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

[Ghostleader]

OK, So I got my new UD3R, thinking my other one was screwed up. If you can remember, for some reason my motherboard will not run 2 sticks of ram no matter what size. So I bought a new mobo since newegg would not replace and gigabyte still has not sent me any kind of RMA confirmation for the mobo. Anywho, fast forward to today. I got the motherboard, rev 1.1(interesting the NB/Sb coolers are a bit different in finish and sizes then from rev 1.0) so i reinstalled with new motherboard. Well, this one won't run with 2 modules either. Also, once I installed it, it would hang as soon as my desktop came up. So i grabbed a spare HDD and installed Windows fresh. No more hang but I still can only run one module. If I put 2 modules in it won't even get to bios.
Does anyone have any clue what this may be from? I am thinking maybe a PSu issue, as my HX520 is almost 2 yrs old now, but for the past 3 weeks, I have been running at 471x8.5 with no issues, except the ram issue. I am so puzzled right now. I have 5 different sets of ram that I have tested with all the same effect...1 stick=mobo runs, 2 sticks= mobo won't post even to bios.

First: Sorry for my bad English.

I have the same Problem like Jor3lBR with 2x2048MB RAM, DDR1066 and MCH-Voltage, he discibes on Page 58/59.

but it is more bad, my "Stuck" MCH -Core is 1,2V!!

Corsair Dominator 2x2048MB DDR 1066 5/5/5/15, the CPU is a Q9550 E0.

When i set everything to DEFAULT (FSB333x8,5, DDR1066) i can boot and everything is fine. Even DDR 1080 is no Problem.

But when i raise the MCH-Core Voltage over 1,2V the Board loop in Reboots. I must turn down FSB to 325 (DDR 1040), then i can boot.

I need higher MCH-Core Voltage then 1,2V for my Quad at higher FSB, but then i cant run DDR 1066or higher!
(For Example FSB 445 and 2.4B=1066 -> not possible over 1,2V MCH
FSB 433 and 2.4B=1040 -> possible with 1,2-1,4V)


What is the Problem, is the Board damaged or the RAM incompatible?

Any solution?

I have similary problem, at first I had some problem to get my E8400 and 2x1 Kingston HyperX PC9600 to boot at FSB 450 ram 1200 555 15 tRD7 (Strap 200, Multi 2,66C) and FSB 500 ram 1200 555 15 tRD8 (Strap 333, Multi 2,40B) but with a lot of tweaking and help from people in this thrread I made it but about 2 weeks later it just refuse to boot at those setups, no matter what I did.

Then I tried to run my 2x2 Corsair Dominator PC8500 ( they are on the compatible list) with FSB 333, 400, 450 and ram 1066 and 1080 but it refuse to boot with it, I tried the same with one stick it was okey but not with two.

I can run 433 1042 but with 434 1044 there´s no boot.

If I run 1:1 there is no problem at all, I can reach all the way up to FSB 575 ram 1150 555 15 tRD9 stable without any problem.

There seems to be something strange going on with some of the straps and multi on this board, I also want know what´s going on, I hope somebody can help.

[Max25]

I can run 433 1042 but with 434 1044 there´s no boot.

Could it be? The same Memory, the same Problem.
I have exactly the same problem. I can run DDR 1042, but over 1042 i got Bootloops/NoBoot. But only when i raise the MCH-Voltage over 1,20.
How have you set MCH-Voltage? Try to turn under 1,2V and test.

This is the exact same problem I'm having - I have a UD3P. I've tried 2 sticks of G.Skill Pi Black 6400 and Corsair DHX sticks. In combination, in alternate colored slots [to try and force single channel mode], etc etc. Will not run 2 sticks no matter what.

Are you getting a continuous series of short beeps when you put two sticks in?

I have a Seasonic S12 600W, and it's a really solid PSU that is not being even slightly stressed, so I can't believe it's the PSU...

[radaja]

almost there .500fsb here i come.

[Max25]

almost there .500fsb here i come.

When their are Problems they will come with the FFT768 and FFT640....

