** Official ** Gigabyte UD3 P45 Series -- EP45-UD3 / EP45-UD3R / EP45-UD3P

you're right, sorry, i didn't read every words you wrote above.
it's new to me about the volt limitation problem on the NB, this due to i've never needed more than 1.40v, i'll try a more higher overclock on my quad and try using more NB volts and see for myself.

and btw, if i recall correctly, when i used XMP profile, i also set Turbo, and i didn't set tRD value in the bios.
for an example, on my 8800 PI kit's EPP timing (or XMP profile 1 in bios) it would be like 5-5-5-15 / 4-4-13-68-4 (this's a stock timing for DDR2-1066 as an EPP), and i used to use the timing to overclock the ram kit and it worked quite okay.
so all i did was to set the XMP at profile 1, set Turbo, and didn't set the rest of memory timing and tRD value at bios to auto.
Everest's memory read/write/copy was a little lower but not that lower, and i think Everest's L2 Cache read/write/copy was improved.

@Jor3lBR,

i like to update about the NB/MCH core voltage limitation, i just tested it right before i posted this.

this is a 1.50v MCH core, i set MCH ref. to "Normal"
after the CMOS is saved the system boots up fine in to Windows, i already try rebooting a couple time to see if it boots, it's seem okay so far to use MCH core voltage above the value you mentiond with 333 strap and 2.4B.

http://img172.imageshack.us/img172/7...7130557ob7.png

the rest of voltage and ref. settings in bios i just happen to picked all these values when i set the CMOS just to see if i could boot the system. this doesn't mean i can stable my Q9300 with this setting yet.
however, it seems to me that may be i will need less voltages than this since my 500x7 stable with quite less volts than this one.

Hello

I need some advice from u. I got some new RAM OCZ Reaper Rev. 3 1066 version. I want to run my RAM in PL9 but it doesn't boot with it. I tested 333 and 400 strap. I got 510 RAM clock run with 2,4b and PL9. But no Boot with 510 FSB 2,0B and PL9.
Here is a screen for higher FSB

Thanks for looking into this panging :up: I tried everything but it's a still no go, probably I need 1Gb sticks it may be ram related.

Using 333/2:40b strap if I boot with NORMAL on MCH volts it will get in Windows with 1.1vmch :ROTF: and if I try to raise to 1.5vmch on ET6 = Instant OS Freeze. Again if I raise in increments to 1.440vmch everything will go fine but after that freeze in OS or no boot in DOS :shakes:

If I boot on AUTO (Mch core) it will double boot and restore defaults, probably because it's trying to set it above 1.440mch.

Funny thing is nobody on Gigabyte seams to have an answer for this.

Oh before I forget I have 2 boards and tried this on like 4 boards. Versions 1.0rev and 1.1rev.

I will try 1Gb sticks and see.

Hello there your full bios template would easy our job here, just copy from last page my template and post it here between the CODE tags (click on the # on the toolbar and put the template in between the CODE tags).

2:40B strap requires a little more volts then normal and also PL9 will require more MCH volt and more Vdimm volts too.

Remember the voltage you set for Vdimm in bios is a little higher then reality. 2.3vdimm in BIOS = 2.26vdimm in reality from my measurments. So if your setting 2.15 will be more likely that your ram is receiving less then 2.1v.

You can also try settings the RAM References and Terminations one step lower then the default 50% it's set, so for 2.0vdimm Ram references and terminations shold be 1.0v I would lower that to the next step down.

Again send template so we can help you better. Template example:
Hit CODE (#) on toolbar and add the template:

Thanks Supershanks for the settings. I'll give those a try and see what happens.

:up:

I thought i'd cracked the ram stability when i got it running at 4,320 10x432 @2.66D 1,152 5-5-5-20 but if I try to use 2.00B or 2.00D above 1066 I'm still struggling to get stability. I'm using F6A Bios. Ram is Crucial Ballistix Single Sided 8500 5-5-5-14 2.0v CL1119H.DY.

