Hopefully, bluestreak66 was saying the chips have a theoretical max of 1GH/s and that around 750MH/s would be the limit of these boards. So hopefully I can get these higher frequencies going with water cooling and decent power supplies. More for fun than profit of course. I'd like to think I can get the BE's to pay for themselves in a year and they'll need all the help they can get.
I had mine strapped to a heatpipe cooler, with the soldermask removed and the silicone sheet in between they were running quite cool at 447. Given the shortage of avalon chips right now these might just turn out profitable!

I am quite curious why your only getting 360Mhs that seems low to me.