This board is really strange for me. Trying the 8.5 multi now, test at 533x8.5 and memtest is stable, tried different settings(lower PL) and got it to fail memtest, then changed back. Anyway it boots just fine but will not run anything(well any stressful stuff, like super pi crashes instantly when running most of the time), even if I change the FSB down to 490, or 500/510, ect...

I have been trying everything I can think of and there must be a magic setting somewhere. Went lower and higher MCH and mch reff, same for VTT. Tried adjusting the skew settings. Its very strange.

I did notice that when running lower volts and speed, that the 2.40B strap seem to work better than others as it lets me run 3.87Ghz on stock 1.25 volts. But my mem is only 2x2GB 1066 OCZ and wont go very high.

So far the highest I can go is just lower than 4.4Ghz, on either the 8,8.5 or 9 multi and using 1.40v in bios, going up to 1.45v doesnt help

[Max25]

Something more with problem:


FSB 333 - 3.2B DDR 1066 - MCH 1,2V -> RUN
FSB 338 - 3.2B DDR 1080 - MCH 1,2V ->RUN
FSB 333 - 3.2B DDR 1066 - MCH 1,22V and higher- Bootloop
FSB 325 - 3.2B DDR 1042 - MCH 1,3V -> RUN
FSB 326 - 3.2B DDR 1044 - MCH 1,3V -> Bootloop

The same with 2.4B:

FSB 445 - 2.4B DDR 1066- MCH 1,3 -> Bootloop
FSB 433 - 2.4B DDR 1042 - MCH 1,3V -> RUN
FSB 434 - 2.4B DDR 1044 - MCH 1,3V -> Bootloop

Just thought I'd share my initial experience with this board. Got things fired up a couple days ago with my trusty E6700 (waiting on a new proc), so the system is as follows:

Operating System- Windows XP
Motherboard- GIGABYTE GA-EP45-UD3P LGA 775 Intel P45 ATX Intel
Processor- Intel Core 2 Duo Conroe E6700 @2.67GHZ
RAM- G.SKILL 4GB (2 x 2GB) DDR2 1066 (PC2 8500)
Video Card- XFX GTX 285 1GB 512-bit GDDR3 PCI Express 2.0 x16
Hard Drive- 1TB Western Digital Caviar Black +74GB raptor + 500G Samsung
Supply- Antec TruePower Quattro 850W
CPU Fan- Tuniq Tower
Case- Antec Twelve Hundred Black Steel

Installed windows and everthing went great, but in cpu z it was reading 2.1Ghz. Kinda strange, so I checked the bios and it had set my multiplier to 8 for some reason. Didn't really think anything of it and set it back to the stock 10.

Then decided to do some quick OCing. For some reason the thing would not post if I upped the FSB anywhere over 266 with a x10 multiplier and changed the RAM speed multiplier to run at 533. Not even 3ghz. Kinda strange, so I changed the cpu multiplier to 8 and it booted anywhere I'd set it after that, 3.0, 3.2, 3.4,3.6, and 3.8ghz regardless of me changing the RAM multiplier to keep it at 533mhz. I only messed with multipliers, vcore, and FSB. I don't know enough about the other voltages to start messing with them.

For some reason the board hated a x10 multiplier but is happy with x8. Just FYI I guess

First start or after every flashing (bios is in Fail-Safe Defaults-lower multi and higher VDimm) in BIOS choose "Load Optimized Defaults", save and apply.

[radaja]

so close. i two more notches on the fsb and im there.mind you im running mem at 1:1 divider.not what i wanted for my goal.tried 5:6 and i could only get to 468fsb so i switched dividers and started having better luck at achieving my goal of 8x500 @4.0ghz with mem@ddr1200 pl8.so i guess im almost half way there.i know the volts are kinda high,but that what it needed to get stable.anyone with a 9650 and experience with the UD3P,i sure could use some help and advice with lowering some of these voltage values.thanks

Those temps are insanely low Is that on your TRUE, and is the chip lapped?

[radaja]

ghost,yes that is on the true.chip is not lapped but the true is.im using my airconditioner with a dryer vent hose to blow cold air directly into the intake.if i was to turn it off temp would be steadily at about 50c to 55c.when i was running this ss my motherboard sensor got as low as 6c.

