This is an XC5VLX110T-1FF1136 running at 120MHz. If you want to build a dedicated mining board, I'd suggest placing a shitload of XC6SLX150 chips on it, and much less unused peripheral stuff.
so, those chips are $152 each
what is the board to put a shitload of them on? Has anyone tried this with more than one fpga chip? does it scale fully?
