It is in your BIOS. I would get online to help but going to bed.
Maybe we can do it Wednesday?
First and foremost, few weeks back, several websites leaked the news about a part called GeForce GTX Titan LE, a board based on cut down GK110 GPU silicon. The leak was right, since this will actually be a consumer version of Tesla K20C, the 2496-core part with 5GB of GDDR5 memory. The name will not be the GTX Titan LE, though. Meet the GeForce GTX 780 5GB. Just as the GTX Titan was a consumer version of the K20X (2688-core part, 6GB GDDR5 memory), K20A/C is getting a consumer version as well. The performance is about 30% faster than a single GTX 680. You can expect this board to launch (hard launch, availability from Day 0) in the final days of May, as the Computex train starts to heat up. Pricing unknown, but you should prices anywhere between $499 and $599.
