Gigabyte's GA-EP43-UD3L motherboard has been optimized to work more efficiently with 45nm processors. The board has dynamic 4 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.

Boasting Ultra Durable 3 technology, the Gigabyte GA-EP43-UD3L comes with the industry’s first consumer desktop motherboard design to introduce 2 ounces of copper for both the Power and Ground layers, delivering a dramatically lower system temperature, improved energy efficiency and enhanced stability for overclocking.

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. Get the Gigabyte GA-EP43-UD3L today and build you own high end system.

Motherboard worth having

Pros: Most times there are troubles with new Motherboards. I bought this when it was fairly new, and other than a flash update of the bios, I've not really needed to do more.
It's always had room to fit what I needed and never a problem.

Cons: none

Other Thoughts: I've used this board for a while now, updated the cpu twice and it's never complained. I"m use to MB's becoming unstable after 2 or 3 years but this has held yup great. I think the caps are as good as Gigabyte says. this machine runs 24 hours a day for 3 years. Sans reboots and upgrades.

Excellent Board

Pros: Good value, plenty of USB and SATA connections. good On-board Audio and gigabit ethernet, latter of which saved me a PCI slot when I originally built it. Long-lasting- using it as I type this, was part of this build I did around 3 years ago and has been a solid performer since, which room for expansion both with more drives as well as expanding the memory from 8GB to the Motherboard maximum of 16GB.

Cons: somewhat obsolete (it is 3 years old). Only 2 PCI slots, which could be an issue if you have a nice collection of PCI cards you plan to leverage.

Other Thoughts: 100% satisfied with this board and it's performance over the last 3 years. Stable and reliable, it's been a component I can rely on.

Terrible board

Pros: Supposedly met all my requirements to run Intel quad core extreme type chips for a media PC

Cons: Just didnt work. Didn't turn on. Spent a lot of money taking it to Fris electronics, Best buy geek squad and also sent it back to Gigabyte for repairs but all of them failed to fix whatever defects in this board! Very bad!

3 GB boards, = 3 dead GB boards

Comments: I've given Gigabyte 3 chances, but there products (motherboards) have failed me every time.

Great Warranty but who has time, it's not worth the wait! Customers will not wait, so you have buy another brand. I think Gigabyte depends on this fact.

Watch Out

Pros: None at all

Cons: I had trouble with this board starting only 2 weeks after I put it in. My computer would not boot up only set there and beep non stop till I manually shut it down. I was told it was a connection problem but after scrutinizing all the connections the problem persist. Now only 3 months after I purchased the board its totally dead and has to be replaced. HOW ABOUT THAT FOR QUALITY!

Other Thoughts: I see Newegg no longer carries this board, hummm I wonder why?

DOA and Tough to RMA

Pros: Wish I knew

Cons: Bought this to replace an older Gigabyte board that had died. I got this board and then took me awhile to get it installed due to holidays and work. By the time I got it in and found it was DOA outside newegg's timeframe and after spending 8 hours over the course of a week wading through various hold music and emails trying to RMA the stupid board gave up. For the time I wasted I can just buy a new board and will just now buy someone else's motherboard instead since GIGABYTE gave me such terrible service.
