Gigabyte has released a new BIOS for its GeForce GTX 670 WindForce 3X graphics card (model: GV-N670OC-2GD), which has been available for a few months now. The BIOS solves a possible stability issue that is caused by an error in the addressing of overclocked GDDR5 memory chips by Hynix. The manufacturer has released two new BIOS revisions, one based on the original Nvidia BIOS with version number 80.04.31.00.58 (F4) and another based on the original BIOS with version number 80.04.31.00.09 (F12).
The two BIOS revisions are dated July 13th but have only been recently been published, Techpowerup says. The new BIOS revisions don't change the specifications of the GTX 670 WindForce 3X card. The core clock frequency remains 980 MHz with a 1058 MHz Boost frequency and an effective memory speed of 6008 MHz GDDR5. Apart from an enhanced cooler, the GTX 670 WindForce 3X also has a larger PCB, which was borrowed from the more expensive GTX 680 card. The card has a more powerful VRM power design, potentially providing a larger overclocking potential than the reference PCB of a regular GTX 670 GPU.
The procedure of flashing the card's BIOS is explained on Gigabyte's website. It has to be noted that flashing a graphics card is at your own risk and is only recommended when stability issues occur.
