SLI and/or Crossfire

The G1975X offers two PCIex 16X slots currently supporting mutli-GPU rendering aka ATI's CrossFire technology. The board may also support nVidia SLI, may be indicative of wishful thinking or perhaps something more substantial. DIY Enthusiasts are most likely exploring this option as you read.



From another angle we see all PCI slots and the creative Sound Blaster chip as well. On the side of the black PCIe slot I made an interesting discovery.



Three Atmel ATF16V8B PLDs are located just below the second PCIe slot? While there are multiple uses for these Programmable Logic Devices or clocks, I'm sure their not used as EEPROM or CMOS related? I'm waiting on an answer from Gigabyte which will be edited into this page.



We see the 2x4 motherboard power-supply connector, specifically designed to meet the increased current demands of Intel multi-core processors.



Intel doesn't endorse overclocking it's CPU's therefore manufacturers are left to their own "devices" in-so-far as power conversion circuitry and other related devices. Gigabyte shipped the G1-Turbo with a plug in the 24-pin connector and a plug in the 2x4-pin connector. Ironically many Overclocker's are pulling their 20-pin PSU's out of storage discovering high amperes on the 12V rail seem to be ameliorating instability on Multi 12V rail PSU's which can run as low as 15A.



Gigabyte's signature Dual BIOS has been an original feature found on models at least as far back as the Socket A/462 era. In and of itself the Dual BIOS feature assist PC-Enthusiasts whom continually flash their BIOS as new versions become available. yet this board isn't atypical Gigabyte and another feature I've only found on DFI boards defines the G1975X as a true DIY product.



For those Enthusiasts whom often test their boards outside of the case, or for the End-user whom favors the recent trend in "Open Chassis" cases, Gigabyte has provided an option I've only found on DFI boards until now. Gigabyte has placed two manual "spring-loaded" buttons, one Red for BIOS re-set, and the other Blue for power-on/off re-set located at the "bottom" of the board.
