XFX 780i SLI Motherboard
IO and BIOS
The I/O panel on the XFX 780i SLI provides a decent amount of connectivity with:
* PS/2 Mouse connector
* PS/2 Keyboard connector
* Firewire port
* 6 x USB ports
* Digital Optical out
* 5.1 surround sound analogue output
* Dual Gigabit LAN
It feels like there's something missing, perhaps an e-SATA port or two and maybe coax out and optical in for an SP-DIF pass-though, but these are all add-ons that add extra money onto the board and not everyone is going to have them on their wish-list.
XFX have gone with the Pheonix AwardBIOS for their 780i BIOS configuration which isn't too bad to navigate around, although you do have to remember that the overclocking settings are in the "Advanced Chipset features".
Adjustment wise the useful settings are:
|CPU Multiplier||x6 - x50|
|FSB Frequency||400-2500 (keyable 1mhz steps, quad pumped)|
|PCI-E Frequency||100-150mhz (1mhz steps)|
|RAM Frequency||400-2600 (Keyable - 1mhz steps)|
There's a whole load of options in there, plenty enough for even the most extreme enthusiast to rave about.
|CPU Voltage||0.5v-1.8v (0.0500v steps)|
|CPU FSB||1.2v-1.5v (0.1v steps)|
|Memory Voltage||1.8v-2.5v (0.25v steps)|
|nForce MCP||1.5v-1.75v |
|nForce SPP<-->MCP||1.2-1.55v |
|nForce MCP Auxiliary||1.5v-1.7v |
|CPU VTT Voltage||1.2v-1.55v|
|GKTVREF (Lanes 0-3)||+0mv - +160mv|
As you can see there's a large amount in this BIOS. The only disappointing voltage adjustment I thought was the memory topping out at 2.5v, although for insurance purposes I have to say that any more than that will make your RAM implode and Nvidia will come and get you....probably.
