I'm a friend of Liquid Shadow who told me to post my new build info here to see if you guys have any thoughts. As he can probably testify, I've been dying to order the parts for a new computer but the more reading I do on various motherboards, the more confused I get - and that makes me more indecisive.

So, this is the final build I was looking at:

Intel Core 2 Quad Q9400 Processor
Gigabyte GA-EP45-UD3R Motherboard
G.Skill 4GB (2x2GB) DDR2 1066 RAM (5-5-5-15)
Win XP

I am going back and forth between the Asus P5Q Pro and this Gigabyte board. I intend to be using my computer to do general computing work (word processing, email, AIM, etc), light photoshop use, video editing with Sony Vegas Pro, and work in Pro Tools for audio recording (and with other audio apps).

I have been reading on the Digidesign forum about how "amazing" Asus is, and I currently have an Asus board that has run fine so the logical choice is to stay consistent, but I love the placement of the onboard connections on the Gigabyte more and the reviews I have read seem to favor it a great deal over its predecessor. Plus, I have no use for 2 pci-express ports that the P5Q Pro has, so gaining an extra PCI slot on the Gigabyte (not to mention all the USB ports and 3 firewire ports).

As expected, the loyalists out there make this a tough job. For every favorable review about an Asus board I see an unfavorable one and the same goes for Gigabyte. Newegg has lowered hte price on the P5Q Pro this morning which would reduce the cost of my build but it's not about money it's about whether or not I will have problems with it on day 1. Many people complain about DOA and after tons of computer headaches in the past, the easier I can make this on myselft the better.

So, does anyone who uses this board have an issue with it (and same with the P5Q Pro) - what do you guys recommend I do in this case? Stick w/ the Gigabyte or go to Asus?

I am in kind of the same boat as you. I was set on getting one of the "spankter" evga new boards. There layout is so good and many good and bad reviews. I serched for about 1 week just trying to find the perfect board. Then i came across this review. I dont know if you have read it but here is the link.

This is my first gigabyte board. I was normally an msi kind of guy but with the little quirky problems that all 3 of my previous msi boards had i was thinking of switching to asus or evga.

My processor comes in in 3-4 hours, so i havent built the system yet, but i have had the ud3r board in my hands for a few days and i have fallen in love with it.

1.I like the external esata. My friends are always asking me to test there sata hdd and this will make it a lote more simple.
2.i needed 6 or more sata, now i have 8 internal and 2 external. with 2 placed for my dvd writers :)
3. I needed 6 usb external in the back. I now have 8 plus 4 in the front, though my case only has a place for 2 :(
4. the large north bridge heatsinks is a plus. I would have perfered a fan on them, but there large enough to cool as is.
5. It has the 8 pin cpu power connector also the atx 24 pin is in a good position.
6. the ram is far enough from the cpu to be able to install ram with large heat sinks, or a large heat sink on my cpu.

The only thing that i dont like about it is.
1. It only has one "lan" but the sli/crossfire board has 2 lans.
2.the fdd is on the side of the board rather then back by the ide.

After reading the dit-tech review, and seeing the good pics they had, also how this board had been refined over its earlier models, i couldnt resist. also saving about $100 was a plus too.

As far as personal experience and seeing the preformance of the board, i dont have any, just keep that in mind. Hopefuly we can get someone to post here that does have the boards as i am curious also.

I've had the subject motherboard for a couple of months now. I know saying this might put the King's X on me, but I've had absolutely no problems, quirks, bugs, snags, etc. with it. The BIOS is overloaded with settings. Most I'll never use, but it's like having 600 horsepower under your hood. You will seldom use it but it keeps a smile on your face.

>> Re: Gigabyte GA-EP45-UD3R Questions
instead of those two boards i would recommand the asus p5q-e or the gigabyte ud3p.
both counter parts to the asus p5q pro and gigbyte ud3r are just a tad more expensive but certainly worth it.
i would rather step back from the reviews and pick what really suits you better. both are very good and matured in their bios's. if you overclock you can achieve 450 FSB and up to 500 FSB on both boards.
i have the p5q-e and i am very happy with it but i was going back and forth with it and the ud3p. i choose the asus because i believe that will have use for the extra pci-e slot at a later point in time.

