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

[Mysterfix]

Those measuring points are not accurate, Gigabyte has yet to confirm where they really are. I tried to ask on their official forum but only got points for another board that hardly compare to this one.

Thanks for the reply bro and that's good to know. I thought for sure my board must be borked.

[Touche]

Hi folks,

I need help with OCing my e7300, i can't seem to push it past 3.4ghz and make it stable enough. Any thoughts would be appreciated.

e7300 @ 3.4ghz 400x8.5@ 1.3v

More vcore.

So what do you think Jor? In your opinion is it still safe to use 1.50/1.57PLL on this board with 45nm's? BTW, I fixed my rig, stable at 476x9 now 1.39vcore! Thanks to you and Hoss for helping me! When I run my final blend test I will post all settings and information.

Are these the voltage read out points you were looking at? http://www.hardwarecanucks.com/forum...review-15.html

[Hardc0r3]

does anyone here have a 5.1 analog system conected to this board and using vista x64 sp1 cause i can't use the realtek drivers to work well with my speakers. Even tried latest version 2.18 still no rear speakers detected under 5.1 configuration The windows drivers work well no problem, but i think it should be more.

That's great news Slim, I'm glad I could help a little. You should e fine with those PLL's. I didn't need more then 1.5 all the way to 4750Mhz.

Nice find coop.

According to the review "the EP45-UD3P has terrific voltage output. There is very little variance between what you select in the BIOS and what the board actually outputs. The DIMM, NB, PLL, and VTT voltages are very accurate and stable, showing no variances between idle and load states."

So the value you set on BIOS for NB, VTT and PLL it's pretty much the real one, if you measure those and the output is way off I would be concerned and double check DMM batteries too.

But then again, every motherboard/psu combo should output slightly different values and that can change even from cpu to cpu type.

i have the same problem, never got it to work with analog, 5.1 at less, i only get real 5.1 with digital S/PDIF

[coop]

I agree Jor3lBR, the accuracy is about spot on. Great product.

[Mysterfix]

Are these the voltage read out points you were looking at? http://www.hardwarecanucks.com/forum...review-15.html

That is the point that I used to measure PLL voltage and mine reads exessively high with anything above 1.45v. If I set it to 1.5v in bios I get 1.63v-1.66v under load. I've been doing some experimenting and this does seem to be the correct spot. When I change PLL settings in bios the voltage from this spot changes and none of the other voltages move.

So what am I to do, keep the board knowing that it has issues with voltage regulation or return it for a new one?

Edit: I think I'm going to return this board tomorrow and hope the new one has proper regulation, this one is F.U.B.A.R. and I don't want to take the chance of it giving me some magic smoke and taking my quad away with it.

[xavisimao]

can somebody post recommended bios setting for stock (2.4ghz), 2.8 ghz and 3.0ghz?

Here is my stock BIOS setting, I always get a BSOD or lag during games.

xavisimao, start by setting your vcore manualy and see if that helps. I would also set vtt and pll voltage to defaults instead of auto.

[Dem]

does this m/b needs more MCH voltage than other P45s ?

as stated here

http://www.clunk.org.uk/forums/revie...html#post48572

I am to choose between EP45-UD3R and P5Q - E( or deluxe@more expensive though)

or is only that MCH Reference thing you are talking about all the time...sry , 975X here no idea about P45, yeah a little bit old fashioned

[oMek]

I've had this board for about a month now, my cpu overclock is stable 4000hmz@8x500 but im really lost on the memory settings.

here is how its set now.. (dont pay attention too the volts I was messing around trying something out :P)

Im looking too either get my ram too 1200mhz, or keep it at 1000mhz with better timein, whatever will give me better memory bandwith

i have the G.Skill PI8800 (1100mhz 5-5-5-15 1.8-1.9v)

anyone help me with my memory settings/overclock?

[radaja]

im pretty sure those sticks will not do 1200.but one thing you can change is ,set trfc to 55.i used to run mine at 520x8 and at 1:1 that gives your memory 1040.you can also try 471x8.5 and run the 333strap 2.40B should be around ddr1130 set pl8

DUDE! 1.71PLL is not a good idea! Your going to be way way way better off with 8.5x471 running the 2.4B strap and much much less VTT/MCH. Try these and see if you can boot. If not raise your VTT/MCh to 1.32/1.32, raise the VTT first and let the references adjust. You should be running something like ~65% of the VTT for a reference and ~67% of the MCH for a reference. You can run 2.0V ram at first and then lower it later. Get rid of that 700mv/700mv and 200ps clock skews. Try 900/900/0/0 or 1000/1000/0/50. You can also try up to 1.57PLL but NO MORE. Boot with these setting first though. Good luck

well i tryed your settings, so far so good! i feel much more safe with the lower volts. i lost some memory bandwith via everest but that could be due too my raid volume rebuilding atm.

going too stress it some and see if its stable now =) thanks!