[Max25]

Until the high MCH-Core there are not to high Voltages. Are you sure, you need 1,46V?

I can run my Q9550 stable with 8,5x500 with 1,4V MCH, the other Settings are not far from yours. My Q9550 likes higher GTL Voltages then yours, you have 62%, i need 65% (DEFAULT 63%).

Those temps are insanely low Is that on your TRUE, and is the chip lapped?

Try the Sensor test and post here. What Cooling?

[radaja]

max25 yes it seems to need 1.46mch,i think it cause im running four sticks of ram maybe.not sure though.i couldnt get it to run more than 2minutes in prime95 when it was at 1.42.but thanks for the info on the gtl values maybe if i adjust these i can lower some of my other voltages.also not sure what your asking about with sensor test.i assume your refering to realtemp?my sensors work fine except one is stuck at 36c another is stuck at 31c.but once i put the cpu under load they all scale good.ghost recon was asking about my temps being low and i explained why.GHOST heres two ss of my computer at idle with airconditioner on and then off.ok.

[jess1313]

Whats the max vcore supposed to be on these boards? I just got mine (ep45-ud3p) up and running, and it seems max is 1.4v in bios and in ET6. I have seen screenshots of up to at least 1.45, maybe even 1.5v I don't want to run that high of voltage 24/7, but I would like to bench using that much every now and then.

I am running an odd cpu for now, until my e8400 comes in. That may be why, its a prescott 520. The board may automatically limit the vcore to different levels on different cpus.

Any ideas?

ps: f7 bios

[turbotrey]

Any ideas why my Linksys wireless card would stop working when I turn my FSB up a little? It worked fine on my Abit at 445x9

[SimpleTECH]

Most likely at that FSB setting it is unstable. Some applications of mine begin to get fickle so I know that my overclock wasn't stable to begin with.

What is the rest of your settings?

[radaja]

500fsb with my new 9650.im half the way there.now i just need to get this setting to boot up with ram runnung 5:6 ddr 1200.

[bluestang]

Thinking of replacing the 120mm x 120mm x 25mm fan on my ZeroTherm Zen FZ120 with same size fan but with more CFM. Current spec is 1800 RPM, 60CFM and 31 dBA. Looking at Scythe S-Flex SFF21G Fluid Dynamic Bearing that is 1900 RPM, 75 CFM and 34 dBA. Will that extra CFM make a huge difference in load temps that are maxing at 54C/52C?


By bluestang

[radaja]

blustang nice OC,and yes it will improve a little.can you use two in push-pull with you cooler? thats what i do and it helps, brings it down 3-4c.

[clo007]

I have a Seasonic S12 600W, and it's a really solid PSU that is not being even slightly stressed, so I can't believe it's the PSU...

I get no beep codes at all. My computer just power cycles over and over. It won't even get to bios screen.

[clo007]

Something more with problem:


FSB 333 - 3.2B DDR 1066 - MCH 1,2V -> RUN
FSB 338 - 3.2B DDR 1080 - MCH 1,2V ->RUN
FSB 333 - 3.2B DDR 1066 - MCH 1,22V and higher- Bootloop
FSB 325 - 3.2B DDR 1042 - MCH 1,3V -> RUN
FSB 326 - 3.2B DDR 1044 - MCH 1,3V -> Bootloop

The same with 2.4B:

FSB 445 - 2.4B DDR 1066- MCH 1,3 -> Bootloop
FSB 433 - 2.4B DDR 1042 - MCH 1,3V -> RUN
FSB 434 - 2.4B DDR 1044 - MCH 1,3V -> Bootloop

All of those fail for me. No matter what settings, if I have 2 sticks of ram in the mobo, it bootloops. If I have 1 stick, it fires right up.

This is pissing me off. I have a rev1 and a rev 1.1 it does the same thing on both of them. Rev 1 was on f5 bios. rev 1.1 is now on f6 bios.

[turbotrey]

Settings right now, Linksys is working. I'll post one up in a sec of it not working.

That's a mystery I'm starting to believe this board doesn't like G.Skill's and Crucial so much especially low rated ones (below PC2_8500).
