So I discovered one of my hashboards died last night on one of my two X10's. These are from the $1600 batch at end of May/start of July (5/26).

I noticed my hash was low on one rig consistently and it was only getting 3-3.5 GH/s on Skein; so I pulled up the web portal and noticed one hashboard was reading 49*C while the others were 35*C like normal. This 3rd board was actually submitting shares and and DOES somewhat hash; but only at 10% the speed of a normal board. So if the two other boards submit 50 shares the bad one will put out 3-5 maybe.

I soft-rebooted the miner a few times and the temp no longer gives any reading other than 0*C (wonder if it burned up?) I contacted support and since I'm just about 3 months old i'm out of warranty and pretty much SOL :/. I talked to a friendly tech on the phone who suggested I take it apart and switch the hasboards around but to no avail. They offered to sell me a new hashboard for around $300 or a new unit for $900 with $92 ship (so basically full retail for a replacement board).

The miner can still run with 2/3 of the hashboards but for a barely 3mo old unit @ $1600 + ship there's no way i'll ROI with only 2 boards and 3 GH/s.

I will take off the heatsink of the bad board later today and inspect for damage; I didn't see any when swapping the boards last night but I suppose it would most likely be under the heat sinks if there was any.

I got something like this with the hash board. It didnt recognize all boards.

Try to take off PSU for at least 30 minutes. Unplug all connections, clean it with air (sry dont know the right word) from dust and then put it all together. Sometimes there is a mini gap and this causing some shit.

Maybe you switched SD cards for new algos and left a gap.

Also be aware of ESD you have to use gloves or use other things to connect to the ground. Otherwise you may killed it by yourself at switching sd cards.

At the end you have maybe to switch off the whole power up to 5 times until all boards are shown correctly.

I was about to order parts from them but got it this way working 2 times. One of my four is a little bitch, all other working fine.
