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.
I initially had a similar issue with FW 0.99.
This was my fix:
1. Try flashing FW 0.90
2. Do a hard reset either via KnC recommended 5 push/5sec/5push reset or
hold reset button about 30 sec until red light flashes
3. Pull power wait 30 sec and plug power back in
4. Enable-cores
5. Run for an hour or so despite speed not being ideal unless speed is nothing
6. Upgrade back up to FW 0.98.1 Beta
7. Hard Reset and Hard Power Cycle 30 Sec
8. If after rebooting and a hour of running speed does not seem ideal
run enable-cores(sometimes you have to rerun enable-cores multiple times, 3 seems the average for me)
(if after all 8 steps it doesn't work try again from step 1 using FW 0.94)
------------------------------------------------------------------------------------------
These machines are extremely fickle
sometimes requiring multi boots, resets, and FW flashes
to stabilize/optimize performance but
what do you expect with leading edge hardware and
would you of rather waited for more stable(tested) hardware and lost significant profits..
