Excellent motherboard for its price, buy it with all trust, worth for every buck, nice components and conectors distribution, thats my second gigabyte motherboard.

sadly i m from South America and i can't be sending back this product, the motherboard at first got a veeeery slow booting, it said detecting IDE drives, for like 30 sec, then one more time another 30sec, then it did boot, i had the chance to install the OS restarted and then it didn't boot ever again, the IDE port was magically burnt, i tried with different ide drives and configuration slave cs mstr, etc etc and nothing, then bought some SATA drives and they booted but as slow as the first time, still working on it, working on the bios, but soo far nothing... even some modifications at the Bios don't let me get back to the bios, the mobo gets freeze while searching for IDE drives even if the ones i got plugged are sata. i don't' even bother asking for refund because just sending the mobo back to US is the same cost as buying a new one. probably a good mobo unless you don't have as bad luck as i.

2 days later, i got 2 sata drives, one dvd burner sata, and a 160gb sata HDD, i did turn the IDE/SATA off on the bios, and the mobo finally booted fast and without mayor problems, i will run some tests to see if there is any problem on the reading or writting in both drives, will post soon the results if any of you have this problem feel free to contact me.
i would rate this item now up to 3 stars the thing is that i cant edit that rate....

Motherboard looks great.Booted up with no bios adjustments.As a note,if you use a usb keyboard,usb keyboard needs to be turned on in the bios.Driver disk has all the goodies you would expect.I installed this mobo and a q 9550.It booted up and installed Windows 7 64 bit first shot out of the box.Great board for the price range.

I bought the EP45-UD3P with a 3.0Mhz Intel 8400.

First it had some sort of startup delay where the fans kick on, then off, then on again. Then it boots up fine. After one month use, it stop booting at all.

Funny thing is that with a Celeron processor installed in the MB it still boot.

My Intel 8400 is now working fine in an ASUS MB. Something burned inside the Gigabyte MB, so it still work with a slower processor, but never again with my 3.0 Mghz Intel 8400 (not so fast anyway, but too fast for the EP45-UD3P...).

I bought this motherboard as an upgrade for a storage server. The previous mobo wasn't 64-bit compatible so I picked this one up as a replacement. I planned to drop it in, it would recognize my 4 disks (2 x 1TB RAID-1 mirrors) and all would be well.

After getting it all assembled, it booted up but 3 of my 4 disks were no longer recognized by ZFS. One mirror was degraded and the other gone entirely! :-( That's when I learned about this boards HPA 'feature'. When I powered the machine up, it repartitioned the disks at the BIOS level, stealing a couple MB off the end of the disk. That changed the disks geometry, and ZFS appropriately refused to recognize it (it stores superblocks at the end of the disk).

The solution was to reboot onto a special CD with a HPA util which allowed me to remove the HPA partitions (a tedious process requiring power cycling the disks). Since this MOBO doesn't provide a way to disable HPA, the only solution is to connect them to SATA ports that aren't destructive. And remember to NEVER, NEVER, NEVER plug my disks into the on-board SATA ports. :-(

Everything else about this board is just fine, but the HPA feature cost me many hours of wasted time. The MOBO manual describes a BIOS feature that doesn't exist for disabling HPA. I've found others who experienced this issue. It can cost far more time and effort than the board is worth. You've been warned.
