The GIGABYTE X58A-OC is the world’s first motherboard designed specifically for overclocking. Bringing several new technologies together for the first time in one motherboard, the GIGABYTE X58A-OC has all the features overclockers have been asking for, making it easier than ever to take down world records. Powered by the Intel® X58 chipset, and supporting high-end Intel® Core™ i7 CPUs including the record-breaking Intel® Core™ i7-990X Processor Extreme Edition, the GIGABYTE X58A-OC is able to push past performance boundaries maxed out by other platforms by offering native 4-way graphics support (CrossfireX) and triple channel DDR3 memory support. It’s unique layout design further increases performance potential by following the shortest pathways between key components such as the memory and CPU (for minimal latency), wider CPU zone and low profile components for easier extreme cooling insulation, memory slot spacing that doesn’t interfere with graphics card installation, and a grand total of 7 four-pin Smart Fan controllers that allow overclockers to precisely adjust fan speed and control system temperature, just to name a few…
The GIGABYTE X58A-OC features a new VRM design called OC-VRM, which includes a combination of highly conductive POScaps, 50A rated MPFC (Max Power Ferrite Core) Chokes, and Driver-MOSFETs, which combined, are able to deliver higher current to the CPU, with better efficiency and lower temperature. OC-VRM also allows users to overclock the PWM frequency via an onboard switch, for real-time adjustment. When the CPU needs maximum power, users can raise the PWM frequency in order to deliver more current through this unique POScap and MPFC Choke design. In addition, GIGABYTE has specially chosen unobtrusive components and carefully designed their layout to make it easier and quicker than ever for extreme overclockers to insulate their boards.
Quicker and Easier to Insulate
Output up to 1200W
IN-PUT up to 1500W 2x 8Pin CPU Power Connectors
Powerful: Low temp Single Choke Up to 50A
Fast: Durable Entire Board with Poscaps
Intersil Overclocking PWM
Quick: Real-time Overclock PWM frequency to 600K/800K/1000K
OC-Touch enables overclockers to quickly and easily get the best performance from their system. With onboard OC-Touch buttons, users are able to manually raise and lower the CPU ratio, change BCLK settings, and even change BCLK stepping to either 1MHz or 0.3MHz. These changes can be made at any time whether in the BIOS, DOS, or Windows and in real-time without the need for rebooting, so that users can quickly fine-tune to find their CPU’s maximum frequency. The onboard 4G Ready button allows novice overclockers to automatically reach 4GHz, while advanced users can use it to get to 4GHz before continuing with OC-Touch to quickly find their CPU’s best margin. Onboard voltage measurement modules are also included to help users to conveniently monitor component voltages.

Dual CPU Power
Imagine a workstation class redundant (duplicated) power design on a desktop motherboard! GIGABYTE’s proprietary Dual Power Switching Technology allows CPU VRM power phases to split* evenly into 2 sets of power engines that operate in tandem. This allows 1 set of power phases to rest while the other is active as opposed to a traditional power design where all the power phases are always active. So GIGABYTE Dual CPU Power effectively halves the amount of work done by each set of power phases to significantly increase motherboard durability and reliability.
Power Phase Boost with Multi-Gear Switching
GIGABYTE X58A-OC motherboard also features Power Phase Boost with Multi-Gear Switching.** This operates both when Dual Power Switching is active and when it is not.
Normal Loading 6 Power Phases are active with Dynamic 6-Gear Switching
Heavy Loading Full 12 Power Phases are active with Dynamic 6-Gear Switching
**Multi-Gear Switching requires system to enable GIGABYTE Dynamic Energy Saver program. The number of power phases for each Gear switching may vary between models.

333 Onboard Acceleration
GIGABYTE 333 Onboard Acceleration motherboards set a new standard in high performance computing by incorporating all the industry's latest high-speed data transfer technologies. Proving once again to be the true Leader in Motherboard Innovation, the GIGABYTE 333 Onboard Acceleration delivers unparallel performance with onboard integration of the latest SuperSpeed USB 3.0 technologies, SATA Revision 3.0 (6Gbps) technologies, and an unprecedented 3x USB power boost on all USB ports for the most power hungry USB devices.
USB 3.0 10x performance is a maximum theoretical value. Actual performance may vary by system configuration.
SATA3 RAID 0 4x and SATA3 2x performance are maximum theoretical values. Actual performance may vary by system configuration.
3x USB power is a maximum theoretical value. Actual performance may vary by system configuration.
On/Off Charge Technology
GIGABYTE On/Off Charge technology allows you to charge your iPhone, iPad and iPod Touch regardless of whether your PC is on, in standby mode or even off. A derivative of GIGABYTE's highly acclaimed 3x USB Power feature, On/Off Charge enables devices to draw more current from GIGABYTE motherboard USB ports than standard USB ports allow, so that charging from your PC can be as fast as with a charger.

This board is the coolest board I have ever had the pleasure to build a PC with. Previous to this board I think the generally accepted "best bang for the buck" of mobos was the EVGA 750i FTW board, and that's what I replaced with this tank. Sure it doesn't have Firewire or good onboard sound or a lot of USB ports, but who cares? You can add all that stuff, this board looks, feels and performs like a quality board should. You can tailor it for your needs, and it has nothing you don't need. The main problem is of course the fact that it's a 1366 socket. That and it's crazy expensive when it's not on sale. I lucked out and got it for $149 after a $50 rebate, and even though I forgot to mail the rebate in time I would totally buy this board for $199 again. When was the last time someone was OK with not getting the rebate? That's how nice this board is!
I have this paired with a 990x which i overclocked to 4ghz using the 4G button and its very stable unlike the last board i had which had a setting for a 4ghz overclock but wasnt stable at all.
