Yeah, we're not quite there yet. Given some of the rumblings I'm hearing 1GHz might be a case by case basis, like hitting 5GHz on an i5-2500k. Some can get there, and some can't. Part of our profiling process is getting the exact mix right. For instance right now I'm running at 912MHz, and one die is marginally stable at my current frequency/voltage settings. The other dies can do better. Once FW and SW support gets to the point where we can decouple the dies and run them each with a separate frequency and voltage, we should be able to extract more from the chips.