You can either be part of the problem or be part of the solution.

Emeric and Micro

Like Restring...... I too have had absolutely NO problems with this motherboard from the time of the first power-on (fire in the hole!!!!) up until now, which has been 1 month running.

I just finished building my new system in the month of Dec. I'm hoping to post some pictures of my build soon to share with you all... here are my new specs:

Gigabyte GA-EP45-UD3R
Corsair Dominator 4GB (2x2gb) DDR2 1066 5-5-5-15
Sapphire 4870 1gb w/non-referrence cooler
Creative X-Fi Titanium PCI-e
2 x 640gb WD6401AALS Black Edition 7200rpm 32mb cache
2 x DVD+rw burners
floppy/media reader
USB/Firewire Combo card PCI
Coolit Freezone
OCZ 700W GameXtreme psu
Vista Enterprise x64

In relating to the mb. I have had absolutely no problems or quirks with it. It identified the cpu and my Corsair Dominators 1066 without any issues. Like you, I debated about if I should go with the UD3P with the two PCI-e 16X for future Crossfire setup, BUT decided to go with the UD3R because in the end I would rather get as much gpu power as I can and then down the road if I need a newer gpu I would get the best I can afford at that time. Plus, I wanted to keep it simple and not wanting the extra complication of a second gpu card. If anything I would probably go with a dual gpu on a single card over a dual card setup.

Additonally, as you recognized, by going with a single PCI-e 16x..... you get an extra PCI slot which I would believe you will come to use first before a second gpu card. The placement of all of the connectors onboard and rear panel is near perfect... with the exception as Micro mentioned is the floppy being located on the back 40 field. I really like the 8 USB and including the 2 PS2 ports on the rear panel. When it comes to heat generated by the South/Northbridge or Mosfet heatsink...... I will tell you... it is practically NONE... at least it is barely lukewarm on the northbridge and the mosfet are actually cool to the touch. Not sure if this is due to the newer design of the motherboard or the benefits of the 2.0 OZ copper layer in the board. But whatever it is, this board runs cool... UNLIKE my brother's Gigabyte GA-EP45-DS3L where the northbridge and mosfet runs extremely HOT..

So far, I have had no issues with any items in BIOS. When it comes to memory.... originally with this motherboard, I had order 2gb (2x1gb) Kingston HyperX 1066 5-5-5-15 and then later on I decided to replace them with Cosair Dominator 1066 5-5-5-15. The Kingston when first powered up, the motherboard recognized it as DDR2 800 and I had to manually set it to 1066 and it's rated timings.. BUT when I replaced with the Cosair Dominator 1066, Bios recognized it right away as 1066 in auto mode but the timing was a little bit loose... I manually set the timings to its rated 5-5-5-15. Both memory, I am running it a 2.08V stable and both runs extremely cool with leary a tad of lukewarmth to them.

The only "Real" heat inside my case is bleeding of the sinks on the Sapphire 4870. Currently the 4870's temp is at 44C idle with the fan set at 40% in CCC. When gaming, the temps hoovers around 55C. The mb temp sensor says it is at 35C... and my cpu runs 32C idle with 42C gaming.

Bottom line is that, I am absolutely pleased with with motherboard. It is a very solid and stable board that I believe would be around for a very long time. As for OC'n.... I'm not an OC'r and have not tried clocking my cpu yet.... I am more for longevity and that is why I purchased as much cpu as I can so as I dont have to OC... but I do have the option if I want or need to. The only OC'n I have dipped into is with my Sappire 4870 1GB where I reached 835gpu/975mem (stock = 750gpu/900mem) just for giggles, but my clock settings is now back to stock for everyday usage.

I am certain that both of you guys will not have any trouble with it and will walk away very pleased with the performance of the board...

Thanks for all the feedback! I certainly feel more reassured about this purchase.

Okay, one last thing. I remember reading about the Gigabyte P35 boards having issues with DPC Latency. Does anyone know if this is still something that affects the P45 boards? How difficult is it it to fix ? It seems to me that there used to be quite a few issues with having to change tons of settings in the bios, etc.

