What I tried to underline is that:
a) I have no idea what caused my Saturns problems, my Jupiter running on the same line and same PSU type was not affected
b) The Saturns came with all boards affected by die #0 issue, (same as my Jupiter), they are running with die #0 off on 0.98
c) Both Saturns ran pretty well on 0.98.1 beta, one of them easily powering all dies, the other required more heat and was really hard to keep all dies powered on
d) Once 0.99 was released, i switched all my machines to it and for a day or two, they were running the same as on 0.98.1 beta
e) All of a sudden, both Saturns became affected with disabled cores, but in a different way: one of them simply has all cores disabled at startup (and keeps them like that) on 0.98.1 beta or official and 0.99. The other one starts normally, but after a while almost all cores on the same ASIC (coincidence?), the lower one on the web interface, gets disabled, only 0-5 cores remaining enabled on each die. Again, disabled cores are present on just one ASIC, the lower one in the web interface page.
This started at a day or 2 after 0.99 and the problem remained even after hard reset and affecting 0.98.1 as well, beta or official.
f) Both Saturns run normally (with their die #0 issue) on 0.98
My guess was that 0.99 FW somehow caused this issue, but it just persists now on 0.98.1 as well.
While upgrading my Saturn, I too ran into issues and now one of the new boards and one of the old boards are completely dead. All dies and cores report off. Enable cores doesn't work, all firmwares: nothing, plugged PCI-E straight into board: nothing. Most likely an RMA issue, and a PITA, to boot. Running their diagnostic shows all dies are idle. Don't want to risk 'heating' them up because I don't want to risk the electronics if I have to send it back anyways. I'm out of options unless anyone here has a method that brought back a dead board. My bertmod output is:
Its pretty much the same for the two failing boards. Different ports make no difference.
