Features
With the relocation of the memory controller from the northbridge to the CPU the performance differences between two competing X58 motherboards are now going to be infinitesimally small. This is a phenomenon that we have observed on the AMD side since they made the switch to an integrated memory controller, and it is undoubtedly going to apply to the Intel Core i7 platform. As a result, manufacturer-specific features and overclocking capabilities are going to be the deciding factors when choosing between two similarly-priced X58 motherboards. As mentioned previously, the EX58-UD5 is the second most high-end X58 model in Gigabyte's roster, behind only the overclocking-focused EX58-EXTREME, therefore we fully expect it to be a technological Swiss Army knife.
Let’s take a closer look at some of the included features: Triple Channel DDR3-2100+
 The Intel Core i7 processors feature an integrated memory controller and a triple-channel DDR3 memory interface. To be take advantage of these new performance-enhacing capabilities features, the EX58-UD5 supports DDR3-2100+ memory speeds, even while the 6 DIMM slots are occupied. | 3-Way CrossFireX & 3-Way SLI
 The most exciting feature of the GA-EX58-UD5 is 3-Way CrossFireX and 3-Way SLI, which is a capability that enthusiasts have been waiting for on forever on an Intel chipset. In order to support SLI, motherboards must first be certified by NVIDIA, and Gigabyte have wisely chosen to do so with three of their X58 models. | Ultra Durable 3
 As we have come expect from Gigabyte, the EX58-UD5 utilizes the new Ultra Durable 3 technology. As with Ultra Durable 2, this signifies that the motherboard was designed with high quality and energy efficient components, namely Low RDS(on) MOSFETs, ferrite core chokes, and long-lasting solid capacitors. However, it also features an industry first 2 ounce copper PCB delivering lower system temperature, improved energy efficiency and enhanced overclocking stability. | Dynamic Energy Saver Advanced
 The new Dynamic Energy Saver Advanced provides better energy saving capabilities and most importantly it actually works while overclocking, which is something that competing energy saving solutions do not support. Finally, we can all benefit from maximum power savings and maximum system performance, the best of both worlds. | DualBIOS
 Providing bullet-proof BIOS protection, the EX58-UD5 has 2 physical BIOS ROMs which permit instant recovery from BIOS damage or failure due to viruses or improper BIOS updating. | High Velocity 2X Bandwidth Boost
 The Dual LAN controllers support Teaming functionality allowing 2 single connections to act as 1 single connection for twice the overall bandwidth. Also, they prevent network downtime by transferring the workload from a failed port to a working port. | EasyTune6
 Historically, the majority of manufacturer provided utilities have been quite poor. It is due to this undeniable fact that Gigabyte redesigned EasyTune6 from the ground up to make it easier than ever to manage, monitor, and tweak your hardware and system settings. | Onboard Quick Switches
 Befitting its high-end roots, the EX58-UD5 features onboard Power, Clear CMOS and Reset buttons. which are an undeniably convenient feature, particularly for those of us who operate our computer systems without a traditional PC case. | Hardware Overvoltage Control ICs
 Catering to the enthusiast crowd, the EX58 series features hardware overvoltage control ICs which allow for linear real-time voltage control options for the CPU, memory, and northbridge. In addition, these ICs also allow for extremely accurate control, allowing overclockers to perfectly adjust voltages in precise 20mV increments. | Visible Overvoltage Reminder
 This motherboard features an embedded post code debug LED display, which indicates if a malfunction is occurring and allow users to quickly identify the source of the problem. Secondly, it indicates system power status, preventing potential hardware damage due to improper installation/removal of components while the systems is still in a power-on state (S0, S1, S3, S4, S5). | OV-Alert LED
 The 4 sets of OV-Alert LEDs indicate the overvoltage level of the CPU, Memory, North Bridge and South Bridge to prevent component damage. | Visible Overclocking Reminder
 The OC-Alert LED indicates the degree to which to your CPU is overclocked, ranging from low to high, which might be useful for novice users who likely should not be overclocking to begin with.
| Visible Temperature Reminder
 Gigabyte has outfitted the EX58-UD5 with 2 sets of Temperature Alert LEDs. These LEDs serve to inform users about the current temperature level of the CPU and Northbridge, which should be a useful novelty feature for novice users. | Dolby Home Theater®
 The EP45-UD3P features an 8-channel high-definition audio codec chip that supports Dolby Home Theater, which is designed to automatically deliver the best possible surround sound listening experience no matter if you're using two to eight speakers or simply headphones. |