Just one thing of note. Asus make great boards but they aren't known for great customer service if it comes to an RMA situation. I had 3 boards back from Asus that were refurbished replacements but unfortunately they didnt work.
I discussed this with the distributor and the retailer both of whom said unfortunately Asus were guilty of doing this quite often. 2 of the other desktops in this household have Gigabyte boards and they have had no problems.

>> Re: Gigabyte GA-EP45-UD3R Questions
I ran DPC latency tests on 2 of my computers that have Gigabyte boards. Here's the deal:

GA-P35-DS3R (F12 BIOS): 5 microsecond - average; 40 microsecond - maximum

GA-EP45-UD3R (F3 BIOS): 12 microsecond - average; 48 microsecond - maximum

I ran each test for 5 minutes. The average numbers are "ballpark" estimates from watching the readout (which is constantly changing) while the test was running. The maximum numbers are displayed during the test.

>> Re: Gigabyte GA-EP45-UD3R Questions
Hm. Thanks for running the test. Since I'm not going to be recording from the SPDIF on the motherboard (or using the onboard sound), I am hoping that doesn't prove to be a problem while recording. I use my recording interface as my main sound device - an M-Audio Firewire 410, so I'm hoping that, if I understand this all correctly, that by recording and listening back on my firewire device is going to not be affected by DSP latency issues on the motherboard. I'm really not all sure how that works, but if someone wants to correct me please go ahead.

I've placed the order for the board, the processor, and ram. I'll keep in touch with this thread and if it gets here before the weekend, hopefully I will have great things to say by early next week!

>> Re: Gigabyte GA-EP45-UD3R Questions
My test results are very low (good thing!), and the test software reported I should have no problems with my boards. As you noted, some earlier Gigabyte P35 boards had a problem with very high latencies (1000 microsecond and higher "spikes"), related to the Southbridge chipset. From what I know, it was a problem only experienced by Gigabyte brand boards.

>> Re: Gigabyte GA-EP45-UD3R Questions
Right, that's what I had read at all but from what I've seen in reviews there hasn't been anything brought up about that with the P45. I know it was just Gigabyte boards but I'm secretly hoping they fixed this in the P45 revision. Here's to hoping - I guess I'll notice when I try and record with it after I build it up and have everything reinstalled!

I'll go out on a limb and say you should have no problems. Good luck, or rather "Break a Leg". ;)

Haha, that he does. We went to Eastman together. He pointed me to the forums, I suspect, not only to get me help but because I was obsessing over this so much. This is my first large computer upgrade in several years...whatever, it's ordered now so hopefully it all works out the way I would like it to!

This DPC Latency thing... as you can tell I dont know whatcha talking about... but does this have to do with the onboard sound and with the optical input?

where can I get this test program and I'll try it out on my GA-EP45-UD3R...... To see if my results are the same as Restring's....

This is the site where I downloaded the program. It didn't raise any alarm flags or set off any bells, so I rectum it's safe:

It explains the whole concept and how to isolate what is causing high latencies, IF you are experiencing them.

Restring, thanks .... I just found it on my own (google our friend) and read up a little on it....

I downloaded the program to see what my system would do... but.... I just thought of something and in that my setup is going to be a little different as in I just remembered that I am not using the onboard audio.... it is disabled in bios and I had uninstalled all of the drivers for it.... in favor for the Creative Titanium X-Fi PCI-e..... but I went ahead and ran the program anyways..... the output is ~28 average and max ~ 70... The program did say that my system would have no problems streaming or whatever it was looking for....

>> Re: Gigabyte GA-EP45-UD3R Questions

when you get all your parts and start to build..... the first thing you want to do before you begin to install the OS is update your bios... it is very easy... just go to Gigabyte and get the latest bios, which is at F5. Mine is at F4 which was the latest when I built mine. Extract the bios and place it on a thumb drive.... power on the motherboard and go into bios and there is a utility, one of the f keys where it loads the bios from hdd but in this case it would be the thumb drive and away you go....

The order of install I did was - bios, OS, Lan, MS updates, chipset, video, and then sound.

best of luck..
