So i procured a KNC Titan (4 cube) with controller board and PSU's recently. Got around to hooking it up today and cannot get the controller board to post. The screen illuminates on the controller board but does not show anything even after 5-10mins. No ethernet activity coming out of the rPi. Tried a few sd cards with stock 2.00 FW flashed to them. To no avail I cannot get this thing to post. All cubes fans start spinning. I am suspecting a bad RasPi board. Going to try and swap soon to see if that helps. Was running great last week at a steady 350mh/s in the hands of the past owner.
Strange note: When the MOLEX to 6-pin connector is in one of the PSU's it seems ok and I get the above as a result. When its plugged into the 2nd power supply the PSU shorts and wont turn on until unplugged.
Anyone with Titan exp let me know if you have seen this before. Thanks in advance.
