Gigabyte has long been a leader in energy-saving motherboards and their GA-EP45-UD3P motherboard continues the trend. This board features 6 gear power switching. As your system needs more power, it gets it, and when the power load goes down, so does the supplied power. This lets you have power when you need it, and save energy and money when you don't.

Based on Intel's P45 Express and ICH10R chipsets, this ATX board is ready to host the latest LGA775 Core 2 Extreme multi-core processors along with Core 2 quad-core, Core 2 Duo, Pentium D and Celeron CPUs. Up to 16GB of DDR2 1366+ can be installed providing increased performance. A pair of PCI-Express 2.0 x16 cards can be mounted for cutting-edge graphic power with support for CrossFireX.

System durability and security are as important as ever. Gigabyte's DualBIOS system has a second BIOS chip on the motherboard for quick and painless recovery from crashes and viruses. Count on Gigabyte's experience and innovation!

Intel P45 Express Chipset for Intel LGA 775 CPU Based on the Intel P45 Express chipset, the Gigabyte GA-EP45-UD3P supports Intel LGA 775 (Socket T) processors including the Core 2 Extreme, Core 2 Quad, Core 2 Duo and Pentium D series as well as the next generation Intel 45nm processors.
ATi CrossFireX Multi-GPU Technology Support ATi CrossFireX is the ultimate multi-GPU performance gaming platform, enabling two or more discrete graphics processors to work together for boosted system performance and a breakthrough gaming experience.
SATA II with RAID Support The second generation SATA interface delivers up to 300MB/sec transfer speed, doubling that of the first generation Serial ATA. The on-board eight SATA II ports support RAID 0, 1, 5 and 10 for better performance, enhanced data security, and flexible capacity upgrades.
Dual Gigabit LAN The integrated dual Gigabit LAN design allows a PC to serve as a network gateway for managing traffic between two separate networks. Dual Gigabit LAN means rapid data transfers from WAN to LAN without any added arbitration or latency.
Gigabyte DualBIOS Gigabyte DualBIOS technology protects the BIOS from virus attacks. With its innovative backup BIOS design, this platform provides twice the security thus assuring the PC’s stability.

N/A 9/6/2011 5:20:16 PM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 2/5I know it's too late to sway anyone Pros: This was a great board that did everything I wanted it to do or needed it to do while it worked. Cons: Two years into the three year warranty the board failed and after a dozen attempts to contact their support to get an RMA, I have given up with the decision to NEVER buy a gigabyte product again. Again, this was a great board while it worked, but if gigabyte won't support their products, then I'll take my money elsewhere. Other Thoughts: Gigabyte support is non-existent. 0 out of 2 people found this review helpful. Did you? Thanks for the valuable feedback you provided!

Falls PC 1/4/2011 8:18:05 AM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/5To bad it's discontinued Pros: Rock solid except one little thing (see other thoughts). Setup was easy. Plenty of USB ports, IDE ports and, well, read the details, it's loaded. I've had this over a year and love it. Cons: After about a year the second network adapter and 1394 stopped working. See other thoughts. Other Thoughts: After about a year of using this the second network adapter and firewire ports stopped working. I have a dual boot and they were out in both OS's. I was about to RMA it when I thought I'd just try a BIOS flash, nut'n to loose. I went with the FFb (beta) update and after I was finished everything was working again. I've read a lot of reviews on other sites of dual channel mem not working as well as other problems, but my board works fine and I'm happy to give it a 5 egg review. 1 out of 1 people found this review helpful.

alabama-redneck 4/6/2010 10:37:05 PM Tech Level: 3/5 Ownership: 3/5 Verified Owner	Rating: 4/5Good motherboard overall Pros: Compatibility with PS2 mouse and keyboard. Makes the system safer Plenty of slots for SATA disks and cards. Floppy disk slot avalaible. It is good, I had to use floppies to install FreeBSD. Cons: Missing the 2 IDE ports. No parallel and serial port. I need adapters USB -> serial. Windows XP is very hard to install on such a hardware (but doable) 1 out of 4 people found this review helpful. Did you?
