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

[OC Nub]

OC nub,make sure ET6 is not set to load any settings.cause that would cause it for sure.

Just uninstalled it, will reinstall and see if that helps. Don't believe i set a profile but may have. Thanks

hi guys im looking at these mobos but im not sure which to get ive heard good things about the GA-EP45-UD3P and for the price but the thing that draws me away is it has only 6-Phase Power vs 16-Phase Power the other im looking at

going to run a E8500 and X3350 see what i get vs my old Asus P5B Deluxe lol

dom7184,you can buy into the myth that more is better and end up spending way too much money on frills and gimmicks or you can simply buy the best 775 board (price/performance)out there.the UD3P performs better than two of those boards in my opinion,and the other two boards i have no experience with so i cant speak to that.but i have seen some very impressive OC's with the DQ6 and the Extreme.but again the UD3P is on par with those two and at a better price.

This is really frustrating.

I bought this board to replace my Asus P5B which was aging fast. I previously had my system running at 3.33ghz with an E5200 and 2 x 2gb of GSkill 1066mhz mem.

I can get the system to boot fine at 333x11 and a variety of other combinations of core and memory speed but as far as getting into windows the system will not get to the desktop with ANY SETTING other than me loading defaults and saving and exiting the bios.

I have tried copying peoples bios settings from this thread but I feel like im missing a major setting somewhere thats preventing my success.

Any ideas?

[radaja]

Snoodge please post all your bios settings so we can help.

[Snoodge]

Thats the problem. I have no bios settings, I cant get into windows with anything other than "Load Defaults".

I have tried copying two or three peoples posted bios settings and those get me into the bios overclocked in some cases, in some other cases the comp just restarts 2 or 3 times or whatever until it realizes the OC failed and then it gives me the message OC failed when I enter setup.

I have not yet updated the bios to the latest version. I just got the board from Newegg the other day. How critical is updating the bios, are there major stability and OC differences between the shipping bios and the latest ones? I have no problem flashing, I just havent gotten around to it yet.

Ive been too depressed about this board not being the second coming of Jesus like Anandtech led me to believe. I hope to change that though with your help and accept it as my savior

Greetings,

I am looking for some advice on my cousin's new build. Here are the specs...

Gigabyte GA-EP45-UD3R (BIOS - F6)
Intel Q6600 @ 3.2GHZ (400 x 8) 1.4500v
OCZ 4GB 1066 Reaper @ 1066 5-5-5-15 (w/ tight alphas) 2.20v
BFG 9800GTX @ 792/1944/2304

We are experiencing a weird problem. The system is Prime stable (all 4 cores & memory). We can run 3DMark and play games all day long. The system can be rebooted over and over, without any issues. However, once the unit is powered down (turned off), it will not boot back up successfully. It will attempt to boot like 3 times (never getting through POST), then it will go back to stock settings and boot. When you go into BIOS, you get the message saying the system didn't boot due to overclocks or voltages... however, you can apply your overclock settings and everything will be fine, until the system is Cold Booted again?! It is very annoying, especially since he turns his system off when he is not using it. Has anyone else experienced this "Cold Boot" issue or have any ideas and/or suggestions? Perhaps it's just a simple fix, like raising a voltage up a bit (I have tried CPU voltage, with no luck)...

-Thanks

NOTE - Only the VCore and VDimm have been raised, all other voltages are still on Auto...

I got that problem when I first got the mobo too, I fixed it by setting the CPU and MCH References to better values. The reference on a Q6600 should be about 63% 67% and the MCH 63% to 67%. To work it out you dived the reference that you set (eg 0.863) by the VTT. So if ur VTT is 1.3v and you have a reference of 0.863 it works out to 0.863 / 1.3 = 0.6638...

That is pretty close to 67%.

Thats how I was told to set them up. You do the same process for the MCH. Some Q6600's and MCH's may like higher or lower references then average.

Sorry if this doesn't makes sense.

If the above doesn't help, try flashing to F5. I've had similar problems with F6.

[Ghostleader]

Here´s my Q9650@500 4,0GHz and 4x2 OCZ Reaper PC8500@1000 555 15 tRD10.

It´s stable with 30 loop LinX (~3hrs, max problem size and max memory use).

Some may do think that my vcore is way to high for 4,0GHz but those of you that use to run LinX with max problem size and max memory use knows that you need it, when I run P95 small FFT I´m stable with ~0,10v less and temp are ~20C lower.

It not only stress the CPU, the NB gets it share to, it come close to 50C when max stress it with original heatsink/heatpipe (TIM replaced), MCH core@1,34v.


I was surprise that I not had to increase any voltage going from 2x2 to 4x2.

Next up is P95 blend, probably I have to run four instances to stress that amount of ram.

i booted at 500fsb 1:1 memory ratio, but i can't get it stable. i didn't know which voltages to increase, so i increased ALL the auto settings currently shown in my template, and it won't even boot. it seems the increase in voltage from those makes it even more unstable, including the vdimm. increased it from 2.0v to 2.1v for the memory and it won't even boot. it's weird how more voltage for the memory actually makes it unstable.

based on the voltage, i'm assuming "MCH/ICH" is the same word for north bridge right? and should i change my memory multiplier from 2.00B to 2.00D? all this does is change the 333 strap to the 400 strap right? i also need help with all the settings i bolded in the template. and is the F6 bios more stable than the F5? i just got this board a day ago, and bios settings are very different than asus boards that i'm use to.

EDIT: i got 500fsb stable by setting MCH core to 1.4v and changing the memory multiplier from 2.00B to 2.00D . but i still need help with the other voltages.

[SimpleTECH]

should i change my memory multiplier from 2.00B to 2.00D?

Do this first.

I cannot for the life of almighty get my Gigabyte board to boot correctly with the 2.00B or 2.40 straps.

I believe it's a bug and I'm not sure if Gigabyte will fix this.


Anyways, I'm satisfied with my E8400 @ 8x500 at ~1.3V.

[radaja]

simpletech,i had the same problem when i got my 9650.strap 333/240B would not boot.wasnt a problem with board but with the bios.with my e8500 i was alway on biosF5 pretty much the whole time and never had problem with 5:6.was even able to go as his as 560fsb with 333/2.40B 5:6.my strap issues started when i got my 9650 and flashed to F6 and then to F7 bios's.once i flashed down to F4 no more problems.so maybe give this a try.cheers.

i'm testing for max fsb on a quad, and priming at 500fsb right now with very little tuning. gotta say, i'm pretty impressed so far. the memory also only needs 1.8v for 1000mhz. here's my settings:

could a bad power supply cause my buzzing on my board?

If you're pc is stable don't bother, the sound your hearing is normal you probably have your fans off, turn all of them on and you won't hear the buzz anymore.

[bobreece]

If you're pc is stable don't bother, the sound your hearing is normal you probably have your fans off, turn all of them on and you won't hear the buzz anymore.

all my fans are on i have an antec 1200 and its whisper quiet got new psu on the way anyway i blagged a new modular Enermax Revolution 85+ 1250w.

the buzzing on my board goes away nearly if i disable llc. not bothered about it now guys just want to know if it will be safe?

[SimpleTECH]

cuz does any one have the NB under water ?

I currently am using a EK NB/SB 5 chipset block on my northbridge. Helps temps somewhat (I still get 40°C+).

[DOM.]

so how did you keep the hs on the mofsets on when taking off the NB off

does the heatpipe come off

[ChuckM]

Finally got everything and now have a bad stick of ram, got it running on 1 for now, haven't tried to OC yet but so far I'm really pleased. Haven't even messed with ram voltages but I don't think that will help my faulty stick, board won't do with that stick installed.