Great! Just remember that using the 2.4B strap might prevent you from running 1.34VTT/1.34MCH(I do not think you will need it that high) so don't freak out if you can not boot or instant BSOD if you try that high. I think you might be able to go lower on the ram then I suggested but make 100% sure your vcore/vtt/mch levels are stable before lowering your ram. If you get BSOD's or prime fails do not change to many settings at one time. Those settings are pretty much identical to what I can run my 9650 at with 9x471, since you have a 9550 then 8.5x471 should be spot on.

[TheGanG]

im pretty sure those sticks will not do 1200.but one thing you can change is ,set trfc to 55.i used to run mine at 520x8 and at 1:1 that gives your memory 1040.you can also try 471x8.5 and run the 333strap 2.40B should be around ddr1130 set pl8

GA EP45T UD3P / DDR3 is pretty good about timings. But i would love to play with a GA EP45 UD3P / DDR2 too.

Anyone diced Q9650 / GA EP45 (EP45T) UD3 series here?

[DOM.]

okay i got 4GHz stable @8X500

what needs to get more volts besides v-core to get more Mhz stable ?

+VMCH and plus all kinda reference voltages' must be in a good balance.

[mattlyall06]

for the life of me i just cannot get this stable. i get either a bluescreen or a failure of prime/occt about 5-10min in. im using Jor3lBR's template for 4.41ghz

the only things i changed are i set the ram to 1:1 (333mhz strap 2.0 multi) and DRAM voltage to 2.1. the driving strength profiles, channel a & b, should i set those to 1066? i've even gone a notch or two higher Vcore, giving me 1.392 windows and still no go. grrr.... its odd because, i boot into windows in under 30sec, just like i do now @ stable sig settings, everything seems smooth and groovy. i dont know how to tell if i need more vcore or if its the mch/cpu ref values that need tweaking.

any ideas?

Not all that CPUs are same, yours may need more VCore and VMCH. And what about cooling? Cooling is an issue with that CPU...

[Leeghoofd]

does this m/b needs more MCH voltage than other P45s ?

as stated here

http://www.clunk.org.uk/forums/revie...html#post48572

I am to choose between EP45-UD3R and P5Q - E( or deluxe@more expensive though)

or is only that MCH Reference thing you are talking about all the time...sry , 975X here no idea about P45, yeah a little bit old fashioned

Not really, if you get a good balance between the reference voltages you can run almost as low as the Asus series : eg for 580FSB/DDR3 action I need 1.36NB, on the Asus I needed 1.33 set in bios ( 1.34 in reality) Many users push high FSB and NB volts here due to the fact that the reference voltages aren't balanced. I alos got a DDR2 version now and it's way easier to setup than the DDR3 one I got. These boards are fab, but needs some tinkering to get it soaring ( and there seems to be some variation in the biosses between the different versions )

good evening lads
got my hands on an e8600 today,currently got it at 4 gig 10 x 400 @1.28vcore idling at 34/48 under load.i have tested it under orthos for an hour and its stable,
i use cpu-z and it always shows that my multiplier is x6 but this is not true, should show x10 - also the program will not show what mhz the ram is running at,shows timings only,
i downloaded the last cpu-z 1.50 and the same with that.even realtemp show x6 and occt also shows x6 , am i missing something here.like a performance saving setting,lol,
any advice would be much appreciated or tips on futher overclocks as i think this has a lot more to give.24/7 i am after.
i also bought the new akasa nero 1366 cpu cooler,it is massive and quite fiddly to get all the springs to lock,and getting the fan attached with the rubber bits is scary,you have to pull so hard you think the rubber is going to snap.
its running max 1680 rpm and its whisper quiet so i am pleased despite the hard work getting it on,dont want to mess around with that again if i can help it,next thing will be to source some ram which we let me go further.want to get at least 1250mhz but dont think the ram is up to it.
any suggestion or advice on any of the things i have talked about will be great to know,take it easy lads.
