One of my blades started spitting out thousands of hardware errors per second at the stock 600 MHz clock so i did the usual test points to see if there was a fault on the board (https://bitcointalk.org/index.php?topic=576784.msg7330855#msg7330855) and there was not fault, everything was fine, i don't get it, why did the board suddenly start having so many hardware errors, does anyone have an idea of what's going on?
