So how hard you guys think we can push these things? I would love to put them BFL folks in a competitive place if their hardware exists. With proper cooling, and well regulated power, whats the theoretical limit? I plan on buying one of these and water cooling it when my tax return comes this week, I will offer a bounty if someone can squeeze 500 M/hash out of these. (250 MHz each chip I believe)
You can see more in-depth conversation about trying to squeeze additional performance over at the ztex thread -- my read on it is that 200MHz may be close to the max you'll get from the LX150. There is a little noise about upping the voltage on the chips to try to get a tiny bit more performance (~4%) but it's a good way to blow the chip if you screw up.
