You can try this fix.
Note it's totally unofficial, but it's what appears to be working until we have some solid feedback on the test rigs over the next couple of days. Results may ramp up slow, and take upto 3 hours to see a solid performance, but it's brought several I have tested back to life;

Topic: KnC die #0 disabled - page 2. (Read 4121 times)
I thought this deserved its own thread.
I'm learning that a lot of the later shipments of KnC's miners have an issue where die #0 out of the 4 on each chip does not function.
This can be seen by installing BertMod and looking at the output current of the DC-DC converters. Affected units will show a much lower current on #0 than on the other 3.
I'm afraid I can't contribute a lot since I have an early Saturn that is not among the affected units.
There is a much better summary of the issue over on the KnC forums:

I thought that a thread here would reach a wider audience, and may make for a more productive discussion.
