I received the cube the other day and I realise that there are 8 chips marked with an "X". I assume these are faulty? Overclocking is not used. Anyone with the same problem?

Hey mate,

An "X" chip does indicate a faulty chip, does restarting the cube help at all? can you send me a screen shot of the web interface.

I found that cycling the power from On to Off does eliminate the half row of X's marked as bad. What I realised is that the same set of chips was not affected and other chips would be affected. As I decommissioned my FPGA's that use more power just to check to see if it isn't the ASIC cube, it seems to be working OK.

I think it is the case that the PSU is not delivering enough amperage to cover all devices but I will confirm as I monitor it overnight.