Had no such issues with the EP45-Extreme , strange .

Anyone mind sharing their settings for 600+ FSB with a dual? I am having one hell of a time getting even SPI 1M stable. It will boot windows all the way up to ~640 but nothing will run above 600. CPU is known to do 650 8m stable on the Tpower I45. Any help is appreciated.

This board allows people to boot and enter windows @ 650FSB on duals, and 560FSB on quads. That is probably because of the Rev.A3 chipset. But due to its 6 power design only, I haven't seen people doing good stable FSB on this board, neither on dual or quad cpu's. Also, this board needs more volts then other good p45 boards, to perform the same overclock, and it heats way more.
For this reasons, I believe so far this is a good board to bench with, but for 24/7, I have my doubts. Maybe it needs better bios or so.

Wow I don't think your been here lately or you own another board... There is no other board that I've tested with my same chip (Q9650) that could do 11hrs Prime95 Blend on Air @ 4400Mhz with 1.37vcore... Because of it's extra cooper the board and components won't heat at all considering the high fsb or mhz's. People that are not stable yet is because they can't seem to find the right combination between MCH ref, Cpu Refs, Dram Ref's etc.

Just read few pages back and you can see these results.

Stability is gained with a lot of work between MCh Ref and Cpu Ref, these value are the hard ones to get at first, don't think that leaving them at the same default value will take you anywhere.

Also playing with Dram terminations and refs are also very important.

I can bust a 8+hrs Prime95 blend stable setup with a slight change in the MCH Ref down or up, thats all it takes...

I'm sorry I can;t help you further because I play with quads :( But I'm sure there are people above 600fsb stable out there.

the trick is too as with most boards you can actually loose your stability with too much voltage people think voltage solves all however you cant jump from 450 to 650 and just up the vtt and nb voltage to ridiculous levels you need to inch up levels at a time then you know whats too much and too little at higher bus speeds things get really finicky

Just for reference

What voltages recommend it for use dry ice in a EP45 UD3P, I have an E8400 so far I have only managed a 530 FSB on air but the temperature is very high.

Vcore
MCH
Mem

can you help me?

@ simps, i dont know why you keep in sisting that these boards are not 1.stable at high fsb 2. require high voltages 3.are not good 24/7 boards 4. heats up more than other p45 boards.based on my own experience all four of these thing are untrue.there was a time in the begining where people were using auto volts(and yes the board set them very high for high fsb).but just look at pangingIII's and others OC's.most require less than 1.38v NB for 545fsb+,and ive seen as low as 1.30 vnb for 545fsb.but on average the volts required for 545fsb+ is about the same as any other p45 chipset board.all three of my maximusII board ran considerably hotter than my ud3p,but mind you my max's are all defective.

Thanks man

I have a GIGABYTE EP45 UD3P

I ran my quad at 503 and it was great, I think that was pretty great for a Q9650, that thing is a monster :shocked: I just love the board, I have owned lots of boards and the UD3P is the most fun board i have EVER owned, it just rocks....

well heres a quick test at 550fsb with 8GB of g.skill pc-8800's.not bad at all.ive only owned three boards p5q-deluxe,maximusII and this awesome board.it really is amazing what can be done on these boards.for instance memory overclocking,many records have been broken since the release of these boards.and the clocks people are getting with the Q9650 is just astonishing.keep it up guys.as soon as the prices drop,i'll be getting one myself and with all the work you guys have done,well it will just make it easier for me.thank you.http://i41.tinypic.com/2h6vl9g.jpg

small backup with old bios F3 Ud3R FSB518x8, 5 @ 4,4 GHz with H2o, my everyday settings are 506x8, 5 @ 4.3 GHz (windows7)
and its pi32m stable

Jor3lBR, radaja, systemviper,

I am sorry, english is not my first language, and sometimes I might not sound the way I want to. I am not trying to say UD3P's are not good. They are, don't get me wrong. I don't think I will be able to explain it the way I want to, so I just won't. Has to do with what I understand (or what I think I know) about 16 phase power os asus boards, or 12 - 8 phase of other boards vs 6 phase power of the UD3P's.

