinion picky with MCH core volt and MCH ref but once you have learn how it works it´s okey, sometimes a lot of trail and error is required.


Use this templet for your bios setup, that way it´s easier for people to help you.

Right, I think thats it for today.
May try and squeeze it up to 4.1Ghz tomorrow

I have saved this as a profile and then enabled CPU EIST & CPU (C1E) for everyday use.

That ok you think?

[radaja]

gar,i think at 400 fsb you might be able to run pl7,just give it a shot.who knows maybe even pl6?these A3 revisions can run one notch lower than A2's.

[redrumy3]

so here's 100 passes of linx with 3.6 @ 1.4v and memory 400 x 9 4:5 2.1 turbo setting in bios

linx makes cpu much hotter than prime but i leave my room windows always open so its nice and cool in my room

[OC Nub]

This is my first Gigabyte board. The bios was intimidating. Had to have someone to explain the different names for voltages then what i was use to seeing on the Asus boards. Thanks Rattle!
Was able to get over the 460 FSB wall with little effort. Did a short prime run this morning, will test longer tonight.
Very good board so far.

[BuGjAE]

Just manage to the first Hitz on Crucial Kit 2.40B strap.... 550x8 PL 10- 11I'm give up right now Just see the same score on memory benchmark compare with 533x8 PL 9 it's the same. and can manage to get stable easier

P.s.Notice that Mch core over 1.22 can't boot up with 2.40B strap

Lower your vcore man. I can run 471x8.5 stable at 1.300bios

[clo007]

So through all my heart-ache with this damn board...actually two of these boards. Well I get the idea to try slots 1 and 2( single channel I know) and it freaking booted. I am thinking sweeeeeeeeeeeet. So I restart with the sticks in slot 1 and 3 for dual channel. no freaking boot!!!!!!!!!!!!

[Ghostleader]

so here's 100 passes of linx with 3.6 @ 1.4v and memory 400 x 9 4:5 2.1 turbo setting in bios

linx makes cpu much hotter than prime but i leave my room windows always open so its nice and cool in my room

Nice OC, time to go for FSB 450 with that Q6600.

LinX is a real CPU killer, you should try to use max problem size and max memory use, that way you put much more stress on your memory and MCH (NB) together with your CPU.

With the setup in the screenie below my CPU has a temp at ~65C and the MCH at ~42C (with a temp probe stuck inside MCH heatsink)


Here´s a screenie with Q9650 / 500 / 4,0 / 2x1 HyperX PC9600@1000 / 555 15 / tRD10.

Stable with 50 loop LinX (max problem size and max memory use), Prime95 blend 2hrs and 30 loop (~2hrs) Crysis Assault Harbor@high.

If I go one step up or down with MCH ref LinX error with in 3min, kind of sensitive or what.



Now it´s time to leave XP (32bit) and go to Windows 7 (64bit) for some 2x2 and 4x2 ram test.

mm i just noticed the memory was only 772 grr im going to run it again now with is using as much ram as it can and see if it passes and then next step is
450 x 9

Good luck with that one.

[redrumy3]

Good luck with that one.

yeah, going to run linx tonight since i just ran it for an 1 hour and 15 minutes and only 12 test completed so, to long for me to wait (have to play L4D :P) so i will let it run overnight, im just worried 450 x 9 is going to take at least 1.55v or more =/ i really need a Q9650 or Q9550 =[

[Leeghoofd]

New bios for the EP45T UD3P : F5 and boy is this finally a good step in the right direction !! most divider issues are gone and I can run the same specs at lower volts than before ( FSB term and Nb voltage)

Running at the moment 500FSB with 1600mhz rams 8-8-8-24 PL 9 with just 1.32NB voltage hyperpi 32mb stable

Grab here : EP45T UD3P F5 bios

E7400 is a nice CPU too

, i'm still stressing right this moment, similar setting like your 7.5 multi, just wanted to know how low can i go with vNB and vDimm with 8GB without going less than 500fsb, VTT at stock, MCHref still 0.72

Ah, nice chip you got there

do i need more MCHcore or vDimm to get PL9? my team dark currently at PL10, when i set to PL9 it wont boot...

Either or both

Right, I think thats it for today.
May try and squeeze it up to 4.1Ghz tomorrow

I have saved this as a profile and then enabled CPU EIST & CPU (C1E) for everyday use.

That ok you think?

Nice, glad you got there
If it's stable, leave EIST and Cx enabled. And thermal monitor.

what PL should i use at 400fsb with 4gb of ddr2 1066???? so far im at PL8

The lowest you can get stable

I'm just curious if anybody hates the UD3P as much as I do.

Here are some of the problems. I start in windows, set my EasyTune 6 settings and run my Q6600 at 3.8ghz on prime for 4 hours no issues. I then re-start my pc, set those exact same settings in the bios and the pc does not start at all. It just cycles on and off for a few minutes (nothing i can do about that) until finally it works and takes me to the bios. In the bios, my voltages are COMPLETELY off.

example: my MCH Refference should be 0.76V and sometimes in the bios it is .86, sometimes it is .6V - and this is completely random. this is not the only setting this happens to. My MCH/Dram reference voltage is sometimes WAY below stock which is why sometime my pc doesn't boot at all.

After struggling for half an hour at a time to start my pc, I decide to set everything on auto. Upon entering windows ET6 reads my CPU PLL at 1.85V ....

I have to say I am very mad because of this. Sorry for this highly negative post, but I do not understand why my settings do not stay put in the bios, and sometimes the voltages that go through my pc are quite dangerous..... I'm using the latest bios, F7 I beleive. Does anybody have any idea what may be going on here? I have never had this much trouble with any motherboard before.....

edit. Another example. My cpu termination should be 1.38 volts. My pc started with it at 1.5volts....
my final problem is that no matter what, I cannot run my ram at stock speeds. I should be able to do 1066 at 5-5-5-15 timings. I cannot go over 844 at 5-7-7-20....

That said, when I DO get it running properly, it runs stable as can be.

I wanted to run @ 4.4Ghz. but Prime kept failing a couple min. into the 800000 with FFT length of 8k. So running small FFT's I tried about everything without raising Vcore. Everything failed just after 3min. It would run 13min though after changing the Vref to .800v from .760v. A huge improvement actually. There is a relationship between Vtt and Vref so you can go too high on Vref if changed alone. In the end I needed to raise Vcore after all. All else is the same since last post but:
Vcore........................1.3375v ****************** MCH...............1.20v
CPU Term..................1.20v ****************** MCH ref.......... .720v
CPU PLL...................1.5v ****************** MCH/Dram ref. .820v
Vref......................... .800v ****************** VDimm.......... 2.18v

Used Crucial 8500"s. 4 hrs of small FFT's.