We can investigate, how well this board can do a stable 24/7 overclock, by comparisons. That I think, would lead us into some conclusions.

I only have an aircooled 65nm B3 quad (my board is aircooled too), and most of you guys here are on Q9650. But anyway, I will post how I am running my quad, 24/7 on my Maximus II Formula.
The board voltages required to do it, and board temps, are there on the pic below.
This is 10 IBT loops on max stress and 4h+ prime blend.

Can some of you guys with quads and UD3P, post the same overclock (494FSB) on your boards, and show the same 10 IBT loops on max stress + 4h prime blend, so we can have a comparison, in terms of the volts both boards needs to perform this overclock 100% stable?

I will later, post a 500FSB pic for 24/7 too. But first, let's see how both boards compare on 494FSB, shall we?

I don't wanna make this a competition, please don't understand me wrong. I just want to compare both boards, and see how both performs under 24/7 setting. This might turn out interesting.
The main thing to look on the pics, will be how many volts each board needed to perform the same overclock (vNB, vFSB, vPLL mainly), and of course, if it is stable, by completing those tests. It is important that ram clocks are equal too. In this case, I am running DDR2-1186 5-5-5-18 PL8 STRONGER. There is no setting FSB inside windows, no memset, no changing voltages on-the-fly. Just entering BIOS, setting values, booting, entering windows and running stress programs with bios settings only.

I need less PLL, VTT then I did on my P5E.

fatguy1992,

I see you also have a 65nm quad. That would be ideal to be compared to my 65nm quad, since you have a UD3P. If it is possible for you, try to match that 494FSB and this 500FSB on your quad, and then post pics of it, so we can compare to my Maximus II Formula results, in terms of board volts needed.

As I promissed, here is the pic of 500FSB. I am still priming (1:45h so far), and took the pic while stressing it, so the mobo load temps are shown too. I will keep priming till it reachs 4h. You can see on the pic I ran 20 loops of IBT on max stress this time too. It is just rock solid stable.
I also lowered mem clock to DDR2-1000 5-5-5-18 PL10, so people won't need higher end mem to compare. Almost every memory available today will do that.

The voltages required by Maximus II Formula to perform this 500FSB on my 65nm quad, are there on the pic too, reported by everest.

I am a member since 2002, one of the oldest. And I have 300 posts. Believe, I am not the kind of people that would cheat or lie on xtremesystems. Try to look for guys registered this year, with 10 posts for that kinda trolling.

I am not writing anything on that screen. That is a program called EVEREST. That program has a OSD display (witch is what I use), and you can custumize that display, with different colors, fonts, sizes, etc.
That program "EVEREST" is reporting those voltages and temps. I am not doing anything. And those reports are accurate. There is nothing wrong there.

You can download everest here, and see for yourself that OSD screen:
http://www.lavalys.com/products/down...?ps=UE&lang=en

Also, I have wrote a guide, on how to configure a motherboard (GTL's, skews, etc) to reach high FSB's with low volts. You can read it here, on post #2720.
http://www.xtremesystems.org/forums/...90812&page=109

Here is other SS and a celphone pic I took just now.
I am still priming (2:30h so far), you can name the program you want, I can download it now and show a SS for you, with your program reporting those voltages and temps.

My bad I didn't know there was a program to do that :(

I also use Everest, but I didn't know it had the OSD and thanks for the guide.

BTW I was NOT saying u were lying, and you weren't anyway, I just thought I wrote that stuff.

There is no problem mate. We are fine. Sorry if I was too direct too. My english is bad and doesn't allow me to write the way I want to.

Ur English is fine.

BTW i'v been looking in my Everest and I can't find the OSD?
